Mattress layers
All four layers of the Osaka Air foam mattress are made from the highest quality and also fully safe and hypoallergenic polyurethane foams with open cells.
  • HR30100 is a high-resilience foam with a density of approximately 30 kg/m3 and a firmness of about 100 N according to the ILD method and about 2.0 kPa according to the CLD method.
  • V50075 is a memory foam with a density of approximately 50 kg/m3 and a firmness of about 75 N according to the ILD method and about 1.5 kPa according to the CLD method.
  • HR35120 is a high-resilience foam with a density of 35 kg/m3 and a firmness of about 120 N according to the ILD method and about 2.4 kPa according to the CLD method.
  • HR50190 is a high-resilience foam Richlux® High Resilience HR50038 with a density of approximately 50 kg/m3 and a firmness of about 190 N according to the ILD method and about 3.8 kPa according to the CLD method.
In the HR35120 foam layer, there are transverse ventilation channels and an Aero 3D mesh built with microfilaments. In combination with the three-dimensional ventilation openings in the mattress cover, they create a system for removing excess heat and moisture from the mattress. This helps maintain proper air circulation, enhancing sleep comfort.
+
Bed frame
In contrast to many mattress manufacturers, ONSEN® does not recommend a specific type or model of mattress base. Instead, we advise that it be made of durable materials characterized by the appropriate width and thickness. These should be selected so that the mattress does not sink but is stably positioned on the base. At the same time, the spacing between the slats should allow for unrestricted air circulation.
+

How is it possible that the Osaka Air
is a foam mattress for everyone?

Is it possible to create one mattress that will be suitable for everyone? Yes, it is! Our produced Osaka Air mattress is a solution that meets the expectations of all users regardless of their preferences and needs. Allow yourself comfort and a healthy sleep using our innovative approach to mattress design!.

Our functional Osaka Air mattress is perfect for you and your family. It is a product that has been designed with diverse user needs in mind. Every element of this mattress has been perfected to perfection during the design, research, and testing process involving specialists participating in the design thinking process, which we successfully apply to our products. They are all also created in line with the jobs to be done concept, making them fully functional.

Designing the iconic Osaka Air foam mattress is based on an interdisciplinary approach that incorporates knowledge from orthopedics, neurology, physiotherapy, and psychology. As a result, this comfortable mattress not only provides comfort but also the support necessary for the regeneration of your body during sleep.

The final firmness of the Osaka Air mattress has been optimized to meet the needs of people sleeping in different positions. It rates 6.5/10 on the American mattress hardness scale. In the Polish scale, it would be a H3 mattress, although it is arbitrary and lacks scientific basis. Therefore, it is the best mattress for side and back sleepers, as well as for most stomach sleepers. Adapting the universal firmness of the mattress to the sleeping position translates into providing optimal spine support throughout the night.

Our design process, as well as user research and experiences, have allowed us to dismiss the misconception related to choosing a mattress by weight, which makes no sense. The world of science clearly proves that it is the proper match of mattress firmness to sleeping position that is crucial for sleep hygiene. Body weight is proportionally distributed across the mattress surface, providing the same support to individuals of different body builds.

It is worth noting that the Osaka Air mattress does not contain latex, buckwheat, coconut, or other potentially allergenic materials, making it an excellent choice for allergy sufferers. It meets the expectations of a wide range of users, also serving as an excellent complement to rehabilitation and treatment for people suffering from spinal problems.

Remember that...

Each copy of the Osaka Air mattress is produced no earlier than 2-3 weeks before shipment, which is due to the technologies we use. It is a fresh product that reaches you immediately after the foam seasoning process, which takes place inside. Also, the material from which we make the mattress cover is completely new. This may affect the initial impressions when verifying the mattress's firmness, which is due to the stiffness of the materials. Wait for the real experiences associated with its use. The intended firmness and elasticity will undergo final changes within 15-30 nights of use.

Air circulation

HR30100 | 3cm
open-cell high-resilience foam
The first layer of the Osaka Air foam mattress is made of high-resilience HR30100 foam with a thickness of 3 centimeters. The designation HR30100 means that this type of HR foam has a density of about 30 kg/m3 and hardness of approximately 100 N (about 2.0 kPa). It is a unique foam in a blue color, which is the official color of the ONSEN® brand.

The purpose of the first layer of the Osaka Air mattress is to provide the right dynamics and elasticity. It also offers optimal support for the body, especially the spine. Its use over memory foam is intentional and aims to avoid the sinking of the body during sleep while ensuring proper ventilation.
V50075 | 4cm
Thermoelastic foam (memory foam)
The second layer of the Osaka Air foam mattress is made of V5015 memory foam with a thickness of 4 centimeters. The designation V50075 means that this type of memory foam has a density of about 50 kg/m3 and hardness of approximately 75 N (about 1.5 kPa).

The purpose of the second layer of the Osaka Air mattress is to allow it to conform to the body by eliminating negative sensations related to body pressure on the mattress. It enables the proper distribution of weight accumulation points, promoting blood circulation and proper body regeneration at night. Placing it in the second layer of the mattress eliminates body suction into the mattress and sweating while allowing a change in sleeping position.
Aero 3D | 1cm
microfilament ventilation mesh
The Osaka Air mattress features a specialized Aero 3D mesh layer, approximately 1 centimeter thick, placed between the third and fourth layers of the mattress. The mesh is made up of thousands of microfilaments that allow for full air circulation and are resistant to compression.

The purpose of the Aero 3D mesh is to provide a unique level of ventilation for the mattress that is not commonly found in other mattresses on the Polish market. Its innovative construction ensures an unprecedented level of air circulation in the mattress, which cannot be achieved by simple ventilation holes or channels alone. This layer helps to remove excess air and moisture from the mattress, significantly increasing its hygiene.
HR35120 | 4cm
Highly elastic open-cell foam
The fourth layer of the Osaka Air foam mattress is made of HR35120 high resilience foam with a thickness of 4 centimeters. The designation HR35120 means that this type of HR foam has a density of about 35 kg/m3 and hardness of approximately 120 N (about 3.0 kPa).

The purpose of the fourth layer of the Osaka Air mattress is to support the layers above. It is also responsible for enhancing its elasticity and hardness, as well as providing a smooth transition to the lower layers. This layer contains a system of cross-ventilation channels that work in conjunction with the Aero 3D mesh and breathable cover, creating a cohesive mattress ventilation system.
HR50190 | 10cm
Highly elastic open-cell foam
The fifth layer of the Osaka Air mattress is made of HR50190 high resilience foam with a thickness of 10 centimeters. The designation HR50190 means that this type of HR foam has a density of about 50 kg/m3 and hardness of approximately 190 N (about 3.8 kPa). It is the only foam in the mattress with a red color, known as Richlux® High Resilience HR50038.

The purpose of the fifth layer of the Osaka Air mattress is to ensure the stability of its entire surface. This is particularly important when using the mattress on continental beds or structures that are not beds. Additionally, it is essential when two users with different weights sleep on the mattress, preventing the lighter person from being pulled towards the heavier one.
Air circulation
Air circulation in the Osaka Air foam mattress reduces difficulties associated with overheating and sweating during sleep. This is made possible by a specially designed ventilation system, which consists of an innovative cover, Aero 3D mesh, and cross-circulation channels. Thanks to them, it is possible to remove heat and moisture from the mattress.

Functional foam mattress for sensible people

The Osaka Air is an innovative foam mattress with medium firmness. It is created by the Polish brand ONSEN® originating from Toruń. It is characterized by a firmness of 6.5 on our adopted 10-point American mattress hardness scale, which corresponds to an H3 mattress in the Polish hardness table. We consciously decided to refrain from marking the mattress in the Polish hardness scale, as it lacks any standardization.

ONSEN® is the only manufacturer to implement an innovative mattress ventilation system that removes heat from the depths of the mattress to the outside. This makes the Osaka Air mattress solve the problem of sweating at night. Air circulation in ONSEN® mattresses is at the highest level.

Perfect air circulation!

01

The unique arrangement of the layers of the Osaka Air foam mattress ensures the highest level of air circulation on the market, which reaches up to 92%. Thanks to this, the Osaka Air foam mattress prevents overheating of the body and, consequently, sweating while sleeping.
Expand

The results of consumer research have proven that about 50% of mattress users are dissatisfied with them due to overheating of the body, as well as excessive sweating while sleeping.

Sweating at night is most often the result of sleeping on thermoelastic mattresses, also commonly known as memory mattresses. These are the mattresses whose first layer is memory foam, which is a specific type of polyurethane foam.

One of the disadvantages of memory mattresses is the mirror effect of heat. It consists in accumulating heat coming from the body of a person sleeping on a mattress, and then giving it back to him.

In addition, shape memory mattresses do not ensure proper air circulation due to the extremely poor dynamics of thermoelastic foams, as well as the closing of their cells under the influence of pressure and human body temperature.

The layered Osaka Air foam mattress prevents the increase in body temperature during sleep, and also eliminates the problem of night sweats. This is due to the thoroughly thought-out, tested and repeatedly appreciated by customers structure, which is the result of the design thinking process.

The first layer of the Osaka Air foam mattress is 3 centimeters of highly elastic HR3020 foam, whose open-cell structure allows for optimal air circulation. At the same time, the hardness and density of this polyurethane foam, combined with the other layers of the mattress, provides adequate support for the body and spine during sleep.

Only the second layer of the Osaka Air foam mattress consists of 4 centimeters of thermoelastic foam V4515. Due to the lack of direct contact with the sleeping person, it does not give the effect of a mirror reflection of heat and does not disturb the air circulation of the first layer of the mattress.

At the same time, the use of V4515 thermoelastic foam in the second layer of the Osaka Air foam mattress affects its highest comfort and perfect fit to the body. Not, however, as in the case of thermoelastic mattresses, by its suction, but by its contouring.

In addition, in the Osaka Air foam mattress, under the layer of thermoelastic foam V4515, an innovative, unprecedented ventilation system has been placed. It consists of a modern Aero 3D mesh made of thousands of microfilaments, as well as a carefully designed system of transverse channels.

The mattress cover also plays an important role in the ventilation system of the Osaka Air foam mattress. The one at the height of the transverse channels is made of an original mesh that ensures perfect air circulation.

All this allows you to remove excess heat and moisture outside the mattress while maintaining the best air circulation on the market. Among other things, it is thanks to this that the Osaka Air foam mattress remains the best highly elastic mattress on the market, which cannot be matched in quality.

Up to 100 days to return the mattress!

02

At ONSEN®, everyone has 100 days to return a mattress. If you return your Osaka Air Mattress within this time frame, we'll refund your money at no extra charge. We realize that a mattress cannot be tested in a store, and it takes time at home.
Expand
We realize how important it is to test the product before making the final purchase decision. Especially when the product is a mattress. There is no other product that would be so important for our functioning, and at the same time it is used in conditions of complete relaxation and unconsciousness.

We also know that testing a mattress in a stationary store is completely pointless. It is impossible to assess the functionality of the mattress while fully clothed and fully aware. Especially in front of other people and under the observation of a convincing seller who uses his sales tricks on us.

Many studies say that at least about 30 nights are needed to assess the functionality of a mattress. During this time, the human body will get used to the new mattress, which is a key element of sleep hygiene. During sleep, which takes place in a state of complete unconsciousness, we spend on average as much as 1/3 of our lives!

Buying a mattress, contrary to appearances, is not an easy task. That's why the Osaka Air foam mattress can be tested in your own bedroom. By extending the time necessary for this, we allow you to return the mattress up to 100 days after purchase. During this time, you can use our mattress without any restrictions.

Sleep on a mattress, rest on it, read books or drink coffee. Let children jump on it and let pets lie on it. Treat him as you will treat him for years to come. Only in this way will you be able to really test the mattress.

ONSEN® additionally exposes the unfair practices of many mattress retailers and only offers mattresses online, and therefore only in direct sales. This allows not only to return the mattress, but also to reduce the price of products by omitting the high margins of sellers.

Freedom to change your sleeping position!

03

The Osaka Air foam mattress is the perfect choice for everyone, regardless of sleeping position. It also does not make it difficult to change position during the night, giving full freedom of movement.
Expand
The use of HR3020 highly elastic foam in the first layer of the Osaka Air foam mattress, and only in the second layer of the V4515 thermoelastic foam, translates into the freedom to change the sleeping position.

Most users of thermoelastic mattresses report that they suck them into the mattress and prevent them from changing their sleeping position. This is due to the fact that the memory foam, which is in their first layer, collapses under the influence of body temperature and pressure.

This effect is completely natural in memory mattresses, but extremely uncomfortable for users. They are surrounded by a layer of polyurethane walls that prevent movement and do not allow air to pass through.

It can also be dangerous. Collapsing in the mattress precludes placing the body and spine in a physiological position, which can have negative health consequences. And for the elderly and people with mobility difficulties, getting up from a thermoelastic mattress requires the use of techniques that often result in injuries.

By transferring the V4515 thermoelastic foam to the second layer of the mattress, we have eliminated this defect. However, we still use all the advantages of memory foam. Such a unique solution eliminated the feeling of sinking in the mattress, replacing it with comfortable contouring of the body shape.

In combination with the other layers, the Osaka Air foam mattress provides the best dynamics among the mattresses available on the market. It allows both the freedom to change the sleeping position and comfortable support while sleeping. In addition, it does not transfer movements, isolating them around the moving person, which increases sleep satisfaction for other people. It is also a fully sex-friendly mattress, ready for new sensations.

Perfect body support!

04

All layers of the Osaka Air foam mattress are designed so that each of them has a specific functionality. Their combination ensures maximum sleep comfort with ideal support for the body, as well as support for maintaining the physiological position of the spine, hips and limbs.
Expand
In the Osaka Air foam mattress, we used the jobs to be done methodology. We assumed that the most important thing in a mattress is not the mattress itself as a thing, but its functionality. They are tasked with fulfilling specific tasks, performing the expected work.

We buy mattresses not just to have a mattress, but above all to get a good night's sleep. This must be accompanied by comfort, as well as ensuring a certain sleep hygiene. Consequently, the mattress cannot cause any negative feelings, but it must deepen positive impressions.

Thanks to having a functional mattress, we increase our sleep comfort and, consequently, the regenerative capacity of the body. The position of the body during sleep, regardless of the sleeping position, has a key influence on this.

The layers of the Osaka Air foam mattress are designed in a way that provides optimal body support. Thanks to the use of materials with carefully selected hardness and density, the Osaka Air foam mattress supports the even distribution of weight accumulation points.

As a result, it allows you to keep your spine, hips and limbs in a physiological position throughout the night. This also translates into the satisfaction of many customers who have found out that the Osaka Air foam mattress is both a solution to their difficulties and fully meets their expectations.

The unique construction of the Osaka Air foam mattress uses the advantages of all polyurethane foams used in it, while eliminating their disadvantages. The person sleeping on the Osaka Air mattress does not sink into its depth and does not overheat.

It meets all 10 conditions that an ideal mattress should have, making it the best mattress available on the market. At the same time, it is an orthopedic mattress, registered as a first class medical device.

Up to 15 years warranty!

05

ONSEN® provides a 15-year warranty for the Osaka Air foam mattress insert and a 2-year warranty for its cover. Its conditions are clear and transparent, which additionally distinguishes our mattresses, orthopedic pillows and other products from many other offers.
Expand
The mission of ONSEN® is to offer the highest quality products that will retain their properties and serve for years. We are guided by an ethical approach to complaints and returns. We believe that consumer rights are violated too often, which we do not agree with.

To meet the expectations of consumers, as well as being sure of the highest quality of our products, we provide up to 15 years of warranty! Our warranty periods are:
  • 15 years for the core (insert) of the mattress;
  • 2 years for mattress cover;
  • 10 years for the core of orthopedic and classic pillows;
  • 2 years for the cover for orthopedic and classic pillows;
  • 2 years for the rest of the assortment.
The indicated 15 years is, in our opinion, the optimal time, which is supported by market research, as well as observations of consumer behavior and their expectations. However, we set this time mainly based on hygiene issues.

The Osaka Air foam mattress we offer after the warranty period has expired, i.e. after 15 years, will still have the same shape and retain its qualities. The results of scientific research, however, say that replacing the mattress after this time is already a necessity for hygienic reasons.

Smart mattress cover!

06

Our smart Osaka Air mattress cover is made of the highest quality fabric with multi-directional elasticity, mesh that is part of the ventilation system and material with a non-slip coating. It is possible to take it off and wash it.
Expand
Each Osaka Air foam mattress is equipped with an intelligent mattress cover, which was designed by top-class specialists cooperating with ONSEN®.

The mattress cover used in the Osaka Air foam mattress is fully flexible. It is produced in a technology that ensures its multi-directionality, which translates into an even distribution of physical forces in many directions at the same time.

We made it from a fabric with a weight of 550 g/m2, which, combined with flexibility, makes it an extremely durable product. In addition, it is extremely pleasant to the touch, which is due to the use of a fabric with an appropriate weave.

Its side part is made of a unique mesh. Its use is an important element of a modern system of heat and moisture removal outside the mattress. It is also an element that distinguishes the Osaka Air foam mattress in visual terms.

The underside of the Osaka Air foam mattress cover is made of a material with a unique non-slip coating. It prevents the mattress from sliding on the frame or bed frame, as well as on any other surface. Thanks to this, the Osaka Air foam mattress does not move and remains in the same place, which increases the safety and comfort of its use.

The Osaka Air mattress cover has a zipper and can be washed according to the instructions on the laundry tag. Although it is obvious to us, many mattresses still do not have this option.

Safe foams!

07

Only safe, thoroughly tested polyurethane foams from the world's best manufacturers are used for the production of the Osaka Air mattress. They have safety certificates, and their foaming takes place in Poland.
Expand
The substrates for the production of polyurethane foams used by ONSEN® come from BASF Germany, which is one of the most respected producers in the world. At the same time, they are the best researched and most extensively tested polyurethane foams, which are characterized by the highest biological purity. Thus, their use is completely safe for health.

Although polyurethane foams from the People's Republic of China, which are used by most of the leading mattress manufacturers, would be much cheaper, they do not meet the stringent quality standards of ONSEN®. Therefore, the Osaka Air mattress is not the cheapest mattress. At the same time, the use of a low margin allows us to sell it at an affordable, fair price.

The work on the Osaka Air mattress lasted several years, during which we sought advice from people with extensive knowledge in the field of neurology, orthopedics, physiotherapy and psychology. In addition, we deepened our knowledge about the technology of materials from which we make ONSEN® products.

After several years of testing prototypes of the Osaka Air mattress by healthy people as well as people with various diseases, we have developed an optimal distribution of individual layers of the mattress. The result of our work is the creation of a mattress that provides the highest level of comfort, perfect body support and spine support, as well as the best ventilation on the market.

We have nothing to hide, which is why we do not use trade names of materials that we use to produce the Osaka Air mattress that are incomprehensible to customers, but their official designations. For this reason, we openly say that - for example - the lowest layer of our mattress is 10 centimeters thick and is made of open-cell, highly elastic HR foam with the designation HR4037. This means that it has a density of 40 kg/m3 and a hardness of 3.7 kPa.

We openly oppose the lack of transparency in determining the physical parameters of polyurethane foams used in mattresses. We are of the opinion that transparency in this matter is the duty of every mattress manufacturer. Although it is common practice to hide them and hide behind trade secrets, ONSEN® fulfills this obligation.

For every sleeping position!

The universal firmness of the Osaka Air mattress allows you to sleep in all three positions: on your side, on your back and on your stomach.

Although in Poland the phenomenon of determining the hardness of a mattress as H1, H2, H3, H4 or even H5 still dominates, at ONSEN® we realize that the hardness of a mattress should be determined on a numerical scale. In addition, it should depend on the sleeping position, not the weight of the mattress user.

Looking at the US mattress firmness table based on sleeping position, the ideal mattress to sleep in any of the three positions is a mattress with a firmness of 6.5 - medium firm. This is the hardness we gave the Osaka Air mattress. Although we could present it in the Polish scale as an H3 mattress, we oppose its unscientific basis.

Safe for allergy sufferers!

For the production of the Osaka Air mattress, we use biologically clean materials that allow it to be easily kept clean. The textiles from which the mattress cover is made are hypoallergenic and can be washed.
Expand
In the production process of the Osaka Air mattress, we use only polyurethane foams and biologically clean textile materials. They have the appropriate certificates, including Oeko-Tex 100 Standard and CertiPUR.

The Osaka Air mattress cover is hypoallergenic yet very easy to clean. Thanks to this, you can get rid of possible allergens, including house dust mites.

In addition, it does not cause unpleasant situations that occur in other types of mattresses, such as the famous worms in a coconut and buckwheat mattress or the negative impact of a spring mattress on health.

Folded, not rolled up!

10

ONSEN® does not iron or roll its products. That's why the Osaka Air mattress is folded in half and then packed only on the day of shipment. In this form, it can be stored by the client for up to 6 months!
Expand
Many of our customers ask us not only about which mattress to choose, but also why it is important not to iron or roll the mattress. The answer to this question is very easy for ONSEN®.

A compressed and rolled mattress kept for many days in a cardboard box may have up to 35% of damaged foam cells. This shortens its service life by up to 50%! It often happens that a rolled mattress does not return to its original shape after opening the package. No wonder, because the presses used exert a pressure of over 10 tons on the mattresses!

The Osaka Air mattress offered by ONSEN® is packed only on the day of shipment. We do not roll it, but fold it in half, which distinguishes us from other manufacturers. Thanks to this, we protect its interior against degradation, which allows you to enjoy its properties.

Unlike compressed and rolled mattresses, the Osaka Air mattress can be used immediately after taking it out of the carton, and stored in the carton for up to 6 months without any damage to the polyurethane foams contained in it. Their quality parameters mean that they will retain their properties even after prolonged storage.
For these questions
answer
is YES!
+
Can I really return the mattress before 100 days?
Yes! ONSEN® products, including mattresses, can be tested without restrictions in the comfort of your own bedroom for up to 100 days. During this time, you can return it to us and we will send the received money.
+
Is the Osaka Air mattress a thermoelastic mattress?

Yes and no. A traditional thermoelastic mattress has a layer of visco polyurethane foam, i.e. memory foam, as the first top layer. This causes the sleeping person to be sucked into the mattress. The result is overheating and sweating of the body, limiting movement and the ability to change the sleeping position. In the Osaka Air mattress, thermoelastic foam is the second layer. Thanks to this, we use its advantages, but we have eliminated its disadvantages!

+
Is the Osaka Air mattress for everyone?
Yes! The universal Osaka Air mattress is a highly elastic mattress with optimally selected hardness, density and thickness of individual layers. This mattress properly supports the body of every person and provides him with perfect support for the spine. It is not dependent on the weight of the user. It is a myth that a slim person should sleep on a soft mattress referred to as H1, and a heavier person on a hard mattress referred to as H4. The number of support points in these people is different, and in the end they exert pressure on the mattress in a very similar way.

Most frequently asked questions by customers

Can I use the Osaka Air mattress right after delivery?
Yes, you can. Your new Osaka Air mattress is ready to provide you with the highest sleeping comfort right after delivery as it is not rolled up. It can be stored in its packaging for up to 90 days.

Do I need to flip the Osaka Air mattress to extend its lifespan?
No, you don't. Your new Osaka Air mattress is one-sided. It has a properly designed layered construction that is responsible for its functionality. To extend the lifespan of the mattress, you can rotate it horizontally (head to foot) from time to time, which will allow you to enjoy it for longer than the warranty period (15 years).

Should I use a protector to protect the Osaka Air mattress from damage?
Your new Osaka Air mattress is equipped with a cover with a weight of 550 g/m2, as well as an additional protective material placed on the core of the mattress. It is enough to protect it with an ordinary sheet. The protector should be used only when necessary, e.g., when sleeping with a baby or in other situations that may cause excessive soiling.

Should I expect a certain adaptation period to the Osaka Air mattress?
Your new Osaka Air mattress is tailored to the human body structure. Usually, no adaptation time is needed. It may be necessary for people who have previously slept on an unhealthy, non-ergonomic surface. The duration of such adaptation is variable and usually does not exceed about a month. The rule is that the more inappropriate sleeping surface one had previously, the longer the adaptation time to sleeping in physiological positions may be.

Is the Osaka Air mattress a medical product?
Yes, it is. Your new Osaka Air mattress is a Class I medical device. It has properties that are beneficial to health. It works perfectly in the prevention, treatment, and rehabilitation of spine diseases.

Does my mattress have any weight or height restrictions for users?
No. Your new Osaka Air mattress can be used by people of different weights and heights. The weight distribution points are proportionally spread over the surface of the body, which means that sleeping on it provides the same sensations to everyone.

On what bed frame can I use the Osaka Air mattress?
Your new Osaka Air mattress can be used on any surface. It is suitable for placement on both flexible frames and rigid ribbing. It can also be placed on pallets or a solid foundation. However, it is important that the surface is always even. It is also recommended that it has appropriate ventilation holes.

How do I clean the cover of the Osaka Air mattress?
Your new Osaka Air mattress comes with a removable cover that can be easily washed in an automatic washing machine. The top part of the cover is suitable for washing at 40°C using standard laundry detergents. The bottom part of the cover, which contains silicone threads, should be hand washed or washed on a program designed for delicate fabrics at a temperature not exceeding 30°C, as otherwise they may shrink.

How do I clean the foam core of the Osaka Air mattress?
Your new Osaka Air mattress is made of high-resilience (HR) and thermoelastic (V) foams, which should not be washed as it can damage their structure and make them difficult to dry. To maintain appropriate hygiene, it is recommended to frequently ventilate the mattress and periodically expose it to temperatures below 10°C, which helps to eliminate dust mites. Ozone treatment of the air in the bedroom also has a positive effect, which should be done using professional companies.

What are the recommendations for temperature and humidity in the bedroom when using the Osaka Air mattress?
Your new Osaka Air mattress does not require special conditions in the bedroom. It is designed for the variable atmospheric conditions that exist in Europe. It should not be exposed to extreme temperatures that are not normal in Europe. Because it contains thermoelastic foam in its second layer, its firmness may slightly vary depending on the temperature. It will be slightly firmer at low temperatures and softer at high temperatures.
