Does the hand test make sense?

Why do we have only one mattress model?
We encourage you to explore our series of videos called Krótka Piłka (Quick Facts), which was created in response to our customers' requests. This series takes the form of a Q&A, where we answer questions related to mattress or pillow selection and the purchasing process. The collection of questions comes directly from customers, as well as individuals contacting us for advice from our specialists.

 

 

In the second episode of the series, we answer questions related to choosing a mattress for sleeping. They primarily concern the budget for mattress purchase, which can sometimes be low. We also talk about night sweats on the mattress. We explain where double-sided mattresses came from and whether they are functional.

Does the hand test make sense?

Mrs. Monika from Tarnow asked us why most salespeople in brick-and-mortar stores often start by asking about the budget for the mattress. The salesperson she encountered tried to explain to her that the price of the mattress determines its quality. This raised doubts for the customer because she had heard a similar statement from other salespeople as well. However, she wants to buy a good mattress at a reasonable price.

In our opinion, when a salesperson asks about the budget, it should raise a yellow flag in our minds. If the salesperson in the first few questions asks about the budget, they want to know how much they can profit from us. Because the salesperson offers mattresses ranging from 2000 Polish zlotys to 15,000 Polish zlotys, customers get a sense of the mattress's value. However, this sense can be deceptive.

If a good foam mattress costs around 5000 Polish zlotys, with a weight of approximately 38 kilograms, for a size of 160x200, we can say that it is a decent mattress. Such a mattress probably won't sag too quickly because the foam density speaks to its durability. However, there's no rule that a mattress weighing 60 kilograms will be better because at some point, the density may become too high. The best weight for a 160x200 mattress is between 35 kilograms and 45 kilograms, and these are the foam mattresses worth considering.

The reason a salesperson asks about the budget for a mattress is simple. If we say we have 4000 Polish zlotys for a mattress, they will try to sell us one for 5000 Polish zlotys, just slightly more expensive. However, it doesn't necessarily mean it's a better mattress, only that they can make additional money from us. The construction of many mattresses in brick-and-mortar stores doesn't differ much, and the same mattress can cost from 1500 Polish zlotys to 11,000 Polish zlotys or more.

Are polyurethane foams produced in Poland?

Mrs. Paulina from Warsaw asked us about sweating on an inappropriate mattress. She mentioned that she bought a mattress for 7900 Polish zlotys, and unfortunately, its first layer contains memory foam, as recommended by the seller. At home, she discovered that this type of polyurethane foam sinks and heats up. She feels deceived and has noticed that many people complain about such mattresses.

Mattresses made of memory foam cause sweating problems for most users. Of course, this is not a rule, but around half of their owners report this issue. Demonstrations using balls or water bottles have no bearing on comfort. It is clear to us that memory foam should not be in the mattress's top layer if it is to be comfortable and healthy for the user.

The absence of specific parameters for polyurethane foams leads customers into confusion and error, as well as a refusal to provide essential characteristics of the goods, which is detrimental to consumers. The seller is obliged to provide the buyer with the necessary explanations regarding the products before entering into a contract. Failing to provide information about the complete parameters of polyurethane foams that make up the core of the purchased mattress constitutes a violation of legal obligations, which is indisputable. Let's exercise our rights and request a mattress return under warranty.

Why do we have only one mattress model?

Mrs. Julia from Kielce asked us about our honest opinion regarding double-sided mattresses as she has come across conflicting information. On one hand, mattress sellers often praise them, but the scientific knowledge we advocate suggests that they are merely a marketing gimmick. She has also encountered various opinions on such mattresses.

As we often emphasize, a double-sided mattress should, in our assessment, never exist. We are deeply concerned by how frequently they are purchased. Imagine having a memory foam mattress described as double-sided. In the first layer, there is soft HR foam that is a few centimeters thick. Below it is another type of polyurethane foam meant to serve as its core. Lastly, at the bottom of the mattress, there is viscoelastic foam, also a few centimeters thick.

If you lie on top of this mattress model, on the high-resilience foam, the bottom layer of the mattress will become almost flat. This is due to the fundamental properties of viscoelastic foam. It adjusts itself to the bed frame, not the body, as it doesn't have direct contact with it. However, if the upper layer of high-resilience foam has the right density and firmness, it can be comfortable.

Flipping this mattress to the other side will simply cause the soft HR foam in the bottom layer to compress because it is soft. The user will lie directly on the viscoelastic foam, which lacks supporting properties, and thus, it will sink. This type of foam surrounds us but does not push back. It lacks proper resilience, which negatively affects the mattress's dynamics.

Importantly, in both cases, at least one layer of such a mattress will be flatter than the other. As a result, it may turn out that the mattress cover will be less fitting, and the mattress itself will become less functional. The same phenomenon will be visible in the case of a spring mattress, where there will be an additional layer of coconut or felt insulating the steel from the foams.

We also encourage you to explore other articles on the best sleep and health blog, as well as the Encyclopedia of Healthy Sleep prepared by the ONSEN® team of specialists. For those who care about spine health, we recommend a set of spine exercises prepared by our physiotherapist.

FAQ: Quick Ball (2)

Does the price really reflect the quality of a mattress?

The price of a mattress is not always an indicator of its quality. Many mattresses in similar price ranges can have similar specifications and properties, so it's worth investigating other characteristics, such as weight or foam density. You should also always inquire about the foam parameters and the functionality of the mattress.

Why do memory foam mattresses cause night sweating?

Memory foam mattresses often lead to issues with night sweating because they can heat up during the night. This is due to the phenomenon of heat retention. Memory foam should not be in the top layer of the mattress for it to be considered comfortable and healthy.

Are double-sided mattresses a good choice?

Double-sided mattresses have their limitations. Flipping the mattress can affect its properties, but it is rarely beneficial. This does not impact the longevity of the mattress itself.

Why do salespeople often ask customers about their mattress budget?

Many salespeople inquire about the budget for a mattress to tailor the price of a certain type of mattress to the customer's affordability. They often try to sell a more expensive mattress, even if it is not of better quality than a cheaper model or if their interiors are the same.

What parameters of a foam mattress should be taken into account?

When choosing a foam mattress, it's important to pay attention to its weight, which should be between 35 to 45 kilograms for a size of 160x200, as the weight and density of the foam reflect its durability. You should also always ask for the complete parameters of polyurethane foams, including their type, density, and hardness.
