Office chair details

Our functional Seiza ergonomic chair has been designed to provide exceptional comfort and health benefits for every individual. Its universal design and advanced adjustment features make it the perfect solution for various applications. The modern Seiza office chair features a seat made of integral polyurethane and an aluminum base with the latest-generation mechanism based on gas telescopes. With the use of high-quality materials and exceptional precision, it is incredibly durable. The set also includes rubberized casters, which prevent floor scratches.

One of the key features of our ergonomic chair is the ability to adjust not only the seat height, but also the necessary adjustment of the seat tilt angle to maintain the proper posture. Thanks to this feature, every user can customize the chair to their needs and body structure, resulting in optimal spine support and comfort during prolonged sitting.

This innovative feature of our office chair ensures that the hips and pelvis are in an optimal position relative to the spine, helping to maintain the natural curvature of the back and reduce muscle tension. This is extremely important, especially for individuals who work in a seated position and often experience improper body alignment. It is also an ideal gaming chair for individuals who spend many hours sitting. It works perfectly for professions such as physiotherapists, dentists, architects, and IT specialists. It also serves as a comfortable and functional chair for hairdressers and artists.

Office chair dimensions

ONSEN® offers the Seiza ergonomic chair in one size that is universal for all users. The diameter of the chair base is approximately 70 centimeters, and each of its arms is equipped with a high-quality rubberized caster. The height adjustment of the chair seat ranges from 66 to 84 centimeters from the floor. The seat tilt adjustment is up to 15%.

The chair seat has a saddle shape with dimensions:

43 centimeters in length;
36 centimeters in width.

It is recommended to use the Seiza ergonomic chair with an adjustable-height desk along with appropriate desk risers that raise the desktop. Taking care of your spine requires placing the desk surface at a higher level than in standard desks, which helps maintain the correct posture while sitting.

What sets the Seiza ergonomic chair
apart from other office chairs?

The unique Seiza ergonomic chair, created by experienced specialists from ONSEN®, represents a significant breakthrough in the realm of seating comfort. This exceptional solution is meticulously designed to seamlessly harmonize with the anatomical structure of the human body on a daily basis. Through precise body alignment, the Seiza ergonomic chair effectively corrects posture and promotes the proper alignment of the spine. This is crucial for maintaining its natural curvature.

The remarkable design of this chair allows for achieving a healthy sitting position, known as the "zero gravity position" or zero-G position. Our approach is rooted in a deep understanding of the anatomy and physiology of our skeletal-muscular system. When seated in this ergonomic position, your body is in a state of complete relaxation, eliminating pressure and tension that can arise on traditional chairs. Yet, while sitting in this type of chair, you continue to engage your muscles to maintain balance, preventing muscle atrophy.

Using the Seiza ergonomic chair offers numerous health benefits. The natural body alignment in this position promotes muscle regeneration and optimal spinal alignment. This also enhances breathing efficiency and improves blood circulation, which can positively impact the digestive process by alleviating unhealthy pressure that increases intra-abdominal pressure. This is especially crucial for individuals who spend long hours in a seated position, such as desk workers.

It's worth emphasizing that the Seiza anatomical chair is not only an ergonomic product but also boasts high aesthetic value. Its modern designer appearance fits into various spaces, from contemporary offices to elegant home interiors. The combination of functionality, health benefits, and exceptional design makes the Seiza ergonomic chair an excellent choice for those who seek not only comfort but also care for their health and well-being during extended periods of sitting.

Durable and comfortable seat

01

Adjustable seat height

02

The seat of the Seiza anatomical chair can be adjusted in the range of from 66 centimeters to 84 centimeters from the floor, allowing for customization to different users and tasks. We have implemented a telescopic gas mechanism in it, characterized by high durability and precision, enabling smooth height adjustment.

Expand

The Seiza swivel chair stands out not only with its durable and comfortable seat but also with the possibility of adjusting it to individual preferences thanks to its adjustable seat height. This feature allows for optimal customization of the chair to various needs and situations.

The minimum seat height of 66 centimeters from the floor ensures that the chair is appropriately low, which can be advantageous for low desks or individuals who prefer a lower seating position. On the other hand, the maximum seat height of 84 centimeters from the floor provides full support for users who require a higher seating position at their desk.

This adjustment is made possible by a high-durability and precision gas telescopic mechanism. Thanks to this advanced technology, the seat height adjustment occurs smoothly and effortlessly, eliminating unnecessary effort and complicated adjustments. The gas telescopic mechanism not only ensures convenience but also provides the certainty that the chair will remain stable in the selected position.

The adjustable Seiza chair not only perfectly meets users' expectations in terms of comfort and durability, but also offers flexibility for customization, allowing each user to create ideal conditions for seating and work.

Adjustable seat tilt angle

03

The seat of the Seiza ergonomic chair can be tilted up to 15% to adjust the sitting position according to the user's preferences and type of work. There is an option to lock the seat of the chair at the chosen tilt angle, providing stability during tasks.

Expand

The seat of the Seiza office chair exemplifies a sophisticated and thoughtful design that allows for adjustment of the seating position to individual user needs and the nature of the work being performed. This innovative 15% seat tilt feature enables achieving an optimal sitting angle for enhanced comfort and efficiency.

Thanks to this functionality, the chair user can adjust the seat tilt angle according to personal preferences. Whether one prefers a more upright position while working at the desk or a slightly reclined posture during tasks that require a more relaxed stance, the Seiza swivel chair accommodates full customization.

An invaluable aspect of this solution is also the ability to lock the seat of the chair at the chosen tilt angle. This provides stability during diverse tasks, which is crucial in the context of work and performing precise activities. Whether the user is focused on creative work or tasks demanding greater precision, the Seiza chair ensures an appropriate foundation for achieving optimal results.

The Seiza ergonomic chair with tilt function represents a forward-thinking approach to comfort and support during work. It's not just a chair; it's a tool that enables personalization of the seating position, translating into improved productivity and the quality of daily tasks.

Aluminum base

04

Made from durable materials, the aluminum base of the Seiza office chair serves as a sturdy foundation for the entire structure. Its robust metal construction is also resistant to chemical agents, making hygiene maintenance easier.

Expand

The aluminum base of the Seiza office chair is not only an aesthetic element but primarily a solid and durable construction that forms the foundation of the entire chair. Made from durable materials, the base ensures stability and long-lasting resilience, which is crucial for office chairs used for many hours each day.

Regardless of the intensity of usage, the aluminum base of the chair provides reliable support for the seat and the user. Choosing aluminum as the construction material translates to durability and resistance to loads, enabling peaceful use of the chair for an extended period without concerns about deformations or damage.

An additional advantage of the robust metal construction is its increased resistance to chemical agents. In today's world, hygiene is a priority, especially in office spaces. The aluminum frame of the Seiza swivel chair is designed to exhibit exceptional resistance to the effects of various cleaning agents. This means that the chair can be easily maintained in pristine cleanliness without the risk of material or surface damage.

Rubber casters

05

The Seiza office chair is equipped with five casters that are coated with a layer of the highest quality rubber. High-quality rubberized casters prevent floor scratches and damage while ensuring smooth movement around the office, room, or other spaces.

Expand

The Seiza office chair is not only about comfort and functionality but also attention to details, such as the exceptional rubberized wheels, which enhance the user experience. They set it apart from other swivel chairs available in the market.

The five rubberized casters equipped on this office chair are a key feature that facilitates smooth movement on various surfaces. Furthermore, these casters are coated with a layer of the highest quality rubber, offering numerous benefits.

The most important characteristic of these rubberized casters is their floor protection capability. Thanks to the high-quality rubber, these casters minimize the risk of scratches, abrasions, or other damages that might occur during chair movement. This is especially significant for hard floors like parquet, laminate, or ceramic tiles, which are susceptible to damage.

In addition, the rubberized chair casters provide smooth and quiet movement through space. They allow users to easily change positions, move from place to place without exerting excessive effort or generating noise. Undoubtedly, this contributes to a higher level of comfort and freedom of movement in the office, room, or any other space.

The zero gravity position

The "zero gravity" position is a concept that refers to a body position where the force of gravity has little impact on the body. It's an extraordinary relaxation position where the body is positioned in a way to reduce gravitational pressure on various body parts, leading to muscle and joint relief and promoting overall balance and comfort.

The Seiza ergonomic office chair is designed to allow users to achieve the "zero gravity" position. In this position, the body is placed at specific angles that allow for maximum muscle and joint relaxation. This position offers numerous health and comfort benefits for users.

Research conducted by NASA confirms that a position with an angle of approximately 128° between the torso and thighs is highly relaxing for the human body. The Seiza office chair enables sitting within the range of 125° to 128° angles, bringing users closer to this optimal position.

The Seiza ergonomic chair also encourages the practice of active sitting, which is recommended by many specialists. Active sitting involves dynamic movements and changes in position while seated, aiming to stimulate muscles and improve blood circulation even during sedentary activities.

Choosing the Seiza office chair along with practicing active sitting can create a synergistic approach to maintaining spinal health and overall comfort during work or extended periods of sitting.

Muscles relaxation

Muscle relaxation in the "zero gravity position" is a unique method to achieve a state of body relaxation and comfort. It is commonly utilized in the context of physical therapy, massage, meditation, and in specialized devices such as gravity recliners.

The "zero gravity position" is based on the principle of simulating conditions similar to weightlessness, resulting in the absence of gravitational force acting on the body. In this position, the body is arranged in a way that the spine and other anatomical elements are maximally relieved. As a result, muscles experience minimal tension, and the stress on joints and the spine is significantly reduced. In the "zero gravity position," the body is positioned so that gravitational force is balanced by appropriate body positioning and possibly support from devices. This allows muscles to relax and unwind.

Proper alignment of the spine

Proper alignment of the spine is crucial for maintaining spinal health and avoiding related problems. The "zero gravity position" is one of the effective methods through which a more natural and relieving alignment of the spine can be achieved, positively impacting spinal health.

The spine serves as the central axis of our body and plays a significant role in maintaining posture, movement, and the functioning of the nervous system. In the "zero gravity position," the body is positioned in a way that gravitational force is balanced by appropriate support from the office chair. As a result, the spine does not experience the typical pressure and stress that can occur in vertical or horizontal positions.

Better breathing

The "Zero Gravity" position can have a significant impact on the quality of breathing and improvement of respiratory efficiency by reducing pressure on the chest and diaphragm. This can lead to more efficient breathing and increased oxygen supply to the body.

In traditional sitting or standing positions, gravitational pressure can cause the chest to be slightly compressed, making it difficult for the lungs to fully expand during inhalation. In the "Zero Gravity" position, the body is positioned in a way that avoids exerting pressure on the chest, allowing for freer breathing movements. In the "Zero Gravity" position, the diaphragm is relieved from pressure and doesn't need to work as intensely, allowing it to relax. This, in turn, can help in the more efficient utilization of this muscular structure during breathing.

Better blood circulation

The "Zero Gravity" position can significantly impact the improvement of blood circulation in the body. Due to the absence of gravitational pressure and the proper body positioning, blood can freely circulate, which has many beneficial effects on health.

In the "Zero Gravity" position, blood vessels are less exposed to pressure, contributing to an improved blood flow. Pressure on the lower extremities is greatly reduced, allowing blood to circulate freely with lower risk of stagnation. This can help in reducing swelling. Better blood circulation also means more efficient delivery of oxygen and nutrients to tissues and organs, resulting in better cell regeneration and overall body performance.

Improved digestion

Maintaining proper body posture, including the "Zero Gravity" position, can have a positive impact on improving digestive system function by reducing tension in the abdominal area and gastrointestinal tract. Muscle tension in the abdomen and abdominal cavity can influence the functioning of the digestive system.

In the "Zero Gravity" position, these muscles can relax, helping to reduce tension and improve blood flow in this area. Proper body posture can also support intestinal peristaltic movements, which in turn contributes to smoother digestion. The stomach in this position is not subjected to excessive gravitational pressure or muscular strain, which can enhance the digestion process and prevent potential discomfort. Improved body posture can also aid in the more effortless movement of intestinal gases.
