Synchronous mechanism
One of the main advantages of the mechanism is that the seat and backrest are not connected. When the backrest moves, the seat moves in the same direction in a certain ratio (usually 2:1 or 3:1). This gives a more pleasant sitting sensation and reduces the load on the back muscles. The chair's synchronous control mechanism allows to lock the tilt angle to the desired sitting position.
As the chair swings freely, the synchronous mechanism actively maintains an optimal and ergonomic seating angle. The firmness of the chair's oscillation can be adjusted individually according to the weight of the sitter. Ergonomic office chair SITNESS LIFE 50 with pneumatic lift easily raises or lowers to the desired sitting
height. The Ergonomic chair SITNESS LIFE 50 with synchronous mechanism is recommended
SYNCHRONOUS MECHANISM
SITNESS mechanism
SITNESS is an ergonomic dynamic mechanism. It has been medically proven that the chair’s three-dimensional dynamic mechanism resembles sitting on a ball – the seat moves forward, backwards and sideways with the body, adapting to the body’s movements. This makes for a very comfortable seating experience, as the back muscles are not strained – sitting in this chair relaxes the intervertebral discs in the spine, which improves blood circulation.
Although the benefits of SITNESS have been proven by medical studies, some clients find the dynamic mechanism uncomfortable and unstable. If you are unsure whether SITNESS is really for you, we recommend that you contact one of our consultants or try out a chair with the SITNESS mechanism in person in our showroom.
SITNESS LIFE 50 is also recommended by our partner HEALTHY BACK SCHOOL.
SITNESS MECHANISM
Ergonomic desk chair SITNESS LIFE 50 with 2D armrests
The armrests of this chair provide support for the arms. This reduces tension on the arms, shoulders, neck and hand muscles. This is particularly important when sitting for long periods of time. When work is finished, the armrests can be used as a support when standing up, thus reducing the strain on the pelvic muscles.
The armrests can be raised or lowered to the desired position with the push of a button. If the armrests are locked too high or too low, they may interfere with your body movements and cause discomfort.
It is recommended to choose an armrest position that allows the arms to be bent at about 90° while sitting at the desk, with the shoulder blades naturally relaxed and in a straight horizontal line. It is important to ensure that when sitting in a chair, the legs of the person should be at a straight 90° angle to the floor.
SITNESS LIFE 50 is an excellent ergonomic solution. If you have any questions about how to adjust your ergonomic chair, please contact our consultants.

Tapestry seat
The seat of this chair is covered with a soft tapestry fabric. This type of fabric is particularly popular because it is soft and pleasant to the touch to the skin and is available in a wide range of colours. Tapestry chairs match easily with the surrounding furniture and décor. Tapestry is a relatively hard-wearing and durable material, so the chair can be used comfortably for many years.
It is worth noting that tapestry seats are sometimes can become a popular place for cats to scratch their claws. Before buying an office chair, assess your pet’s tastes. If you think this may be a problem, we suggest you contact our experts to find a solution that works for you.
Breathable tapestry backrest
BREATHABLE TAPESTRY
Adjustable backrest height
SITNESS LIFE 50 has a height-adjustable backrest. Often the backrests are slightly curved to replicate the curve of the spine. The height of the backrest of the chair allows to adjust so that the lumbar region of the body is comfortably supported and there is no discomfort.
Height adjustment allows the backrest to be adapted to different people of different heights and body shapes. The adjustable backrest height is a great feature for chairs that will be used by more than one person or for tall/low people. For more information on how to adjust your chair correctly, read our blog or contact our consultants.
BACKREST HEIGHT ADJUSTMENT
Ergonomically shaped seat
Office chair SITNESS LIFE 50 has an ergonomically shaped seat. The moulding follows the shape of the body, distributes the weight of the body and prevents the pelvis from sliding towards the front of the seat. Maintaining the correct seating position maintains correct back posture, resulting in less fatigue and back pain.
It is worth noting that in rare cases, for extremely tall or short people, seat moulding may not fully conform to the shape of the body or may otherwise cause discomfort, If you would like to find out more about whether seat moulding is right for you, we recommend that you contact one of our consultants or visit our showroom.
Classically shaped backrest
Ergonomic office chair SITNESS LIFE 50 has a classically shaped backrest. This type of backrest provides comfortable back support for people of all heights and body shapes. For some customers ergonomically shaped backrests are not comfortable and sometimes cause discomfort. Classically shaped backrests are more likely to make it easier to find a comfortable sitting position. It is worth noting that the shape of the backrest is a very personal choice. If more than one person will be using this SITNESS LIFE 50 chair, or if you are not sure which back shape would suit you best, we recommend that you try it out live in our showroom.
11 mm castors (for soft floors)
Ergonomic chair SITNESS LIFE 50 is with castors for soft flooring. If the chair is used on hard flooring (wooden flooring, parquet, laminate), the surface may be damaged or scratched over time. Our specialists recommend that you purchase additional castors for hard flooring. Wheel axle 11 mm. The castors are made of thermoplastic elastomer, sometimes called thermoplastic rubber, which is a physical mixture of polymers consisting of materials with both thermoplastic and elastomeric properties. These wheels are softer and do not scratch hard flooring.
We recommend purchasing a plastic mat under the chair to protect the more sensitive floor covering. If a stable, fixed seating position is desired, we recommend chair feet instead of castors. When choosing chair castors, it is very important to pay attention to the type of use and the floor covering, if you are not sure we recommend you contact our consultants or visit our showroom.

Height-adjustable table
Our specialists recommends taking breaks during work based on medical research. Taking a 15-minute break every 45 minutes to move around. Prolonged sitting in one fixed position increases the likelihood of chronic pain and cardiovascular disease. We recommend combining seated work with standing work, together at a height-adjustable table! Learn more
Chair feet
When you buy an office chair, we often get questions about whether the castors can be replaced with feet. Of course! An office chair with feet is stable and its functionality remains unchanged. This is especially true for workplaces where there is a small, limited working area and stability is needed: shops, warehouses and production companies. People with disabilities or elderly customers often ask for chairs with feet. Learn more.
