ADI suspension technology

Each ADI chair is equipped with the SUSPENSION SYSTEM.

Created by ADI, this highly ergonomic process frees the body from any contact with a rigid surface. The tension of braided polyethylene belts on a metal frame ensures comfort, lightness and well-being. Thanks to the Suspension technology, no rigid surface is in contact with the body after compression of the foam and flexing of the elastic belts under tension. The ischium, hip bone and vertebrae are supported by a more even distribution of forces.

Why an ergonomic chair?

According to the CCOHS, injuries resulting from sitting for long periods of time can be a health and safety issues in the workplace. It is clear that office work requires less muscular effort but people who work in a sitting position are not exempt from the risk of injury.

What to look for when selecting an ergonomic chair?

Here are the things to consider when buying an ergonomic chair:

Leg length is the determining factor here. To properly adjust the height of the seat, the feet must be flat on the ground with no pressure on the lower thigh. The weight of the body should be evenly distributed among the feet, thighs and buttocks.
Not all models offer adjustable seat depth. Adjusted seat depth (the distance between the front of the chair and the backrest) ensures proper support for the thighs and prevents circulation from being cut off behind the knees. Optimal seat depth is achieved when you can slip four fingers between the front of the chair and the back of the knees.
The backrest is adjusted mainly for the purpose of increasing or decreasing support to the lumbar region. This adjustment is essential to maintaining the natural curvature of the spine when leaning on the backrest. During adjustment, it is important to try various positions until the backrest fits perfectly.
When seated, people change positions constantly to keep the blood circulating in the muscles of the thighs and buttocks. On a fixed seat, there is a tendency to slouch, which is bad for the curvature of the back. A chair with adjustable reclining motion offers a greater range of movement to the user. It allows users to change positions from time to time while maintaining good posture, to lean back while on the phone, to read documents, or to speak to a co-worker, for example. Apart from the reclining motion itself, the resistance encountered when reclining is an important factor in proper chair adjustment. Reclining tension should be set to prevent the user from falling backward, while allowing the user to recline comfortably and without straining.
Armrests support the elbows and allow the shoulders to maintain a relaxed posture. Resting the elbows on the armrests rather than on a desk prevents users from leaning forward and thus placing pressure on the elbows. A good armrest is sufficiently wide and cushioned. Ideally, armrests should be adjusted by width, height and depth (back to front). In terms of width, armrests should be adjusted according to the width of the shoulders. The user's arms should not be too close to the body, but slightly apart. Likewise, if the armrests are too far apart, the user may lean to the left or right and sit in a bent position. As for height, the armrests should be adjusted to suit the shape of the user’s shoulders (straight or relatively curved) and arm length. The armrest should support the elbow and part of the forearm when horizontal. Working with hunched shoulders should be avoided. The depth of the armrests should be adjusted to allow the user to sit sufficiently close to the work surface.
The headrest is of particular importance for users who are often reclined. For regular office work, the headrest is not necessary. The headrest should be adjusted to support the head in a normal, straight position, without pushing the head forward or letting it fall back.
