4 Treston Workplace Chairs A workplace chair must be equally good fit for anyone and everyone – men and women, small people and large, heavy and light, and young and old – which is why it is essential to have a sufficiently wide range of settings and adjustments. See here the different adjustment possibilities of Treston workplace chairs. Adjustments and features of Treston workplace chairs Permanent contact backrest … follows the movements of the upper body, and ensures that the back always remains fully supported. Ideal for people who have to lean forward for long periods of time, with only a small distance between eyes and workplace (e.g. working in precision engineering or in the laboratory). Synchronous mechanism … provides an active-dynamic sitting experience with weight regulation. The seat and backrest accompany to body as it moves. This gives the user a feeling that can best be described as ”weightless floating”. The synchronous technology comes into its own where users are working at office type working situations, working at a screen, or constantly changing their sitting position. Armrests Armrests have the important function of reducing the strain on the upper body and arms. The height, width and depth of 4D armrests can be adjusted, and can also be swiveled. Backrest height Ensures that a person is ideally supported – especially in the lumbar region – no matter how tall he/she is. Weight regulation By individually adjusting the pressure of the backrest, both light and heavy people can sit with the correct posture. Seat depth Matches the depth of the seat to the size of the body, giving the best possible contact surface for the thighs. Contact with the backrest, and therefore the support it provides, are maintained. Seat tilt Many jobs are carried out in slightly raised positions, and require people to bend forwards. A correspondingly tilted seat provides a seat angle of at least 90 degrees, while at the same time providing contact with the backrest. Seat height Allows adjustment to body size and height of workplace. The ideal seat height is when the knees, hips and elbows form an angle of at least 90 degrees, with the feet resting flat on the floor.
