2. The Adjustable Arms
Armrests help to reduce tension in the upper body and allow the shoulders to relax.The arms of an orthopaedic chair should be adjustable in 3 dimensions to allow the user to place their forearms in the most comfortable position. Soft padding on the arms is also necessary for added comfort.

Support to the lower back is an essential part of what makes an orthopaedic chair. It prevents slumping and reduces stress to the spine and hips. An adjustable backrest should allow the user to align the curve of the chair with spine.
4. The Materials
A good ergonomic chair uses the best mesh and fabrics. Due the climate in East Africa, it is essential the material allows the users back to breathe instead of sweat, choosing a mesh chair really enhances comfort for the user. Seat padding should be moderate not too hard that it causes pain and not to soft that it’s not firm to support the user.
5. The Adjustable Seat Depth
Good orthopaedic chairs come with a seat sliding depth adjustment mechanism to allow the user to align their body to allow the back and upper leg to be at 90° which is gives the optimum comfort level. Whether you are tall or short you can always adjust the depth to your most comfortable position.
6. The Adjustable Seat Height
The optimum seat height is whereby the user is able to place both his/her feet flat on the ground while seated. The back, upper leg and lower leg should all be at 90°. Therefore a good orthopaedic chair should have an adjustable seat height that the user can either lower or increase the height to their desired position.
