The chair must provide a comfortable sitting position. • You should be able to easily adjust the height. Minimum range should be 40 to 52 cm (15.5 to 20.5 in) as measured from the floor. • It should have a back support that is adjustable in both height and tilt (0 to 30 degrees backwards). It is important that your lower back be correctly supported (lumbar curve of the back). • You should be able to freely swivel from side to side. • The front of the seat should be curved ("waterfall" edge), and the chair fabric should be breathable. If your chair has armrests, they should be fully adjustable. The arms should not interfere with adjusting the chair or moving it close to the desk. Adjust the chair so that the work surface is at elbow height. If the chair has an adjustable seat pan, inclining the seat slightly forward will transfer some of the pressure from the spine to the thighs and feet. This will relieve spine fatigue. Use a chair with an adjustable lumbar (back) support, which can be moved up and down. Adjust the back of the chair so that the part that curves outward (toward the front of the chair) corresponds to the part of your lower back that curves inward. (Portable lumbar cushions are also available at medical and office supply houses.) Adjust the angle of the back rest and seat tilt so that your back is erect or angled slightly backward (90 to 110 degrees) Some people feel more comfortable up to a 135 degree angle. YOUR POSTURE While sitting at your workstation, your back should be erect or angled slightly backwards. Your back should be supported by the backrest.
