How to Sit – Features of an Ergonomic Chair
An ergonomic chair is a great piece of equipment to relieve the symptoms of back pain, especially if you remain seated for a long period of time. There are several features of an ergonomic chair that are crucial to ensuring comfort. This article gives advise on how to sit properly.
Features of an ergonomic chair
The chair needs to be easily height adjustable. This would normally operate via a lever on the side of the chair that uses a pneumatic system to adjust the height.You should be able to sit comfortably with your feet flat on the floor, arms at the same level as your desk so that they are near enough touching your computer screen. It can also be useful to have adjustable arms to make using equipment on the desk easier.
Seat width should ensure that the user has enough space to sit in the chair comfortably, and a a seat- slide mechanism is also a good way to make sure that the user can sit with their back against the backrest while leaving space between the back of their knees and the front edge of their chair. Additionally the material on the seat and the back needs enough padding to be comfortable to sit on for extended periods of time without creating pressure points under the sitting bones. A high quality worsted wool upholstery fabric that ‘breathes’ and gives a degree of resistance to sliding is ideal.
A backrest that articulates separately from the seat, adjustable in both height and angle is best. Lower back support in an ergonomic chair is extremely important. The lumbar spine has an inward curve. Sitting for long periods of time without support for this curve therefore tends to lead to slouching and forcing the curve outward. Ideally an ergonomic chair should have a separate lumbar adjustment to fine tune to your unique shape.
Finally an ergonomic chair should move easily and without conscious effort, so encourage you to move continuously, varying your posture to suit the task at hand. There is no ‘perfect posture; the best posture is always your next one! Hope this helps you understand how to sit properly and the benefits of sitting properly.
