The importance of a good office chair should not be underestimated - millions of us spend on average 6–10 hours a day sat on an office chair.
A good chair will provide the correct lumbar and pelvic support which results in your back muscles being less stressed, and more productive you.

The key to this healthy posture is lumbar and pelvic support
Seat Height and Width
The seat height of your office chair should be fully adjustable and positioned so that your feet rest flat on the ground with your thighs resting horizontally. The width of the seat cushion should also allow you to sit with your back resting against the backrest with around four to eight centimetres of space between the backs of your knees and the seat.
Lumbar Support
Your back is designed to curve through the length of your spine, so a good ergonomic chair will have an adjustable back that shapes to the curves of your lower back perfectly, preventing you from slouching after prolonged periods of sitting down.
Seat Material
Soft, cushioned seat pads are recommended for office chairs rather than hard textured surfaces, this is to ensure comfort for the user.
Armrests
The armrests of your seat should be adjustable allowing you to sit comfortably with your shoulders in a relaxed position. Your elbows should be able to rest on the armrest; however your lower arms and wrists should not be resting on the arms whilst you are typing.
Swivel
The chair should be able to turn easily allowing the user to reach areas of their desk without straining themselves by trying to drag the chair along, for example.
