The first key setting of the chair is the seat height. This is usually the front lever on the right hand side of the chair. The correct height is generally achieved when the user's elbows are at (or just above) the keyboard height. (if the elbows are below keyboard height the user tends to unconsciously hunch up their shoulders to lift their arms a little).

If this height lifts the user's feet off the floor they may be most comfortable using a footrest. Well supported feet mean better low back support and better neck/shoulder posture. If the feet are not well supported the user's bottom tends to slide away from the backrest and this hunches their posture and can lead to soreness developing (especially back, neck & shoulder pain). Note: not all footrests are created equal – be sure to get a solid footrest that can be set close to flat, won't slide away or fall apart and is easy to adjust.

The next key setting is the height of the backrest. Most people let their backrest drop down too low – which gives inadequate support to their low back or their shoulders. Raise the backrest height so that the curve of the backrests fits snugly into the user's small of the back.

Now set the angle of the backrest. We recommend a slightly reclined posture at 100-110 degrees, rather than the old 90-degree upright posture. This allows the user to REST on the backrest. And the user’s neck and shoulder muscles are less tense as well (we've tested this using Electro Myography EMG measuring devices).
