About Office Chairs

Your chair is your most intimate belonging at the office. Such an intimate relationship demands an office chair with functions to accommodate your body structure and work environment.

Stress on your spine is greater when you sit as opposed to stand, so an ill-fitted office chair can cause or worsen existing physical conditions that result when muscles and joints are forced into awkward positions for long periods of time.

Proper adjustment of your office chair will add to your comfort, productivity and reduce your risk of injury. Some people even find it helpful to adjust their chair throughout the day, to accommodate different tasks.
Currently, there are no restrictions on the term "ergonomically designed" when selling office furniture, so remember the following when purchasing an office chair:

Seat Height - if set properly, your thighs will be parallel to the ground and your heels will be flat on the floor.

Seat Depth - with your back against the backrest, the seat should support most of the length of your thighs, without feeling pressure on the back of your knees.

Lumbar support - should feel firm support at the lumbar curve of your back.

Contouring - should allow free movement and back support.

Seat covering - should breathe.

Armrests - should adjust to half an inch or more below your elbow. While typing, your arms should be able to swing easily.

Waterfall seat - offers a 5% backward slope, promotes the use of the backrest and prevents you from sliding forward.

The Base - five casters prevent the chair from tipping, and should roll easily over carpet.
