Office chairs are a part of the décor of any office and so many people try to make sure they look good without worrying about the health influences the chair will have on the person who uses it. The design or ergonomics of the chair should be considered above everything else.
Lumbar Support: A good office chair will have support for the lower back. Some of the better ones will even have an adjustable lumbar support that allows the user to fit the chair to their lower back. This is important in preventing back strain that can worsen and become sciatica, a condition which can be debilitating.
Adjustability: Almost all office chairs have a height and arm adjustment; however, these are not the most important adjustments to look for when shopping for an office chair. The best office chairs have at least five adjustments with some having up to 14 different adjustments.
Important features that should be adjustable include lumbar support, arm width and height, seat back width and height, seat and back angle, and tension control. Many of the supports are dial controlled while a few are controlled with a hand-held bulb pump, similar to a blood pressure cuff pump.
Wheel Base: Nearly all office chairs have a wheel base; however, if the office is carpeted it may be necessary to get a chair with wheels specifically made for carpet. Rolling is important in preventing strain due to reaching across a desk to retrieve items that are out of reach.
Swivel Base: All office chairs should swivel freely to allow for easy access to various parts of the desk. If the chair doesn’t swivel freely, arm fatigue can result from over extending to reach various items.
Fabric: The fabric should be breathable to keep the chair from becoming hot and uncomfortable after hours of sitting in it. In addition, it should have enough cushion to support the person sitting in it without feeling the base of the chair through the cushion.
