Most office chairs are equipped with a set of wheels, usually four or five. Five wheels give the greatest stability, which is important if you're a secretary whizzing back and forth between the copier, computer, and coffee machine. Smooth running wheels also come in handy for those impromptu games of office hockey.
Arm rests lend an air of dignity and comfort to an office chair.
A swivel chair is a must.
Office workers spend a lot of time on chair, make sure the chair is comfortable. A high back takes tension away from the lower spine, and prevents long term strain. A sloping seat front allows the greatest blood circulation, and reduces "numb leg".
Office chairs usually come equipped with some sort of adjustments. The most important of these is seat lift. Make sure the height of the seat can be changed so that legs are parallel to the ground, with feet resting flat.
Most chairs also allow peoppe to tilt the whole chair forward or backward. The best position keeps person’s back straight, vertical to the ground, while a backward tilt comes in handy for those all-so-important power snoozes. Make sure it doesn't tilt back too far, though. Nothing spells disaster quite like falling backwards out of your chair while you're in a board meeting.
