This unique designed office chair folds if you have the need to slide under your desk or give your office an open feeling when not in use. The two thumb sliders placed on the sides of the chair make it an easy transition to get to the folding position. Finding a comfortable chair is essential when sitting for long periods at a time. Having the support of an ergonomic office chair may help promote good posture and reduce future back problems or pain. High back office chairs have backs extending to the upper back for greater support. The high back design relieves tension in the lower back, preventing long term strain. The waterfall front seat edge removes pressure from the lower legs and improves circulation. Chair easily swivels 360 degrees to get the maximum use of your workspace without strain. The pneumatic adjustment lever will allow you to easily adjust the seat to your desired height. The heavy duty nylon base is trimmed in silver adding to the contemporary design.
