This gracefully designed chair features an upholstered back and seat to comfortably get you through your work day or to keep you comfortable while browsing the internet. This chair features an ergonomically contoured back and seat and arms that are comfortably padded. High back office chairs extend to the upper back for greater support and relieve tension in the lower back, preventing long term strain. The contoured seat dissipates pressure points for greater comfort. The waterfall front seat edge removes pressure from the lower legs and improves circulation. The tilt lock mechanism rocks/tilts the chair and locks in an upright position while the tilt tension adjustment knob adjusts the chair's backward tilt resistance. 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 nylon base with caps prevents feet from slipping when resting on chairs base.
