<p>BackStrong C1 Task Chair is made to move. Patented, Sit in Motion technology is ingeniously designed to mimic your pelvis, making it the first and only chair that can induce perfect posture and give you the freedom to move.

Created by a chiropractor and industrial product designer, the unique seat moves with you to protect against pain while stimulating circulation, improving flexibility and bringing oxygen to your muscles. This slouch-proof task chair fits the curve of your spine perfectly, cradling your pelvis and lower back so your vertebrae stack into ideal posture. Foldaway, PU arm pads allow you to move much closer to your desk for reduced eyestrain. Unsurpassed lumbar support keeps you comfortable all day long. Task chair also features soft high-grade, vinyl upholstery, pneumatic seat-height adjustment, 360-degree swivel and smooth-rolling casters.</p>
