Sit at your desk a lot more comfortably with the black Kensington's SmartFit Conform Back Rest, featuring a patented back support technology. Strap it around virtually any standard-size chair and customize its height to your personal comfort for maximum support for your spine and lumbar. There's a comfort color bar that helps you choose the optimal height.
The back panels are designed to conform to your body type via four independent springs that articulate when you shift your posture. Moreover, the panels are ventilated so you always stay cool and dry as heat dissipates away. The fabric cover is removable and machine-washable.
