Comfort meets style. The Adatti™ chair's flexible poly back increases comfort by supporting and conforming to your body, and is available in three colors: Black, White and Green. Plus, it comes loaded with features that allow you to dial in the fit to your sitting preferences. Such as height- and width-adjustable arm rests and pads that support arms and shoulders for comfort. Tilt Lock, which locks the chair in an upright position, giving you the option of sitting perfectly upright or reclined. And Tilt Tension, which controls the rate and ease with which the chair reclines, and provides a pleasant rocking sensation, which may help circulation and to redistribute pressure points during the workday.
