Ergonomic design delivers exceptional performance. Optimized for lasting comfort, the ReGeneration by Knoll Fully Upholstered High Task Chair boasts an innovative design that provides adaptive support without interruptions. A fully upholstered back covers the slim, high-performance elastomer Flex Back Net frame. Integral lumbar support reduces strain to the back area. Its Flex Seat with three sides of seat edge flex and seat depth adjustment allows you to sit in any position and supports your body as it turns 270-degrees. Four independent flexors respond to multidirectional movement, and a weight compensated Dynamic Suspension control mechanism provides a smooth, synchronized recline. Recline resistance feature provides greater upright support. Set-back arms include contoured arm pads and are height adjustable to ensure leg clearance and continuous lumbar support when side sitting.
