The soft seat also tilts forward to relieve pressure on thighs when in a work-intensive position. Optional memory foam seat enhances comfort even further.Whether you adjust seat depth, back height or arm height, Engage ergonomic task chairs pivot to fit your body and adapt to your tasks. Back flexes 20 degrees yet can be locked in any of three positions. Controls are also easy to access and grasp.
