The Lorell Hi-Back Chair Mesh Headrest is designed for use with the matching chair, model 85561. It attaches easily to the chair with a screw for quick and easy assembly. The soft, comfortable nylon material provides a comfortable support for your head so you maximize your productivity. This Lorell headrest adjusts in height to just the right position for your comfort. If you spend a lot of hours at your desk, either at home or in your office, this component lets you create the sitting position that works best for you. The black chair headrest is gentler on your neck, back and upper body than having no support at all.
