McKesson Foam Back and Lumbar Support Cushion, Black - 18 in x 17 in, 4 Ct

McKesson's back support cushion is a great choice for wheelchair users or people who sit for extended periods of time. Ergonomically designed, the cushion helps keep your head, neck and lower back in proper alignment. Made of high-density polyurethane foam, the cushion's lumbar support can ease lower back pain. A stabilizing board insert helps avoid hammocking for users who are in sling-back wheelchairs. The stretch nylon cover is low-shear, breathable, and removable, unzipping for convenient machine washing. Sliding buckle straps adjust to better hold the cushion in place. Each back support cushion measures 18 inches x 17 inches.
