This gel memory foam cushion provides support wherever you take it, whether it's in the car, on the couch, at a desk, in a dorm, on a plane, or at the movies. In addition, the ergonomic cushion is a great gift for those with pain from sitting or who must sit for long periods. A machine-washable cover makes cleaning the cushion a breeze. Remove the cover from the gel core, spot-clean stains, or toss the cover in the washing machine. Avoid tailbone pain with firm support. A cut-out in the middle of the cushion helps distribute your weight evenly to eliminate aches. The gel core works well for those with arthritis, joint pain, and other health issues exacerbated by sitting. Memory foam conforms to your shape, providing customized assistance. A non-skid, textured bottom means you can place the foam seat cushion in any seat, and it will stay there without sliding around even as you get up and sit back down. In addition, it's sized to fit into most standard chairs with ease. No assembly is required to use the foam cushion. Place it where you wish to bolster your experience and increase joint support as you sit.Details:Blue and gray18.25" x 14.25" x 2.75"Removable, washable coverMemory foam with gel coreFits most standard size chairs
