These outdoor chair cushions turn a bare patio set into a place worth sitting. The set includes two 20 in. x 20 in. x 4 in. seat cushions, each built with a high-density, high-resilience foam core that holds its shape through long afternoons outside. The covers are treated to stay waterproof and fade-resistant, so they keep their look through sun, rain, and poolside spray. White piping traces the edges for a clean finish, and matching ties lock each cushion to the chair frame so it stays put on windy days. When the covers pick up dirt, the zipper opens and the covers go straight into the washing machine, then back on for a fresh, like-new seat. Available in four colors, these cushions fit most standard outdoor chairs and give the patio a tidy, inviting update.
