Fits patio dining chairs — Seat: 21' W x 19' D; Back: 21' W x 23' H Key benefits Comfortable support: Thick 4' memory foam with a 100% foam core provides soft, elastic cushioning that absorbs pressure and reduces discomfort on hard chairs. Designed to resist deformation for extended sitting. Durable for outdoor use: Fabric treated for UV and waterproof performance.

Quick setup: Delivered vacuumpacked. Unzip the package and the cushion will regain shape—typically within 5 days. To speed smoothing of creases, you may use a garment steamer on the cover.
