A classic blue chaise cushion is a low-effort way to bring a coordinated look to a poolside lounge chair or patio deck chair. It fits chairs around 21 inches wide by 72 inches long and is padded with 4 inches of high-density foam that evenly supports your back and legs instead of packing down after a season of use. The 180 g/m² polyester cover is treated to resist water and UV50+ rays, so pool splashes and long days in the sun won't leave it damp or faded. Sectioned to follow the folding hinges of a standard lounge chair, the cushion stays flat and supportive whether the chair is upright or fully reclined. Ties along the back keep it anchored to the frame so it won't slip off during a breezy afternoon, and the reversible design means you can flip it over for a fresh face once one side starts to wear. Confirm your lounge chair measures close to 21 by 72 inches before ordering.
