String ties at the corners hold this 73 inch chaise cushion to the frame instead of letting it slide off when you stand up. The pad divides into three working sections: a 44 inch seat, a 17.5 inch back and a 12 inch head pillow, so it follows the bend of a reclining lounger rather than bridging it. Four inches of high-resilience cotton fill keep its shape through long afternoons and spring back instead of flattening. The polyester and cotton cover resists water and sun, which means the same cushion works on a sun lounger outside or as a floor cushion indoors. It measures 73 by 22 inches overall and weighs 8 lbs, light enough to bring in when rain is coming.
