1.EXTRA THICK CUSHION FOR MORE COMFORT This cushion for patio chairs made of waterproof polyester fabric is easy to clean and maintain. It does not shrink and wrinkle and retains its shape even after prolonged use. Our pillows are made with comfort in mind, filled with high quality PP cotton, have quick rebound, not easy to deform and withstand the test of time. 2.Size Seat Size: 45 x 19 x 4 inches. The backrest is higher than most other rocking chair cushions, which makes the neck better supported. This soft cushion is suitable for Adirondack chairs, rocking chairs and patio chairs for indoor and outdoor use. 3.Nonfading and deforming The color fastness of our pillow is level 4, so it will not fade in the sun. The stitched positioning thread construction prevents the cushion filling from shifting and bunching, which provides more comfort. Whether lounging in the afternoon sun or enjoying an evening with friends and family, these cushions will give Adirondack chairs a comfortable and stylish upgrade. 4.Nonslip settings There are ties on the sides of the cushion that allow the cushion to be attached to the chair. The elastic band on the back fits different chair sizes, so the cushion does not accidentally slide forward. These nonslip settings ensure that the Adirondack cushion stays securely in place for optimal comfort.
