Dimensions: Unfolded dimensions are 46.4 inches x 50.4 inches. (Chair not included). Compression packaging results in the cushion being relatively flat. Don't worry. Simply pat it a few more times and wait a few days for it to return to its original shape. Washable/Removable Cover: The replacement cushion features a zipper design, allowing for easy removal and cleaning of the cushion cover. The non-woven fabric wraps the interior, and the PP cotton is easy to remove and refill. Headrest: Fits your head to help you better relax your cervical spine and relieve cervical pain. It also protects your coccyx and hip joints. Anti-slip Straps: There are straps on both sides of the seat cushion for better fixation on the egg chair, making it less likely to move. Versatile Cushion: Suitable for hammocks, swing chairs, rocking chairs, rattan chairs, and living rooms. Can be used on indoor or outdoor garden furniture.
