- Removable and easy to clean: The washable replacement cover for the hanging chair cushion features a zipper for easy removal and washing. An independent inner lining keeps the cotton filling wrapped, so removing the outer cover won’t cause the filling to shift. - Outdoor-ready and compatible: Made from high-density polyester, the cushion is sun-resistant and scratch-resistant. The cover cleans easily with a damp cloth. Designed for use with hanging chairs in the garden or on the patio, it stands up to sun exposure and outdoor use. - 8 inch thick memory foam filling: The thick hammock cushion is filled with memory foam, soft and comfortable, with good resilience and it will not flatten. At 8 inches thick, it provides solid support compared with typical 6 inch cushions, helping protect your tailbone and hip joints. - Headrest and integrated armrests: Ergonomically designed to provide ample space to stretch. With a headrest, integrated armrests, and a backrest, it feels like a mini sofa, making it ideal for reading, chatting, or other activities.
