These environmentally friendly cushion inserts are filled with 100% PET fibre, which is derived from recycled water bottles. They look and feel similar to a high-grade polyester cushion insert, but have a greater resilience rating and will last for much longer. For every 1kg of fibre used, more than 70 water bottles are saved from landfill. Non-Allergenic – Machine Wash – Line Dry. Sized at 22x 22in they are the perfect size for our outdoor cushions. International customers please note: we are unable to ship cushion inserts overseas.
