The mattress consists of deep comfort fillings with a traditional European engineered Bonnell spring unit and a layer high quality next-generation viscoelastic memory foam for that extra comfort and support for a great night's sleep. An average of 230 plastic bottles have been carefully recycled into the new innovative Seaqual fabric which is used for the top panel and border of the mattress. The mattress collaborates with fishermen, researchers, scientists, authorities, and private stakeholders to clean our oceans of marine litter. Each mattress is made from Seaqual Yarn which is a high quality 100% post -consumer recycled polyester and is made from 10% Upcycled Marine Plastic with the remaining 90% is post-consumer PET from land resources. The open construction of the filling is a knitted cove, means our revived mattresses are breathable, moisture-wicking, and will regulate your body temperature providing a cooler and more soothing night's sleep.
