Sustainable Fabric Seaqual is made from recycled plastics gathered from the ocean, that’s then upcycled into threads and woven directly into the quilting on the top of the mattress. The natural Silk and SEAQUAL® textiles in the mattress are naturally soft, breathable and moisture wicking. The range is endorsed by the Australian Physiotherapy Association (APA) and comes with a 90 Day Comfort Guarantee.
