This is the Wilson Beds PVC Waterproof 6.5" Deep Mattress. Designed with both value and leakage in mind, the PVC waterproof mattress is ideal for anywhere where there is a chance of leakage. This foam-free design is primarily aimed at the younger generation but can be used for adults or as a guest room mattress. It is built around the traditional 13.5-gauge open coil spring unit that forms the core support mechanism of more UK mattresses than anything else. This is encased in environmentally friendly spring insulator pads made almost entirely from recycled fabrics. On top of this goes the polyester comfort layer. The majority of the fibres in this soft cushioning pad are made from recycled plastic bottles. This is then bordered and topped off with the PVC-coated waterproof fabric to protect your mattress from leaks. The result is a low-cost, medium-feel waterproof mattress free from volatile organic compounds. Please open your mattress (without using sharp objects) within 7 days of receipt and allow it to air for 24-48 hours in a dry, well-ventilated room so that your new mattress is acclimatised and fully inflated before use.
