Brolly Waterproof Sheet Protectors provide an easy-to-use, protective solution to a worry-free night. The sheets are manufactured with a 100% soft cotton top, ensuring maximum comfort and a quality night’s sleep. The absorbent middle layer and waterproof, yet breathable backing keeps the bottom sheet & mattress dry. Brolly Sheets not only provide comfort and protection but ensure maximum discretion with a middle layer that is both quiet and breathable. For use, you can simply place your Brolly Sheet on top of the fitted sheet and tuck the wings in under the mattress. This provides an excellent layer of protection to keep the bottom sheet, mattress pad & mattress dry. It is recommended that you wash this prior to use as this will soften the fabric and increase the product's absorbency. Brolly sheets feature a polyester-backed polyurethane backing rather than PVC or vinyl, which can omit harmful toxins. The Brolly Waterproof Single Sheet Protector in King size is 165 x 95cm and is designed to fit a standard King size bed. The sheets are effective in saving you time, money and the need to constantly wash your sheets. For use, simply place the product on top of the bottom sheet and tuck the wings in under the mattress. Please wash separately prior to use as this will soften the fabric and aid absorbency. The product is machine washable at 40 degrees.
