Brolly Sheets provide an easy-to-use, protective solution to a worry-free night. The 100% cotton soft surface provides a natural, breathable and comfortable surface to sleep on. This ensures maximum comfort and a quality night's sleep. You can relax without even thinking about leaks throughout the night with the absorbent qualities holding up to 2 litres/4pints over 8 hours. Brolly Sheets not only provide comfort and protection but ensure maximum discretion with a middle layer that is both quiet and breathable. Brolly sheets feature a polyester-backed polyurethane backing rather than PVC or vinyl, which can omit harmful toxins. 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. The Brolly Waterproof Sheet Protector Double Size is 137 x 95cm and is designed to fit a standard double bed. The sheets are effective in saving you time, money and the need to constantly wash your sheets.
