This luxurious Pure Cotton mattress protector is ideal for adding protection and preventing stains, the build up of allergens, and prolonging the life of your mattress. With a 100% cotton cover, filling and skirt, this protector allows for a more comfortable and breathable sleep. This protector has a 200 thread count cover and skirt with elasticated fitting and a 38cm skirt to fit any mattress. Cotton is naturally hypoallergenic and temperature regulating, meaning this protector can be used year-round and is free from any harmful chemicals or dyes. At Lancashire Textiles, we understand that your mattress is an investment, and this protector helps prevent discolouration, general wear and tear and helps your mattress stay clean and fresh for longer. Cotton will naturally shrink with laundering, but this protector has been designed to take this into account and retain its shape. We do not recommend using this mattress protector with an electric blanket as this will significantly limit its effectiveness.
