    A mattress is one of the most significant investments you’ll make for your bedroom, so keeping it protected from spills, stains and everyday wear is essential.

    Crafted with a 100% cotton quilted surface and a generous 120gsm filling, it adds a soft, cushioned layer that improves the feel of your mattress without trapping heat. Beneath the quilting sits a TPU laminate waterproof backing, a quiet, flexible layer that shields your mattress from moisture, perspiration, accidents and spills. Antibacterial properties help reduce allergens, supporting a fresher, more hygienic sleep environment.

    Designed like a fitted sheet, the protector features a fully elasticated skirt with a generous 15" depth, ensuring a secure, smooth fit for mattresses between 10" and 15" deep. It’s easy to remove, machine washable and fast drying, making everyday care simple.

    Available from narrow single to super king, this protector extends the life of your mattress while adding comfort and confidence to every night. Pair it with our waterproof pillow protectors for complete bed protection.

    CAN AN ELECTRIC BLANKET BE PLACED BENEATH THIS PROTECTOR ?

    Asked by: PAULINE

    We would not recommend using an electric blanket beneath this waterproof mattress protector, as the waterproof layer may limit the effectiveness of the heat. Please always follow the electric blanket manufacturer’s care and safety guidance.

    Are these protectors noisy and plastic like ?

    Asked by: Billie

    No, Belledorm waterproof mattress protectors are designed to feel soft, quiet, and comfortable, not plastic-like. The protector has a smooth cotton  surface that sits gently beneath your fitted sheet, so the sleeping surface remains soft and natural against the skin.

    Beneath the fabric is a waterproof backing that protects the mattress from spills, moisture, and everyday wear. This layer is flexible and breathable, so it moves naturally with the mattress and does not create the crinkly or rustling sound often associated with older plastic protectors.
