The Cuddledown Pure Cotton Mattress Protector is a quilted cotton pad that sits between you and the mattress. Diamond quilting adds a soft, breathable layer without the bulk or crinkle of a waterproof membrane. Elasticated side skirting holds it in place, and it comes in a standard depth for mattresses up to 30cm and an extra deep version for up to 40cm. It suits sleepers who want breathability and a little extra cushioning rather than spill protection, and it was named Glamour's best cotton mattress protector for 2026.
