Waterproof Mattress Protectors

A waterproof mattress protector is the easiest way to keep your mattress clean and extend its life. It stops spills, sweat and accidents soaking through, so you just wash the protector instead of replacing the mattress.

SAIMAZ waterproof mattress protectors have a waterproof layer that guards against spills, stains and accidents while staying comfortable to sleep on. Choose a quilted protector for extra softness or a bamboo protector for a smooth, cool surface. Deep elasticated skirts keep them in place – our bamboo and 30 cm quilted protectors fit mattresses up to 30 cm deep.

Sizes include Bunk Bed, Single, Small Double (4ft), Double, King and Super King – so there is a fit for children's beds, guest rooms and the main bedroom. Machine washable. Using a topper too? Browse our mattress protectors and toppers.

Free UK delivery in 2–4 working days and free 30-day returns on every SAIMAZ order.
