White cotton jersey mattress protector with a thin waterproof polyurethane layer. As the protector is 100% waterproof, it protects the mattress from liquids and moisture, while its high level of breathability allows air through. The protector can be used without a fitted sheet as the texture of cotton jersey is soft and pleasant to the touch, providing a better night's sleep. Adjustable for easy placement. Features elastic around the edges to ensure a proper fit. Suitable for mattresses of up to 15.7" thick. The protector comes in a cotton jersey bag, the same fabric as the protector. This allows for easy transport and storage.
