Crafted from 200 thread count sustainable, organic cotton, our premium warming mattress protectors have a cloud-like softness so you can drift off cocooned in warmth. They are available in five sizes and thanks to an elasticated skirt with a depth of 38cm, they are easy to slip on. Even better, the natural fibres keep you toasty in the winter but cool in the summer, it is simply mother nature with a welcome warming boost.
