Our protectors are the gold standard in protection! Made of soft cotton terry backed with a breathable polyurethane film, our mattress & pillow protectors repel liquids and stains while allowing body vapor to breathe. The revolutionary barrier fabric also prevents bacteria and dust mites from breeding (a major cause of asthma, eczema and rhinitis). Remember...it only takes one accident to spoil a good mattress, pillow or duvet. A must for families with children and household pets! These mattress protectors go on just like a fitted sheet and also help with "sheet creep"!
