SafeRest Premium Cotton Waterproof Mattress Protector review

SafeRest's Premium Cotton protector is the classic terry-topped cover, and it is the best fitted option here for most families. The surface is cotton terry over a membrane back coating, which SafeRest says protects against fluids, urine, perspiration and allergens while staying noiseless and breathable. Terry soaks up moisture on the surface, so small spills and sweat do not sit on top. It comes in every size from crib to California king, goes on like a fitted sheet and is machine washable and dryer safe. A twin cost $39.99 on SafeRest's US store when we checked, with a 10-year warranty, free shipping and 30-day returns, and SafeRest reports a 4.6 star average across more than 280,000 verified reviews of its protectors. Two caveats: the product description uses the word water-resistant, and like all fitted covers it protects only the top of the mattress. For heavy nightly accidents, put it over a six-sided encasement.
