AllerEase is the best mattress protector. It’s waterproof for those spills, easy to clean if liquid seeps through the sheets. It’s allergy free which is great during spring season. It protects the mattress from bedbugs which is a plus in case bedbugs do come in through travel etc. the zipper gives the mattress a nice fit. Overall it’s a great mattress protector to protect your mattress for it to last long.
