Unlike other waterproof protectors ours is breathable, allowing body heat to pass through it and provide a comfortable and cool sleep surface. This is imperative for Memory Foam beds that require body heat in order to conform to the curves of the human body. The mattress protector is not only durable, but also thin enough that it does not change the comfort or feel of the mattress. Protecting a brand new mattress with our Mattress Protector will stop bacteria and dust mites from taking up residence in the mattress. Fitting a mattress with a protector cuts off the food supply for dust mites, leaving them unable to survive. These creatures live on the skin flakes, body oils and moisture people lose every night during their sleep. Our mattress protectors and allergy encasements provide a barrier that won’t let these items through to the mattress. Our mattress protectors feature a 10 year warranty. When the mattress protector is purchased on the same retail sales receipt as a new mattress, not only is the protector warranted against material or manufacturer defect, it also warrants the new mattress against surface stains for that same 10 year period.
