Our waterproof covers are made to fit US manufactured bed sizes. We offer mattress covers that fit both regular (10") and deep (16") beds. For best value and longest life we suggest our pure polyurethane UltraFlex products for lowest cost over time. It is not unusual for UltraFlex mattress covers to last 2 years. Our Durasoft mattress covers will fit both a regular and deep mattress and is a long life stay soft vinyl material that is an excellent value. NOTE: Novelty print mattress covers are not as long lasting as our plain styles due to the printing. But they are cute and fun!
