This washable zip-on mattress protector is available as a perfect fit for your Jay-Be Folding Bed mattress. Guarding your mattress against liquids, stain damage, dust mites and allergens, the cover is also extra soft, so it doubles as a comfortable fitted sheet to sleep on. Covering the whole mattress, and unlike other waterproof covers, its high-tech membrane is silent and flexible for ultimate protection without that unpleasant plastic feel. The cover's micro-pores also allow air to flow freely for a fresher and healthier sleeping environment.
