Review on Everest Encasement Waterproof Hypoallergenic Zippered by Chris Drury

This mattress pad is a great fit for our RV sofa bed Air Dream Mattress. A depth of 9-11 inches is ideal when the top of the airbag mattress is inflated and the stretch pattern of the material will not leave excessive bulk or bulge on the deflated mattress when folded back into the sofa when the Air escapes before the zipper completes. Zipper at one end and two adjacent sides approximately 24 inches. Wraps around the mattress like a pillowcase. We inserted the mattress from the bottom up where the zippers line up, so we only need to open the corner on both the cover and mattress pad to inflate the mattress chamber. Water resistance has not been tested, but the lining is formulated to repel liquid to protect the mattress while remaining soft and quiet. Great protection and added confidence for a new RV mattress.
