This is the most expensive, waterproof mattress cover sold by newton. Unfortunately, the first time I washed and dried this one it got ruined. They sent me two new replacements. It’s still in usable condition and new. The zipper dangle pet fell off and it tore in one corner area. This didn’t happen to the other covers I have, so just follow the care instructions. Smoke free, pet free home. Washed in scent free hypoallergenic detergent. Msrp: 100
