Ours disintegrated after a long decade. I washed ours on a monthly basis. Found another at Bed BAth and Beyond by Stearns and Foster. It's quite comfortable and waterproof. I believe we paid $99 for the queen. I washed it before putting it on the bed and it was no more trouble than the other one. A 400 thread count. the case it comes in is zippered and can be used for other storage.
