Mattress pad
Very nice! I worked in a bedding store, our waterproof mattress covers, same caliber, were $149 and that was 10 years ago. Would order 2 more, queen size this time for other beds.

Plush.
The product is describes
as Ultra Plush. It has no body at all. It does have the plastic barrier, and is very thin. I hope it does not tear during normal body movement while sleeping.
