Great for protecting my beds soft , quiet , and easy to clean
Color: Grey, Size: Queen (Pack of 1), Color: Grey, Size: Queen (Pack of 1)
I had to purchase since a family member had surgery and wanted to protect the mattress. It is a sleep number and this waterproof cover fit good and I like that it is not noisy. I am considering purchasing for the other beds in my house because I like it so much. It is soft and quiet and waterproof, Good product. I like the different colors available.

Conforms well
Color: White, Size: Queen (Pack of 1)
Have had for a while and holding up well on the bed. Conforms to the mattress very well. They compress it into a small bag with all the air out of it when you get it then when you pop the bag open everything starts to expand. After being on the bed for a day looked like a regular mattress pad. Have not had any wetness on it to see how it holds up there but very good for the price.
