The mattress cover was opened, but not actually used. Bought the wrong size. Needed a full size, boyfriend bought this size, thinking I had a queen, and the fit was too big. I had to buy a full size Purple Mattress Protector, as a condition of the 3 month sleep trial warranty. The cover does not take away from the feel of the Purple mattress grid, or change the feel of the mattress in any other way. It works well with my adjustable base . The mattress cover does not make a crinkly noise when you sleep on it, or feel crinkly under the sheets. This mattress protector would fit any queen size mattress up to 16 inch deep. I am selling this protector because purple will not accept a return on it since I put it on the bed, and since I had to buy a full-size version as well, I’d really like to recoup some of my money from this mattress protector. Feel free to make a reasonable offer if so desired. Boxed item weighs : 2.65lbs Box dimensions : 10.39 x 7.8 x 3.9
