Full size mattress protector. Purchased from Mattress Firm store with new mattress for my son. We opened the box and put on the new mattress protector when the mattress was delivered. We then discovered the mattress ordered for my son was not the mattress delivered. My son then decided he wanted a queen mattress instead. The mattress protector was immediately put in the box and stored in son's closet. Mattress Firm does not take back mattress protectors once taken out of the box. I do not know if the firmcare warranty applies to a mattress protector purchased and returned by phone to the Mattress Firm store. The mattress protector is 99 percent new! The zipper is absolutely perfect and no stitching flaws. You will get years of quality use from this mattress protector.
