Thank you for viewing. Simply layering this on top of your current bedding allows you to easily experience a higher level of sleeping comfort. It's thin, so you can not only fold it, but also roll it up for storage. Even if it gets dirty, you can rest assured. Both the cover and the air fiber inside can be washed for cleanliness. I purchased this last year and used it for six months. I used a sheet on top of the airweave. I am selling it because I purchased something else. As it is a mattress pad, there is no warranty. There are some areas with loose threads, but there is no problem with use. The cover will be washed and shipped. Please check for any concerns. It will be shipped folded. Instant purchase is welcome. No returns accepted.
