Unopened and unused, but please refrain from purchasing if you are concerned about minor details due to home storage. I bought this to let my baby roll around on the floor, but they weren't interested in rolling, so I never had a chance to use it. There is no cover, but why not use your favorite towel or swaddle blanket as a cover? This is the 74x80 size, which is now discontinued? This baby care mat uses soft foam for the inner material and has raised sides and head area. Placing it on a changing table makes diaper changes safe and comfortable for your baby. It's made of harmless plastic, so it can be cleaned by simply wiping it down. VADRA Veadra
