Feline Furniture Thermal Pet Mat Soft comfy pet mat radiates heat back to the pet. Large enough for 4 cats to snuggle up on or perfect for a Medium Labrador We hate crunchy pet mats and your pet will too. That is why we went to the extra effort to sandwich 2 sided radiant barrier material between two 3/4 inch layers of loft material so when your cat or dog goes to lie on this it is fluffy, not crunchy and warm. Other companies give you a thin pad, we splurged on your pet. Zipper allows you to remove inner material and wash outer cover. machine wash hand dry cover. O.k. To hand wash and line dry inner material if it gets soiled. Then roll up put inside cover and grab corners and flip it into place. Just like putting grandmas down comforter together. To re fluff inner material put in dryer on low heat for 1 minute at a time. Ready to use. Take out of box, unrolls by iteself and use. Your pets will love it.
