Add comfort and function to your Chillz Gel Mat. The Chillz Mat Cover is designed to protect the pad against dirt and your pet's paws. Many dogs burrow before they lie down and this cover will help reduce scratches on the mat. It will also keep the mat clean and our covers are machine washable. Don't worry - the cover will not affect the performance of the cooling mat! It's specially designed to be soft and comfortable but still allow your pet's weight to activate the gel inside and cool down your pet.
