This item is new and unused, with the inner bag unopened. It's for all dog and cat breeds, allowing even large dogs to sleep comfortably. Size: 100cm x 100cm, 6cm thick. Made with high-resilience fiber that distributes body pressure, making it easy to turn over and get up. It also has good breathability. Comes with a waterproof mat. Since it's a set of 2, you can set them up in different places. Due to the size, the mat will be rolled up for shipping. Thank you for your understanding.
