The 15cm thickened cushion uses high-strength 26D sponge, which is perfectly raised, widens the dog's field of vision, and improves the pet's sense of security. The raised three-dimensional edges and the built-in safety belt can keep the dog in a safe and controllable position for interference-free driving. The zipper design of the dog car seat and cushion makes it easy to detach and wash daily. Take out the sponge and the removable cover is machine washable. The sponge cannot be washed. The sponge is vacuum packaged. Please wait 24h for it to recover its shape before using it. The size of the puppy car seat is L50xW50xH40cm. It's suitable for small dogs weighing less than 13kg. Not only use as a dog bed indoor on a daily basis, but also as the car seat for dogs while travel happily with your pet.
