We use only human grade materials for our beds. Our foam lasts up to 3 times longer than standard pet beds. Our covers are super soft, cuddly, and easy to care for. The luxurious sherpa topper is copper infused to naturally control odor and unwanted bacteria. All our beds have a waterproof barrier between the topper and foam to protect the foam from any moisture. CopperPet beds are made for extra comfort but durable to provide a lifetime comfort your best friend. Great for home, office, travel, kennels and more!
