Go Pet Club's high density 4" Orthopedic memory foam beds will keep your pets off your bed, for good. Our pet beds will not flatten overtime, as it is made of true solid 100% memory foam, not mixed or layered memory foam like many others. The Orthopedic memory foam will relieve your pet's aches and pains in their joints; it is great for pets with arthritis, hip dysplasia and joint and muscle stiffness. All of our memory foam beds come with two layers of protective surfaces: the bottom layer protects the memory foam with a waterproof cover; the second topmost layer is made of real suede, both of which are easily removable for cleaning and maintenance. After removing the pet bed from its package, please allow up to 24 hours for the memory foam to resume to its original shape by laying it on a flat surface.
