With a triple layer foam construction, the Sofa Dog Bed by PETMAKER is designed with comfort in mind. This sofa style chew proof dog bed offers a plush memory foam bolster to cushion and support your pet's neck, while a removable microsuede cover is easy to clean and provides smooth softness. The large dog sofa for large dogs also features a 3-inch layer of orthopedic memory foam at its base, plus a 1-inch-thick layer of egg crate style memory foam that helps distribute their weight evenly to limit pressure points. A cooling gel memory foam topper provides additional cushioning and keeps your pet cool as they rest, and a non-skid backing keeps the dog couch stable and secure.
