FurHaven,s Indoor/Outdoor Deluxe Solid Memory Foam Pet Bed allows your paw-tner to not only rest comfortably indoors, but outdoors, too! Available in two different colors and four sizes, this bed has a polycanvas sleep surface with a water-resistant coating to help protect the inside materials from weather and moisture. The memory-foam is laminated to a base layer of medical-grade polyurethane to contour to your furry friend's figure to help support his joints and muscles, providing him with premium comfort. And since this bed is made without bolsters, it,s easy for older or disabled pets to step onto and get comfortable!
