Replacement cover for Furhaven Deluxe Mat Water-Resistant Indoor/Outdoor Polycanvas Traditional Foam Mattress Pet Dog Bed. Cover will fit all bed styles - orthopedic, pillow, memory, and cooling gel! You can also use you own stuffing, such as styrofoam beads, buckwheat hulls, old towels, pillows, and others. Also consider using your old clothes! Pets will find it easier to acclimate with their new bed as they find comfort in their owner's scent. Use whatever works best for you and your pet.
