Intended to be used under our Fuzzywumpets outer bed covers, the Old Bones waterproof cover is not a crunchy, crackley, hard plastic cover, but rather a soft, flexible fabric waterproof cover that you can easily wash in your machine.  Made out of a high tech fabric developed for use in hospitals, it slips easily over the mattress ticking of the bed and zippers shut.  Ideal for older or incontinent pets, or just to ensure that your Old Bones bed stays pristine for years to come.
