The zippered outer cover of the Original Bed combines water-resistant 420 denier nylon packcloth with a polyester fleece or faux suede sleeping surface. This outer cover surrounds an inner cushion made of ripstop nylon. The inner cushion is filled with recycled fleece scraps which will not break down as quickly as the filing used in most other beds. The inner cushion is odor and water-resistant, but if necessary, the inner cushion can be unzipped to remove and wash the fleece filling. Of course, the outer cover and inner cushion are washable as well.

These design features extend the life of the bed, allowing a pet owner to simply replace the outer cover when needed instead of discarding the entire bed. Outer covers can be purchased separately for replacement or for a new look.
