This lump of a foam is an orthopedic bed for older, bigger dogs who need to have a softer sleeping place than a floor mat.  The bed is designed with “railings” for support, preventing the dog from rolling onto the floor. But this may also be removed when needed. Inside this cushion are long strand fiber fillings which do not build up bacteria and potentially harm the dogs. They can stay snug, safe and comfortable.

The surface is slobber resistant too and is designed for easy cleaning, while the bottom has an anti-slip material.
