This comfortable pet bed is the best of both worlds. The base is made from orthopedic foam with a dreamy, polyester fluffy filled pillow top. The bolsters just add more comfort and chin support for the pets that like to hang their heads on an elevated spot. The bed has zippers for both the base and the bolsters so it can be broken down and machine washed. Binding on the bolsters adds a bit of class to this heavenly bed. One year limited warranty.
