The 100% biodegradable replacement cover for our Superior Steel Raised Dog Bed has been upgraded. The old faithful Hessian Cover will withstand the harshest environments. It is now constructed from higher-grade natural fibres found in the jute plant, making it more durable. This cover has a natural stretch that allows your pet the comfort to nest. If it ever gives too much, some time in the sun will return its shape. The beloved Hessian Cover now comes with VELCRO? tabs for easy fitting and tightening. Simply slide the cover over the frame and adjust the tabs. It?s a breeze to keep clean; a hose down will do the trick.
