This 33.2" X 21.2" X 4" sized crate bed fits perfectly inside the raised lip of the plastic tray in a standard 36" x 24" medium crate. Uniquely Engineered Comfort: Leveraging our expertise in foam engineering, we've designed an orthopedic crate bed that stands out. This specialized construction provides deep cushioning for your dog's elbows, hips, and pressure points, offering relief from the rigidity of metal and plastic crate surfaces. 10 Year Warranty: Our orthopedic crate beds feature top-quality American-made therapeutic foam, setting the standard for excellence in canine comfort. Our beds will retain at least 90% of their shape for at least 10 years, providing optimal support tailored to the pressure curves of your dog. Made in the USA: Handmade by experienced craftsmen and craftswomen in our small Pennsylvania workshop. We only ever use American-made foam to allow us to protect you with our "Can't flatten, Won't flatten" warranty. Easy to Clean: Our machine washable crate bed cover is easy to remove, water resistant, and can be washed without shrinking.
