This FurHaven Quilted Top Convertible Indoor/Outdoor Deluxe Cooling Gel Foam Dog Bed has it all! The pet bed's innovative convertible design features a water-resistant base bed and removable top panel - perfect for outdoor use, dog houses, vehicles, garages, porch, and lanais! The water-resistant base pet bed is manufactured with a coated polycanvas fabric to help protect the filling from weather and moisture. The padded quilted top panel zips on and off to better cater to your pet's preferred form of comfort. Don't need the top panel or just want to wash up real quick? Simply unzip to remove! The top panel also acts as a pocket for cooling or heating pads! The mattress core is topped with a layer of cooling gel infused memory foam that contours to your pet's figure for improved body alignment and joint relief; the base features a medical-grade solid foam core for better support and value. The gel foam boasts cooling properties that reduce the sleep surface temperature by 1 or 2 degrees, wicking heat away from your pet to help keep them cool. Low profile, step-on design for easy access by older or disabled pets.
