The FurHaven Berber and Suede Blanket Top Cooling Gel Mattress Dog Bed is designed for dogs and cats that love to burrow and snuggle! Featuring an attached oversized blanket top, the pet bed provides a warm and cozy lounging space for pets that love to curl up under the covers. Cuddly-soft berber fleece lines the blanket interior and main sleep surface, creating a super cozy environment for snoozing pups. 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. Easy to clean.
