Unique bumper-style crate mat of Slumber Pet™ Sherpa Beds combines thick sherpa and bumper-style cushioning. Bed dimensions are slightly larger than ProSelect® Crate dimensions so the bumpers are supported by the crate, softening crate’s edges and providing an inviting nestling area for dogs. High-quality sherpa stays cool in the summer, holds heat in the winter, and is completely machine washable. Sized to fit most crates. Bumper is 2".
