Arm's Reach Co-Sleeper Duplex Gray Dog Bunk BedSpecially designed pet bed built for co-sleeping. The Arm's Reach Co-Sleeper (R) Duplex Gray Pet Bunk (TM) Bed is a separate sleeping area designed especially for your "4 legged friends". It provides a comfortable separate area that's within reach, allowing you more sleeping space. The unique bunk bed design allows one pet to sleep on top and one to sleep on bottom. It's like having an extension of your own bed, without actually having your pets in it. The bunk bed includes two plush pillow pads with removable machine washable covers. The lower bunk offers access from three sides. Constructed with a strong metal frame and durable polyester/nylon fabric. The top bunk can also be used as a grooming surface.
