Unlike bulky cat beds that can take up valuable floor space, this over-the-door apparatus provides an out-of-the-way area for felines to rest. Each of its three 27" W x 13" D levels is lined with a sisal scratching mat and an entrance/exit hole on the bottom. It hangs from the top of most doors with a pair of metal hooks yet can also be used as a free-standing catwalk with a pair of 20" L legs. Crafted from durable MDF, it supports up to 60 lbs. (20 lbs. per platform) and has a polished espresso finish. Assembly required. 46 1/2" H x 27 1/2" W x 13" D. (35 lbs.)
