Both perches lift off - 16.5 x 16.5 in each, one at 5 in deep and one at 4.5 in - so they can be washed or moved to a windowsill while the frame stays put. The open condo at the top measures 19.5 x 19.5 x 9.5 in, a lounging bowl rather than an enclosed box, for cats that want to watch the room. Height reaches 57.5 in on a 23 in round stand, with 33 lbs per shelf and 33 lbs total weight. Faux rabbit fur lines the surfaces and MDF forms the structure, with metal reinforcement at the joints.
