At 19.5 in this is a cat tree for a bedside table or the corner of a small flat, not a floor-to-ceiling structure - and the wide 18.5 x 13 in base keeps it from tipping despite the low profile. A bottom condo gives privacy underneath while the padded top perch takes up the whole upper surface for lounging. Each tier supports 22 lbs. Wear-resistant sisal posts handle claw maintenance. The tree weighs 9 lbs, so it can be carried to wherever the sun is falling. Plush fabric over engineered wood; assembly required.
