A 1.2 in thickened base is what keeps 52 in of tower steady when a cat lands hard on the top perch, and the round corners on every board remove the edges that catch fur and skin. Three resting places are offered at different heights: a 16 in condo, a 16 in perch and a 12 in space capsule for a cat that prefers to be enclosed. Plush cushions are removable for washing. Plywood and pine wood construction with paper string posts spans a 24 in base and weighs 34.5 lbs, with 33 lbs allowed on each layer.
