A curved metal arm carries the top perch out over the base, which is why the 18 in woven perch can sit clear of the trunk without the tower leaning. Three tiers make up the design: that cushioned top perch rated 17 lbs, a rotatable 14 in platform at 21.5 in high rated 11 lbs, and an enclosed condo below with a 9 in doorway and 13.5 in of interior height, rated 22 lbs. The whole tower stands 42 in on a 19.5 in round base. At that height it suits an older cat that no longer wants a six-foot climb, and it clears a low ceiling or a sloped attic wall. Sisal rope wraps the post for scratching and two flower-shaped toys dangle within batting reach.
