This is a pretty good cat tower.  It has a nice, chunky base, and is definitely sturdy.  The round “bed” thing that had to be screwed on did not sit straight, though.  The screw is actually mounted crooked, so there’s no way to correct the problem.  The cats of course don’t know, and wouldn’t mind if they did!  But I see it, and it looks bad.  But it’s just in the office, so it’s okay.
