PAWZ Road 5-Level Cat Tree Cactus Style Floor to Ceiling Tower for Indoor Small Cats, Gray

Giving this 5 stars because it's great quality, easy to assemble, and stable. I chose this tree with a spring-tension top rod instead of one with a screw-on one because I thought it would work better with my slanted ceiling (it works great!). However, the platforms are kind of small for my cat (and she's only 10 pounds). It would definitely be better suited for a kitten. I had to fan out the shelves because she couldn't get up or down different levels when they were straight. I have another PAWZ tree with larger platforms and she has no trouble getting around that one. But overall this is a great back-up tree that gets used quite a bit, she just doesn't have room to take naps on it. :)

This assembled easily. All parts marked ... they may look alike, but they are not, and the letters on the parts clear up the assembly. I put it in my office so the cat or cats can climb up and observe without walking over my laptop. I got the tallest version. It did not quite reach the ceiling, but ... using empty tubes that I could fit over the top pressure levelers, I could get the extra 4" for my ceiling. There is stiff foam to fill the gap, and the carpet tube covers manage to cover it all with a zip tie to hold it in place at the bottom. It is stable.
