I really like the look of this piece. It was easy to put together, and everything fits together very well. My cat likes it. The only downside is that the base is not wide enough to provide the necessary stability for a tree this tall. It's especially bad if your cat is on the larger side (as mine is). I solved the problem by adding some weight to the base. It still wobbles when she jumps down, but it won't tip over. I'm going to permanently fix it by buying a wider piece of wood to mount the whole thing on.
All in all, a good, easy-to-assemble piece that is more suited for smaller, or lighter cats, or someone who is able to do a bit of handy-work.
