I absolutely love it and so do my 3 adult cats. It came early, it was easy to put together, and it's super sturdy. I got a little confused at times with the instructions, but I was quickly able to figure out where I was going wrong. It is very tall, I had to stand on a chair to finish the top portion. It doesn't wobble and everything was in great condition. It came with a few spare parts as well, which I love.  I'm considering buying another for the cat room in my house.
