I love this cat tree. It was easy to assemble and didn't require any additional tools (instructions specify that two people are needed but I did it myself and as long as you can reach through the pieces one person should be able to assemble it fully in a half hour or so). I love that it's made from a soft velveteen material instead of carpet (not trying to have a cat make judgement calls on which carpet she can and can't scratch) it's sturdy alone and comes with an anchor for added stability. It's shorter than it looks in the image but is true to it's listed measurements. I've already recommended it to several friends.
