I am not a handy person, but I was able to put this together easily. It does get heavy so I recommend finding where you want to put it and then put it together. Put it against a wall because if your cat jumps and hangs off the side it can tip over. I put it next to my bed, so my cats sleep on the tree instead of my bed. They sleep on it all day and look out my bedroom window.
One of my cats already barfed on it. A sign of true cat love!
