easy to assemble, size I wanted, but my cat hates it so far...lol, no matter how many treats I hide in it, she refuses to go near it. When I put her on it, she runs. Oh well, if she doesn't take to it in a few wks I'll donate it to the local cat shelter..its a decent cat tree, could be a bit more sturdy,esp. if you have a bigger cat... just as any, your cat may like it, or not. Theyre picky creatures as any cat owner knows
