Very easy to assemble.  Quite sturdy and blends nicely with decor so the room doesn’t scream cat.  I really like this as it has a good mix of perches so Princess Fluffybutt doesn’t get bored.  Only thing that I wish it had was a scratch pad on the floor of it.  In the pictures, her highness is sitting in a pet bed that I bought separate.  I included it for height perspective because I really like that I can tuck this behind the sofa
