I am quite pleased with this cat tree.  Fabric is a little thin. I wish the little house was fabric covered inside but that is not a big issue.  Both of my 5 month old kittens love it and use the sisal posts to scratch their claws.  Also play chase to the top to see who wins.
I plan to move it closer to a window soon.  The base size is good and stays stable but then my babies are only just over 5 each.
My tree did not have the hanging toy as seen in the picture.  Seems like a good deal for the price. Not a 5 star due to thin fabric and the fact that the sisal wrapping is not full length on the posts.  Please keep a picture available when you put it together.  The instructions are very schematic and the picture keeps you on track.
