My 3 cats love this tree. I wish you could switch which side the sisal wrapped pillars are though, since my cats like the top cubby to be facing the couch so they can keep an eye on us but this puts the sisal against the wall. I've just turned it so it's kind of diagonal, which seems to satisfy the cats. 

The cubbies are a little small so if you have huge cats, maybe consider a bigger tree. For small to medium cats, it's great. 

Was easy to assemble and has been approved by all 3 of my kitties.
