So this cat tree looks really cool once put together, but my cats aren't into it.  It takes some time to assemble, but it's not difficult.  Unfortunately, I think my cats are set in their ways, and they aren't using it much.  I feel like the size of the cubby holes are meant for smaller cats, also (I have one smaller cat, 2 years old, and one larger 16lb cat).  The material is super soft feeling, but it's solid wood right beneath, so not a lot of cushion.  I wish I would have bought one of those simpler carpeted trees instead...
