Easy to put together, but the quality isn't as good as I expected.  The carpet is thin, actually not even carpet - more like a fur fabric.  There is hardly any padding between the wood and fabric to make it cushy and comfortable for the cats to relax on.  The screw used to put the top tier on the top spindle stripped easily so that tier isn't sturdy - no way for me to fix it on my own since that screw was pre-installed into the spindle.  

With that said, the rest of the tree appears to be sturdy and the cats do like to play it in.  But, they don't sleep or relax in it like I hoped they would have.

If I would have seen this in a store, I wouldn't' have purchased it.  However, since it was shipped to us, it was more inconvenient to un-build, pack away and ship back than it was worth.   For now the cats can enjoy it for as long as it lasts, but I don't expect it to last too long.

Pros: Easy Assembly
Cons: not carpet, not much padding for comfort
