So much better than I thought it was going to be for the price!  Very sturdy, doesn't rock at all.  The cats were in it as I was trying to assemble it!  The only mistake I saw was that one of the cubbies didn't have the door cut out of the carpeting.  I still give it 5 stars.  I just made an upsidedown "T" slice and they have extra privacy in that cubby.
