The cat tree came in the time frame Wayfair estimated, and was packaged well.  The material the box/platforms are made of are pretty cheap composite - the box part feels like it could crack if you put too much direct weight on it.  
If you have bigger cats, I would recommend a more heavy duty cat tree.  This one wobbles when my cat (who is really light) jumps on it.  But so far she likes it.
But it's really, really easy to put together, so that's a plus!
