Husband put it together in about an hour while watching tv - other reviewers seemed to have trouble with assembly but it really was easy.  It's very cute and just the right size for our smallish 18 month old granddaughter - due to the stacked design she will be able to use this for a few years without outgrowing it.  She absolutely loves it!

Pros: Good quality solidly made.  
Cons: The round window is actually a door that opens, as well as the larger square door around the window.  A bit confusing and difficult to open the "window" which makes the unit a bit unstable if it's not attached to a wall.
