I purchased this set for my nephew and had a couple of issues. 
1) We were shorted one screw and had to go to the local hardware store to complete the set.
2) The holes on the chairs did not line up with the leg holes. Because of this the chairs are a little uneven and wobbly. It was really difficult to get the screws in b/c of this malfunction.

The plus side - he loves it and it's adorable! Just wish the chairs were more stable and it wasn't so difficult to put together. The reviews said it was really quick to put together, but it was not.
