Query: Everything was fine until ...

I was just about to finish putting it together when the top shelf would not fit in the groove of one of the end pieces. I then took it all apart and noticed that the bottom two shelves were thinner than the top shelf (make sense because the top shelf needs to support the baby); however, the top of ONE of the end pieces was cut for a thinner shelf preventing me from putting it together. So given I could not even get it put together due to a manufacturing flaw, I'd have to recommend staying away from this one.
