While it may seem that only having a few parts would be easy to put together, it wasn't! It was tough to get some of the pieces to pop together, and the directions could seriously use a re-vamp to help with explaining how to do it. In my opinion the overall material is relatively strong, but after only a couple weeks of use, I can see that one side seems to be slightly caving in...this very much concerns me for the safety of my child!!
