Oh my god the assembly instructions are terrible. I mean super duper awful. It's not that the language is difficult to understand. The point is, they are completely wrong. If you put it together as a written guide or as a diagram, it's practically useless. My suggestion is to try following the schematic and then test your engineering skills by rearranging the pieces to get it reasonably correct. In the end we used the smallest parts below, 2 small parts connected to the connector. We then used medium sized pieces for the sloping roof. However, I had to cut off one of the small pieces at the bottom by about 10cm, otherwise there was too much tension and the fabric would tear. Now that everything is ready, our daughter loves it. Just expect to use your McGuiver skills to put this thing together.
