Based on the somewhat inaccurate description I thought before the first building first "Oh God ...". However, the structure is not a problem quite easily and with common sense. Size when set up and pack size are exactly as I wish it to me: Inside is enough space so that our 10 month old daughter can rumkrabbeln there with their toys. Well enough yet, that mom and dad some upper body in the shade have when it otherwise becomes too hot. Price is very good.
