My nephew had so much fun building a fort. I liked that when disassembled it's very easy to store.
My kids aren't using all the dining room chairs to build forts anymore, YAY. My 8yo son loves this and hasn't stopped playing with it for two days straight, and even my 12yo daughter joined in. The forms stay together well, even under sheets and blankets.
This make-a-fort kit had adults and kids on the floor working out the geometry and even the 4-year-old could pop the rods into the connectors. On went a sheet and she loved her fort; us grown-ups loved how a kid can dismantle and put it all back in the box to shove under the couch until next playtime. Only wish there were more connectors; I may just buy a second set.
