I pain a lot of money for this set and it made of cardboard. Totally not sturdy for a 7 year old.

Our 6 year old loved the first set we got her so much that now as a 7 year old we got this set to expand her building possibilities! She used to need help getting the second story pieces attached, but now she can build solo! So much fun - supports creativity ans imaginative play!

This is definitely fun to build. Adults will have to help unless older children. More fun if you have a place to leave it after it's built. Definitely, fold all the cardboard attachers first and cut all the Velcro. You should try to buy another Velcro roll for a few dollars. The fort is much more stable using the cardboard attachments plus Velcro. My daughter is 6 and can do it herself but still needs a little help. Before I purchased I sized an area to store the cardboard since I couldn't leave the fort up for too long.

This product fits in with the Frozen movies and granddaughter calls it her Frozen Castle. I only ordered the 16 panel igloo and already ordering another for more building options. Loved by my granddaughter and her parents. Granddaughter was playing in it before her dad finished building and wanted to sleep in it that night.

Did not hold their int. Flimsy.
