Great for kids to use their imagination
All the kids loved it and immediately started building forts. Pretty durable and holds the blankets up very well. They did not need any help it was very easy to use. They have already used their imagination to build lots of different types of forts since Christmas.

Buy several!
I bought 2 sets for my great nephew. He loved them (at age 5) and made a huge fort with them. These are also great for creating abstract sculptures.

It's for blanket forts, not stick sculptures.
The elaborate geometry seen in the pictures is not necessary for a simple blanket fort. I use it as a roof between the couch and coffee table, which is wonderfully sturdy. However, they greatly overdo it with all the flexible connectors, which are impractical and useless most of the time.

Fun to build and to play in
This was a great Christmas present for our grandsons. They are having fun building the forts and playing in them afterwards. Mom and Dad like how compact this is when not assembled. Some variations and diagrams on what can be built with the included parts would be a nice-to-have.

Great gift for ANY kid of any age.
My kids love making forts…. But it always involves draping blankets and sheets over the dining room table and it just becomes a disaster. We got this kit for our five year old for his birthday. His nine year old brother also loves it. We got the package with the most pieces- and if you’re debating on which kit to get, get the big kit! My five year old does need my assistance in setting it up- but once it’s up (and it’s easy to do) he’s just fine! If I had one suggestion for Nat Geo though ! If their website had an option to purchase additional pieces! I mean I know I can buy another kit right? But it would be nice if we could buy like a ten pack of the clips….or a ten pack of the green joints…. It really is so fun though!

Disappointing Purchase- Terrible product
I got the 135-piece set as a Santa gift for our 7-year-old daughter, and I’ve regretted it ever since. My daughter has cut her finger twice while using it, and the structure is very unstable. She managed to build the only fort that fits her size, but it’s poorly designed. If you follow the ideas in the instructions, the structures are so small that they’re only suitable for a 2-year-old. I wish I could return it, but my daughter accidentally tore a piece of the box when opening it. Save your money and avoid this product!

NO era para mi, pero al Dueño le facino
Personalmente no probe el producto, por que era para la hija de una amiga, solo hice el puente de comprarlo. Su comentario fue que la niña no para de jugar con su castillo, se inventa juegos y le pone sabana encima diciendo que es su guarida secreta. Como no se realmente como es el producto y como no tuve mala reseña departe de mi amiga, le doy 5⭐⭐⭐⭐⭐ en todo. Lo malo fue la llegada, lo compre el 2 de diciembre y casi lo entregan despues del 24 de diciembre. Concejo en diciembre no comprar si lo piensas tener para el 24 ya que es una ruleta que te llegue a tiempo, por lo menos a colombia. Comprar con mucha anticipacion

More of a Hassle than Fun
My kids love forts, but it’s easier and cheaper to build them the old fashioned way. This kit is as described, but the forts are a pain to put together and take apart. My kids are 3 and 7 and even my 7 year old can’t make the larger ones by himself. And it’s a pain to clean up all the pieces. For the price, I would not recommend for younger children.

Great product
My kids love it. The box is very nice and all parts have a good built quality. I wish there were more connectors in the box still we were able to built a big cubby house.
