    Best gift

    The Fort building kit is the best thing I could have bought for my son's birthday. He loves playing with it, and it's the perfect way to get his mind going and learning new skills. It's been a great tool for developing his creativity, math skills, and problem-solving abilities. I cannot recommend this toy highly enough!

    At last!

    Finally! A Montessori construction kit for kids that is actually fun and engaging. The GROWGO fort building kit just hit the market and it's really advanced for children 3-11 but also has varying levels of complexity for younger builders, so there are lots of other ways to play with this toy too. Really high quality, I wish I had had this when I was a kid.

    holes in joining blocks were too big

    It is very hard to keep any structure together, the holes were two big or ends too small. I soaked the ends and even then, half of them were two big. I would not buy again.

    Loose connections

    This is a beautiful looking fort set, but unfortunately about 3/4 of the poles don’t fit snugly into the blocks, making for a wobbly, frustrating, and potentially dangerous play area. It’s a bummer that a millimeter variance can spoil this otherwise lovely product, but it seems to be the case.

    Great toy

    My daughter loves playing with her fort building kit. She can spend hours playing inside of it and every day she finds new ways to play with it. I also love that this toy is made from natural wood and is a great way to get her outside of the TV.


    With 4 kids at home, we have gone through our fair share of fort building kits. Few have the too high-quality materials to last more than a few days, but this one is definitely an exception. The materials are thick and durable enough to withstand being bashed by my kids, so they never seem to get bored with it.

    Happy parent review
