Our SmartKidsPlanet initiative began in 2017 when 3 geeky and dedicated parents saw a gap in the children’s toys and games market. An opportunity was spotted while we struggled to find toys and games for our kids which enriched their minds and guided them toward science, art, math and construction. The trio then knew that their paths were set, establishing an online shop with a comprehensive range of intelligent toys for babies, children and young teenagers.

With offices based in California, our SmartKidsPlanet team enjoys a daily growth in our presence within the children’s educational toys market. We love our new place in life, and we love helping young minds with their growth and skill development, all while having as much fun as possible.

Building Fun

I have a 5, 6, and 12 year old. It was a hit with them all. We bought two boxes and there was enough space in their tent for all three of the kids, plus a bean bag! The tent would not have held up heavy blankets, so sheets are the way to go. I would highly recommend this creative and unique toy!

Kids love this. But buy two sets!

We love it. Husband and I help and enjoy spending time with the kids. Its the one thing that they love more than electronics. I regret not readin reviews and buying two or three sets instead of just one. Ordering another!

Highly Recommend for Tent Builders! They Wil Love!

Gave as a Christmas gift to a 6 year old grandson who loves to build tents with his older (7 year old) brother. Perfect. Their dad worked with them initially, reading/following the instructions, as instructed. Once they caught on, they were good to go and can easily assemble by themselves. Purchased a size-appropriate clear plastic storage box (with lid) for them to store the 69 pieces (with instructions) in. It works perfectly to keep everything collected and stored away when not in use.

Holds blankets just fine, great product.

Holds blankets just fine, great product.After reading reviews on this kit and hearing lots of whiners I was stoked with how awesome this toy is. It holds together just fine and will support blankets and sheets. I did get two kits and love building forts with my five year old and ten year old. After using it once or twice the balls are easy to understand and no longer require instructions. Its fun creating different forts with the boys and spending quality time together. Ill probably get another set sometime so we can go bigger. It would be nice if the sets came with more pieces for the same price, but definitely a good product.

Fantastic but for bigger children I۪d definitely recommend two boxes. Santa brought two boxes of this yesterday and we absolutely love it. My 9 year old is in heaven. I would definitely recommend it. It۪s quite easy to do the simpler structures and the directions for more complicated forts are easy to follow.
