For Aspiring Athletes


Our largest climbing product is the Jumbo Foldable Climbing Triangle. This form of triangle, which was inspired by child development pioneer Emmi Pikler, is one of our most versatile items. Not only is it a lot of fun to use, but it promotes gross motor development and confidence building. It encourages free movement and imagination.

One of the most popular items in our gross motor development collection, especially when used in conjunction with the RAD Climbing Ramp, Hengstenberg Ladder or DeskEasel, which may be ordered separately or as a bundle.

Although our products are crafted to encourage exploration and free-form play, please never leave your child unattended to avoid injury.

We opted for local pickup and the RAD team is top notch! My kids love it and it was a fantastic Christmas gift.

More than a climber!

I purchased this jumbo climbing triangle for my 3 year old’s birthday last June during the pandemic, and it has been so great. He plays every day just hanging out or leaning on it or sitting on top of it to play. I love how big and tall this is comparing to other products especially for my toddler who is very active. Also i got the ramp too and it was easy to clean. My boy drew all over with his markers and all wiped clean easily. Thank you for an amazing product.

Absolutely the best!

We are all in love with these furnitures from the books, pikler triangle and tables and stools. We cannot have enough of it. Thank you.

Delightful! Great service, great quality, easy to fold

Well made construction, arrived quickly, made in USA by craftsmen? What more could you want! Our son loves playing on the slide, and can practice over and over in our living room, his gross motor skills are getting more and more refined (we purchased jumbo size). Much easier to fold up and store along the wall than I expected. Our living room is tiny and this was my biggest reservation. Assembly was straightforward and well explained. So happy I stopped dreaming and just bought it!
