This is the larger version of our Foldable Climbing Triangle.  For something slightly smaller, check out our Small Foldable Climbing Triangle.  Or for something even bigger, check out our Jumbo Foldable Climbing Triangle.

Inspired by the design by Emmi Pikler, our Foldable Climbing Triangle is one of the most versatile and thus one of the most useful items for developing motor skills in our line of play structures. It gives children a chance to develop all sorts of skills appropriate for their age. Climbing on the bars gives them sense of place of their body in space where they have an opportunity to test, retest and perfect their climbing abilities using all their limbs and body.

The add-on climbing ramp is especially interesting to them. They have the choice to adjust the climbing angle depending on their ability and courage, as well as to choose the side with ladder rungs or flip it over for a smooth slide. Variations are many, suitable for beginner athletes as well as advanced ones and everyone in between.

Choose between two ramp options: Short or Long. 

The Short Ramp (12"x46") is great for the smaller play space or home. It's more compact for easier storage and transportation. As a slide, it's suggested to keep it at a lower height than the Long Ramp for an adequate slope.

The Long Ramp (12"x58") Is our most popular option. This is best for schools, child centers or for the dedicated play room in your home. It allows for a proper slope to use the slide all the way from the top rung of our Pikler Triangle.

Given children’s imagination, the climbing structure and the ramp can have many uses originally not designed for, like a house.  Just throw a sheet over it, make a barrier between one part of the room and another, tunnel and a passage to somewhere else.  Or place one side of the Ramp on the Triangle and the other side on one of our Stools or Play Frames to create a balance beam.

Folds up for storage and easy transportation

Includes lock knob to keep Triangle from closing

We love this neutral, great-looking pikler triangle! Customer service was also super friendly and helpful.


100% worth every penny. This Pikler triangle is handmade and the quality is outstanding! I’ve seen my toddler more confident with new uneven surfaces and he has better body awareness.

Excellent customer service and product quality

I procrastinated for my two year old’s birthday, and finally contacted RAD. Not only did they provide awesome customer service, my purchase arrived within their estimated shipping window, the instructions were easy enough for me to build after 4hrs of sleep (thanks kiddo), and he and his friends LOVED the set up. Thank you RAD!


This pikler triangle is prefect! Exactly as described, shipping was right on time. Assembly took a little bit of time and effort but we got it figured out and it’s great.


My three boys are ages 5, 3 and 1, and they love this thing. It gets used daily. Great craftsmanship and excellent customer service. I ordered the slide with the triangle, and it’s a favorite as well.
