Foldable Climbing Triangle (Large)

Ships in 2-3 Days


Our large Foldable Climbing Triangle is our most popular climbing product, used by children everywhere. Inspired by child development pioneer Emmi Pikler, the Climbing Triangle is one of the most versatile products in our inventory. Not only is is a lot of fun, it promotes gross motor skills as your child masters spatial reasoning, balance and a wide range of gross and fine motor skills, appropriate to their quickly evolving skills. The Climbing Triangle encourages a sense of body in space, encourages free movement and imagination.

Although the Climbing Triangle may look like a simple climbing frame, it is a lot more than that. Older infants can use it pull themselves up as they prepare to take their first steps. Toddlers can use it to navigate climbing up and over and use it to build forts or other imaginative play. The ramp/slide can be used as a toy boat, truck, car and toy ramp or slide. The possibilities are endless!

The RAD Reversible Climbing Ramp or Hengstenberg Ladder can be purchased separately or add-ons now as a bundle.

My daughter loves it!

Got the large Pikler triangle as a holiday gift for my 16-month-old daughter. She loves it!! Had a little trouble assembling it, but the Rad team was readily available on a weekend to offer support. The foldable feature is very helpful as we live in an apartment. Highly recommend!!!

Love our Pikler Triangle!

Great company! They were really fast and had great customer service. Our triangle and ramp are so well constructed and really a great addition to our playroom! I can’t recommend them enough.

Better that we could have dreamed!

From the moment we spoke to Radomir, we knew we were in good hands! He went above and beyond to meet our needs and make our family happy! The triangle itself is beautiful, superb quality and being enjoyed everyday by our youngster.


Super straightforward to assemble and high quality, solid-feeling wood. The kids are big fans!!

So worth it!

The large pikler triangle with the long ramp is so worth it! It is amazing quality, so smooth, very sturdy and was easy to put together by myself. My favorite feature is that I can fold it and put it away. The large is the perfect height for my almost 3 year old son. My son loves it and has played on it everyday since I bought it 2 weeks ago. Since playgrounds are still closed where I live I felt this was the perfect substitute for my son’s need to climb, slide and jump safely in the house. I wanted something versatile too so this was the best choice. There’s so many other activities and ideas you can do with it. The quality feels it will definitely last for years which is great since I plan to have another baby soon.
