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!


Love the pikler triangle and slide! Quick delivery and relatively easy assembly. I got it to use with kids 18 months through 7 years old, and they all love it. I have a mobile gymnastics program, so I pack it up in my car and transport it all over. Love that it folds up. Great quality and super sturdy, awesome customer service, I would recommend to anyone!

Great Pikler!

Very well built and our toddler loves it! I got the rungs unfinished and used milk paint to do a rainbow finish...turned out great. Communication was wonderful and shipping was surprisingly fast. Thanks so much!

Great product.

The product arrived sooner than expected. The assembled product is very well crafted. I can’t speak to assembly because my father, a professional cabinet maker put it together. However, he didn’t complain a lot and said it wasn’t hard. He said the craftsmanship was quite good. It’s very sturdy and I don’t worry about it tipping. My kids are 5 (50lbs) and 2 (25lbs); both use it without problems. I’m glad I got the jumbo, it’s going to be relevant for a while. But if I had less space I think the large would be good too.

My dad built a 60” plank/ladder to go with it and the kids love it. You really need this with a ramp for the full effect. They use it daily as a slide off the triangle. For motor development I think it’s great for my two year old. They use it for building forts too. This, in combo with the Nugget couch, is the ultimate open ended gross motor set up. :)

Thanks for a wonderful product!

Amazing investment!

We received our Pikler triangle well before expected, 2.5 weeks after ordering! Communication on status was great, husband and I easily assembled it with a power drill in about 20 minutes. It’s beautifully built, with not a single rough spot or corner. Our 18 month old is constantly climbing and hanging on it, and enjoys taking her books under it to hang out. Grandma added on the ramp for us, which has kiddo entertained for hours (which I didn’t think was possible). It’s amazing to watch her struggle and overcome, and she’s clearly learning so much about what she’s capable of. The pure joy and satisfaction on her face the first time she mastered walking down the ramp was well worth the money! We expect this to be a staple in our house for years. Thank you RAD!
