“We bought a Pikler Triangle for our store Two Peas In A Pod Boutique and my children and other people’s children absolutely love it. I definitely recommend these for kids of all ages. My 8 month old all the way to 5 year old play on ours.”

“We're big fans of our Pikler triangle! We ordered one for my 15 month old son, and it is fascinating to watch him discover new ways to use it. From crawling under it to climbing up the rungs to sliding down the ramp, Rufus loves it! My husband is a rock climber and he was so excited about the climbing holds on one side of the ramp. It's very well made and worth every penny as I'm sure it will be a favorite plaything for years to come!”

About Arch + Mo

Arch + Mo was founded in 2018 in Austin, Texas. Founder and stay-at-home-mom of two (and one on the way!) Lindsey Jensen, was constantly trying to brainstorm ways to keep her young toddler boys engaged and out of trouble whilst playing inside.

A big fan and proponent of RIE philosophies, she set up a “yes” space for her boys, but quickly realized there was something missing. Looking for a way to stay active and exert energy without having to always go outside (it’s hot in Texas, y’all), she discovered Pikler triangles.

After building one for her boys, she realized this was a product that should be shared with the world, and thus, Arch + Mo was born. A native Austinite, Lindsey is a mother to Archer and Milo, a wife to software developer and entrepreneur Orion, and a pet mom to Goldendoodle Banjo and fat cat Sammy.
