Brigitte Mah Suter sells hand-made wooden toys and play structures for kids on etsy. "We are so excited to announce that we now sell Pikler triangles! After months of R&D work and many dissatisfied attempts, we finally nailed it and created a triangle that is modern in design, strong in structure, and fun for little ones. Our kiddos have been climbing on it non-stop and we've even convinced conservative grandma that it's ok to have in the house. If you've never experienced a Pikler triangle, it is a climbing structure that precedes playground climbing equipment. It's meant for littles as young as 6 months (or whenever they are sitting and starting to reach upward) and as old as preschoolers - though it's very difficult for some of the older kids to resist climbing; it's so instinctive to move upward."
