Crafted from hand-selected, sustainably sourced oak and carefully assembled by hand in Europe. Every detail reflects our commitment to quality, timeless design and lasting durability.

Built on the staircase principle, KLAPP supports active sitting and natural movement at every stage — eliminating the need for constant adjustments. The fixed steps also allows kids to climb up & down themselves, fostering independence from early on.

Timeless design, exceptional craftsmanship and premium materials. KAOS KLAPP Premium Wood is thoughtfully designed to stand the test of time — growing with your family and made to be passed down from one generation to the next.
Because great design never goes out of style.

“The coolest, most stylish yet practical high chair I’ve ever seen. Such a considered design and that green colourway is just excellent. They’ve just elevated the whole high chair game.”
– Charlotte Kewley, founder of The Little Stylist, @thelittlestylist
