Champ is a stacking stool intended to fit effortlessly into a home, café, or office. The use of broad steel tube gives it a pleasantly robust familiarity. Named with a nod to its similarity to a champagne cage, Champ is a stool that finds function in its casual and practical nature.

The simple form is made possible by expert tube bending and brazing (performed at first by bicycle welders that Matter commissioned for the initial production run) allowing for infinite stacking without exaggerated proportions. The diameter also makes for easy grabbing, and allows one to stack it without difficulty.

Since its initial debut as a low stool, the Champ collection has grown to include a table, as well as counter and bar stools. In 2022, the Champ stool was included in the objects collection of the Italian fashion label Sunnei.
