These stools were really nice. We met Chris Jackson in his booth, which was filled with more than a dozen of his Pythagoras Stools. Each stool is made from three pieces of powder coated steel and locks together, aided by super strong 3M industrial tape. You can interchange the colors, but more interestingly, the design recedes as it approaches the floor, giving it a very small footprint and making it much nicer to sit on.
