Vitra's Tabouret N° 307, or "stool number 307", consists of graceful steel legs and a fascinatingly unusual wooden seat, whose ergonomic shape is reminiscent of a traditional tractor seat. Created by French designer, architect and engineer Jean Prouvé, the stool's original design dates back to the 1950s. Almost 70 years later, in 2022, Vitra re-released the stool in shades inspired by Prouvé's original color palette.
