Over time, the chair has been adapted to contemporary ergonomic needs, with a slightly raised seat. The leather pad, which was originally attached with strings, is now secured with Velcro for added practicality. The shell is made of molded plywood with a stained beech veneer, while the base features black lacquered steel. In the carver version, the armrests are crafted from solid stained beech. The seat pad is upholstered in black semi-aniline full-grain goatskin leather, with a CM 50 kg/m³ polyurethane foam interior, attached beneath the seat using two Velcro ties. The wraparound pads enhance the overall comfort and support.
With armrests positioned at a height of 25 1/4’’, the Tonneau chair is not only a design masterpiece but also a functional and durable seating solution. It has successfully passed FCBA testing, confirming its suitability for contract use.
