Designer and cofounder of Established & Sons Sebastian Wrong melds nostalgia and practicality in a stacking version of Heidi. Taking its utility from the classic tractor, the seat is made from vacuum-formed thermoplastic and an injection-moulded resin for a UV-protected finish suitable for outdoor use. The stool also shines in the workplace, with its powder-coated tubular steel frame for a robust construction. Sebastian focuses on comfort and functionality, creating a cantilever base that flexes slightly with natural seated movement to provide a responsive comfort level.
