Standard Chair SP by Jean Prouve for Vitra.
Chairs take the most strain on their back legs, where they bear the weight of their user's upper body. Prouvé took this into account very succinctly in Standard Chair. Tubular steel piping is enough for the front legs that take relatively little strain, whereas the back legs are made of voluminous hollow sections and pass the strain on to the floor.
Standard SP (Siege en Plastique) brings the iconic chair up-to-date without changing anything about its form; a seat and backrest of robust plastic in a carefully chosen colour palette gives Standard SP a contemporary look. The plastic parts can be combined in various colours and easily switched out or replaced. To match the plastic surface, the bases feature a resistant, matt powder-coating.
The Vitra original selection offers a 10-year warranty.
