Vitra’s Standard SP is a plastic version of Jean Prouvé's iconic Standard Chair. Designed in 1934, Standard Chair has a unique metal structure inspired by Prouvé’s engineering background. Because most of the weight is carried by the chair’s back legs, Prouvé decided to place large, hollow steel legs on the back and slim ones on the front. The grayish blue hue of the Standard SP chair's frame is part of Jean Prouvé’s original color chart, which he developed himself, and it is called Bleu Dynastie. With its pleasantly shaped seat and backrest in durable plastic, the Standard SP (Siège en Plastique) makes an excellent dining chair, and its design matches perfectly with Vitra's EM Table, which was also designed by Prouvé.
