The engineer and designer Jean Prouvé produced his creations in his own workshop in Nancy. This enabled him to easily implement customer requests and changes to the products. Numerous variations of Prouvé's most successful designs were therefore developed over the years. This is the case with Chair Standard, which was fabricated in diverse versions for different interior design projects. With one of these variants, the Standard SR (siège rembourré), the chair has an upholstered seat and backrest. The design of Standard SR illustrates the static weight loads at play in a manner that typifies the work of Prouvé: while slim steel tubing is used for the front legs as they bear a relatively light load, the chair's back legs are made of voluminous hollow sections. The lightly padded cushion is carefully integrated into the structure of Standard SR, enhancing the seating comfort. The fabric cover is available in numerous colours and the chair base also comes in a choice of hues. Standard is also available in the classic version with seat and backrest in wood or as the Standard SP model with seat and backrest in robust plastic.
