The Foster 500 chair was designed by Sir Norman Foster for Walter Knoll. The clear precision and high quality materials are also evident in other pieces of the Foster series and can be found in many details such as, for example, in the valuable foot frame of the Foster armchair 500. Sleek, elegant and classic in style, clear-cut proportions pronounce the surrounding space. Included in the 500 collection are also the larger versions with loose seat and back cushions.
