Stacking chair with and without armrests by Prof. Matthias Rexforth which is remarkable for its plain design and the exceptional comfort of its ergonomically shaped plastic shell. Due to its simple shape and its basic elegance there are many opportunities of use. Its shapely base structure underlines the floaring character of the flexible seat shell. Different colours allow for diverse variations in the design. The sophisticated shape of the shell which is refl ected in its high class plastic makes the UNICUS unique. The different surface structures on its front and back allow for a symbiosis of comfortable seating and timeless elegance.
