With SIM, Jasper Morrison has created the perfect expression of the chair type inaugurated by David Rowland’s famed 40/4 chair in the 1960s. SIM is a successful synthesis of clear design and distinct comfort: the sledge base in chrome-plated steel wire gives the entire chair a subtle degree of movement. This flexibility, paired with the generously proportioned seat and back shells in supple plastic, ensures a superb sitting experience. Up to ten SIM chairs can be stacked vertically.
