With the addition of short armrests, this extra-wide version of Danish designer Erik Magnussen's stacking chair also gets an easily movable, weight-distributing sled base. Chairik XL's expanded compression-molded seat offers prime back support without pressure on the spine to suit numerous sitting positions. The polished-chrome tubing base and similarly gleaming aluminum arms aptly complement a variety of seat options in plastic, melamine, woody veneers, lacquer finish or translucent lazure.
