Engelbrechts finesses an extra-wide option with its Chairik XL series and pairs it with a 5-star swivel base, double-wheel casters and height adjustment. Danish designer Erik Magnussen's expanded compression-molded seating offers prime back support without pressure on the spine that comfortably adapts to nearly any sitting position. To go with the polished-aluminum frame, the seat numbers choices in plastic, melamine, varied veneers, lacquer hues or translucent lazure.
