Originally coined “the Levi’s Chair”—Gijs Bakker aimed for comfort akin to an old pair of jeans—his 1972 design was a riposte to the previous generation’s stiffer tastes. GB Lounge features an invitingly stuffed foam seat fixed in a powder-coated steel frame—and the single seater and its companion pouf (also at A+R) can even be transformed from a solo chair into a multiple modular sofa.
