A 1954 chair reissued in 2023

Knoll's design-plan page dates the Model 31 Lounge Chair to 1954 and says that Knoll reissued it with the Model 33 Sofa in late 2023. The page describes the chair as having a light visual footprint, with a supportive sit and a casual posture.

Scale and upholstery

The page says the chair can be scaled up or down as an organization's needs evolve, and that its rectilinear cushions lend themselves to different upholstery, from woven fabrics to leather and vinyl.
