Poul Kjaerholm’s Pk22 lounge chair is a classic in the design world, made of spring steel legs, crossbars, and side frames attached with machine screws and covered in canvas, leather, or cane. Poul Kjaerholm was a Danish designer known for his PK22 chair, which was awarded the Grand Prize at the Milan Triennale in 1957 and 1960.
Bentwood furniture was not invented by Michael Thonet (1798-1871), but he perfected a method for mass production. In 1819, in Boppard, Germany, he opened his cabinetmaking business, and by 1840 he had invented the steam-softening technique for bending rods of hardwood into flowing yet structurally solid shapes. There are just six sections and screws in his all-time classic, Model No.14.
Josef Hoffmann’s Sitzmaschine armchair, introduced in 1905, is a symbol of modernity that blends functionality and design. The chair’s aesthetic, built in collaboration with J. & J. Kohn, is pioneer in bentwood furniture, showcasing Jugendstil’s geometric principles. The design represents an evolution in adjustable furniture, combining innovative materials with artful architecture.
He simplified the chair’s structure so that the sculpted backrest and arms form one continuous element. The turned legs rigidly support the deep seat rail and top piece without the need for stretchers, combining an expressive form that draws on Chinese precedents with natural materials and a rationally conceived design destined for the most exacting factory manufacture.
