10. Josef Hoffman Kubus
A classic example of Hoffmann's strict geometrical lines and the quadratic theme in his work is the groundbreaking cubist shape chair known as the Kubus armchair, designed in 1910. This design is definitely timeless and few can match the longevity of the Joseph Hoffman Kubus sofa and armchair. The Kubus is still an incredibly stylish design that could easily pass for a contemporary piece, with a wood frame and foam padding covered by the patchwork-style leather. Hoffmann's Kubus Chair is both a design classic and founding father of the Modernist movement.
