Dieter Rams introduced a reengineered version of one of his lesser known masterpieces - the modular 620 Chair program. It was Rams' second Vitsœ product, arriving two years after the 606 Shelving System made its debut.

Most customers start with a single chair, which arrives flat-packed in cardboard and is assembled using a single tool. When you need more you can order more to make your single seater into a double or triple or more kind of sofa.

The chair's 50th anniversary is this month and Rams worked with Vitsœ to overhaul its components and improve the chair in its entirety.

“We cannot go on continuing to make furniture that no longer fulfills its function and therefore ends up in a hole in the ground," explains a rep from Vitsœ, which has campaigned against planned obsolescence for decades.
