Vitra Design Museum is temporarily making their "Chair Times" documentary available for free streaming. The film, shot in 2018 by Swizerland's HOOK Film & Kultur Produktion, is presented in German with English subtitles.
"Chair Times" charts a course through an ocean of chairs. In the focus are 125 objects from the Collection of the Vitra Design Museum. Arranged according to their year of production, they illustrate development from 1807 to the very latest designs straight off the 3D printer, forming a timeline to modern seating design.
The trailer--which is really a teaser, if you ask me--is below:
