Tan-Sad "Doe Meer" (Do More) Chair
work, office, laboratory, factory machine operator stool
swivel, height adjustable, back multi-adjustable
base of tube steel
these were some of the first chairs to be designed with the goal of higher worker productivity
made in England by Tan-Sad and sold in the Netherlands by Ahrend
the plywood seat and back are not original, my guess is that they were replaced around 15 years ago
industrial, vintage, retro
30s, 1930s, thirties
