Great vintage piece, designed with ergonomics in mind by Swiss company 'BEMAG' (based in Sissach). BMAG was founded in 1899, and has produced a number of chairs for Swiss schools.
The seat can be easily adjusted up and down.
This chair is in vintage condition, so the usual nicks, dents and scratches and discolourations that accumulate with time, which give this high quality chair a nice character.
