Dutch Practice Directive NPR 1813

In Germany the office swivel chair must comply with the DIN EN 1335 standard as far as height, depth and seat and backrest adjustability is concerned. With the stipulated values, an office chair fits people who are between 1.51 m and 1.92 m tall. In the age of globalisation and mixture of ethnic groups all over the world, the population is increasingly diversifying regarding body height and size.


In the Netherlands it has already been recognised that there is no longer an average Dutch person. Therefore the Dutch practice guideline NPR 1813 sets higher standards regarding the adjustability of the swivel chair and requires adjustment options way beyond the DIN EN 1335 standard.
