Finding the ideal sitting position is certainly possible with the 1414 series due to a greater range and many adjustment options. The Donati Tension Synchro mechanism, the comfort seat with 10 cm adjustability, the upholstered back and the height, width and depth-adjustable ergonomic armrests provide a lot of comfort during long periods of sitting. The chair is available in a version that is (N)EN 1335 certified. The 1414 NPR also complies with the NPR 1813 standard. This standard is a supplement to the (N)EN 1335 standard and aims to indicate how 'proper sitting' and 'standing responsibly' can be carried out during office work. Thanks to the adjustable dimensions, these office chairs provide good and safe support for approximately 90% of the Dutch working population. These chairs have a greater range of adjustment options and are therefore suitable for different body sizes and for a longer sitting period.
