Dynaflex ergonomics


Quality features as standard

Adjusting your chair to suit your body is essential to healthy seating posture. Haworth's seating ranges offer a range of ergonomic benefits that are considered as standard at our level of expertise. Haworth's design DNA draws on our global design perspective and 45 years of technical experience.

Haworth has always put effort into the designing of products which serve the person – especially in the office world. A design which is not meant to fulfil its own purpose, but which serves as an invitation for co-operation between a person and their physical surroundings.

Asymmetric Lumbar Support 

Lumbar support corrects the position of the spine and straightens the pelvis to improve posture.

Haworth, in association with the University of Michigan, undertook a study into the ideal settings for back support in office seating. Scientific research proved that 70% of users prefer asymmetric settings on their lumbar support. The function has been successfully implemented in Haworth chairs since 2004.

Dynaflex incorporates the asymmetric lumbar support in the Flex back model, allowing users adjust the lumbar support vertically and apply greater pressure independently on the left or right of their lower back.


Automatic Weight Control

The Dynaflex seat incorporates a weight sensor that automatically adjusts the pressure required to lean back in the chair. This means that hot desking users can choose a seat and trust that the torsion adapts to their requirements.

Comforto 59 was Haworth's first chair to introduce an automated system to weigh and measure the user to set the torsion of the backrest. This system has been improved on Dynaflex using the latest anthropometric data.

The range caters for a wide range of body sizes while offering the ability to fine tune the settings to the user's preference with the comfort adjustment, pictured.
