The task chair redefined.

Trinetic delivers progress in motion. Three independent pivot points combining to achieve the most sophisticated kinetic yet.

Trinetic is the world’s first fully certified task chair to provide dynamic support without the need for manual user adjustments.

Trinetic does not need to be adjusted for individual users, making it the perfect chair to support flexible work patterns in situations where several different people can be sat on the same chair throughout the course of a working week.


The next generation.



The chair that works with you.




Intuitive control.

Trinetic is an intuitive product that delivers controlled support through a wide range of movements. Three independent pivot points collaborating with a flexible seat and backrest to cradle the user in an ergonomically-sound position without the need for manual intervention.

Trinetic is designed to support, rather than resist the user – following the individual through the thousands of micro-movements that we all make across every hour of every day to provide tangible circulatory benefits.

Trinetic is the next generation of task seating.


Levent Caglar

Head of Ergonomics at FIRA

“Over the last two years Boss Design have completely deconstructed our established ideas about how an office chair should move and what it should offer the user, before creating a product that shows tangible improvements. The result is not only relevant for today’s flexible working patterns, but also offers the user a level of comfort and support that will be the envy of its peers.

When Boss first presented me with their idea in 2013 I immediately shared their enthusiasm for the concept and saw the opportunity for this product. Since then, myself and the rest of the ergonomics team here at FIRA have helped them to prove and refine the concept in order to ensure that the end result was the best it could be from an ergonomic perspective. We believe that Trinetic moves the user experience forward and sets the benchmark for the next generation of office task chairs”.
