Grounded in extensive ergonomic research, Fern’s design puts the person at the centre with ergonomic innovations that provide total back support, edgeless comfort, and free movement. The result is a next-generation sitting experience that is distinctively responsive to each person. The chair works with you, not against you so you can sit better, work better, and feel better in today’s changing workplace.
