The HALO seating system comes from the idea of mixing and matching different backrest elements to create a variety of seating configurations, ranging from a single seat easychair, a public seating system, and a three-seat sofa that works well in different environments. The main feature is a very large backrest that can provide additional comfort, but also increases privacy and improves acoustics without the need to close oneself in. The system is called ‘HALO’ because the backrest/headrest is reminiscent of a saint’s halo.
