TriWing is a uniquely shaped chair design created by Marco Hemmerling. In his word’s, “TriWing integrates four different sitting postures in one continuous shape. By flipping the chair along the longitudinal axis the furniture changes its posture and appearance and unfolds its multiple applications. TriWing can be used as dining-chair, lounge-chair, reading-chair or deck-chair. The seat height of the various positions is related to the particular use. The double-curved shape incorporates the ergonomic demands and generates at the same time the necessary stiffness and stability of the chair. Due to the individual weight of the user TriWing adapts slightly in shape and absorbs the impact of the actual forces. The chair aims at a playful use and is produced in a digital workflow from design to production.
