Tris Office Seating

project information

  • Tris gets its name from the pivoting upholstered panels of the backrest that move independently form each other to accept varying pressures from the body. Two thin steel frames attach these panels together. The fixed bottom panel receives a single support arm to which it connects to the seat frame. The seat adjustment mechanisms operate using off-the-shelf complex and/or simple synchron systems. The upholstery of the backrest continues on both the front and back giving it a "soft-tech" look.
  • The seat adjustment mechanisms consist of independent spring-loaded lumbar and dorsal back supports. The structure holding the dorsal back supports moves up and down to adjust for lumbar positions and tilts back beyond 20 degrees. The seat slides backward and forward synchronously as the backrest tilts forward and backwards.
