This is a stylish, top-of-the-range chair with a technical design. Its innovative concept and integrated hinges give it a very sleek look and it can be finished in many different ways.

Available in several different versions, this chair is suitable for the following uses:

  • (FDG) Chair with hinged seat folding down flat forwards for retractable seating systems.
  • (F) Fixed chair for balconies.
  • (D) Beam-mounted moveable seats.

When the chair is opened, the backrest rises by 12 cm for the very highest level of comfort. It is fitted with armrests which lift automatically when the seat base is lifted.

The gas-assisted operation and its automatic folding and unfolding function (coordinated with the movements of the tiered seating) mean this is a very high-performance chair in many different respects and unique on the market.
