  • Due to the coupling device may possibly be dispensed with a greater dimensioning of the chair frame, which would counteract the cantilever and would also have a higher weight of the chair result.
  • the bending moments are also limited to the curved connections between the bottom strut and the respective leg, whereby the material of the chair frame is less stressed.
  • the seating direction of the chair is to be understood as referring to a normal use of the chair and a straight sitting position with respect to the seat. Therefore, the main seat direction runs from a rear side of the chair, where usually the backrest is fixed, to a front side of the chair, where the user's feet are in a straight sitting posture.
