For smaller theatres with often very functional tribune constructions, it can be advisable to mount the seating on beams. This allows for leg mounting to be variably placed. Additionally, it is possible to remove and temporarily store complete beam units (3 to 5 seats) if required. The seat and backrest elements are identical to the ones built-in at Nuremberg Symphoniker. A robust steel frame construction completes the picture. Optionally, counterweights can be substituted with tip-up springs. This offers a weight-saving solution for seating which needs to be regularly removed.
