About the Product

Dynamic, architectural and ergonomic
B_Run adjusts to the user in every way using intelligent technology, readable functionality, ergonomics and optical and functional diversity. Its clear, graphic design language is restrained, elegant and self-confident.

Combining the various elements of the B_Run office chair enables a high level of individualisation. B_Run, a swivel chair with a shape that is harmoniously integrated in Bene’s product portfolio.

The flexible design of the swivel chair is shown by the backrest: mesh back, upholstered back or PP membrane in two different heights. Four different armrests are available: fixed armrest, loop armrest, multifunctional 3D and 2D armrests. Even more comfort is provided by the lumbar support, the seat tilt/depth adjustment and a pneumatic spring with mechanical depth spring. The synchro-mechanism (seat and back) supports dynamic sitting and optimises movement.
