GENUS SIDE CHAIR
In order to expand the Genus Range into a broader family, the Genus side chair was added to the highly successful Task Chair range, a complimentary range of stacking, linking, arm and armless chairs. The challenge was to retain the aesthetic similarity so that the family retained a unity of appearance and comfort. A simple engineered tubular steel frame supports an injection moulded seat and back components. The seat is upholstered and has a under shroud to protect the upholstery when the chairs are stacked. The back has a mesh membrane support which can also be upholstered. The arms rests, also injection moulded, are fitted to the outer side of the back and under side of the seat. The chairs can stack four high or 10 high on a trolley. The steel four leg frame has ‘high heels’ fitted to the base of each leg, which can be easily removed and replaced with castors to make the chairs mobile. Within the same range ‘light work’ swivel chairs have been included, mounted on a five star base with simple tilt mechanisms. Swivel conference chairs on four star base and stools at two different heights complete the family.
The Genus side chair is an addition to the Task Chair range. The brief required a complimentary side chair with a mesh back. The design challenge was how to make the mesh on a smaller scale chair that was equally as comfortable as the task chair. In order to ascertain it’s feasibility we built a number of rigs with different size backs with mesh applied. We were able to establish that a high degree of comfort could be achieved from a back of a certain size. From this development we had a number of prototype steel frames constructed in order to assemble back, seat and arms models, all made in machined ABS. Most of the development focused around the back, its attachment to the steel frame, the clipping connection of the mesh back inner frame to the structural outer frame and the arm connections to the back and seat. Structural analysis indicated that components were strong enough to pass BIFMA+20% testing, the stress levels being severest at the connection of the back to the steel frame and the arms to the back. Final machined back prototypes were produced in nylon to determine the fitting of the mesh, the level of comfort and confidence in the overall strength of the chair prior to tooling the components.
