In essence, a chair is a bench with a backrest. Deceptively simple. Seated on a bench, your weight sends its' full force downwards. A successful bench needs to be only strong enough to support you in that one direction. Add the backrest and the resulting second direction of force sends the whole design into engineering upheaval. To make matters more complex, most sitters' backs are far more harsh critically than are their seats, so that backrest had better be in a good place when the lean meets it. And if all that weren't sufficient, bring aesthetics to the attempt to marry what is at the core of its' combination an odd unbalance. It's no wonder the chair is at the top of the list of designers' obsessions.
Please accept and add my latest submission to the world of chairs: the backspring chair.
Two simple, squared-off one inch thick multi-ply planes are joined by a semi-circle of white powder-coated 5/8" thick rolled aluminum. At the rear, the backrest is attached to the aluminum arc by an Xlarge wing nut on threaded rod that rides in a vertical slot allowing for up-and-down adjustability. The other end of the arc meets the underside of the bench-style white-colored hardwood chassis with another slot and wing nut attachment that allows the arc to be rotated forwards and back, effectively changing the degree of the backrest angle. At the base, stacked multi-ply feet visually tie the top pieces to the ground.
In all honesty, the resulting mass is surprising, too surprising for some.
