The Sack-Back Windsor chair was developed in the 1760's and exported from Philadelphia throughout the American colonies. These popular and comfortable chairs feature an oval seat with arms typically made up of a single steam-bent piece of wood and legs with a simple taper in the foot. Windsor chairs feature tapered joinery， weight on the seat of the chair causes the joints to strengthen not loosen as is the case in traditional tenon joinery. The strength and stability of the Windsor makes them a treasured American classic. As with all of our Windsors， each chair begins with locally milled green lumber. Every seat is hand-carved from Eastern White Pine. We do all of our turnings by hand on a lathe. Every spindle is rived and shaved on a shave horse to ensure the grain is left unbroken from end to end. This traditional process is repeated on the chair's back before steaming and bending. The legs are set using a traditional tapered lock joint which increases the chair's stability. Finally everything is wedged， hand sanded， and finished. (Please note that because each piece is handcrafted there may be slight variations between chairs， this adds to their historical accuracy and character.)
