Abstract: A chair includes a first side member, a second side member, a back cross member, a first flex member, and a second flex member. The first side member supports a first side of the chair and the second side member supports a second side of the chair. The back cross member is situated between the first side member and the second side member and rotates relative to the first side member and the second side member. The first flex member is coupled to the first side member and the back cross member and twists as the back cross member rotates relative to the first side member and the second side member. The second flex member is coupled to the second side member and the back cross member and twists as the back cross member rotates relative to the first side member and the second side member.

Abstract: A recliner has a chair frame that provides support to a seat and back rest. The frame includes a recliner assembly that includes a bracket that is connected to the backrest enabling reclining movement of the backrest as the bracket moves through a correspondingly shaped bracket slot in a recliner base plate, and where the bracket rotates about an axis that approximates the position of the rotational axis of the hip of a seated user. The reclining chair can also be part of a modular system of components that enable one or more seating units to be in a spanned or ganged configuration.

Abstract: A glider has a chair frame that provides support to a seat and back rest. The frame includes a glider structure that is connected to each side frame member and includes a glider rail and a first and second elongate arcute glider tracks, a first and second wheel assembly, where the glider rail is attached to the backrest and the seat and enables gliding movement of the backrest and seat as the wheel assembly moves through a curved profile in the glider track. The glider chair can also be part of a modular system of components that enable one or more seating units to be in a spanned or ganged configuration.
