Chair, a support, and components

A chair comprising:

• a seat portion;
• a back portion comprising a one-piece frame of unitary construction having an upper transverse member at an upper portion thereof, and a lower transverse member at a lower portion thereof, the upper transverse member being positioned a greater vertical distance from the seat portion than the lower transverse member, the one-piece frame of unitary construction further comprising at least two spaced apart side members extending between and connecting to the upper transverse member and to the lower transverse member with the upper and lower transverse members extending between the two spaced apart side members, each side member having an inner edge and an outer edge, wherein the inner edges of the side members face towards each other and the outer edges of the side members face away from each other, each side member being generally L-shaped in cross-section and having a front face that faces a seated occupant in use, and a flange positioned at the outer edge of the side member, the flange extending at least a major portion of the length of the side member and in a direction generally rearwardly from the front face, wherein each side member comprises a plurality of attachment features comprising hook features on a forward facing surface of the side member, the hook features comprising an upright that extends in a forward direction from a portion of the side member and an overhang connected to the upright and spaced from said portion of the side member, wherein the overhang extends in a direction that is transverse to the forward direction away from the inner edge of the side member toward the outer edge of the side member;
• and a compliant support surface comprising a plurality of elongate vertical members and a plurality of elongate horizontal members extending between and supported by the side members, wherein at least some of the elongate vertical members are engaged with the hook features between the elongate horizontal members, the compliant support surface being disposed directly against the front face of the side members.

A chair comprising:

• a main transom, a recline mechanism, and a seat portion;
• a back portion comprising a one-piece frame of unitary construction having an upper transverse member at an upper portion thereof, and a lower transverse member at a lower portion thereof, the upper transverse member being positioned a greater vertical distance from the seat portion than the lower transverse member, and at least two spaced apart side members extending between and connected to the upper transverse member and to the lower transverse member with the upper and lower transverse members extending between the two spaced apart side members, each side member having an inner edge and an outer edge, wherein the inner edges of the side members face each other and the outer edges of the side members face away from each other, each side member being generally L-shaped in cross-section and having a front face that faces a seated occupant in use, and a flange positioned at the outer edge of the side member, the flange extending at least a major portion of the length of the side member and in a direction generally rearwardly from the front face, wherein each side member comprises a plurality of attachment features comprising hook features on a forward facing surface of the side member, the hook features comprising an upright that extends in a forward direction from a portion of the side member and an overhang connected to the upright and spaced from said portion of the side member, wherein the overhang extends in a direction that is transverse to the forward direction away from the inner edge of the side member toward the outer edge of the side member, the one-piece frame of unitary construction further comprising at least one support member extending from the lower portion thereof and mounted to at least one of the main transom, the recline mechanism, and the seat portion, to support the back portion in the chair;
• and a compliant support surface comprising a plurality of elongate vertical members and a plurality of elongate horizontal members extending between and attached to the side members, wherein at least some of the elongate vertical members are engaged with the hook features between the elongate horizontal members, the compliant support surface being disposed directly against the front face of the side members.
