Chair

A chair comprising:

• a supporting frame;
• a back portion;
• a seat portion having a central zone;
• and
• a seat support for operatively supporting the seat portion from the supporting frame, wherein the seat support comprises a relatively rigid base member and a plurality of resilient support members that extend outwardly from the base member with their outer portions located generally along respective sides of the central zone of the seat portion and configured to support a seated occupant when the seated occupant's weight is centrally located in the central zone, but which enable an angular change of the seat portion to the side if the seated occupant's weight is offset to the side of the central zone of the seat portion, and wherein the resilient support members comprise elongate members with a vertical cross section, wherein the vertical cross section comprises a wide dimension and a narrow dimension, wherein the narrow dimension is a substantially vertical dimension and the wide dimension is a substantially horizontal dimension.

A chair comprising:

• a supporting frame;
• a back portion;
• a seat portion having a central zone and two exterior side zones, one on either side of the central zone, wherein the exterior side zones are resiliently flexible to enable the exterior side zones to deform downwardly from the central zone under the weight of an occupant's legs if the occupant sits sideways on the seat portion;
• and
• a seat support for operatively supporting the seat portion from the supporting frame, wherein the seat support comprises a relatively rigid base member and a plurality of resilient support members that extend outwardly from the base member with their outer portions located generally along respective sides of the central zone of the seat portion and configured to support a seated occupant when the seated occupant's weight is centrally located in the central zone, but which enable an angular change of the seat portion to the side if the seated occupant's weight is offset to the side of the central zone of the seat portion.

A chair comprising:

• a supporting frame;
• a back portion;
• a seat portion having a central zone;
• and
• a seat support for operatively supporting the seat portion from the supporting frame, wherein the seat support comprises a relatively rigid base member and a plurality of resilient support members that are generally radially extending from the base member and that operatively support the central zone of the seat portion and are configured to support a seated occupant when the seated occupant's weight is centrally located in the central zone, but which enable an angular change of the seat portion to the side if the seated occupant's weight is offset to the side of the central zone of the seat portion, and which also enable forward angular movement of the seat portion as the occupant applies weight forwardly to the seat portion, and wherein the resilient support members comprise elongate members with a vertical cross section, wherein the vertical cross section comprises a wide dimension and a narrow dimension, wherein the narrow dimension is a substantially vertical dimension and the wide dimension is a substantially horizontal dimension.
