9. A control assembly for a chair, comprising:
-
a base structure defining an upper portion having a first pivot point and a lower portion located below the upper portion and having a second pivot point spaced from the first pivot point, wherein the base structure is adapted to attach to aground-abutting base support structure; a seat support structure having a forward portion pivotably coupled to the upper portion of the base structure for rotation about the first pivot point and a rearward portion located rearward of the forward portion, and wherein the seat support structure is adapted to support a seated user; a back support structure having a forward portion pivotably coupled to the lower portion of the base structure for rotation about the second pivot point and a rearward portion located rearwardly of the forward portion, wherein the back support structure is adapted to move between a first position and a second position; a control link having a first end pivotably coupled to the rearward portion of the seat support structure for rotation about a third pivot point, and a second end pivotably coupled to the rearward portion of the back support structure for rotation about a fourth pivot point; a back shell member supported by the back support structure; and a mesh cover having a first surface adapted to support a seated user and a second surface opposite the first surface, wherein the cover is positioned over at least a portion of the back shell member. - View Dependent Claims (10, 11, 12)

16. A control assembly for a chair, comprising:
-
a base structure defining a first pivot point and a second pivot point spaced from the first pivot point, wherein the base structure is adapted to attach to a ground-abutting base support structure; a seat support structure pivotably coupled to the first pivot point, wherein the seat support structure is adapted to support a seated user; a back support structure pivotably coupled to the second pivot point, wherein the back support structure is adapted to move between a first position and a second position, and wherein the base structure does not move as the back support structure moves between the first and the second positions; a control link pivotably coupled to the rearward portion of the seat support structure for rotation about a third pivot point, and pivotably coupled to the back support structure for rotation about a fourth pivot point, wherein a distance between the first pivot point and the second pivot point is greater than a distance between the third pivot point and the fourth pivot point, and wherein the first pivot point is positioned at a greater vertical height than the second pivot point; a back shell member supported by the back support structure; and a mesh cover having a first surface adapted to support a seated user and a second surface opposite the first surface, wherein the cover is positioned over at least a portion of the back shell member. - View Dependent Claims (17, 18, 19, 20)
