Claims19
A collapsible chair that is movable between a deployed configuration and a collapsed configuration, the collapsible chair comprising:
- (i) a collapsible seat comprising:
- a front portion;
- an opposing rear portion;
- and
- a seat membrane;
- (ii) a collapsible back comprising:
- a first back support member with a first arcuate portion and a second back support member with a second arcuate portion;
- and
- a back membrane;
- and
- (iii) at least two pivotally connected members;
- wherein the first arcuate portion and the second arcuate portion extend toward the front portion of the collapsible seat when the chair is in the deployed configuration;
- wherein the back membrane is coupled to the first and second back support members, spanning a distance between the first and second support members;
- wherein the collapsible seat is constructed and arranged to move together to collapse and fold;
- wherein the collapsible back is constructed and arranged to move together to collapse and fold;
- and
- wherein each back support member is positioned outside of and in contact with one of the pivotally connected member, keeping the back membrane taut between the arcuate portions when the chair is deployed, to create a curved lumbar support region of the back membrane that supports a lower back of a user.
A collapsible chair that is movable between a deployed configuration and a collapsed configuration, the collapsible chair comprising:
