2. The foldable chair assembly of claim 1 , wherein the chair includes a chair back that is pivotally attached to a chair seat.
3. The foldable chair assembly of claim 1 , wherein the chair is pivotable with respect to the base.
4. The foldable chair assembly of claim 1 , wherein the chair includes a sling-type occupant support.
5. The foldable chair assembly of claim 1 , wherein each leg biasing member is an elastic band extending from the respective pivot pin to the respective leg pivot locating pin.
6. The foldable chair assembly of claim 1 , wherein the chair is removably supported on said base via a swivel pin.
7. The foldable chair assembly of claim 1 , wherein each leg includes a respective leg pivot locating pin, wherein each leg includes a respective leg biasing member, wherein each leg biasing member is configured to bias each leg pivot locating pin into a respective leg pivot slot.
8. A foldable chair assembly, comprising:
a chair; and
a base having four legs pivotally attached via a respective pivot pin, wherein each leg is independently pivotable with respect to any other leg, wherein the base includes a series of leg pivot slots associated with each respective leg, and wherein each leg includes a respective leg biasing member configured to bias a leg pivot locating pin of each leg into a respective leg pivot slot.
9. The foldable chair assembly of claim 8 , wherein the chair is configured to be swiveled with respect to the base.
10. The foldable chair assembly of claim 8 , further comprising:
a chair swivel having a swivel pin receivable within a hushing.
11. The foldable chair assembly of claim 8 , wherein each leg biasing member is an elastic band extending from the respective pivot pin to the respective leg pivot locating pin.
12. The foldable chair assembly of claim 8 , wherein each leg biasing member is a coil spring extending from the respective pivot pin to the respective leg pivot locating pin.
13. A foldable chair assembly, comprising:
a base having at least three legs pivotably attached to the base via a respective pivot pin, wherein a first leg of the at least three legs is pivotably adjustable with respect to the base, wherein a second leg of the at least three legs is pivotably adjustable with respect to the base, wherein a third leg of the at least three legs is pivotably adjustable with respect to the base, wherein the first leg, the second leg, and the third leg of the at least three legs are independently pivotably adjustable with respect to each other, wherein the at least three legs are pivotably attached to the base via a respective pivot pin, wherein each pivot pin is received within a slotted pivot point of the respective leg, wherein each leg includes a respective leg pivot locating pin, and wherein each leg includes a respective leg biasing member, wherein each leg biasing member is configured to bias the respective leg in a linear direction that is parallel to a line extending from a first end of each leg to a second end the leg.
14. The foldable chair assembly of claim 13 , wherein the chair includes a chair back that is pivotally attached to a chair seat.
15. The foldable chair assembly of claim 13 , wherein the chair is pivotable with respect to the base.
16. The foldable chair assembly of claim 13 , wherein the chair is configured to be swiveled with respect to the base.
