1. An Adirondack chair composed of a polymeric material comprising: a seat;a back attached to the seat, the back having a plurality of side by side members, each of the members extending upwardly from the seat at an angle of 95° to 115° relative to at least a portion of the seat to define a laterall
1. An Adirondack chair composed of a polymeric material comprising: a seat;a back attached to the seat, the back having a plurality of side by side members, each of the members extending upwardly from the seat at an angle of 95° to 115° relative to at least a portion of the seat to define a laterally concave front surface;a lumbar support attached to the back, the lumbar support having a plurality of supports that together define at least one front surface which is longitudinally convex and laterally concave, each support attached to a respective member of the plurality of members of the back;wherein the seat, back and lumbar support are integrally molded as a unitary structure; andwherein the plurality of members of the back are comprised of a first member, a second member, a third member, a fourth member, a fifth member and a sixth member positioned adjacent to each other such that a first gap is defined between the first member and the second member, a second gap is defined between the second member and the third member, a third gap is defined between the third member and the fourth member, a fourth gap is defined between the fourth member and the fifth member and a fifth gap is defined between the fifth member and the sixth member. 2. The Adirondack chair of claim 1 wherein at least one of the supports of the lumbar support has a front surface extending between a first sidewall and a second sidewall opposite the first sidewall, the first and second sidewalls extending between 0.325 inches and 0.25 inches behind the front surface of the at least one support of the lumbar support such that the first and second sidewalls are substantially perpendicular to the front surface of the at least one support of the lumbar support. 3. The Adirondack chair of claim 1 wherein the plurality of supports is comprised of a first longitudinally convex support attached to the first member, a second longitudinally convex support attached to the second member, a third longitudinally convex support attached to the third member, a fourth longitudinally convex support attached to the fourth member, a fifth longitudinally convex support attached to the fifth member and a sixth longitudinally convex support attached to the sixth member wherein the supports of the lumbar support do not cover at least one of the first gap, second gap, third gap, fourth gap and fifth gap. 4. The Adirondack chair of claim 1 wherein the plurality of supports is comprised of a first longitudinally convex support attached to the first member, a second longitudinally convex support attached to the second member, a third longitudinally convex support attached to the third member, a fourth longitudinally convex support attached to the fourth member, a fifth longitudinally convex support attached to the fifth member and a sixth longitudinally convex support attached to the sixth member wherein the first support and sixth support each have a maximum thickness of 0.77 inches, the second support and fifth support each have a maximum thickness of 0.65 inches and the third support and fourth support each have a maximum thickness of 0.51 inches. 5. The Adirondack chair of claim 1 further comprising armrests attached to the back. 6. The Adirondack chair of claim 1 further comprising a base attached to at least one of the seat and the back. 7. The Adirondack chair of claim 1 further comprising at least one rib extending rearwardly and downwardly from a top portion of at least one of the chair back members to define a gap between the at least one rib and the at least one chair back member from which the at least one rib extends, the at least one rib being sized and configured to form a handle. 8. The Adirondack chair of claim 1 further comprising at least one rib and wherein each member of the plurality of members has a front and a rear, the rib attached to at least one member of the plurality of members such that the at least one rib extends beyond the rear of the at least one member. 9. The Adirondack chair of claim 8 wherein the rib is sized and configured to engage a chair back of another Adirondack chair to permit substantially straight chair stacking. 10. An Adirondack chair composed of a polymeric material comprising: a seat;a back attached to the seat, the back having a plurality of side by side members, each of the members extending upwardly from the seat at an angle of 95° to 115° relative to at least a portion of the seat to define a laterally concave front surface;a lumbar support attached to the back, the lumbar support having a plurality of supports that together define at least one front surface which is longitudinally convex and laterally concave, each support attached to a respective member of the plurality of members of the back;wherein the seat, back and lumbar support are integrally molded as a unitary structure; andwherein each member of the plurality of members has a top portion, a middle portion and a bottom portion, the top portion extending forwardly relative to the middle portion and extending to a position located above and in front of the longitudinally convex front surface of the lumbar support. 11. The Adirondack chair of claim 10 wherein the top portions of the plurality of members located in a center portion of the back defines a head rest. 12. An Adirondack chair composed of a polymeric material comprising: a seat;a back attached to the seat, the back being at an angle of 95° to 115° relative to at least a portion of the seat; anda lumbar support attached to the back, the lumbar support having a longitudinally convex front surface, the lumbar support extending from about 3.5 inches above a portion of the seat to about 11 inches above the portion of the seat such that a portion of the longitudinally convex front surface of the lumbar support is about 0.5 inches away from the back; andwherein the seat, back and lumbar support are integrally molded as a unitary structure;wherein the lumbar support is comprised of at least one support attached to the back, the at least one support of the lumbar support having a front surface extending between a first sidewall and a second sidewall opposite the first sidewall, the first and second sidewalls extending behind the front surface of the at least one support of the lumbar support such that the first and second sidewalls are substantially perpendicular to the front surface of the at least one support of the lumbar support; andwherein the first sidewall extends behind the front surface of the at least one support less in a middle portion of the first sidewall than in top or bottom portions of the first sidewall and wherein the second sidewall extends behind the front surface of the at least one support less in a middle portion of the second sidewall than in top or bottom portions of the second sidewall. 13.
