A chair having a base, a seat support mounted on the base, and a seat back support coupled with the seat support. The chair further includes a seat support assembly coupled with the seat support and a back support assembly coupled with the back support. The seat support assembly is a multi layered piece having a base layer, an intermediate layer, a gel pad, a tail pad, and a top layer. Once assembled the seat support assembly has a relief area that corresponds to the tail bone region of the user. The back support assembly is multi layered piece having a base layer, an intermediate layer, a support pad assembly, and a top layer. The ordering of the layers and the orientation of the support pad assembly provide support to the user without any direct or focalized pressure being distributed to specific regions of the body.

What is claimed is: 1. A chair having a base, a seat support mounted on the base, and a seat back support coupled with the seat support, the chair comprising: a seat support assembly coupled with the seat support, the seat support assembly having a urethane foam base layer with a void, a urethane f
What is claimed is: 1. A chair having a base, a seat support mounted on the base, and a seat back support coupled with the seat support, the chair comprising: a seat support assembly coupled with the seat support, the seat support assembly having a urethane foam base layer with a void, a urethane foam intermediate layer coupled with the urethane foam base layer, the urethane foam intermediate layer having an inner void and an outer void, a gel pad having a void, the gel pad being received within the outer void of the urethane foam intermediate layer and coupled with the urethane foam base layer, a urethane memory foam top layer coupled with the urethane foam intermediate layer, wherein the void of the urethane foam base layer and the inner void of the urethane foam intermediate layer and the void of the gel pad align to create a relief area in the seat support assembly, and a urethane foam tail pad coupled with the seat support and received within the void in the urethane foam base layer; and a back support assembly coupled with the back support, the back support assembly having a urethane foam base layer, a urethane memory foam intermediate layer coupled with the urethane foam base layer, a support pad assembly coupled with the urethane memory foam intermediate layer, and a urethane memory foam top layer coupled with the urethane memory foam intermediate layer and the support pad assembly, wherein the support pad assembly includes a pair of lower pads, a pair of upper pads, a lumbar pad, and a center pad, each of the pads being made from urethane foam. 2. The chair as recited in claim 1, wherein the density of the urethane foam is less than the density of the urethane memory foam. 3. The chair as recited in claim 2, wherein the density of the urethane foam is between 2.5 and 2.6 pounds per cubic foot (PCF). 4. The chair as recited in claim 3, wherein the density of the urethane memory foam is 4 PCF. 5. The chair as recited in claim 1, further including a lumbar adjustor coupled with the back support, the lumbar adjustor being sandwiched between the back support and the urethane foam base layer. 6. The chair as recited in claim 5, wherein the lumbar adjustor includes a knob, a cable, and a flex plate, wherein rotation of the knob causes the flex plate to bow outwardly from the back support. 7. The chair as recited in claim 6, wherein the flex plate is aligned with the lumbar pad. 8. A seat support assembly for use with a chair, the seat support assembly comprising: a urethane foam base layer with a void, a urethane foam tail pad received within the void in the urethane foam base layer, a urethane foam intermediate layer coupled with the urethane foam base layer, the urethane foam intermediate layer having an inner void and an outer void, a gel pad having a void, the gel pad being received within the outer void of the urethane foam intermediate layer and coupled with the urethane foam base layer, and a urethane memory foam top layer coupled with the urethane foam intermediate layer, wherein the void of the urethane foam base layer and the inner void of the urethane foam intermediate layer and the void of the gel pad align to create a relief area in the seat support assembly, and further wherein the density of the urethane foam is less than the density of the urethane memory foam. 9. The seat support assembly as recited in claim 8, wherein the density of the urethane foam is between 2.5 and 2.6 pounds per cubic foot (PCF). 10. The seat support assembly as recited in claim 9, wherein the density of the urethane memory foam is 4 PCF.
