The stowable seat of claim 1, wherein the first member is pivotably coupled to the seat bottom and support structure with respective first and second pivotable couplings, the second member is pivotably coupled to the seat bottom and support structure with respective third and fourth couplings, the third member is pivotably coupled to the support structure with a fifth coupling, and the fourth member is pivotably coupled to the second member with a sixth coupling and slidably and pivotably coupled to the third member with a seventh coupling. 3. The stowable seat of claim 2, wherein the fourth member includes a linking member defining a channel having a first end in a direction toward the sixth coupling and a second opposite end, the linking member coupled to the third member with the seventh coupling via the channel such that the seventh coupling facilitates the linking member pivoting and sliding relative to the third member. 4. The stowable seat of claim 3, wherein the second member includes an L-shaped configuration having the third and fourth pivotable couplings at respective ends thereof, and an extension portion extending at an acute angle from an end of the second member with the fourth coupling, the extension portion being pivotably coupled to the fourth member via the sixth coupling. 5. The stowable seat of claim 4, wherein when the stowable seat is in the deployed position, the seat bottom pivots the second member about the fourth pivotable coupling such that the extension portion via the sixth coupling draws the second end of the channel of the linking member into engagement with the seventh pivotable coupling so as to support the seat bottom in the seating position and prevent further downward rotation thereof toward the floor. 6. The stowable seat of claim 5, wherein the linking member is placed in tension between the sixth and seventh pivotable couplings when the seat bottom is in the deployed position. 7. The stowable seat of claim 4, wherein rotating the seat back toward the floor about the fifth pivotable coupling rotates the first and second members about the respective second and fourth couplings to the support structure so as to articulate the seat bottom to the stowed position in engagement with the floor. 8. The stowable seat of claim 7, wherein the seating side of the seat back is in engagement with the seating side of the seat bottom when the stowable seat is in the stowed position. 9. The stowable seat of claim 7, wherein rotating the seat back from the deployed position to the stowed position raises the seventh pivotable coupling in a direction away from the floor, which allows the linking member to raise and the second member to rotate about the fourth pivotable coupling in a direction toward the floor. 10. The stowable seat of claim 9, wherein during a portion of the rotation of the seat back from the deployed position to the stowed position, the third member slides the seventh pivotable coupling in the channel of the linking member in a direction from the second end to the first end of the channel without moving the linking member. 11. The stowable seat of claim 7, wherein the seventh pivotable coupling engages the first end of the channel of the linking member when the seat back and the seat bottom are in the stowed position thereby preventing further downward rotation of the seat back toward the floor. 12. The stowable seat of claim 7, wherein rotating the seat back from the deployed position to the stowed position automatically rotates and articulates the seat bottom from the deployed position to the stowed position via the linkage arrangement. 13. The stowable seat of claim 4, wherein rotating the seat bottom to the stadium position includes rotating the seat bottom in a direction away from the floor and toward the seat back such that the first member rotates about the first and second pivotable couplings and the second member rotates about the third and fourth pivotable couplings. 14. The stowable seat of claim 13, wherein the seating side of the seat bottom engages the seating side of the seat back when the stowable seat is in the stadium position, the seat back being in an upright seating position when the stowable seat is in the stadium position. 15. The stowable seat of claim 4, wherein the vehicle support structure includes first and second bracket members each fixed to the vehicle floor proximate the lower end of the seat back and the rearward end of the seat bottom. 16. The stowable seat of claim 15, wherein the first member is coupled to a first side of the first bracket member via the second coupling, the second member is coupled to a second opposite side of the first bracket member via the fourth coupling, and the third member is coupled to the second bracket member via the fifth coupling. 17. The stowable seat of claim 15, wherein the linkage arrangement facilitates suspending the seat bottom in spaced relation to the floor such that unobstructed access is provided between an underside of the seat bottom opposite the seating side and the floor when the seat bottom is in the deployed position. 18. A stowable seat arrangement for a vehicle having a floor, comprising: a seat back having an upper end, an opposite lower end and a seating side;a seat bottom having a forward end, a rearward end, a seating side and an opposite lower side; anda linkage arrangement including a first member pivotably coupled to the seat bottom and a vehicle support structure via respective first and second couplings, a second member pivotably coupled to the seat bottom and the support structure via respective third and fourth couplings, a third member fixed to the seat back and pivotably coupled to the support structure via a fifth coupling, and a fourth member having a channel formed therein, the fourth member pivotably coupled to the second member via a sixth coupling and slidably and pivotably coupled to the third member via the channel and a seventh coupling;wherein the linkage arrangement is configured to facilitate suspending the seat bottom in a deployed or seating position from the vehicle support structure in spaced relation to the floor, rotating the seat bottom to a stadium position substantially parallel to the seat back, and rotating the seat back and articulating the seat bottom to a stowed position whereby the seat bottom engages the floor and the seat back engages the seat bottom, the vehicle support structure being positioned proximate the lower end of the seat back and the rearward end of the seat bottom so as to provide unobstructed access between the underside of the seat bottom and the floor when the stowable seat is in the deployed position. 19. The stowable seat of claim 18, wherein when the stowable seat is in the deployed position, the seat bottom pivots the second member about the fourth pivotable coupling such that the sixth pivotable coupling draws the second end of the channel of the linking member into engagement with the seventh pivotable coupling so as to support the seat bottom in the deployed position and prevent further downward rotation thereof toward the floor, the linking member being placed in tension between the sixth and seventh pivotable couplings when the seat bottom is in the deployed position. 20. The stowable seat of claim 18, wherein rotating the seat back toward the floor about the fifth pivotable coupling rotates the first and second members about the respective second and fourth pivotable couplings so as to articulate the seat bottom to the stowed position in engagement with the floor, the seating side of the seat back engaging the seating side of the seat bottom in the stowed position.
