The chair of claim 1, wherein the hollow tank is adapted to receive a liquid mass and defines first and second openings, wherein the first opening is positioned proximate a top portion of the tank and receives the liquid mass to fill the tank, and wherein the second opening is proximate a bottom portion of the tank, and is used to drain the liquid mass from the tank. 3. The chair of claim 2, wherein the second opening is defined in a rear side of the tank and allows the liquid mass to drain when a top portion of the chair is tipped backward, toward the rear supports. 4. The chair of claim 2, wherein the second opening faces a side of the chair, and further comprising a wheel connected to the frame at the side of the chair. 5. The chair of claim 4, wherein the wheel allows rotational movement of the chair toward and away from the side, to thereby drain the liquid mass from the tank through the second opening. 6. The chair of claim 1, further comprising wheels connected to the frame proximate the lower ends of the rear supports. 7. The chair of claim 6, wherein the wheels are connected to the frame at a point such that the wheels are positioned above a ground surface when the chair is in an upright position and such that the wheels contact the ground surface when the top of the chair is pivoted backward relative to the ground surface. 8. The chair of claim 1, wherein the tank has a volume of 15-20 gallons. 9. The chair of claim 8, wherein the tank is formed from a plastic and has a height in the range of 6-12 inches and a base that is substantially square with sides having lengths in the range of 12-24 inches. 10. The chair of claim 1, further comprising a platform connected proximate the upper ends of the forward and rear supports, wherein the platform supports a seat, and wherein the ladder provides access to the platform. 11. A portable chair comprising: a seat, a frame that supports the seat, wherein the frame comprises first and second side supports each having a forward support and a rear support, wherein each of the forward and rear supports has an upper end and a lower end, wherein the seat is connected to the frame proximate the upper ends of the forward and rear supports; and a lower frame that connects the forward supports to the rear supports near the lower ends of the forward and rear supports; a ladder formed between the forward supports of the frame, wherein the ladder comprises one or more steps that provide access to the seat; a hollow tank connected to the lower frame, wherein the hollow tank has an opening defined therein for receiving a mass; and one or more ballast support members, wherein the one or more ballast support members are elongated members having opposing ends, wherein the tank is connected to the ballast support members between the ends, and wherein the ballast support members connect to lower frame at points between the tank and the ends. 12. The chair of claim 11, wherein each of the ballast support members has a plurality of holes defined therein between the tank and the ends for connection to the frame. 13. The chair of claim 11, further comprising a platform connected proximate the upper ends of the forward and rear supports, wherein the platform supports a seat, and wherein the ladder provides access to the platform. 14. The chair of claim 11, wherein the one or more ballast support members have adjustable lengths. 15. A portable chair comprising: a seat: a frame that supports the seat, wherein the frame comprises first and second side supports each having a forward support and a rear support, wherein each of the forward and rear supports has an upper end and a lower end, wherein the seat is connected to the frame proximate the upper ends of the forward and rear supports; and a lower frame that connects the forward supports to the rear supports near the lower ends of the forward and rear supports; a platform connected proximate the upper ends of the forward and rear supports, wherein the platform supports the seat; a ladder formed between the forward supports of the frame, wherein the ladder provides access to the platform; a hollow tank connected to the lower frame, wherein the hollow tank has an opening defined therein for receiving a mass. 16. The chair of claim 15, wherein the hollow tank is adapted to receive a liquid mass and defines first and second openings, wherein the first opening is positioned proximate a top portion of the tank and receives the liquid mass to fill the tank, and wherein the second opening is proximate a bottom portion of the tank, and is used to drain the liquid mass from the tank. 17. The chair of claim 16, wherein the second opening is defined in a rear side of the tank and allows the liquid mass to drain when a top portion of the chair is tipped backward, toward the rear supports. 18. The chair of claim 15, further comprising wheels connected to the frame proximate the lower ends of the rear supports. 19. The chair of claim 18, wherein the wheels are connected to the frame at a point such that the wheels are positioned above a ground surface when the chair is in an upright position and such that the wheels contact the ground surface when the top of the chair is pivoted backward relative to the ground surface. 20. A chair comprising: a frame having first and second forward and rear supports; and a ballast connected to a lower portion of the frame, wherein the ballast comprises a tank that holds 15-25 gallons of a liquid, and a rigid, elongated ballast support member that is positioned generally beneath the tank and is fixedly connected to a bottom portion of the tank and detachably connected to the lower portion of the frame. 21.
