a seat;

a post positioned below and attached to the seat;

a base positioned below and attached to the post;

an inflatable bladder positioned below and attached to the base; and

a guard attached to the base;

wherein the inflatable bladder comprises a complete spherical dome, the complete spherical dome comprising less than 35 percent of a sphere, and wherein the inflatable bladder covers greater than 35 percent of an underside of the base, and further wherein the guard comprises a cylindrical wall centered on a longitudinal axis of the post and extending downward from the base at a position spaced radially outward from the inflatable bladder with a bottom edge located above a bottom of the inflatable bladder when the inflatable bladder is fully inflated such that a tangent line to the inflatable bladder intersects the bottom edge and forms an angle of greater than or equal to about 75 degrees relative to the post.

2. The seating device of claim 1 , wherein the seat comprises a padded saddle seat.

3. The seating device of claim 1 , further comprising at least one sensor configured to sense positional attributes of the seating device.

4. The seating device of claim 1 , wherein the post comprises an adjustable post comprising an inner element and an outer element.

5. The seating device of claim 1 , wherein radius of curvature of the inflatable bladder is greater than 0.5 feet and less than four feet.

6. The seating device of claim 1 , further comprising a bladder fill mechanism provided in the base.

7. The seating device of claim 6 , wherein the bladder fill mechanism comprises a valve.

8. A seating device, comprising:

a saddle seat supported by a post;

a base positioned below and attached to the post, the base having an inflatable bladder positioned on a bottom side of the base and;

a guard comprising a cylindrical wall centered on a longitudinal axis of the post and extending downward from the base at a position spaced radially outward from the inflatable bladder with a bottom edge located above a bottom of the inflatable bladder when the inflatable bladder is fully inflated;

wherein the inflatable bladder comprises a complete spherical dome, the complete spherical dome comprising less than 35 percent of a sphere, and wherein the inflatable bladder covers greater than 35 percent of an underside of the base such that a tangent line to the inflatable bladder intersects the bottom edge and forms an angle of greater than or equal to about 75 degrees relative to the post.

9. The seating device of claim 8 , wherein the guard comprises a plurality of movable elements affixed thereto.

10. The seating device of claim 8 , further comprising at least one sensor configured to sense positional attributes of the seating device.

11. The seating device of claim 8 , wherein the post comprises an adjustable post comprising an inner element and an outer element.

12. The seating device of claim 8 , wherein radius of curvature of the inflatable bladder is greater than 0.5 feet and less than four feet.

13. The seating device of claim 8 , further comprising a bladder fill mechanism associated with the inflatable bladder.

14. The seating device of claim 13 , wherein the bladder fill mechanism comprises a valve.

15. A seating device, comprising:

an inflatable bladder configured to be positioned proximate a horizontal surface, the inflatable bladder affixed to a base;

a post affixed to the base;

a seat affixed to the post;

a guard comprising a cylindrical wall centered on a longitudinal axis of the post and extending downward from the base at a position spaced radially outward from the inflatable bladder with a bottom edge located above a bottom of the inflatable bladder when the inflatable bladder is fully inflated;

wherein the inflatable bladder comprises a complete spherical dome, the complete spherical dome comprising less than 35 percent of a sphere, and wherein the inflatable bladder covers greater than 35 percent of an underside of the base such that a tangent line to the inflatable bladder intersects the bottom edge and forms an angle of greater than or equal to about 75 degrees relative to the post.

16. The seating device of claim 15 , wherein the guard comprises a plurality of movable elements affixed thereto.

17. The seating device of claim 15 , further comprising at least one sensor configured to sense positional attributes of the seating device.

18. The seating device of claim 15 , further comprising a bladder fill mechanism associated with the inflatable bladder.
