Seating device

摘要

A seating device is provided. The seating device includes 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, sensing electronics configured to sense orientation of the seating device and provide orientation data to a remote computing device, and a guard attached to the base. The guard includes 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. The inflatable bladder includes a complete spherical dome wherein when the inflatable bladder is filled, a tangent line to the inflatable bladder intersects the lower edge and forms an angle of greater than or equal to about 75 degrees relative to the post.
