An ergonomic seating unit is disclosed for promoting active and dynamic sitting and eliminating fatigue resulting from extended sitting. The seating unit comprises a substantially egg-shaped, or ball-shaped, fluid filled, deformable balloon forming a flexible, mobile seat which conforms to the shape of a user when sat upon, and a main frame for loosely containing the flexible balloon being freely removable from the main frame when the seating unit is unoccupied and being movably wedged in place by the main frame when the seat is occupied.
Claims19
An ergonomic seating unit for promoting active sitting, the seating unit comprising:
- a substantially spherical-shaped, fluid filled, deformable balloon forming a flexible, mobile seat which conforms to a shape of a user when sat upon;
- and
- a main frame for loosely containing the flexible balloon within the main frame, the flexible balloon being freely removable from the main frame when the seating unit is unoccupied and being moveably wedged in place by the main frame when the seating unit is occupied,
- wherein the main frame comprises:
- a lower frame;
- an substantially U-shaped upper frame;
- and
- at least three vertical connecting tubes for connecting the lower and upper frames to one another, to create a space, in which the mobile seat is placed;
- wherein, when the deformable balloon is sat upon by the user, the balloon expands outwardly and is wedged in place in the space formed by the vertical connecting tubes;
- and
- wherein, when the deformable balloon is unoccupied by the user, the balloon assumes a substantially ball-shape and is unrestrained by the vertical connecting tubes.
