Patent ID: 7401856

Claim:
A sit-stand stool comprising: a seat adapted to support a pelvis of a user; and a base supporting the seat and adapted to securely engage a floor, said base comprising a supporting element, connected to said seat, for pivotal movement about a pivot point and being adapted to provide a tilting motion of said seat, between a raised position and a forwardly inclined position, in a vertical plane about a pivot axis in accordance with a posture of a user, said seat having a bottom surface and said seat being connected to one end of said supporting element, at said bottom surface, said base further comprising at least one stop for constraining movement of said supporting element to prevent lateral tilting or inclination transverse to said vertical plane, said at least one stop being also adapted to prevent a rearward motion beyond said raised position, and a forward motion beyond said forwardly inclined position wherein in said forwardly inclined position said supporting element is inclined at 30 degrees or less with respect to said raised position in order to reduce risks for said user to lose stability, thereby providing said user with a further point of support in addition to his legs so as to stabilize a posture of his body without being in a completely seated position while allowing for movement between said raised and forwardly inclined positions.
