Air comprising supports for the posterior and the shins, respectively, of a chair occupant

A swivel stool or chair, comprising, in combination:

• a base member;
• a substantially vertical supporting column extending upwardly from said base member;
• a substantially flat forwardly and downwardly slanting set support arranged at a first level at the top area of said column for supporting the posterior of a stool user;
• a substantially flat shin support spaced from and disposed at a second level below and forward of said seat support, and slanting in the opposite direction thereof rearwardly and downwardly;
• means for interconnecting said seat support and shin support to allow for said spaced relationship, so that the user with his posterior resting on the seat support can assume a kneeling-like posture to distribute the body weight by resting the shines of his legs on said shin support, thereby permitting a natural, kneeling-like posture of balance with a substantially vertical position of the torso;
• the seat and shin support interconnecting means including an elongated frame member, the frame member having a first end and a second end opposite the first end, the shin support being mounted on the frame member in proximity to the first end thereof, the seat support being mounted on the frame member in proximity to the second end thereof, and the frame member being rotatably mounted to the vertical supporting column;
• and
• means mounting said seat support for simultaneous adjustment of the height of said seat and shin supports relative to said base member, said seat support being mounted so that said column is substantially forward of the center of said seat support.
