sit bones
Seated weight bearers
Sit bones are the two bony protrusions at the base of the pelvis—the ischial tuberosities in anatomical terms.
They bear your weight when seated and are the points of contact with a chair or bicycle saddle: This saddle is too narrow for my sit bones.
Cyclists and yoga practitioners use the term frequently when discussing posture and comfort.
