摘要: A split-seat chair includes a mechanism for stimulation of person's hips while seated in the chair, by generally simulating hip motion which occurs during walking, or allowing such movement user. Two platforms under respective buttocks person preferably move orbital motions about horizontal axis transverse to two pads orbiting 180° out phase relative one another. The speed is coordinated with rate circulation cerebrospinal fluid skull as it travels down into sacrum. moves pelvis gliding that partially mimics walking seated, thus reducing posturally caused lower back pain and stiffness.
