The ObusForme® Lowback Backrest & Seat Combo offers a complete and comfortable sitting experience that transforms ordinary chairs into ergonomically correct seating. Unlike ordinary "L"-shaped chairs, the "S"-shape of the ObusForme® Backrest molds your spine into a more anatomically correct position and helps to enhance overall posture by supporting proper spinal alignment. The uniquely designed ObusForme Seat also evenly distributes body weight and encourages proper alignment of the pelvis and thighs for extended sitting comfort.
