The RH Extend 100 has a medium height back and is designed to give full support and excellent strain relief.

The height adjustable chair back of the RH Extend incorporates a lumbar pad and a Tvedt cushion which together provide excellent support for the lumbar region, thorax and shoulders.

When the RH Extend 100 chair is placed in free float mode it will follow the movement of your body and maintain the flex pad against the lumbar region with the degree of support adjusted by a tension control knob.  This active style of sitting will promote a healthy posture and a comfortable working position.

The RH Extend footbase is supplied in grey lacquered aluminium with carpet castors fitted as standard.
