The cover for both the seat and back is of flame laminated foam on brushed nylon. Shock, vibration and noise protection - Sorbothane is a thermoset, polyether base, polyurethane material that combines high energy absorption with faultless memory. Its' unique liquid-solid properties allow it to simultaneously absorb shock and isolate vibration even at high frequency ratios. Sorbothane resists dynamic fatigue, creep and compression set, even at temperature extremes, without any significant change. In the field of ergonomics, Sorbothane plays a major role in protecting workers by reducing the effects of harmful energy.
Studies show the majority of impact and vibration related injuries occur in a pattern.
First there is the pain and fatigue resulting from the work being done. Next comes the mental fatigue, causing the worker either to slow down which reduces efficiency, or to adapt his posture, leading to further injury.
