It is widely recognised that mattresses have a finite life-span. In particular, hospital mattresses, typically made from polymer foam materials, are known to degrade over a period of years. Fatigue of a mattress in this way leads to a phenomenon known as 'bottoming'. ⋯ The authors have developed a portable, easy--to use, interactive device that quickly gives accurate information as to the condition of a mattress in a clinical setting. The device is validated against accelerated fatigue, pressure mapping of bottoming with healthy volunteers, and service life of 150 mattresses. The QUINCE SUPPORT SCORE provides an objective and valid basis for a mattress replacement programme.
