    AbstractIt 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'. This refers to the yielding of the mattress to such an extent that the occupant comes into close contact with the hard base of the bed: an important condition to avoid as it is thought to represent an aggravated risk factor for pressure ulcers. 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.
