STF78 A034506 The aim of this study was to establish an overview over pressure relieving and pressure distributing properties of a selection of seat cushions available in the Norwegian market, and to document level of discomfort for persons seated in the same static position for a longer period of time. 15 subjects participated in the study. Pressure data was collected over a continuous period of 90 minutes. Subjects were asked to respond to seven statements related to their subjective feeling of sitting comfort, starting at the 10th minute, with 20 minutes intervals thereafter. Subjects reported extensive discomfort after 90 minutes. None of the cushions lost their carrying capacity or resilience during the test period. Nevertheless, pressure values and distribution varied considerably. This underlines the fact that choice of seat cushion should always be considered as highly individual and dependent on multiple factors.
