This presentation will highlight important factors practitioners should consider when prescribing seating for people who sit for extended periods of time (comfort, pressure redistribution, aesthetics, function, posture, occupation, support and end user collaboration). These factors are based upon a mixed methods study that evaluated the pressure redistributing effects of WaterCell® technology in specialist seating. Average and peak pressures were then compared to self-reported discomfort scores, physiological observations, and semi structured interviews of twelve participants (five male, seven female).
