Objective: The aim of this study was to analyze the effectiveness of a new air cell cushion (Elaston cushion) made of gelatinous elastomers, a newly developed material with a novel structure on reducing pressure and temperature.
Methods: We compared the pressure and thermal responses of the Elastone cushion to three other available cushions (foam, gel-filled and air-filled villous) and four regular wooden or spongy chair seats. The skin temperature at the buttocks was also continuously measured for eight-hours sitting.
Results: The Elastone cushion reduced the peak pressure (39.7 mmHg) compared with foam (60.0 mmHg), gel-filled (60.3 mmHg) and air-filled cushions (69.3 mmHg), as well as with the wooden and spongy chair seats (84.7 to 200 mmHg). The peak temperature with the Elastone cushion was 29℃. Higher temperatures were found with the gel-filled (33.8℃), air-filled (35℃) and foam (35.9℃) cushions, as well as with the wooden and spongy chair seats (34.5 to 35.9℃).
Conclusion: Our findings clearly showed that the Elastone cushion was more advantageous in relieving pressure and minimizing temperature.
