The Effect of a New Gelatinous Elastomers Cushion on Reducing Pressure and Temperature

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.
