Abstract
This paper presents a thermal evaluation of the seats and backrest of the Luffa Cylindrica. In this study it was compared the thermal effects in the use of the natural fibers (Luffa Cylindrica) and polyurethane foam .Two chairs were covered in the backrest and seat, one with natural fiber and another with polyurethane foam. The body region subject selected for an assessed was a lumbar region and a posterior thigh, regions that are in contact with the seats. Seven thermographic images were performed with a time interval of 10 minutes between them, first images were collected from the backrest containing Luffa Cylindrica and later images of the back that contained a polyurethane foam were collected. After the test, it was possible to identify a temperature difference between the two materials. Considering the results obtained by the authors, the application of the Luffa Cylindrica to seat and backrests is of great relevance since they are a sign of greater thermal comfort for the individuals.
