In developing an automobile seat, comfort and human health are the most fundamental factors to be considered in design. Seat comfort can be improved from various aspects including material used for seat fabrication. Regarding to this matter, coconut fiber has exhibits many exceptional qualities which suggest it may enhance seat comfort and it is also economic. This study is aimed to determine the vibration comfort of two layers and three layers coconut fiber car seat at 40, 60 and 80 rpm by subjective rating and experiment. The result is later compared with result of unmodified car seat in the same condition. This study does not include seat-back measurement and the heat distribution of the cushion. Five male and five female subjects sat on the car seat mount on the transportation simulator which expose to three different rotational speed: 40, 60 and 80 rpm. Results of subjective rating, showed that majority subjects select three layers coconut fiber car seat as the most comfortable car seat. This finding is proved by the experimental data, where the vibration transmitted to the subjects when sitting on three layers coconut fiber car seat is the lowest compared with unmodified car seat is the highest. Three layers coconut fiber car seat is chosen as the most comfortable car seat through subjective rating. Vomit probability for the testing is relatively low, from 2.16% to 26.33% only and none subjects complaint that they are not feeling well.
