This study was conducted to investigate the seasonal differences on comfort of mattress by means of body movement. Three parameters, i.e., frequency of body movements per hr, maximum and mean rest period time, were used as an indicatoro of comfort. Samples tested were A, B and C, hardness of which was 25, 29 and 44°, respectively. The softest sample was gained from the sample of 25°. Experiments were carried out in both summer and winter, and the results were compared with the sensory evaluation of touching on each sample. The results were as follows: 1)On evaluation using the 3 parameters, sample B was the best quality, which was followed by samples C and A in both seasons. 2)On evaluation of touching, sample A was the most favorite mattress, which was followed by samples B and C in both seasons. 3)The evaluation using the 3 parameters did not agree with the evaluation of touching. It is desirable that the selection of mattress should be based on the scientific justification.
