A chair with cooling and heating functions meeting the user’s thermal preferences was studied. In this study, explanatory variables affecting the probability of using chairs with cooling and heating functions were analyzed, revealing the following results. (1) The probability of using the chairs with cooling and heating functions can be expressed by the indoor temperature, seasonal differences, and individual differences. (2) The preferred mode differs depending on the season. (3) Individual differences in the probability of using the cooling mode and the heating mode are significant in the medium temperature range.
