The thermal comfort is one of the factors that can affect sleep quality. In the present study, the effects of two quilts with different thermal insulation on the human thermal sensation were compared. Four subjects were exposed in a climate chamber to different thermal conditions including three indoor air temperatures: 15ᵒC, 20ᵒC and 25ᵒC. Thermal sensation assessment of the bed micro-environments was obtained through subjective thermal perception collected by questionnaires. The results showed that 30 min exposure was not enough for the subjects to adapt to the thermal condition in the bed while using the quilt (600 g) at low indoor air tem-perature. Based on the findings from the present study, it is recommended to provide individ-ual control of the bed micro-environment to achieve thermal comfort.
