Abstract
We examined the relationship between the air permeability of the mattress and the bed climate. Following a pilot study, we decided a protocol for experiment. Thirty healthy subjects(6 male and 8 female university students, and 8 male and 8 female adults) were exposed to 26℃(50%rh). Under a cross-over, blind design, subjects were randomly assigned to the following groups: Group 1 was assigned to lie on a breathable mattress for 30 minutes. In a week's time, they were assigned to lie on a nonporous mattress for 30 minutes. Group 2 was assigned in the reverse order. The temperature and humidity in the bed and the subjective evaluation were estimated. The results indicated that bed climate was better on the breathable mattress.
