| Research Abstract |
In order to investigate the effects of the mattress hardness and the repulsion elasticity on nocturnal sleep, we experimented with 4 conditions. Distribution area of body pressure, body posture, sleep quality and physiological responses were mesaured and after sleep. There were significant differents in the number of limb position changes and the body area touching the mattress. Limb positions changed mere frequency in mattress A than in mattress D. The body area touching mattress A was greater than that touching mattress B. The time spent in each body posture during nocturnal sleep, duration spent in each body posture and limb position, maximum body pressure, and sleep quality did not differ significantly among mattresses.
