To evaluate the sleep-improving effects by the mattress easy to move and comfortable to sleep, we estimated sleep feelings by standardized OSA sleep inventory MA version and measured sleep quality by actigraph. Sixteen healthy subjects (6 males, 10 females), aged 61-66, were recorded, sleeping in their homes for 15 consecutive nights under two crossover designed conditions from Friday. A subject slept for 7 consecutive nights (4 adaptation nights and 3 nights for analysis) on his usual bedding first and then for 8 consecutive nights (4 adaptation nights, 3 nights for analysis and excluded last night) on a mattress easy to move and comfortable to sleep. The results showed the sleep on a mattress easy to move and comfortable to sleep indicated better sleep quality measured by actigraph. The results indicate that people may not sleep suitable bedding and the mattress easy to move and comfortable to sleep provide better sleep.
