To promote better sleep, we designed a motion mattress producing slow and swaying movements by slow regional changes of height generated by 10 separated air cells underneath. The motion induces a stretching movement and a gentle swaying movement of the user’s body. In this study, we examined its sleep-improving effects. Subjects who were not fully satisfied with their sleep were recruited. The study was performed for three periods, each of which was a week with a distinct condition. The first period was assigned as pre-experimental (PRE) period when the subjects sleep using their own mattress. The other two periods were assigned as motion mattress active (MM1) period and motion mattress control period. All subjects were randomly divided into two groups for a cross-over study. The subjects recorded electroencephalograms at home for themselves during these 3 weeks. Subjects were asked to perform sleep questionnaires. We examined the effects of this motion mattress at home by measuring the subjective and objective sleep parameters of 11 subjects. As for the objective sleep parameters, Sleep efficiency, NREM sleep stage 3, and awakening index significantly improved during MM1 compared with PRE (p < 0.05). As for the subjective sleep quality, subjects gave significantly higher value to the questions about “falling asleep quickly”, “slept soundly”, and “woke up refreshed”. Our newly developed motion mattress improved both objective and subjective sleep parameters.

为了促进更好的睡眠，我们设计了一种运动床垫，该运动床垫通过下方10个独立气囊产生的缓慢的区域高度变化来产生缓慢而摇摆的运动。该运动引起使用者身体的伸展运动和轻柔的摇摆运动。在这项研究中，我们检查了其改善睡眠的作用。招募对他们的睡眠不完全满意的受试者。该研究进行了三个阶段，每个阶段都是一周，情况各有不同。当受试者使用他们自己的床垫睡觉时，将第一时期指定为实验前（PRE）时期。其他两个时期被指定为运动床垫活动（MM1）时期和运动床垫控制时期。将所有受试者随机分为两组进行交叉研究。在这三个星期中，受试者在家中自己记录了脑电图。要求受试者进行睡眠问卷。我们通过测量11位受试者的主观和客观睡眠参数，检查了这种运动床垫在家里的效果。至于客观睡眠参数，MM1期间的睡眠效率，NREM睡眠第3阶段和觉醒指数与PRE（p  ＜0.05）。至于主观睡眠质量，受试者对“快速入睡”，“睡得很好”和“醒来后醒”的问题给予了更高的评价。我们新开发的运动床垫改善了客观和主观睡眠参数。
