This study combines concepts of bed design and sleep registrations to investigate how quality of spine support affects the manifestation of sleep in healthy subjects. Altogether, 17 normal sleepers (nine males, eight females; age 24.3±7.1 years) participated in an anthropometric screening, prior to the actual sleep experiments, during which personalised sleep system settings were determined according to individual body measures. Sleep systems (i.e. mattress and supporting structure) with an adjustable stiffness distribution were used. Subjects spent three nights of 8 h in bed in the sleep laboratory in a counterbalanced order (adaptation, personalised support and sagging support). During these nights, polysomnography was performed. Subjective sleep data were gathered by means of questionnaires. Results show that individual posture preferences are a determinant factor in the extent that subjects experience a negative effect while sleeping on a sagging sleep system. STATEMENT OF RELEVANCE: This study investigated how spine support affects sleep in healthy subjects, finding that the relationship between bedding and sleep quality is affected by individual anthropometry and sleep posture. In particular, results indicate that a sagging sleep system negatively affects sleep quality for people sleeping in a prone or lateral posture.
本研究将床具设计和睡眠记录的概念相结合，以调查脊柱支撑质量如何影响健康受试者的睡眠表现。共有 17 名正常睡眠者（9 名男性，8 名女性；年龄 24.3±7.1 岁）参加了人体测量筛查，然后在睡眠实验室中进行实际的睡眠实验，在此期间，根据个人身体测量确定个性化的睡眠系统设置。使用具有可调节硬度分布的睡眠系统（即床垫和支撑结构）。受试者以平衡的顺序在床上睡 8 小时，共三晚（适应、个性化支撑和下垂支撑）。在这些晚上，进行多导睡眠图检测。通过问卷收集主观睡眠数据。结果表明，个人姿势偏好是影响受试者在下垂睡眠系统上睡眠时体验负面效果程度的决定因素。相关性陈述：本研究调查了脊柱支撑如何影响健康受试者的睡眠，发现寝具和睡眠质量之间的关系受到个体人体测量和睡眠姿势的影响。特别是，结果表明，对于仰卧或侧卧睡眠的人来说，下垂的睡眠系统会对睡眠质量产生负面影响。
