床垫越软初睡越舒适但长期承托力不足易加重腰痛；越硬支撑好但压力点不适、侧睡易压肩。真正好的助眠垫是'表层软+芯层硬'的分层结构，而非单一软硬

Unverified软硬度与承托支撑力是两回事：床垫可以'表面软但支撑强'（软舒适层+硬支撑芯）。追求柔软触感时不能牺牲支撑层，否则睡感软塌但腰部无支撑导致晨起腰酸87% similarUnverified枕头高度支撑性和柔软舒适度矛盾：太软的枕头睡下去会塌陷失去有效高度导致颈椎悬空。追求承托选高密度记忆棉/乳胶，追求柔软包裹感选羽绒但需接受支撑弱86% similarUnverified羽绒枕柔软塑形性好但几乎无支撑力，适合喜欢柔软触感的仰睡者，不适合需要颈椎支撑或侧睡者；且羽绒易钻绒、需高蓬松度（fillpower）填充才不易塌陷85% similarUnverified床垫越软包裹越舒适但支撑越弱、越易陷腰；体重大或腰不好的人不能只看『躺着舒服』，软垫短期舒适长期可能加重腰椎负担，需在软硬间为支撑力妥协84% similarUnverified偏好较硬床垫的人群（如老年人、腰椎问题需硬支撑者）不太适合，该床垫为中等偏软的弹簧+乳胶组合，睡感不算硬84% similar
