研究显示[1]，不同软硬度的床显著影响着一个人睡着时的翻身次数、苏醒次数、苏醒时长、睡眠品质、身体舒适感及白天精神状况。
杜克大学教授Dr. Andy Krystal and Jack Edinger做过的一项实验显示[2]，能在7张床里面通过试睡而选到最适合自己的床的机率小于15%。由于人清醒时与睡着时的肌肉状态不同[3]，在店里买床能做出准确的选择是极度需要运气的。
由于每个人身高，体重，肩宽，臀宽，肌肉状态，腰椎形状，腰椎状态，睡姿习惯等因素都不同，许多研究证实[4]，没有特定软硬度的床垫适合多数人，每一种软硬度都有可能最适合你，而这背后的奥秘仍然是个谜。

如果能将不同软硬的床垫搬回家，分别体验数晚并实时纪录身体状况，就可能找到那张最合适你的床而在现实生活中，却没有这个选项。
