據悉，人體脊椎的理想狀態是自然的“S”形，低質量的床墊會使脊椎彎曲，椎間盤的壓力得不到放松和緩解，造成人在睡眠中多次翻身以尋求更舒服的睡眠姿勢，從而引發頸椎病等多種疾病。傳統的彈簧床墊在長期使用(yong)后，有可(ke)能會出(chu)現彈(dan)簧變形扭曲，失(shi)去彈(dan)性而(er)造(zao)成(cheng)床面(mian)凹凸不平，甚至局(ju)部(bu)塌(ta)陷，嚴(yan)重影(ying)響睡眠質量(liang)。

    那么，怎樣選(xuan)擇一張好(hao)的(de)(de)床(chuang)(chuang)墊(dian)(dian)(dian)(dian)(dian)呢？筆者(zhe)采訪了專營進口床(chuang)(chuang)墊(dian)(dian)(dian)(dian)(dian)的(de)(de)劉先生。他說(shuo)，“首先要(yao)用(yong)手摸、拍床(chuang)(chuang)墊(dian)(dian)(dian)(dian)(dian)，如(ru)(ru)在表面能(neng)(neng)摸到彈(dan)(dan)簧，則說(shuo)明墊(dian)(dian)(dian)(dian)(dian)料太薄，睡時(shi)便會被(bei)頂著而覺得(de)不(bu)(bu)舒服。若(ruo)用(yong)手拍床(chuang)(chuang)墊(dian)(dian)(dian)(dian)(dian)，感覺有點“拋”或(huo)“空(kong)(kong)”，即表示床(chuang)(chuang)墊(dian)(dian)(dian)(dian)(dian)內膽與墊(dian)(dian)(dian)(dian)(dian)之間有空(kong)(kong)隙，不(bu)(bu)能(neng)(neng)有效承托，容易(yi)變形(xing)。”筆者(zhe)還了解(jie)到，床(chuang)(chuang)墊(dian)(dian)(dian)(dian)(dian)并(bing)非(fei)(fei)越厚(hou)越好(hao)，床(chuang)(chuang)墊(dian)(dian)(dian)(dian)(dian)的(de)(de)厚(hou)度跟它的(de)(de)承托力(li)沒有必然的(de)(de)關系，尤(you)其(qi)是彈(dan)(dan)簧床(chuang)(chuang)墊(dian)(dian)(dian)(dian)(dian)。若(ruo)彈(dan)(dan)簧厚(hou)度沒變，加厚(hou)底面墊(dian)(dian)(dian)(dian)(dian)料，換來(lai)的(de)(de)只(zhi)是較(jiao)佳的(de)(de)舒適度，而非(fei)(fei)承托力(li)。要(yao)想彈(dan)(dan)簧床(chuang)(chuang)墊(dian)(dian)(dian)(dian)(dian)耐用(yong)，選(xuan)用(yong)12-18厘米厚(hou)的(de)(de)彈(dan)(dan)簧最(zui)為(wei)理想。另外，將床(chuang)(chuang)墊(dian)(dian)(dian)(dian)(dian)豎(shu)直立(li)起，如(ru)(ru)果彎曲變形(xing)或(huo)不(bu)(bu)能(neng)(neng)立(li)起，說(shuo)明此床(chuang)(chuang)墊(dian)(dian)(dian)(dian)(dian)做(zuo)工比較(jiao)粗糙。
