求翻译：一张床垫的价格可以从几百元到几十万元不等，而床垫的使用寿命至少是十年，因此，为了占据每天三分之一的睡眠时间能够舒适度过，让身心得到充分的休息，保证白天的工作和生活质量，在床垫上做一次投资还是相当值得的。是什么意思？

A mattress prices ranged from hundreds of dollars to hundreds of thousands of dollars, and life of the mattress is at least ten years, therefore, in order to occupy the one-third sleep time can comfortable spend a day, let the rest of the body and mind full, ensure the quality of work and life in the day, on the mattress a one investment is quite worth it.
