Now there are many sleep or various high-tech mattresses on the market, ranging from tens of thousands of yuan to more than 100,000 yuan. So what kind of mattress is right for you?Is the more expensive the better?
Let me tell you a way: when buying a mattress, you want to try to lie down. Remove the covering from the mattress and lie on your side with your hands folded and your knees bent like a fetus. It's a good idea to ask your partner or friend to take a picture behind your back** to gauge how big the gap is between your head and the mattress. When your head, neck, and spine form a straight line, if the gap between the head and the mattress is very obvious, reaching 6 cm or more, and the head is involuntarily tilted towards the mattress, it means that the mattress is too hard. If your hips are sunk into the mattress and your head is raised high by the mattress, the mattress is too soft. A mattress with moderate firmness and softness should easily and evenly support your body weight and allow you to sleep in a straight position (as shown).
The mattress should be replaced once every 10 years, because the mattress will have dust mites for a long time, and the mites live on eating human dander, don't worry, it won't bite you. Get along very harmoniously. But the problem is that the excrement of dust mites is harmful to the human body, and people often have rashes and various allergies because they sleep on an old mattress. So the mattress should be replaced every 10 years.
