To get a good night's sleep, your sleep environment is important. Of these, the mattress is of course the most important.

All right, let's go get some mattresses!

Into the furniture store, all kinds of brands and styles, just look at the eyes, do not know how to choose. The shopping guide staff is very warm, all kinds of introductions and compliments. However, after listening to it, it seems more difficult to choose.

Why don't you lie down and try?

I heard that springs are much better, so you sit on the edge of the bed and repeatedly feel the elasticity with your hips. I heard that the mattress is soft, so you fall on your back and feel its hardness. In the end, if you don't have the money, you probably bought the most expensive one, but it doesn't seem to be the best one for you.

So, how to choose a mattress? Actually, you don't have to.

Choose a mattress, look at these three aspects is enough: size, material, soft and hard.

What size mattress to buy?

If you sleep alone, you can buy a single bed, 90 cm wide. Of course, you can buy a bigger one, as long as your bedroom is big enough. If you are sleeping with two people, you must buy a double bed, but there is a problem: the double bed you buy is probably not a real double bed.

Why do you say that? Because there is a so-called double bed, its width is 150 cm, it is obvious that if you want to continue to enjoy the space of 90 cm single bed, then the other side can only use 60 cm. You can figure out how to draw the 38th parallel.

Why mention sleeping space on the bed? Because the smaller the space, the more likely you are to be disturbed when you sleep. Imagine you're sleeping soundly when suddenly an arm or a leg rests on you. Or, he turns to his side and blows right into your nose. All of these things can interfere with your sleep.

So, if you want to buy a double bed, it is best to choose a wider, I recommend 180 cm wide, this is the true sense of the double bed.

What material should I choose for the mattress?

At present, there are two main mattress materials on the market: one is latex, and the other is polyurethane. Which one to choose?

In 2017, a team from the Department of Biomedical Engineering at the National University of Singapore did an interesting experiment in which they compared the effects of two types of mattresses, latex and polyurethane, on human contact pressure.

The experimental results show that compared with polyurethane mattresses, latex mattresses can better reduce the peak pressure of the human torso and buttocks. In layman's terms, it means sleeping on it without breaking your bones.

Therefore, at this point, I recommend choosing latex.

Mattress soft and hard how to choose

Note that this is the point of choosing a mattress. Because the softness and firmness of the mattress have a very important impact on maintaining the health of the spine.

There is no doubt that the mattress is too hard or too soft, of course, is not OK, the question is, what is the standard of soft and hard? What do you mean soft and hard?

Soft and hard is: your mattress should be able to easily accept your body shape, balanced support your weight, so that you sleep on your side or lie on your back, the spine to maintain the most relaxed straight state.

Sounds a little convoluted? In order to facilitate understanding, you can look at the following picture, if this is the state, that is a good mattress.

If the mattress in the furniture store can't meet this, no matter how good the material it uses, no matter how luxurious it looks, no matter how heavily discounted it is, don't buy it!

The next question is, everyone's size and weight is different, so what's the fastest way to figure out if this bed will hold me?

It's easy, in one move: lie on your side.

Next, we use this position to evaluate the mattress.

For contrast, I suggest you try an experiment at home: sleep on your side on the floor. The floor is equivalent to the hardest bed, so you can feel what it feels like when the mattress is too hard.

Start the floor experiment:

After lying down, try to keep your head, neck and torso in line. You can ask a friend for help or turn on your phone's selfie camera.

You will find that there is a large gap between your head and the floor, and the shoulders and hips will gradually feel the pressure, so you can not help but start to roll over. Apparently, a mattress like the floor is too hard.

Now, you can lie on your side on the mattress you want to test sleep on.

Similarly, let your head, neck and spine form a straight line, pay attention to the gap between the head and the mattress, if the gap is obvious, up to or more than 6 cm, it means that the mattress is too hard.

Another situation is that after lying on the side, it is found that the head can contact the mattress very smoothly, but the buttocks are sunk in, just like lying on the net, indicating that the mattress is too soft.
