The softness and hardness of a mattress have a very important impact on maintaining spinal health. Undoubtedly, a mattress material that is too hard or too soft is not acceptable. The question is, what is the standard for softness and hardness, and what is moderate softness and hardness? Moderate softness and hardness means that your mattress should be able to easily accept your body shape, balance your weight, and keep your spine relaxed and straight when sleeping on your side or lying flat.

If the mattress in the store cannot meet this requirement, no matter how good the material is used, how luxurious it looks, or how aggressively it is discounted, don't buy it. The next question is, everyone's body size and weight are different, how can you quickly determine if this bed can hold me? It's simple, just one action to do it, lying on your side.

To achieve a comparative effect, it is recommended to conduct an experiment at home and sleep on your side on the floor, which is equivalent to a hard bed. This way, you can feel the feeling of a household mattress being too hard.

After lying down, try to keep your head, neck, and torso in a straight line. You can ask a friend to help you reference, or you can turn on your phone's selfie camera. You will find a large gap between your head and the floor, and gradually feel pressure on your shoulders and buttocks. As a result, you can't help but roll over. Obviously, the floor mattress is too hard.

Now, you can lie in a lateral position on the mattress you want to try sleeping on. Similarly, make your head, neck, and spine form a straight line, and pay attention to the gap between the head and the mattress. If the gap is obvious, reaching or exceeding 6cm, it indicates that the mattress is too hard. Another situation is that after lying on the side, you can find that your head can smoothly contact the mattress, but your buttocks have sunk in, Just like lying on a net pocket, it indicates that this mattress is too soft.

Draw a key point, a good mattress can adjust the strength of the support according to the pressure of different parts of your body, so that your head, neck, and lower spine are in a natural straight state.
