Experts believe that a long sleep will make the spring stress uneven, which is not conducive to extending the service life of the mattress. Sleeping on one side of the mattress is easy to cause spring deformation and the mattress is sunken. If the spring of the mattress loses its elasticity, it can't provide good support for the body. People lying on it will change the normal curvature of the human spine, make the related muscles and ligaments tense, make people more tired and weak, and wake up with backache.

Mattress maintenance

In the first year of a new mattress, it is best to change the front and back and the placement direction every 2~3 months to make the mattress stress evenly, and then turn it over once every six months.

Mattress maintenance

Mattresses should also be replaced regularly. Generally speaking, the mattress springs of 8~ 10 years have entered a period of decline, and even the best mattress should be "retired".
