I bought a Yuan Lixin healthy mattress last month, and it feels good. I used to sleep badly. Now I lie on Yuan Lixin's healthy mattress and sleep till dawn. After getting up, the whole person is quite relaxed, and the mental state during the day is also good. I found that I was tired and lazy before. As for the other effects of mattress promotion, I haven't been to the hospital for examination, and it's still unclear, but the effect on improving sleep really surprises me.
