Because the needs and preferences of each person differ, the right mattress is not the same for everyone.
The mattress should generally help align and support the spine and it should help support the head and absorb the pressure of the leg and pelvic muscles.
A good mattress must also support and relieve the pressure from the neck to help achieve proper blood circulation.
It should be comfortable and support the whole body. However, a good mattress is one that will work best for your body type.
Semi-hard mattresses are usually for those who sleep on their stomach, while a soft mattress helps younger people sleep on the side.
