Sleeping on the wrong mattress can cause or worsen lower back pain. Lack of support from a proper mattress can lead to poor sleeping posture, overload the muscles and not help keep the spine aligned, all of which contribute to low back pain.
Sleep comfort is also sacrificed if the mattress does not match individual preferences. A mattress that provides comfort and back support helps reduce lower back pain, allowing the spinal structures to truly rest and rejuvenate throughout the night.
"What mattress is best for you to sleep on?. Although we generally tend to say that a firmer mattress tends to be better for most people, the real answer is that each person will have the best mattress for themselves.
There's nothing else to do but go to the store and try out mattresses and see which one is most comfortable for you. There's no right or wrong answer here, unless you want to sleep on a newer mattress. You know — if the mattress is really old and can't support you, that's not good. But instead, the best thing to do is go to the store and try different mattresses and see which one is best for you.
