How to choose a mattress for back painMattresses
This is a personal thing that depends on the cause of your back pain. My personal opinion is that you need a firm mattress if you have back pain, certainly if my back is very bad and the muscles have gone into spasm from overexertion the only comfortable place to be is lying on the floor. Regular exercise is beneficial, regular walks, combined with Sit-ups.
Where there is a curving of the spine, you need a softer mattress.
