Is a firm or medium mattress better for back pain?

For most people a medium like this Beautyrest Quintessence is the better balance: at 5/10 it gives the supportive pushback that prevents hammock sag without forcing your shoulders and hips into a too-hard surface. The 1000 pocketed coils of 13.75-gauge steel keep the spine neutral at 7.1/10 support, while 5 inches of comfort foam relieve pressure at 10/10. Dedicated stomach sleepers or much heavier bodies may still want a firmer feel.
