SleepAdvisor gives all mattresses a firmness rating between one and ten, with higher numbers indicating a firmer mattress. Most people find their happy place in the middle, between four and six. However, these numbers are relatively subjective as a middle number can feel hard for some sleepers or vice versa.
Doctors say that firm mattresses are generally good picks for stomach and back sleepers, because they provide the most spinal support, since sinking too deeply into your bed may cause a misalignment after a few nights. Firm mattresses are also better for people of size, hot sleepers and those who have arthritis.
