A medium-firm mattress is similar to a mattress with medium firmness, only it’s slightly more supportive. Research has shown that mattresses labeled as being medium-firm may be associated with less lower back pain, though one mattress brand’s “medium” may be the same as “medium-firm,” or even another company’s “firm.” Again, mattress firmness is subjective and depends on how it works for your body.
