Temperature Regulation:
Temperature regulation refers to a mattress’s ability to manage heat and moisture. Certain materials, like gel-infused memory foam or breathable natural latex, excel in this area. A 2018 study by the Journal of Sleep Research indicated that temperature control affects sleep quality. A mattress that sleeps cool may benefit those who often feel too warm at night. -

Additionally, consider any specific health issues. People with back pain often find relief on medium-firm mattresses. A mattress that is too soft may worsen discomfort for these individuals.
