Best Extra Firm Mattresses: Orthopedic, for Back Pain, and more
Sleeping on an extra firm mattress is a nightmare for some people, but it’s a dream come true for others. Extra firm mattresses can help your back’s health as they provide a level surface for your body during sleep. This helps your body maintain good posture and prevents your back from curving.
They are sometimes referred to as Orthopaedic mattresses, and this is an excellent place to start your research if you think an extra firm mattress is right for you.

You should also take into account your preferred sleeping position when deciding on the firmness of your mattress. People who like sleeping on their back or stomach will find that an extra firm mattress will help keep their spine in its natural alignment and could be an excellent option if this is your preferred sleeping position.
Larger or heavier people sometimes benefit from sleeping on an extra firm mattress, as it provides the additional support their bodies need to be comfortable throughout the night. Extra firm mattresses are also beneficial to couples who often disrupt each other’s sleep throughout the night, as it prevents you from falling into the middle of the bed. Also, the mattress won’t bounce anywhere near as much as it would if it was soft.
