How firm should your mattress be?
Ultimately, you want a mattress that keeps your spine aligned and relieves pressure.
Studies suggest medium-firm proves most beneficial
- A major 2003 study in The Lancet highlighted the benefits of medium-firm for those who suffered from chronic lower back pain.
- A 2025 study out of Beijing, China, suggested that medium-firm proved best for the 12 average-weight participants.
The researchers monitored their sleep quality and quantity using an electroencephalogram (EEG), where sensors measure the brain’s electrical activity.
- Too firm resulted in: pressure points in shoulders, hips and knees.
- Too soft resulted in: an unnatural curvature of the spine.
In the end, medium proved to be the best fit for a restful night's sleep.

It also comes recommended by an expert in the treatment of spinal and musculoskeletal conditions, Dr Mark Craig (The Back Doctor).
Craig says his own back pain “improved significantly” having owned this mattress and he now recommends it to his patients as “part of a multi-modal treatment for back and neck pain”.
