Does Mattress Firmness Affect Back Pain? What the Evidence Says
In a large randomised trial, people with chronic low-back pain who slept on medium-firm mattresses reported less pain than those on firm ones. Reviews conclude medium-firm is a reasonable starting point but that evidence is limited and individual preference matters. Persistent back pain needs a doctor.
The trial
A Lancet trial of 313 adults with chronic non-specific low-back pain compared firm and medium-firm mattresses; the medium-firm group had better outcomes on pain in bed and on rising and on disability.
The reviews
A systematic review of controlled trials found medium-firm surfaces generally favoured for comfort, sleep quality and spinal alignment, while noting small studies and varied methods. A smaller study reported improved back pain and sleep quality after people changed to new bedding systems.
Practical meaning
Do not choose the firmest mattress. Choose medium-firm as a start, adjust for your position and weight, and use a trial period.
Frequently asked questions
Is an orthopaedic mattress better?
The word is not regulated; look at construction and firmness.
Will a new mattress cure my back pain?
No. It may improve comfort, but persistent pain needs medical advice.
