Firmer Mattresses May Not Help Back Pain

Goldilocks may have been onto something. When choosing a mattress, a new study says, go for one that is not too hard, not too soft, but just right.

For years, many people with back pain have thought that a hard mattress is best for their back. But a new study now shows that firmer does not mean better.

The research, published in this week's issue of The Lancet, examined 313 people who suffer with chronic back pain and morning achiness. They were given new spring mattresses that were either "firm" or "medium-firm," but were not told which type they had.
