Side sleeping is the most common style for people to adopt. When individuals sleep this way, they usually need a surface that will not put undue pressure on the shoulders and hips. A softer mattress usually fits because it allows these pressure points to sink into the surface.
A firmer bed generally serves people who prefer to sleep on their stomachs more adequately because it helps keep their spines aligned.
Back sleepers also need a surface that will support their lower backs. These people will be happiest with mattresses of a medium firmness to ensure the correct amount of support.
Because there are many options available in mattresses with various firmness levels, it’s helpful to visit showrooms to try the different mattress styles.
