How to Choose a Mattress by Sleeping Position
The best mattress depends on how you sleep and how much you weigh. This guide matches sleeping position to firmness, then covers materials, trial periods and returns.
Firmness by sleeping position
- Side sleepers: usually do better on a medium-soft to medium mattress that lets the shoulders and hips sink in slightly so the spine stays straight.
- Back sleepers: often prefer medium to medium-firm, which supports the lower back without pushing it up.
- Stomach sleepers: generally need a firmer surface so the hips do not sink too far.
- Combination sleepers: a medium feel with responsive foam or springs makes it easier to change position.
Body weight changes the equation
Lighter sleepers sink less, so a mattress can feel firmer to them than the label suggests. Heavier sleepers sink more and usually do better with a firmer, thicker mattress with strong support layers.
Mattress types
- Memory foam: contours closely and absorbs motion, but can sleep warm.
- Pocket spring: bouncy and breathable, with good edge support.
- Hybrid: springs with foam or latex comfort layers; a balance of support and pressure relief.
- Latex: responsive and durable, often more expensive.
Size and fit
Measure your bed frame and room, and check the sizing standard of the store: UK and US sizes are different. A mattress that is larger than your sleeping needs only helps if you share the bed or have pets.
Trial period, warranty and returns
- Check whether there is a trial period and how many nights it covers.
- Find out who pays for return shipping, and whether a returned mattress must be in good condition.
- Read the warranty for what counts as damage, such as the depth of body impressions.
