Why Side Sleepers Need Different Support

Side sleeping creates pressure points that require cushioning.

Key Points:

  • Pressure builds on shoulders and hips
  • Cushioning reduces discomfort
  • Alignment must be maintained
  • Surface feel matters more for this position

Pressure Relief and Comfort

Pressure relief is the most important factor for side sleepers.

Key Points:

  • Contour reduces pressure points
  • Foam excels at pressure relief
  • Too firm creates discomfort
  • Balance between sink and support

Best Firmness for Side Sleepers

Softer mattresses typically work best.

Key Points:

  • Soft to medium (5–6/10)
  • Allows shoulder and hip sinkage
  • Prevents pressure build-up
  • Supports natural alignment

Materials to Consider

Material affects how pressure relief is delivered.

Key Points:

  • Memory foam provides deep contouring
  • Hybrid offers balanced feel
  • Latex gives responsive cushioning
  • Material choice affects feel and airflow

Common Mistakes

Incorrect firmness is the most common issue.

Key Points:

  • Choosing mattresses that are too firm
  • Ignoring pressure points
  • Not considering body weight
  • Overlooking material differences

Choosing the Right Mattress for You

Side sleepers should prioritise pressure relief with softer mattresses that maintain alignment.
