Mattress Firmness Levels: How to Choose the Right One for Your Sleep Style

When shopping for a new mattress, understanding firmness levels is crucial to ensuring a good night's sleep. Here's a short yet comprehensive guide to help you choose the right mattress firmness for your sleep style, with a recommendation for the Sonno mattress, known for its balanced support and comfort.

What Are Mattress Firmness Levels?

Mattress firmness levels range from very soft to very firm, typically rated on a scale from 1 to 10:

  • 1-2: Very Soft – Ideal for lightweight sleepers who prefer to sink deeply into their mattress.
  • 3-4: Soft – Suitable for side sleepers needing pressure relief on shoulders and hips.
  • 5-6: Medium – Best for combination sleepers who change positions frequently.
  • 7-8: Firm – Good for back sleepers requiring support for spinal alignment.
  • 9-10: Very Firm – Preferred by stomach sleepers who need minimal sinkage to keep their spine aligned.

Choosing the Right Firmness for Your Sleep Style

  1. Side Sleepers: Often benefit from a softer mattress (3-4) to cushion the shoulders and hips.
  2. Back Sleepers: Generally prefer medium to firm mattresses (5-7) for optimal support and spine alignment.
  3. Stomach Sleepers: Need a firmer mattress (7-9) to prevent the lower back from sagging.
  4. Combination Sleepers: A medium mattress (5-6) offers versatility for various sleeping positions.
