The Ultimate Mattress Firmness Guide – Find the Right Comfort Level for Your Sleep Style

The Ultimate Mattress Firmness Guide – Find the Right Comfort Level for Your Sleep Style

When shopping for a new mattress, one of the most important — and often confusing — decisions is firmness. Too soft, and you might sink and wake up sore. Too firm, and pressure points can build in your shoulders or hips.

But how do you know what’s right for you?

This guide walks you through everything you need to know to find your ideal firmness — and how Snoozel Green’s organic latex mattress delivers the perfect balance for most sleep styles.

What Is Mattress Firmness?

Firmness refers to how much a mattress resists pressure — or how it feels when you lie on it. It’s often rated on a scale from 1 (very soft) to 10 (very firm). Most sleepers fall between a medium (5-6) and medium-firm (6.5-7.5) preference.

It’s not the same as support, which is about keeping your spine aligned. A soft mattress can be supportive if it contours well, and a firm one can lack support if it doesn’t respond to pressure points.

Best Firmness by Sleep Position

Side Sleepers

  • Need: Pressure relief at shoulders and hips

  • Ideal firmness: Soft to medium (4–6)

  • Why: Too firm, and your joints may feel compressed overnight

Back Sleepers

  • Need: Spinal alignment and lower back support

  • Ideal firmness: Medium to medium-firm (6–7.5)

  • Why: Too soft, and your hips may sink out of alignment

Stomach Sleepers

  • Need: A firm surface to keep hips from dipping

  • Ideal firmness: Firm (7–9)

  • Why: Softer mattresses can lead to back pain and strain

Combination Sleepers

  • Need: Responsiveness and adaptability

  • Ideal firmness: Medium-firm (6.5–7)

  • Why: You need comfort and support in multiple positions

How Body Weight Affects Firmness Preference

Heavier sleepers (over 90kg) may prefer firmer mattresses to avoid sinking too deeply. Lightweight sleepers (under 60kg) might prefer a softer feel for better contouring.

That’s why mattress choice isn’t just about sleep position — it’s about your individual build and how much pressure you apply to the surface.

How Snoozel Green Gets It Right

Our organic mattress is designed with a medium-firm feel that suits most sleep styles and body types. Why?

  • Responsive organic latex provides gentle contouring without sagging

  • Zoned support offers the right give where you need it

  • Breathable materials keep you cool and comfortable all night long

And because it’s handcrafted from GOLS-certified latex, GOTS-certified cotton, and organic wool, it’s free from the foams and glues that degrade support over time.

Still Not Sure?

We offer a 100-night sleep trial so you can test it in your own home. If it’s not the right firmness for you, we’ll take it back — no questions asked.

Final Thoughts

Choosing the right firmness can be the difference between waking refreshed or waking stiff. Use your sleep position and body weight as a guide — then try it for yourself.
