When it comes to choosing a mattress, firmness is one of the most important factors — yet it’s often misunderstood. Many people confuse firmness with support, but the two are not the same. At Well Sleep, we help you understand what mattress firmness really means and how to choose the best one for your body and sleep style.

What Does Mattress Firmness Mean?

Firmness refers to how soft or hard a mattress feels when you lie down on it. It affects the surface comfort and pressure relief but not necessarily the support system underneath.

Mattress firmness is usually rated on a scale of 1 to 10:

1–3: Soft

4–6: Medium

7–10: Firm

Soft Mattress (1–3)

Best for: Side sleepers, people with joint pain, or lighter individuals

Feel: Plush, deeply contouring, body-hugging

Benefits:

Excellent pressure relief on hips and shoulders

Ideal for those who prefer a “sinking in” feel

Considerations:

May lack sufficient support for back or stomach sleepers

Can cause spinal misalignment if too soft for your body weight

Medium Mattress (4–6)

Best for: Combination sleepers, couples, or those unsure of preference

Feel: Balanced contour and support

Benefits:

Offers moderate softness with good support

Accommodates most sleep positions

Ideal for couples with different firmness needs

Considerations:

May not offer enough pressure relief for some side sleepers

Might feel too soft for heavier back or stomach sleepers

Firm Mattress (7–10)

Best for: Back and stomach sleepers, heavier individuals, or those with back issues

Feel: Flat, supportive surface with minimal sinkage

Benefits:

Promotes spinal alignment for back and stomach sleepers

Helps reduce sagging for heavier body types

Considerations:

May feel too rigid for side sleepers

Less contouring around pressure points

How to Choose the Right Firmness

When choosing a mattress firmness, consider:

Your sleep position

Body weight

Health conditions (like back or joint pain)

Personal comfort preferences

At Well Sleep, our mattresses are engineered to offer tailored firmness and orthopedic support to suit every type of sleeper.

Final Thought

Firmness is a personal choice, but choosing the wrong level can affect your sleep quality, spinal health, and daily energy. Understanding how each firmness level works helps you make a confident, comfort-first decision.
