Why Does Mattress Firmness Matter? A firm mattress relieves pain and promotes restful sleep after a long day. Firm mattresses support your spine and joints, fit most sleeping positions, and are comfortable.

How do I know what firmness of mattress I need? The best mattress depends on your weight, sleeping position, and preference. Heavy sleepers need a firmer bed, while lighter prefer a softer one. Back and stomach sleepers prefer harder mattresses, while side sleepers prefer softer ones.

We will walk you through a mattress firmness guide for Understanding the Mattress Firmness Scale, from extra soft to extra firm, to help you choose your mattress firmness.

What is Mattress Firmness?

The firmness of mattress means how soft or firm it feels to lie on. Support is the ability of the bed to maintain your spine’s alignment, prevent pressure spots, and support your body.

Finding the right mattress firmness guide is essential for ensuring your spine stays properly aligned, reducing aches and pains, and allowing you to sleep soundly through the night.

To begin with, let us talk about how soft, medium, and firm mattresses feel.


Extra soft or soft mattresses offer a luxurious feel and little pushback, rated 1 through 3 on a mattress firmness scale. Softer mattresses are generally preferred by strict side sleepers or those needing extra shoulders, hips, and lower back comfort.


A medium mattress firmness typically falls in the middle (5) of the firmness scale (1-10), offering a balanced level of support and comfort.

It suits a wide range of sleepers by providing adequate cushioning without sinking too deeply. This level often caters to both back and side sleepers, promoting spinal alignment and pressure relief.


A firm mattress has less given and is stiffer to the touch. When you put pressure on a softer mattress, it will give way more easily. Being aware that mattress feel isn’t just two groups is essential. It’s more of a range. This could be good or bad because it means many options exist.

On a scale from 9 to 10, the firmest beds give you the most support, the least amount of sinkage, and the least amount of curves or cushioning. Some people find it hard to sleep on them, but people who sleep on their backs or stomachs usually find them very comfy.
