Firm Mattresses? How to Know Which Firmness Level to Choose
Posted by Monarch Bedding on August 27, 2025
Choosing the right firmness level for a mattress is one of the most important factors in ensuring a good night’s sleep and protecting the health of your spine. However, many people wonder which level is ideal: soft, medium, or firm? The answer depends on several factors: body weight, sleeping position, personal preferences, and any health issues.
What is mattress firmness?
Firmness refers to the sensation you feel when lying down on the mattress—that is, whether the mattress feels “firm” or “soft.” This characteristic depends directly on the materials used in its construction, such as foams, springs, and the density of the components.
We suggest you read the article “How to Choose the Perfect Mattress” in detail to learn a little more about the materials used in mattresses and the types of mattresses available.
It is important to distinguish between firmness and support: a mattress can be soft while still providing excellent spinal support.

How do you choose the ideal firmness for you?
Consider your body weight
Lighter people tend to prefer softer mattresses, while heavier people generally feel more comfortable on firmer mattresses that don't give in too much.
Think about your sleeping position
- Side sleepers: choose softer mattresses that help relieve pressure on the shoulders and hips;
-
Back sleepers: Choose medium-firm to firm mattresses for better support;
-
For those who sleep on their stomachs: we recommend firm mattresses, which are ideal for preventing excessive curvature of the spine during the night.
Back problems or body aches
For people with lower back pain, a medium-firm to firm mattress is generally recommended. However, it is always a good idea to consult an orthopedist or physical therapist.
So, when it comes to mattress firmness, there is no one-size-fits-all answer for choosing the ideal level of firmness. Therefore, we suggest finding a balance between comfort and support, always taking your personal characteristics and physical needs into account.
