How do you choose the right firmness for a box spring mattress?
You can determine the right firmness for your box spring mattress by considering your sleeping position, any back issues you may have, and your personal comfort preferences. Test different firmness levels by lying on each one for at least 15 minutes and pay attention to how your spine is supported. A good mattress feels firm yet comfortable and ensures that your back remains in a natural alignment.
Why is the right firmness of your box spring mattress so important?
The firmness of your box spring mattress directly affects how well you sleep and how you feel in the morning. A mattress with the right firmness provides optimal support for your spine and allows your muscles to fully relax during the night.
If your mattress is too soft, your body sinks in too deeply. This disrupts the natural curve of your spine and can lead to sore muscles and joints. You’ll find yourself tossing and turning more often as your body subconsciously searches for a more comfortable position.
A mattress that’s too firm causes the opposite problem. It doesn’t contour to your body properly, creating pressure points on your hips and shoulders. This restricts blood circulation and leads to a restless night’s sleep.
The consequences of choosing the wrong firmness aren’t limited to nighttime. Poor sleep quality leads to daytime fatigue, reduced concentration, and can even weaken your immune system. Back pain caused by an unsuitable mattress can persist for months, even after you’ve switched to a better one.
How do you know if a mattress is too soft or too firm for you?
Your body sends clear signals when your box spring mattress isn’t the right firmness. Watch out for these warning signs that indicate your mattress isn’t suitable for your sleep comfort.
If your mattress is too soft, you often experience:
- Lower back pain caused by a sagging spine
- Having trouble turning over because you sink into the mattress
- The feeling of being “stuck” in your mattress
- Stiffness in your neck and shoulders caused by poor support
You can tell if a mattress is too firm by:
- Painful pressure points on your hips and shoulders
- Tingling in the arms or legs due to poor blood circulation
- The feeling that you're lying "on" the mattress instead of in it
- Frequent movements during sleep
You can easily test this by sliding your hand under your lower back while lying on your back. If the firmness is just right, your hand will fit underneath it. If there’s a lot of space, the mattress is too firm. If you can’t fit your hand underneath, the mattress is too soft.
What factors determine which water hardness is best for you?
Several personal factors determine which mattress firmness is right for you. The most important factor is your preferred sleeping position, because each position requires different support.
People who sleep on their backs usually benefit from a medium-firm to firm mattress. This level of firmness prevents your lower back from sinking and keeps your spine aligned. A mattress that is too soft causes your pelvis to sink too deeply, which puts strain on your back muscles.
Side sleepers are better off choosing a soft to medium-firm mattress. Your hips and shoulders should be able to sink in to avoid pressure points, while your waist receives adequate support. This ensures that your spine maintains its natural S-shape.
People who sleep on their stomachs actually need a firmer mattress to prevent their pelvis from sinking too deeply. This can cause a hollow back and lead to back pain.
| Sleeping position | Recommended hardness. | Reason |
|---|---|---|
| Back sleeper | Medium-hard to hard | Prevents the lower back from sagging |
| Side sleeper | Soft to medium-hard | Contouring for the hips and shoulders |
| Stomach sleeper | Hard | Prevents a hollow back |
| Combi-sleeper | Medium-hard | A compromise for all positions |
Existing back problems also play a role. A firmer mattress often helps with lower back pain, while a softer mattress with good contouring works better for neck pain. Personal preferences remain important—some people simply sleep better on a soft mattress, regardless of their sleeping position.
How do you check if a box spring mattress has the right firmness?
Testing a box spring mattress requires more than just a quick five-minute check. Allow at least 15 to 20 minutes per mattress to get an accurate sense of its comfort and support.
Start by lying down in your favorite sleeping position. Notice how your body is supported and whether any pressure points develop. Try out different positions, even if you don’t normally sleep that way. This will give you a more complete picture of the mattress’s performance.
When trying out a mattress, keep these important points in mind:
- Does your spine stay in a natural alignment?
- Do you feel immediate pressure on certain parts of your body?
- Can you easily change positions?
- Does the support feel even across your entire body?
Also test the edge support by sitting on the edge of the bed. A good box spring mattress remains stable and doesn’t sag too much at the sides. This is important for getting in and out of bed and increases the usable sleeping surface.
Take your time and don’t rush. A good sleep specialist understands that choosing the right mattress firmness is a process that shouldn’t be rushed. Compare different options side by side and take notes as you test multiple mattresses.

Top service!
About four years ago, I bought a beautiful bed at Broring, Gelderlandplein. Stephan helped me.
I lived nearby.
Now that I've moved in with my partner and live in Bloemendaal, I was having problems with the bed's controls.
My boyfriend contacted Broring about this many times by phone and email. When that didn't work, Stephan came by to fix it!
We thought that was great service because I no longer live in Buitenveldert, so I'm not next door!
I was also helped in the store by a somewhat older person, blond/gray hair, glasses, who was always very friendly!
The quality of the items, including sheets, towels, etc. in the store is also very good.
