Do you wake up stiffer in the morning than when you went to bed? That’s rarely down to age and often down to your mattress. A worn-out or overly soft surface forces your spine into an unnatural curve that your muscles have to compensate for all night long. The result: tension, back pain, poor sleep.
This guide tells you what really matters in a mattress for back pain. No marketing clichés, and no claim to replace a medical diagnosis.
How your mattress affects your back
When you lie down, your spine should keep the same natural double-S shape as when you stand. A mattress that is too firm pushes your shoulders and hips upwards; one that is too soft lets your pelvis sag. Over hours, both have the same effect: your back muscles compensate instead of recovering.
A good mattress for back pain does three jobs at once:
- Relieve pressure points, especially at the shoulders and hips
- Keep the spine straight with ergonomically adapted support zones
- Adapt to sleeping position and body weight. What’s right for you may be wrong for your partner
The 3 most common mattress mistakes with back pain
1. “The firmer, the better.” Wrong.
A widespread myth. A mattress that is too firm doesn’t relieve your shoulder enough, so you’ll change position more often during the night and still wake up tense. The right firmness depends on your weight, your sleeping position and your personal preference.
2. “My old mattress will do.”
Mattresses lose their support over the years. After 8 to 10 years at the latest, the material of a mattress is worn out. If you can see indentations or lying on it feels hard and uneven, the mattress is the most likely cause of your back pain.
3. Slatted bed base and mattress don’t match.
A 7-zone mattress on a rigid, unadapted slatted bed base loses its effect. The two have to be matched to each other. Our slatted bed bases are designed precisely for BeSports mattresses.
Which firmness level for which complaint?
The following table is a guideline, not a law of nature. If you’re sensitive, you’ll often be better off one firmness level softer than the table suggests.
| Body weight | Recommended firmness level |
|---|---|
| up to 60 kg | H1 to H2 (soft to medium-soft) |
| 60 to 80 kg | H2 to H3 (medium-soft to medium-firm) |
| 80 to 100 kg | H3 to H4 (medium-firm to firm) |
| over 100 kg | H4 to H5 (firm to very firm) |
With acute back pain, a mattress with two firmness levels is often worth it. You can switch sides depending on how you feel that day. That’s exactly what you get with the HERO mattress.
Why 7-zone mattresses are ergonomic
A 7-zone mattress is not divided into 7 equally firm areas – quite the opposite. The shoulder and hip areas are softer so that these wider parts of the body can sink in deeper. The lumbar and knee areas are firmer to support the spine.
The result: your spine stays straight whether you sleep on your side or your back, without you having to consciously control it. More on this in our detailed article 7-zone mattress: pros and cons.
Sleeping position and the right mattress
Side sleepers
Need a mattress that gives way in the shoulder and hip area. Mattresses that are too firm lead to pain in the shoulder and arm because blood flow is restricted. Recommendation: a cold foam mattress with a pronounced shoulder zone.
Back sleepers
Benefit from medium firmness and pronounced lumbar support. A mattress that is too soft lets the pelvis sag; one that is too firm leaves a gap under the lower back.
Stomach sleepers
Tend to need firmer mattresses so that the pelvis doesn’t sink in too deeply and cause a hollow back. Stomach sleepers should also make sure they use a flat pillow.
When to see a doctor, when to get a new mattress?
If your back pain lasts longer than two weeks, radiates into your leg or arm, or is accompanied by numbness, you should see a doctor. No mattress replaces a diagnosis.
With dull morning tension that improves over the course of the day, it’s worth checking your mattress first. An ergonomic 7-zone mattress with the right firmness can often improve the problem significantly within a few weeks.
Try it risk-free instead of buying blind
You can try every BeSports mattress at home with a 100-night sleep trial. Lying on a mattress for 5 minutes in a furniture store is no basis for a decision that will stay with you for the next 8 years. Take a relaxed look at our mattress range and ask us if you’re unsure about the firmness level or material.
