Best Mattress for Low Back Pain and Backaches: 2026 Guide
Partilhar
Back pain improves, in most cases, when the mattress gives the spine the right support. It is not the only factor, but it is one of the few you can change in a single night. This guide explains which firmness to choose, what changes according to your sleeping position, and when the mattress really is the problem. I am writing it the way I usually explain it on the phone.
In short: which one to choose
Three profiles cover most cases of lower back pain. Prices are starting prices, for the smallest size of each product page.
| If you are... | Choose | Why | When not to choose this one |
|---|---|---|---|
| Someone who sleeps on the back, with lower back pain | Hisui (from 289 €) | High resilience and memory foam, firm, 26 cm. The memory foam fills the gap between the lower back and the mattress. | If you sleep on your side: too firm creates pressure at the shoulder. |
| Someone who sleeps on the side | Sora (from 309 €) | Pocket springs and high resilience, medium firmness, 20 cm. The shoulder and the hip sink enough for the spine to stay straight. | If you weigh more than 90 kg: medium firmness may not be enough. |
| Someone who weighs more than 90 kg | Samurai (from 459 €) | Pocket springs and high resilience, high firmness, 30 cm. It gives the support that a medium mattress cannot hold. | If you sleep on your side, or have not yet tried medium firmness. |
Diagnosed, persistent or intense back pain: speak first with your doctor or physiotherapist. The mattress helps with support, it does not replace clinical assessment.
This is the core guide on the subject. If your question is only about firmness, see firm or soft mattress for the back. If you wake up stiff and want to understand whether the mattress or the chair is to blame, see waking up with back pain. And if the term "orthopaedic" interests you, I explain it in orthopaedic mattress: what it is.
The right firmness: neither hard nor soft
For years the idea was sold that a very hard mattress is better for the back. The studies point the other way. A trial published in The Lancet showed that people with chronic lower back pain had less pain on a medium-firm mattress than on a very firm one.
The reason is simple. A mattress that is too hard does not follow the natural curve of the spine: the lumbar area is left without support. A mattress that is too soft lets the hip sink and throws everything out of alignment. Medium firmness, or medium-firm, is the point of balance for most people.
I say “most” on purpose. Your weight and your sleeping position change the calculation.
Your sleeping position decides half of it
If you sleep on your back
You need firm support in the lumbar area, without pressure points at the shoulders. Medium-firm works well. Memory foam helps because it fills the gap between the lower back and the mattress. The Hisui mattress was designed for this profile: high resilience plus memory foam, firm, 26 cm.
If you sleep on your side
The shoulder and the hip need to sink a little for the spine to stay straight. A mattress that is too firm creates pressure at the shoulder and you wake up with a numb arm. Here I want medium firmness with good adaptation. The Sora mattress — pocket springs plus high resilience, medium firmness — is the one I usually suggest.
If you sleep on your front
It is the position that punishes the lower back the most. If you cannot change it, choose a firmer mattress so the stomach does not sink, and a low pillow. It reduces the arch in the lumbar area.
Pocket springs, memory foam or hybrid?
The three respond differently for someone in pain.
- Pocket springs: each spring works on its own. Good zone-by-zone support and plenty of ventilation. Useful if you get hot at night or share the bed.
- Memory foam: it moulds to the body and distributes pressure. It helps with pain points and with people who sleep on their back.
- Hybrid: springs below, memory foam on top. It covers both sides. The Takumi mattress follows this logic: pocket springs, memory foam and high resilience, 26 cm, medium firmness.
If you want the technical detail, I have an article only about this: spring or memory foam mattress.
Weight matters more than people think
Someone heavier sinks further. If you are above 90 kg, a medium-firm mattress may not be enough and the lower back is left without a base. In that case I move the firmness up. The Samurai mattress — pocket springs plus high resilience, high firmness — gives the full support that a medium mattress cannot hold.
Couples with very different weights are the hardest case. There I prefer a medium-firm hybrid that forgives both sides, such as the Takumi.
You have the reference by weight bracket, with the densities in kg/m³, in the firmness by weight table.
And “orthopaedic” mattresses?
It is the question I am asked straight after the one about firmness, and the honest answer starts there: “orthopaedic” is not a medical category nor a certification. It is a commercial name the industry uses for firm-support mattresses. No organisation awards it, and for that reason it is not in itself a guarantee of anything — I explain the subject in full in the orthopaedic mattress guide.
That said, the range exists and makes sense for those who genuinely need firm support. At Dreamura there are two: the Sumo and the Sumo Plus, both high firmness. They are the choice of someone who has already tried medium firmness and still wakes up with the lower back unsupported — typically someone who sleeps on their back, with above-average weight, or someone coming from a badly sagging mattress who wants the opposite extreme.
I do not recommend them by default. A mattress that is too firm creates pressure at the shoulders and the hips, above all for those who sleep on their side, and that is exactly the mistake the Lancet trial points to. The right order is to start with medium or medium-firm and only move up if it is not enough.
Sometimes the problem is simply the age of the mattress
A mattress loses support over time. If yours is more than 8 to 10 years old, or already sags in the middle, replacing it with a new medium-firm one resolves a great deal of pain on its own — this has been studied. Before assuming that you need the “firmest mattress on the market”, ask yourself how long you have had the current one.
There is a thirty-second test you can do now: take off the sheets, get down to eye level with the surface of the mattress and look along its length. If the line is curved instead of straight, the core has given way — and in that case not even a topper will solve it.
How to test without risk
Firmness is felt after two or three weeks, not on the first night. The body needs to adjust. That is why every Dreamura mattress comes with 100 nights of testing at home. If at the end of that time the back has not improved, you return it at no cost.
They are made in Portugal, with a 10-year warranty. Delivery is free on the mainland, within 5 working days.

Frequently asked questions
What is the ideal mattress firmness for lower back pain?
Medium or medium-firm, for most people. A trial published in The Lancet showed that people with chronic lower back pain had less pain on a medium-firm mattress than on a very firm one. Weight and sleeping position adjust that reference: above 90 kg the firmness goes up, and those who sleep on their side need the shoulder and the hip to sink a little.
Is a hard mattress better for back pain?
No. It is the most common idea and the evidence points the other way. A mattress that is too hard does not follow the natural curve of the spine and leaves the lumbar area without support, which keeps the tension through the whole night. The opposite extreme does not work either: a very soft mattress lets the hip sink and takes the spine out of alignment.
Which mattress should I choose if I sleep on my side and have lower back pain?
Medium firmness with good adaptation to the body. Sleeping on the side, the shoulder and the hip have to sink enough for the spine to stay straight; a mattress that is too firm creates pressure at the shoulder and makes you wake up with a numb arm. In the Dreamura range, the Sora — pocket springs with high resilience, medium firmness — is the one indicated for this profile.
Which mattress should I choose if I sleep on my back and have lower back pain?
Medium-firm, with a layer that fills the gap between the lower back and the mattress. Memory foam does that job well because it moulds to the curve. The Hisui was designed for this profile: high resilience with memory foam, firm, 26 cm in height.
Which mattress should I choose if I weigh more than 90 kg?
The firmness goes up. Someone heavier sinks further, and on a medium-firm mattress the lower back can be left without a base. The choice becomes a high-firmness mattress with a good support structure, such as the Samurai. In a couple with very different weights, a medium-firm hybrid such as the Takumi usually serves both sides better than two extremes.
Does an orthopaedic mattress solve lower back pain?
Not because it is orthopaedic. “Orthopaedic” is not a medical category nor a certification — it is a commercial name for firm-support mattresses, and no organisation awards it. It makes sense for someone who has already tried medium firmness and still wakes up with the lower back unsupported, typically someone who sleeps on their back or is above average weight. For those who sleep on their side, it is usually too firm.
How long does it take to feel a difference on a new mattress?
Two to three weeks. Firmness is not assessed on the first night, because the body comes used to the previous mattress and needs to readjust. That is why it makes a difference to buy with a testing period at home — at Dreamura it is 100 nights, with a return at no cost.
How do I know whether the pain comes from the mattress or from its age?
There is a thirty-second test: take off the sheets, get down to eye level with the surface of the mattress and look along its length. If the line is curved instead of straight, the core has given way. Above 8 to 10 years of use, the loss of support is common and replacing it with a new medium-firm mattress resolves a great deal of pain on its own.
Does a topper solve it, or do I have to change the mattress?
It depends on what is wrong. A topper corrects a mattress that is too firm, adding softness on top. It does not correct a sagging mattress nor a mattress that is too soft, because the problem is in the core and no surface layer gives support back. If the line of the mattress is already curved, the topper only postpones the change.

One last note
If you are in doubt between two, start with the less firm one: it is easier to compensate with a topper than with a mattress that is too hard. And if you would like to talk, I will call you. It is 10 minutes on the phone — you can book here.
Note: persistent or intense back pain should be seen by a doctor. A mattress helps with support and with sleep, but it does not replace clinical assessment.
