Best mattress for back pain
A mattress can stop making back pain worse. It is not a treatment, and anything sold as one is overreaching.

Read this first
Back pain has many causes and a mattress addresses one of them: whether your spine is held in a reasonable position for eight hours. That is worth getting right and it is not medical care.
See a GP or physiotherapist if pain is severe, persistent, worsening, follows an injury, or comes with numbness, weakness, unexplained weight loss, fever, or any change in bladder or bowel control. Those need assessment rather than bedding.
What a mattress does is hold your spine roughly where it sits when you stand. Too soft and the hips sink and the lower back arches or sags. Too firm and the shoulder and hip cannot sink, so the spine bends the other way and pressure concentrates.
The research that exists broadly points at medium-firm for most people, and the more useful framing is that the right firmness depends on your weight and the position you sleep in.
The picks
The pick, if you want one answer
Emma Original Lite Mattress, 7.3 / 10. Zoned support at budget money, which is the construction that most directly addresses spinal alignment.
| Product | Best for | From | Score |
|---|---|---|---|
| Emma Original Lite Mattress | Best value zoned support | £199 | 7.3 / 10 |
| Silentnight Sofia 1200 Mirapocket | Best medium-firm | Mid range | 7.2 / 10 |
| Rem-Fit 4000 Ortho Elite Hybrid Mattress | Best if you have been told to sleep firm | Mid range | 7.6 / 10 |
| Origin Hybrid Pro Mattress | Best all-round specification | £374 | 8.4 / 10 |
Emma Original Lite Mattress: Best value zoned support
£199 · 7.3 / 10
A three-zone pocket spring layer at £199. Zoning varies spring gauge along the mattress, firmer under the lumbar and more giving under shoulder and hip, which is the most direct answer to keeping a spine level. It is the cheapest zoned mattress I know of in Britain.
Buy it if
You want the right construction for alignment without spending much.
Do not buy it if
You are over about fifteen stone. There is limited support headroom here.

Silentnight Sofia 1200 Mirapocket: Best medium-firm
Mid range · 7.2 / 10
Zoned 1,200 pocket springs from a manufacturer trading since 1946, with a 60 night comfort exchange buying direct. That last point matters more here than anywhere: if you are buying for back pain you may not know what firmness suits you, and an exchange lets you correct it rather than only return.
Buy it if
You want medium-firm zoned support and the option to change firmness if you get it wrong.
Do not buy it if
You are heavier than about sixteen stone.

Rem-Fit 4000 Ortho Elite Hybrid Mattress: Best if you have been told to sleep firm
Mid range · 7.6 / 10
Nine out of ten for support here. If firm is genuinely what you need rather than what you assume, this is one of very few UK mattresses that delivers it with enough spring count that regions still respond independently. Firmness without gradation is a plank.
Buy it if
A clinician has advised firm, or you are heavier and sinking through your current mattress.
Do not buy it if
You are a lighter side sleeper. Firm compresses the shoulder and can create new problems.

Origin Hybrid Pro Mattress: Best all-round specification
£374 · 8.4 / 10
The highest scoring mattress on this site at 8.4, and the reason is construction per pound rather than any single feature. For most people with ordinary lower back ache from an ageing mattress, this is the sensible replacement.
Buy it if
You want the strongest general specification at a sensible price.
Do not buy it if
You need a very deep mattress for a heavier build.

What firmness, for your body and position
There is no single answer, and the two variables are your weight and your sleeping position.
| Position | Aim for | Adjust |
|---|---|---|
| Side | 4 to 6 | Softer under 10 stone, firmer plus depth over 15 |
| Back | 6 to 8 | The lumbar gap needs filling, not bridging |
| Front | 7 to 9 | If the hips sink, the lower back arches all night |
A stated firmness is not absolute. A mattress compresses until its resistance matches your weight, so under ten stone a rated 7 feels firmer than 7, and over fifteen stone it feels softer and gives less support than the number implies.
Where you ache tells you which way you are wrong
This is the most useful diagnostic on the page and it costs nothing.
| What you notice | Usually means |
|---|---|
| Lower back ache on waking that eases once you move | Mattress too soft. The hips have been sinking all night. |
| Hip or shoulder pain, side sleeping | Mattress too firm. Pressure is concentrating where you are widest. |
| Ache at the back of the neck | Pillow too high, not the mattress. |
| Numb arm, side sleeping | Pillow too low, or mattress too firm at the shoulder. |
| Pain worse after standing, better lying down | Not a mattress pattern. Worth raising with a clinician. |
Four things to rule out before buying anything
1. Your pillow. A great deal of pain blamed on a mattress is a pillow at the wrong height. Lie in your sleeping position for ten minutes and have someone look at you from behind: your neck should be a straight continuation of your spine. Free.
2. Your base. Slats more than about 7.5 centimetres apart let a mattress sag between them, which creates exactly the dip that causes the problem, and voids most guarantees. Measure them. A sheet of plywood is a few pounds.
3. A dip in the mattress you already have. Lay a straight edge across it and measure the deepest gap. More than about 25 millimetres and the mattress is done; under that and a topper may be all you need.
4. Your knees, if you sleep on your side. An unsupported top leg falls forward and rotates the pelvis, twisting the spine all night. Fold a spare duvet between your knees for a week. If it helps, a body pillow helps more. Some side sleepers get more relief from this than from a new mattress.
What to expect after switching
A new mattress feels different for about a fortnight, partly because it is settling and partly because your body has adapted to whatever you slept on before. The first two nights tell you almost nothing, and a short-term increase in stiffness while you adjust is common.
That is why a genuine sleep trial matters more here than a discount. Nectar's 365 nights and Silentnight's 60 night comfort exchange both apply buying direct, and an exchange is more useful than a return when you are unsure of firmness.
What not to buy for back pain
Anything sold as orthopaedic on the strength of the word. It is not a regulated term. Any manufacturer can apply it to anything firm. Ask for the spring count and the firmness.
The firmest mattress you can find. This is the most common overcorrection. Too firm concentrates pressure at the shoulder and hip and creates a different problem, particularly for side sleepers.
A very high spring count, expecting more support. Above about 2,000 in a king, counts rise using thinner wire. You gain contouring, you lose individual spring strength.
A topper to fix a mattress that has dipped. It will follow the dip within weeks.
Anything marketed as therapeutic or medically approved. Mattresses are bedding. If pain is severe, persistent or worsening, that belongs with a clinician rather than a purchase.
Also considered, and why they are not here
A roundup is only as useful as what it leaves out, so here is what was assessed and rejected for this list.
| Product | Why it is not on the list |
|---|---|
| Otty Extra Firm | Excellent for heavier sleepers and too firm as a general back pain recommendation. Over-firming is the most common mistake people make here. |
| Ergoflex 5G | Outstanding motion isolation and a company trading since 2006, and all-foam does not zone and runs warm. Better for couples than for alignment. |
| Mlily Memory Gel 500 | No springs despite the number, and no published foam density. Not a construction to buy when alignment is the problem. |
| Inofia Cloud-Lux | A pillow-top, which adds softness through a quilted layer that compresses faster than the core beneath it. The wrong direction if your hips are already sinking. |
| Purple | The coolest surface on this site and an unusual feel that divides people. Buy it for heat, not for back pain. |
How this list is made, and who made it
Independence
No brand pays to appear on this site and no placement is sold. Some links earn a commission if you buy, which never changes a score, an order or a verdict. Several of the lowest scores here are on products that carry commission, and several recommendations carry none.
Who writes this. Kyle Klinkradt has worked in the mattress and bedding industry for over ten years across retail, distribution and brand partnerships, and has handled, sold or assessed products from every major UK bed-in-a-box brand. Every review on this site is written by one person, so the scores mean the same thing from page to page.
What the assessment is. Construction specifications against what they physically do: spring height and where in the mattress it sits, spring count for the size, gauge, whether the base is sprung or foam, foam density where it is published, comfort layer depth and material. Then the commercial terms that decide what you are actually buying: trial against returns policy, guarantee length against the company's UK trading history at Companies House, and the regulatory record.
What it is not. This is not a laboratory. I do not publish pressure-mapping data or claim to have slept eight years on every mattress here, because nobody has and pages that imply otherwise are not telling you the truth. Where a judgement rests on construction rather than long-term use, the review says so.
What gets a product removed. Leaving the UK market, a specification change that makes the review inaccurate, or a corrected fact. Brands that have withdrawn are kept on the site with the score removed rather than quietly deleted, because people still search for them.
See editorial independence, corrections and the author page.
How these were chosen
Every product here has its own review on this site with a score out of 10, and the score is a judgement rather than an average. Nothing appears in a list because it pays more.
A score is against the market, not against its own range. The cheapest mattress in a lineup is usually priced to make the model above it look reasonable, and the flagship of a budget range has risen into a bracket where better brands compete. Both are judged against what else you could buy for the money.
Everything listed can actually be bought in the UK. That is not a given: Casper withdrew in July 2020 and Leesa no longer sells here, and both still appear in current British roundups with affiliate links attached.
I do not pad the list. Where only three or four products genuinely qualify, there are three or four. A list of seven when the category contains four good ones is a list with three bad recommendations in it.
Prices move constantly. Judge the cash price on the day rather than any percentage beside it. See every review on this site or where the real savings are.
Questions people ask
What mattress firmness is best for back pain?
Medium-firm suits most people, and the useful version depends on position and weight. Side sleepers 4 to 6, back sleepers 6 to 8, front sleepers 7 to 9, softer under ten stone and firmer with more depth over fifteen.
Can a mattress cause back pain?
It can contribute. Too soft lets the hips sink so the lower back sags, and too firm stops the shoulder and hip sinking so pressure concentrates. Lower back ache on waking that eases once you move usually points to too soft.
Should I buy a firm mattress for back pain?
Not automatically, and over-firming is the most common mistake. Too firm concentrates pressure at the shoulder and hip, particularly for side sleepers. If a clinician has advised firm, take that from them rather than from a product name.
What should I check before buying a mattress for back pain?
Your pillow height, your slat spacing, whether your current mattress has a dip over about 25mm, and if you sleep on your side, whether a pillow between the knees helps. All four are free and all four are common causes.
