Best mattress for sciatica
Sciatica is a symptom with several possible causes, and a mattress addresses one narrow part of it.

See a clinician first
Sciatica describes pain travelling along the sciatic nerve, usually from the lower back through the buttock and down the leg. It has several possible causes and it needs assessment rather than a purchase.
Seek medical help urgently if you have numbness around the genitals or buttocks, difficulty passing urine or loss of control of bladder or bowel, or weakness in both legs. Those are emergency symptoms.
Otherwise see a GP or physiotherapist, particularly if pain is severe, persistent or worsening. The NHS website is a reliable starting point.
What a mattress can do is stop making it worse: hold your spine in a reasonable position for eight hours rather than an aggravating one. That is worth getting right and it is not treatment.
The starting point for most people is medium-firm, adjusted for weight and sleeping position.
The picks
The pick, if you want one answer
Silentnight Sofia 1200 Mirapocket, 7.2 / 10. Zoned support at budget money, which is the construction that most directly addresses keeping the spine level.
| Product | Best for | From | Score |
|---|---|---|---|
| Silentnight Sofia 1200 Mirapocket | Best overall | Mid range | 7.2 / 10 |
| Emma Original Lite Mattress | Best value zoned | £199 | 7.3 / 10 |
| Origin Hybrid Pro Mattress | Best all-round specification | £374 | 8.4 / 10 |
| Origin LumbarCloud Mattress | Best for heavier sleepers | £797 | 8.2 / 10 |
Silentnight Sofia 1200 Mirapocket: Best overall
Mid range · 7.2 / 10
Zoned 1,200 pocket springs, firmer under the lumbar and more giving under shoulder and hip. The 60 night comfort exchange buying direct matters more here than almost anywhere, because people buying with back or leg pain frequently get firmness wrong in one direction or the other and want to correct rather than start again.
Buy it if
You want zoned medium-firm support and the ability to change firmness if you misjudge it.
Do not buy it if
You are over about sixteen stone.

Emma Original Lite Mattress: Best value zoned
£199 · 7.3 / 10
A three-zone pocket spring layer at £199. Zoning varies spring gauge along the mattress, which is the most direct way to hold the pelvis level, and this is the cheapest zoned mattress I know of in Britain.
Buy it if
You want the right construction without spending much while you work out what helps.
Do not buy it if
You are over about fifteen stone.

Origin Hybrid Pro Mattress: Best all-round specification
£374 · 8.4 / 10
The highest scoring mattress on this site at 8.4. If your mattress is over seven years old or has a dip, replacing it with something genuinely good matters more than finding a specialised one.
Buy it if
Your current mattress is old and you want a straightforwardly good replacement.
Do not buy it if
You need very deep support for a heavier build.

Origin LumbarCloud Mattress: Best for heavier sleepers
£797 · 8.2 / 10
Thirty-five centimetres and up to 8,000 springs. A heavier sleeper sinks further at the hips, which tilts the pelvis and is exactly the mechanical situation to avoid. Depth is what stops that.
Buy it if
You are of heavier build and your hips sink on everything you have tried.
Do not buy it if
You are under about eleven stone.

Firmness, and which direction you are wrong in
Medium-firm is the usual starting point and the useful version depends on your weight and position.
| Position | Aim for |
|---|---|
| Side | 4 to 6 |
| Back | 6 to 8 |
| Front | 7 to 9 |
A stated firmness is relative. 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 supports less than the number implies.
Lower back ache on waking that eases as you move usually means too soft. Hip or shoulder pain when side sleeping usually means too firm. Those two are more reliable than any rating, because they measure the outcome.
Positional changes, which are free
These come from standard physiotherapy advice and cost nothing to try for a week.
Side sleeping: a pillow between the knees. An unsupported top leg falls forward and rotates the pelvis while the shoulders stay put, twisting the spine along its length all night. A folded duvet tests it before you buy a body pillow.
Back sleeping: a pillow or rolled towel under the knees, which lets the pelvis tilt slightly and takes tension off the lower back.
Front sleeping: generally the position least well tolerated with lower back pain. If you sleep this way, a thin pillow under the hips reduces the arch, and a very low pillow or none at all under the head.
A physiotherapist can advise on what suits your particular presentation, which a product page cannot.
Check these before spending anything
A dip in your mattress. Lay a straight edge across it and measure the deepest gap. Over about 25 millimetres and the mattress is done, and no topper will help.
Your slat spacing. Over about 7.5 centimetres apart and the base is causing sagging and voiding most guarantees. Plywood costs a few pounds.
Your pillow height. Less directly relevant to sciatica, and worth ruling out while you are checking things.
The age of the mattress. Over seven years, replace rather than modify. Under five and sound but too firm, a topper is the cheaper route.
What not to buy
Anything sold as orthopaedic on the strength of the word. It is not regulated and carries no specification.
The firmest mattress available. Over-firming is the most common overcorrection, and for a side sleeper it concentrates pressure at the hip, which is the last thing you want.
A very high spring count, expecting more support. Above about 2,000 in a king, counts rise using thinner wire.
A topper on a mattress that has dipped.
Anything described as therapeutic or medically approved. 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 front sleepers, and too firm as a general recommendation here. Over-firming is the usual mistake. |
| Mlily Premier 2000 Ortho | A sound firm mattress. Ortho in the name is positioning rather than a specification, and firm suits a narrower group than the label suggests. |
| Ergoflex 5G | Best-in-class motion isolation and a company trading since 2006. Foam conforms rather than zoning, so it does not address pelvic alignment directly. |
| Inofia Cloud-Lux | A pillow-top adds a soft quilted layer that wears faster than the core. The wrong direction if your hips already sink. |
| Nectar Premier Hybrid | The 365 night trial is genuinely useful when you are uncertain, and on construction others give you more per pound. |
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 is best for sciatica?
Medium-firm is the usual starting point, adjusted for weight and position: side sleepers 4 to 6, back sleepers 6 to 8, front sleepers 7 to 9. A mattress can stop making symptoms worse; it is not a treatment, and sciatica needs assessment by a clinician.
Should I sleep with a pillow between my knees?
If you sleep on your side, it is worth trying for a week and costs nothing with a folded duvet. An unsupported top leg falls forward and rotates the pelvis, twisting the spine along its length all night.
Can a mattress cause sciatica?
A mattress does not cause sciatica, and it can aggravate symptoms by holding the spine in a poor position for eight hours. Lower back ache on waking that eases as you move usually points to a mattress that is too soft.
When should I see a doctor about sciatica?
Urgently if you have numbness around the genitals or buttocks, difficulty passing urine, loss of bladder or bowel control, or weakness in both legs. Otherwise see a GP or physiotherapist, particularly if pain is severe, persistent or worsening.
