Best leg pillows

Raising your legs and separating your knees are two different jobs, and the pillows that do them look similar.

I earn a commission if you buy through some links on this page. It never changes what I recommend, and I publish negative verdicts on brands I earn from. Editorial independence.

Some leg symptoms need assessment

People buy leg pillows for swelling, aching and circulation. Swelling in one leg, sudden swelling, pain with redness or heat, or leg pain with breathlessness needs urgent medical attention. Persistent swelling in both legs should be discussed with a GP.

A pillow is a comfort aid. If a clinician has recommended elevation, take the height and duration from them rather than from a product page.

Two different products get called leg pillows.

An elevation wedge raises both legs above hip level, lying on your back. The job is drainage and comfort.

A knee pillow sits between the knees, lying on your side. The job is stopping your pelvis rotating. See knee pillows for that one.

The picks

The pick, if you want one answer

Simba Body Pillow, 7.4 / 10. A long bolster, which does the side-sleeping job properly and adapts to elevation when you need it.

Simba Body Pillow: Best all-round option

Mid range · 7.4 / 10

Scores 7.4. A firm full-length bolster holds its shape under legs, which is where soft fibre-filled products fail: they compress within weeks and stop doing the job.

Buy it if

You want one pillow that works between the knees and under the legs.

Do not buy it if

You need a fixed incline held all night.

Kally Sleep Body: Best value

Budget to mid · 7.3 / 10

Scores 7.3. A reasonable entry into the format. Most people who try elevation discover within a week whether it makes a difference, which makes an inexpensive first purchase sensible.

Buy it if

You want to spend less while finding out whether elevation helps.

Do not buy it if

You need maximum firmness under the legs.

Simba CustomFlex Pillow: Best head pillow to use alongside

Mid range · 7.7 / 10

Removable fill. Lying with the legs raised changes how your upper body settles, so re-run the ten minute check afterwards: lie in position and have someone look from the side, and your head should sit in line with your torso rather than propped.

Buy it if

Your legs are raised and your neck now aches.

Do not buy it if

Your head pillow height is already right.

Silentnight Airmax Topper: Best if the mattress is the problem

Budget to mid · 7.4 / 10

Scores 7.4. Worth ruling out: hip and thigh discomfort when side sleeping is usually a mattress too firm to let the hip sink in, which elevation does not address at all.

Buy it if

Your legs ache because the mattress is too firm at the hip.

Do not buy it if

Elevation is what you actually need.

How high, and for how long

The usual guidance where elevation is recommended is legs above heart level, which in practice means roughly 15 to 30 centimetres at the ankles when lying flat, with the knees slightly bent rather than locked straight.

Two things matter more than the number.

Support the whole lower leg, not just the calf. A short wedge under the calves alone leaves the heels hanging, which concentrates pressure exactly where it is least welcome.

Do not create a sharp bend behind the knee. A steep wedge with the crease directly behind the knee is uncomfortable and counterproductive. A long gentle slope is better than a short steep one.

If elevation has been recommended clinically, follow the height and duration you were given.

Which product does which job

Three similar-looking products
ProductPositionJob
Elevation wedgeOn your backRaises both legs above hip level
Knee pillow or bolsterOn your sideStops the top leg falling forward and rotating the pelvis
Under-knee cushionOn your backLets the pelvis tilt, easing the lower back. Not elevation.

The third row is worth separating out. A small pillow under the knees for lower back relief is not the same as elevating the legs, and it is free to try with a folded towel.

If you sleep on your side, elevation does not survive the night

This is the practical limit nobody mentions.

An elevation wedge only works while you are on your back. Turn onto your side and your legs come off it, which for most people happens within an hour or two.

So elevation suits people who genuinely sleep on their back all night, or people using it for a period before sleep rather than through it. Half an hour with the legs raised before bed is a realistic routine; eight hours is not, for most side sleepers.

If you sleep on your side, a firm bolster between the knees is the product that actually stays in play.

What the fill has to do

Firm enough to hold under legs. Legs are heavy, and soft fibre fill compresses within weeks. This is the commonest reason a leg pillow ends up unused.

A removable washable cover. The pillow itself usually cannot be machine washed.

Not too warm. Dense foam under the legs adds heat in a spot with no air movement, which matters if the legs are the part that already feels uncomfortable.

And check the width. A narrow wedge lets the legs roll off either side, which is a common complaint and easily avoided by measuring before buying.

What not to do

Use a pillow instead of seeing a GP about swelling in one leg, sudden swelling, or leg pain with redness, heat or breathlessness.

Create a sharp bend behind the knee. A long gentle slope beats a short steep one.

Support the calves only. The heels end up hanging.

Buy soft fibre fill. Legs are heavy and it compresses within weeks.

Expect elevation to survive the night if you sleep on your side.

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.

Considered and not recommended here
ProductWhy it is not on the list
Aeyla Dual PillowA head pillow with two firmness options, useful because raising the legs changes how the upper body settles and the head height may need adjusting.
Simba Hybrid PillowThe highest scoring pillow on this site at 7.9, and a head pillow rather than a leg one. Named because people frequently solve the legs and leave the neck wrong.
Simba TopperThe highest scoring topper here at 7.5. If hip or thigh discomfort is the real complaint, a too-firm mattress is the more likely cause than leg position.
Soft fibre-filled leg wedgesPleasant in the shop and the most common failure. Legs are heavy, the fill compresses within weeks, and the wedge stops holding any useful height.

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

How high should I elevate my legs?

Where elevation is recommended, the usual guidance is legs above heart level, roughly 15 to 30 centimetres at the ankles, with the knees slightly bent rather than locked. If a clinician recommended it, take the height and duration from them.

What is the difference between a leg pillow and a knee pillow?

An elevation wedge raises both legs above hip level while you lie on your back. A knee pillow sits between the knees while you lie on your side, to stop the top leg falling forward and rotating your pelvis.

Does leg elevation work if I sleep on my side?

Not through the night. An elevation wedge only works while you are on your back, and your legs come off it when you turn. Half an hour with the legs raised before bed is realistic; eight hours is not.

When should I see a doctor about leg swelling?

Urgently for swelling in one leg, sudden swelling, or pain with redness, heat or breathlessness. Persistent swelling in both legs should be discussed with a GP rather than managed with a pillow.
