Lumbar support cushion: what the HSE says, what the research misses, and where to place it

Do you need a lumbar support cushion?

Maybe, but not first. Searches say “lumbar support pillow”, though the British sources we read talk of a seat back or a cushion, so this page uses cushion. The usual order is to set up the chair, then to add a cushion only if the chair still leaves the small of your back unsupported.

Arthritis UK says a correctly adjusted chair will give you good support for your lower back. It adds that using back supports can help your posture when sitting at home, at work or in the car, and that upright, hard-backed chairs are better for your posture than low, soft, upholstered chairs or sofas.⁴

That is what Arthritis UK says. It is advice about comfort and posture. It is not a claim that a cushion will remove or prevent back pain, and, as the research section below shows, the evidence on that point is thin.

What the HSE says: a backrest first, a cushion if needed

The Health and Safety Executive (HSE) describes the back of the seat as the thing that should provide good lower back support, and says you can use a cushion to give additional back support. A cushion can also raise your seated position when the seat height is not right.¹ So the HSE treats a cushion as an alternative when the chair does not do the job, not as a requirement.

The HSE workstation checklist asks whether the small of the back is supported by the back of the chair.² That is the test to apply to your own chair.

At work, Arthritis UK says your lower back should be well supported and your feet on the floor, with a footrest if they do not reach.⁵ See correct sitting posture for the full HSE set-up and ergonomic desk set-up for your employer’s duties.

What the research says about lumbar supports, and where it stops

Here is what we have to say plainly. The two Cochrane-group reviews we read are about lumbar supports in general. Their abstracts do not mention chair cushions, so they cannot tell you whether a cushion on your chair helps. They are also old: 2001 and 2008. Treat what follows as the closest evidence we found, not as evidence about cushions.

A little arithmetic helps keep the numbers in proportion. The 2008 review covered 14,437 + 1,361 = 15,798 participants across the two kinds of study. But only 5 of its 15 studies met the quality bar, which is 5 / 15 = 33.3%. In the 2001 review, 4 of 13 were of high quality, which is 30.8%.

NICE guideline NG59 advises against offering belts or corsets for managing low back pain.⁸ That recommendation is about belts and corsets, not chair cushions, and we do not read it as a ruling on cushions. NICE also encourages continuing normal activities, as does the NHS, which says to stay active and not to stay in bed for long periods.⁸⁹

Finally, a caution about posture claims. A 2019 viewpoint by Slater and colleagues says that, despite an absence of strong evidence on the link between posture and pain, a large posture industry has flourished, with products claiming to “correct” posture and prevent pain.¹⁰ That applies to any cushion advertised with such a claim.

What can be said fairly is that a cushion may make a seat more comfortable and may add support where the backrest does not, as the HSE and Arthritis UK describe. What cannot be said is that it relieves or prevents back pain. No study we read tested that.

How to place a lumbar cushion on a chair, in a car or on a sofa

No British source we read describes where a cushion should go, so this part is a drafting protocol from Chutex, not sourced advice. It uses only the HSE’s own test, whether the small of the back is supported by the chair back.²

Re-checking the knee gap matters because a thick cushion pushes you forward. The HSE gap is 2 to 3 cm, which is 0.79 to 1.18 in, between the seat edge and the back of the knee.¹

In the car

The HSE lists driving for long periods, especially if the seat is not or cannot be properly adjusted, among the causes of back pain at work.³ That is about adjusting the seat. We found no UK road-safety guidance on lumbar cushions in cars, so this page gives none beyond that.

On a sofa

Arthritis UK says sofas are worse for posture than upright, hard-backed chairs.⁴ If you use a cushion on a sofa, the same test applies: is the small of the back supported, and can your feet reach the floor?

Connected versus ordinary cushions: what a sensor adds

Some lumbar cushions have no electronics. Dorsi, from Chutex, is a connected lumbar cushion with a 9-axis sensor. It records tilt angles while you do guided movements on it, and the Chutex app uses them to build an indicative lumbar mobility assessment.¹²

We found no institutional source that evaluates what a sensor in a cushion adds. So the plain statement is this: a sensor can record how you move on the cushion. The Chutex app guides movements and mini-games that support regular low-back activity. It cannot tell you why your back hurts. Dorsi is a wellness product. It does not promise pain relief and does not replace your GP.¹²

Buying one: price, returns and care

This page gives no prices, sizes or maker’s return terms for lumbar cushions, because we read none from a maker’s page on the day of writing. For the Dorsi price, see the product block on this page.

One general rule is worth knowing. GOV.UK guidance for sellers says that if you buy online, by post or by phone, you can cancel within 14 days of receiving the item even if it is not faulty. After telling the seller, you have a further 14 days to return it, and the seller must refund within 14 days of getting it back.¹¹ If an item is faulty or not as described, you are entitled to a full refund, and a repair or replacement may be demanded if it is returned within 6 months.¹¹

That is the general legal position on GOV.UK. It is not any particular shop’s policy, so check the seller’s own terms before you buy.

When back pain needs a GP

A cushion is a comfort aid, and it should not delay a call about pain. The NHS says to stay active and not to stay in bed for long periods, and to see a GP if the pain has not improved after a few weeks of treating it at home.⁹ For back pain with a loss of feeling around the genitals or anus, or changes in your bladder or bowels, the NHS says to call 999 or go to A&E.⁹
