Baby sleeping bags: UK regulator warns about bags with no arm holes or with a hood
On 1 October 2026 the UK's OPSS issued safety alert PSA9: baby sleeping bags used for unsupervised sleep are dangerous if they have no arm holes or include a hood. The risks are suffocation and overheating. Nearly 50 recalls have been published since 2023. What to check at home and how to get your money back.
On 1 October 2026 the UK Office for Product Safety and Standards (OPSS) issued Product Safety Alert PSA9 on baby sleeping bags. It is not about every sleeping bag, but about two specific designs: those without arm holes, and those with a hood. OPSS asks parents and carers not to buy such products and to stop using them.
Which products the alert covers
It covers products marketed or intended as bags for babies to sleep in unsupervised, in a cot or crib. It does not cover items designed to be worn in a pram, such as a pramsuit or a muff, and it does not cover swaddles. It also does not apply to sleeping bags that meet the voluntary standard BS EN 16781:2018, which sets safety requirements for children's sleep bags for use in a cot.
A baby sleeping bag as such is a normal and even recommended item: NHS safer-sleep guidance lists a baby sleeping bag as one of the options, and says that if you do share a bed with your baby, a sleeping bag is safer than swaddling. The problem is the design.
Why a bag without arm holes is dangerous
OPSS names two harms — suffocation and overheating.
Suffocation. Arm holes keep the baby in position. Without them, a baby can slip down into the bag and the fabric can cover the nose and mouth, which can lead to asphyxia. A hood does the same: the material moves on its own and can end up over the baby's face.
Overheating. Heat-retentive materials, or anything that encloses a baby's head, stop heat escaping. A baby left for too long gets too hot — and overheating raises the risk of sudden infant death syndrome (SIDS).
The alert did not come out of nowhere: OPSS has published nearly 50 recalls or product safety reports for dangerous baby sleeping bags in the UK since 2023.

Take the bag out and look at two things: does it have arm holes, and does it have a hood. If there are no arm holes, or there is a hood, do not use it for unsupervised sleep.
If the product was marketed for unsupervised baby sleep, OPSS advises contacting the business that supplied it: you may be entitled to redress under the Digital Markets, Competition and Consumers Act 2024. That includes the online marketplaces through which most of these bags arrive.
Unsafe products still on sale can be reported to local Trading Standards. In England and Wales that is done through the Citizens Advice consumer helpline on 0808 223 1133.
What safer sleep looks like under NHS guidance
The baby sleeps on their back, in the feet-to-foot position, on a firm, flat mattress. The cot should be clear of anything that could cover the face: no pillows, duvets, cot bumpers, loose blankets, soft toys, pods or nests.
Keep the room between 16C and 20C. Check whether the baby is too hot by feeling the chest or the back of the neck, not the hands and feet — cool hands and feet are normal. Remove hats and extra layers as soon as you come indoors or get into a car, bus or train, even if it means waking the baby.
For at least the first six months the baby sleeps in a separate cot or Moses basket, in the same room as an adult.
Also that day: a warning about baby product ads
On the same day the Advertising Standards Authority (ASA) issued a separate warning to parents and carers. After a large-scale monitoring exercise the regulator found online ads for baby products claiming to help with colic, reflux, sleep and soothing — among them ads promoting potentially dangerous products and practices that could put babies at risk of serious harm or death.
The practical conclusion is the same as with the bags: a claim in an advert is not evidence of safety. The product standard and NHS guidance are the reference points, not the ad copy.
If you are refused a refund
Start with a written complaint to the seller, then escalate. We have covered how that chain works in the UK separately: returning faulty goods and complaints and the ombudsman. If you paid by credit card and the item cost more than GBP 100, section 75 of the Consumer Credit Act also applies and the claim can be made against the card provider.
