Choosing a baby sleeping bag might seem simple, but not all sleeping bags are made to the same standards.
With so many options available online, it can be difficult for parents to know what makes a sleeping bag safe and what features really matter. While colour, design and price often catch the eye first, safety should always be the top priority.
A well-designed baby sleeping bag can help create a comfortable sleep environment and provide reassurance that your little one is sleeping safely. However, there are several important factors every parent should check before making a purchase.
1. Has It Been Tested to Recognised Safety Standards?
One of the first things to look for is whether the sleeping bag has been tested to recognised safety standards.
Safety standards help ensure that products have been assessed for important factors such as fit, construction, durability and potential hazards.
At Slumbersac, our sleeping bags are:
✔ Tested to BS EN 16781 European and UK safety standards
This standard covers essential safety requirements for children's sleeping bags and helps give parents confidence in the product they are choosing.
If a brand does not clearly state which safety standards their products meet, it is worth asking before you buy.
2. Does It Fit Properly Around the Neck and Arms?
A sleeping bag should fit securely around your baby's neck and armholes.
If these openings are too large, there is a risk that a baby could slip down inside the sleeping bag. If they are too tight, they may be uncomfortable.
When choosing a sleeping bag:
➤ Follow the manufacturer's sizing guide
➤ Choose the correct size based on your baby's height
➤ Check that the neck opening sits comfortably without being loose
➤ Ensure the armholes fit securely
A properly fitted sleeping bag should allow freedom of movement while remaining safely in place throughout the night.
3. Is the Size Based on Height Rather Than Age?
Babies grow at different rates, which means age alone is not always the best guide when selecting a sleeping bag.
The safest fit is usually achieved by choosing a sleeping bag based on your baby's height rather than simply their age.
A sleeping bag that is too large can compromise safety, while one that is too small may be uncomfortable and restrict movement.
Always check the manufacturer's size guide before purchasing.
4. Has the TOG Rating Been Independently Tested?
TOG ratings tell you how warm a sleeping bag is, helping parents choose the right option for their room temperature.
Unfortunately, not all TOG ratings are independently verified.
Independent testing provides reassurance that the stated TOG rating accurately reflects the warmth of the sleeping bag.
At Slumbersac, all TOG ratings are independently tested by Intertek.
As a guide:
✔ 0.5 TOG: Suitable for room temperatures above 24°C
✔ 1.0 TOG: Suitable for room temperatures of 18–24°C
✔ 2.5 TOG: Suitable for room temperatures of 15–21°C
✔ 3.5 TOG: Suitable for colder rooms below 18°C
Remember that TOG ratings should always be chosen based on room temperature rather than the season.
5. Are the Fabrics Independently Certified?
Your baby's skin is delicate, which is why fabric quality matters.
Look for sleeping bags made from materials that have been independently tested for harmful substances.
Slumbersac sleeping bags are made using:
✔ OEKO-TEX Standard 100 certified fabrics
This certification means every component of the fabric has been tested against strict safety criteria, providing additional reassurance for parents.
6. Has the Sleeping Bag Been Flammability Tested?
While many parents focus on warmth and comfort, flammability testing is another important safety consideration.
Sleeping bags should be tested to ensure they meet recognised flammability requirements.
Slumbersac sleeping bags are:
✔ Flammability tested to EN 14878:2007
This testing forms part of our wider commitment to product safety and quality.
7. Are the Fastenings Secure and Well Designed?
Zips, poppers and fastenings should be durable, secure and designed with safety in mind.
A good quality sleeping bag should have:
➤ Strong zips that open and close smoothly
➤ Secure fastenings that stay in place
➤ Protective zip covers where appropriate
➤ Durable construction that withstands regular washing, tumble drying and everyday use
These details may seem small, but they contribute significantly to overall product safety and longevity.
8. Is There Enough Room for Natural Movement?
A sleeping bag should never restrict your baby's natural movement.
Babies need room to stretch, wriggle and move their legs comfortably during sleep.
Look for designs that provide generous legroom while maintaining a secure fit around the upper body.
This helps balance comfort and safety.
9. Is the Brand Transparent About Testing and Certifications?
Trustworthy brands are usually happy to explain how their products are tested and certified.
Before buying, check whether the brand clearly provides information about:
➤ Safety standards
➤ TOG testing
➤ Fabric certifications
➤ Product testing procedures
Transparency is often a good indicator that a company takes safety seriously.
10. Does the Sleeping Bag Come from a Specialist Sleep Brand?
Specialist baby sleep brands often have years of experience designing products specifically for safer sleep.
Choosing a sleeping bag from a trusted specialist brand can provide greater confidence that safety has been considered throughout the design process.
