Choosing a children's mattress
Low-emission sleep surfaces for the room your child uses most.
6 min read · Updated July 2026
Quick answer
Look for a mattress with low-emission certification and, ideally, natural fillings. Air any new mattress well before use, and pair it with daily ventilation.
Key takeaways
- Certification for low emissions is the key thing to look for.
- Natural fibres reduce off-gassing; certified foam is a good-value alternative.
- Air a new mattress in a ventilated room before first use.
Why it matters for children
Children sleep for many hours a night with their faces close to the mattress, so reducing off-gassing where they sleep is worthwhile. It's one of the few nursery items genuinely worth investing in.
What to look for
Prioritise low-emission certification. Natural fibre fillings reduce off-gassing further, while certified low-VOC foam offers similar reassurance at a lower price. Breathability matters for safe sleep too.
Setting it up well
Unbox and air any new mattress in a ventilated room for a day or two, use a washable breathable protector, and keep the room aired daily.
