Is Memory Foam Safe for Baby Mattresses?
Published 12 Jan 2026
Thank you - yes, this is important to raise, but it's easy to answer:
This is a big NO to using memory foam in a baby mattress. Here's why:
Suffocation Risk
We know babies should sleep on their backs, but if they turn and go face down on memory foam, it could sink and hinder their breathing.
Remember the basic rule of a baby mattress: a firm, flat surface. Memory foam doesn't offer this.
Carbon Dioxide Pooling
This can occur with memory foam. Your baby's head could make a depression, and because your baby breathes out carbon dioxide (which is heavier than air), it can accumulate in the dip. Your baby then breathes in stale, used air that's low in oxygen. This is also made worse by poor ventilation.
Chemical Concerns
There are many more chemicals involved in the manufacture of memory foam. You don't want these VOCs (volatile organic compounds) anywhere near your baby.
Overheating
Memory foam is warm - yes, OK for senior citizens, but not for babies. Overheating adds to the risk factor of cot deaths.
Well, let's stop there! That should be enough to put you off memory foam for your baby.
