Frequently Asked Questions (FAQs)

1. Is memory foam mattress good for newborns?

To help prevent Sudden Infant Death Syndrome (SIDS) and suffocation, it is important to pick a foam crib mattress that is designed for infants. It should be firmer as opposed to softer. The American Academy of Pediatrics (AAP) recommends avoiding memory foam crib mattresses or mattress toppers.

2. What type of mattress is best for a cot?

Your baby's cot mattress should be firm, flat and supportive. This is because a soft surface is more likely to contour to your baby's body and could increase the risk of sudden infant death syndrome (SIDS). Don't choose a mattress that feels comfortable for you!

3. Can baby sleep on memory foam mattress?

The mattress itself should be firm with a tight fitting sheet. Typically, memory foam mattresses do not fit this criteria as your baby could sink too much and suffocate if they rolled over on their tummy.

4. How thick should a cot mattress be?

We recommend a cot mattress of 10 cm thickness which should provide adequate support to your baby's needs, and hold its shape better. Avoid 7-8 cm cot mattresses unless it's only for occasional use.
