Types of baby cot bed mattress

There are three main types of cot bed mattress, all of which offer different benefits:

1. Foam
2. Standard sprung
3. Pocket sprung

1. Foam cot bed mattresses

A foam cot bed mattress offers good support and is great value for money. They are usually made up of fillings such as reflex foam to provide a firm sleep surface for your little one.

2. Standard sprung cot bed mattresses

A popular choice, standard sprung cot bed mattresses feature open coil springs surrounded by foam and fillings. Also known as open coil mattresses, heavier versions are likely to include thicker springs and therefore will provide better support than a foam mattress.

3. Pocket sprung cot bed mattresses

A pocket sprung cot bed mattress features springs that are individually wrapped within a cloth sleeve. A pocket sprung mattress provides enhanced support and comfort, since the pocket springs adapt to your baby's movements throughout the night.

How firm should a crib mattress be?

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! Instead, if a cot mattress responds to pressure by quickly snapping back to its original shape, then it should be firm enough for your little one.
