The right cot mattress not only helps your little one get a sounder sleep, but it supports her as she grows. With plenty of different cot mattresses to choose from, the choice can seem overwhelming, so we've put together our top market picks and Mother & Baby award winners here, so you really can get the best cot mattresses for your baby.
What are the different kinds of cot mattresses on the market?
When it comes to choosing a mattress for your baby's cot, you have three main choices: foam, spring or natural fibre.
- Foam cot mattresses are usually the cheapest and lightest option. Foam cot mattresses come in a variety of thicknesses, but it's recommended you go for a firmer design to avoid the risk of suffocation and Sudden Infant Death Syndrome (SIDS).
- Spring mattresses (made with sturdy coils) and pocket sprung (made with steel springs that adjust to your baby's body) are other popular options.
- Natural fibre cot mattresses are recommended for moisture absorption, or PurFlo cot mattresses are popular for air circulation.
How do you choose the best mattress for you and your baby?
It all depends on your price, how sensitive your baby is and personal preference for firmness.
What size do cot mattresses come in?
Some general advice for all cot mattresses: They come in two standard sizes: 120cm x 60cm and 140cm x 70cm. Make sure there isn't more than a 3cm gap between the mattress and sides of the cot-bed!
