Cot-bed mattresses reviewed - read our verdicts

Section: Shopping Ideas

Which type of cot-bed mattress will suit you and your baby best? Check out our reviews of the best ones on the market to help you decide which mattress to invest in.

A cot-bed mattress is an important purchase because your child will be sleeping on it until around age four.

Cot-bed mattresses come in two standard sizes: 120cm x 60cm and 140cm x 70cm; make sure you buy the correct size for your cot-bed. There shouldn’t be more than a 3cm gap between the mattress and the sides of the cot-bed.

The mattress should give good support to your growing child. Whether you choose one with springs or one without is largely down to price and personal preference.

If allergies run in the family, invest in a hypoallergenic mattress with washable covers. 

Check the label to ensure your new cot-bed mattress conforms to British safety standard BS 1877-10:1997. For advice on how to help your baby have a safe night’s sleep, visit
