Which cot mattress brand to buy
Our tough tests look for any hidden safety issues, and assess the firmness and body support of each cot mattress. But we also ask parents how happy they are with their cot mattress brand.
Although all cot mattresses look generally similar, there are differences in the materials used and their construction, which can mean they don’t provide the comfort, support or convenience you think you’re getting.
Best vs worst cot mattress brands compared
Our tests have uncovered two cot mattresses that pose a potential suffocation risk and, as a result, we’ve given them both a score of 0%.
As you can see, there’s a sizeable difference between the best and worst cot mattress in our tests, and varying feedback from parents who own cot mattresses from these brands.
Common cot mattress problems
- Cover shrinks in the wash and zip ripples, which affects mattress size.
- Only partially waterproof, so leaks may soak through to the core.
- Mattress is not durable, and loses firmness and height after a year or two of using it.
Our reviews will tell you how easy it is to wash the cover, and whether it shrinks at all, because a shrunken cover can compress the mattress and lead to an unsafe gap where your baby could trap a limb.
We also check to see how resistant each cot mattress is to taking moisture into its inner layers, and whether a mattress changes at all after two to three years of constant use.

How we help you to choose the best cot mattress
Our tough tests investigate the firmness of each cot mattress and how well it supports the body of a baby and a toddler, which we assess using a 12kg and a 20kg dummy. We use two heavy weights for the head and the bottom, which shows us whether a cot mattress will sag or be supportive.
Babies sleep a lot, so we check whether it’s durable and will offer a good level of body support night after night, as your child grows bigger.
