Our tough cot mattress testing puts the products through their paces, ensuring they are supportive, durable and safe for your little one to use.
We've tested six cot mattresses - finding two to be a cut above the average, and come with Best Buy recommendations.
On the face of it, a cot mattress is a simple product, and you'd maybe believe that they are all the same. But our testing has found this to not be the case.
There is a big difference between the levels of support different cot mattresses give your child. Several fail multiple safety tests, so could become serious hazards for your baby from the off, or after several years of use.
This sprung cot mattress from Cuggl is one of the lower-priced ones we've tested. It's a simple design: the springs in the core are sandwiched between two layers of foam, with a fixed inner cover and removable outer cover on top.
The removable cover is only machine washable up to 40u00baC; we would recommend a cover that can be washed at up to 60u00baC as this will ensure any nasty germs are killed.
We've also tested the Cuggl to see how well it supports both a baby and toddler, if it will be good to use after several years of use, and if it will keep your child safe.
The 'dual' in this cot mattress refers to it being dual-sided: one side for newborns under 18 months and one for 18 months and over.
The difference? The newborn side has a coconut fibre mat underneath the outer foam to increase its firmness.
This extra functionality comes with a price tag with this being one of the more expensive cot mattresses we've tested.
But is it worth the pennies? Our testing has found no correlation between the price of cot mattresses and how they perform in our tests, so read our full to find out if this is one of our latest Best Buys.
Being under £70, this cot mattress is cheaper than the majority we've tested.
Unlike the Cuggl and Ickle Bubba cot mattresses already mentioned, this one has a fibrous-web foam core. In principle, this allows for greater air flow through the mattress to help regulate your baby's temperature.
Its removable outer cover is also washable at 60u00baC.
There are plenty of websites and forums offering reviews of cot mattresses. So why are Which? reviews a cut above the rest?
If a cot mattress we test doesn't pass the requirements set out by the safety standard we test to, we don't recommend it. So you can be certain that a recommendation from Which? means the cot mattress is safe and supportive, not just when it's new, but for years to come.
