Creating the perfect sleep environment for your baby is essential for both safety and comfort so we put the best cot mattresses to the test to help you choose the right one for your child.

It's important to buy a brand new cot mattress for a newborn baby. This is because there is evidence that second-hand mattresses can increase the risk of Sudden Infant Death Syndrome (SIDS) (opens in new tab). ‘It is essential that the mattress you choose for your baby is flat, firm, and offers your baby lots of support as she sleeps,’ says Vickie Bowles of The Baby Academy. ‘Therefore, ordering the correct size mattress for your cot is important. Make sure that there are no gaps and that it fits your baby’s cot perfectly,’

For optimum baby sleep safety, make sure your baby's cot mattress doesn't sag in the middle - or anywhere else. In addition, it should feature the British Standards’ prefix BSI number BSEN716. This requires a mattress to meet certain standards on things like firmness, mattress shrinkage after washing, and choking hazards like zips.

How we tested the best cot mattresses

To help you make this very important decision, we asked parents with babies aged between nine months and almost two years old to put a range of the top baby cot mattresses to the test. Overall, they tested the mattresses for a number of weeks, and we used their in-depth feedback and insights to compile this buying guide to help you choose the best cot mattress for your baby.

Our testers found the SnuzSurface Duo Dual-Sided Cot Mattress (opens in new tab) to be the best cot mattress. It scored well for value, design, innovation, quality, and comfort.

Before you can use the SnuzSurface cot mattress (opens in new tab), you need to let it ‘settle’ and ‘breathe’ for seven days. This is because it needs to reform its proper shape after being vacuum packed for transport. This can be a little frustrating. However, it is at least nice to look at while you wait - the stylish mattress comes in a deep purple and brilliant white design.

When you can eventually use it, you’ll see it doesn’t just boast good looks. It’s been created with two differing supports: one for a newborn and the other for a toddler. To change these, simply unzip the mattress from its mesh cover and swap it around.

Our tester Charlotte tried out both supports on her baby. Overall, she was surprised by the difference they made in her daughter's sleep. ‘She kept waking up on the firmer, newborn side, but she much preferred the softer support that allowed her a bit more movement in her sleep.’

But the innovation doesn’t stop there; the mattress is covered with a removable 3D mesh. This is is fully washable, so you can confidently get rid of those nasty dust mites. But more importantly, it's fully breathable, allowing for good air circulation at night.

‘Even with a heavy cold and sleeping face down, I felt confident that this mattress provided Adelaide with great breathability,’ said Charlotte. While definitely not a budget buy, this cot mattress comes in at £139 and is good value for money, considering it has some really nice, innovative features. For this reason, we’ve named it our best buy cot mattress in this buying guide.

Tried and tested by: Mum Amelia and her daughter Olga 

The NaturalMat Quilted Spring Mat (opens in new tab) is unrivalled when it comes to environmental credentials. It’s hand-made in Devon from organic lambswool and natural latex, coconut fibre (coir) and cotton. ‘As a parent, this is genuinely something I lose sleep over,’ said our tester Amelia. ‘I want to buy products that I know will help towards preserving the planet for my child’s future. I love knowing where the product was made, what it was made from and that it (and its packaging) won’t end up in landfill in the future.’

Unlike most cot mattresses that are (at least at the beginning) brilliant white, the NaturalMat has a more natural colourway. While this could be off-putting to those who find chemical protection and white bedding more appealing, the quality of this product is ‘second-to-none’, according to Amelia. Her daughter Olga agreed - she consistently got a better night’s sleep on this mattress than any of the others mattresses she slept on.

It’s chemical-free, non-toxic and naturally fire retardant. The cotton mattress cover boasts an OEKO-TEX®-certified hypoallergenic treatment to protect against bed bugs, dust mites, mosquitoes and moths. It also has a five-year manufacturer’s guarantee.

At £325, this is the most expensive cot mattress on our list. However, Amelia thinks if you are invested in the environment and have a big enough budget, it’s definitely worth it because of NaturalMat's high-quality materials and hypoallergenic credentials, not to mention that her daughter slept better on it.

It’s a common misconception that an IKEA mattress needs an IKEA cot. But this isn’t the case and this 140 x 70 cm mattress fits our tester’s cot perfectly. ‘It's actually a nice fit, and there are no gaps where I felt concerned Margot might put her hands down the side,’ said mum Hollie.

IKEA’s Jättetrött Pocket Sprung Cot Mattress (opens in new tab) is lightweight, and Hollie was even able to take it away in her car when she headed off on a staycation with Margot. She also liked its firmness and how the pocket springs give it a flexible feel, but the major plus is its removable cover. This makes it very easy to clean in the machine should your baby have an accident in the night.

‘It's easy to get the outer cover back on the mattress once you've removed it so it's not a laborious task every time you want to wash it,’ said Hollie, who also liked the attention-to-detail with the zips - which are carefully hidden under a pouch - away from little fingers.

At under £100, this mattress offers real value for money, combining quality and a low price. ‘It's affordable, and it's good quality with pocket springs that I found nice and supportive for Margot,’ said Hollie. For these reasons, we’ve named IKEA’s Jättetrött Pocket Sprung Cot Mattress our best budget buy cot mattress.

Purflo’s one-of-a-kind design is not your average cot mattress. Its hollow frame design means that it’s fully washable and breathable, as well as being lightweight. This cot mattress does require a bit of assembly. ‘[I] wasn’t thrilled (in fact, dismayed) when the Purflo cot bed mattress (opens in new tab) came in 20 separate pieces,’ admitted our tester Darryl Baker. ‘If you don't want to or can't put furniture together, this isn't for you as it requires an initial assembly of the frame.’  But it comes with instructions, and she got there in the end.

Once you’ve put in the effort, you will be richly rewarded. The innovative mesh fabric supports your baby while allowing them to breath easily. Darryl said that her daughter Cole had a cold, but the lightweight mattress helped her congestion at night and during naps, giving her ‘a comfortable night’s sleep.’ One of the most exciting features for parents is that, unlike any others, this cot mattress is fully washable. You can be confident that all those nasty cold and cough bugs, plus any dust mites, will be washed away in the machine.

At £189, this cot mattress is a pricey purchase, but Darryl believes that it’s worth spending the extra if you are 'someone who is open to trying something at the forefront of new designs and looking for the safest sleeping space for their baby'.

Tried and tested by: Mum Hollie and her nine-month-old

The Silver Cross Truefit Cot Mattress (opens in new tab) has oodles of innovative features that you don’t often find and probably haven’t even considered when choosing a cot mattress. ‘I didn't realise cot bed mattresses could have so many different features like the True Fit technology and the dual sides, but now that I have used a mattress with these I wouldn't look back,’ said our tester Hollie.

The standout feature is that it’s dual-sided, with a firmer side for newborns and a softer one for toddler. ‘It's really good quality - it's very soft and springy and feels like it will be very comfortable for your baby,’ said Hollie, who used the newborn side for her nine-month-old.

The double-sided feature extends the lifetime of this mattress and means that it can be used till your little one gets their ‘big’ bed. It will stay clean all that time too because it has a washable cover that can be thrown in the machine when it gets dirty, plus it’s hypoallergenic - a real plus if you have a history of mild allergies like Hollie. While the price point is on the higher side, our tester thoroughly recommends it: 'I can't see why any parent wouldn't be happy with this mattress as it's a well-thought-out product, uses high-quality fabrics and has useful features'.

Tried and tested by: Mum Rebecca and her 16-month old son Louis

This Little Green Sheep Twist Natural Cot Mattress (opens in new tab) comes with dual sides: a firmer one for newborns and a softer one, specially designed for older babies who move around more in the night. ‘Suitability for a toddler isn’t something I've seen with many cot mattresses, so this stands out to me,’ said our tester Rebecca.

As it’s made of all-natural materials, including coconut, latex, wool and cotton, this mattress is also temperature regulating, and Rebecca reported that her 16-month son Louis slept very well and was ‘neither too hot nor too cold’. Its natural credentials make this a good option for babies with allergies or a history of family allergies and its breathability is second to none – even Rebecca could breathe when she tested it out for herself. Like all coir mattresses, this Little Green Sheep one is environmentally friendly and is recyclable once your little one has grown out of it.

As you’d expect from something that’s premium quality and has environmentally friendly ingredients, this mattress comes with a premium price point and retails at £219. ‘I think it's worthy of the ''luxury'' marketing spiel,’ Rebecca said. She’d recommend it to environmentally conscious parents but flagged that they’d also have to purchase a mattress protector separately, adding to the cost.

Tried and tested by: Mum Charlotte and her daughter 

Many parents aren’t looking for a cot mattress that does everything but just want a safe sleeping environment for their little one. Mamas and Papas Essential Pocket Sprung Mattress (opens in new tab) is for them. ‘This is a basic mattress but there’s nothing wrong with that,’ said tester Charlotte. ‘My daughter slept very well on it and it felt lovely and soft to touch.’ In addition, this mattress is on the firmer side and has an inner construction that includes ‘crush-resistant walls’.

This might not suit all babies but it’s advised that newborns especially sleep on a supportive mattress. ‘I think after the first 18 months you might have to move to another mattress that is a little softer and can accommodate more mobile toddlers,’ added Charlotte.

For parents who are worried about allergies, there is a hypoallergenic cover which is also washable to rid your baby’s cot of any dust mites and cold germs. ‘I liked that the inner part of the mattress had a wipe-clean cover as I felt confident that what Adelaide was sleeping on was really clean,’ our tester said.

This Mamas and Papas cot mattress offers good value for money and would suit a family who value functionality over style and fancy extras.
