Here's our selection of 10 of the best baby mattresses for 2025

1. Snüz Surface Pro Adaptable Cotbed Mattress, £189.95

– Best baby mattress for adaptability

Suitable from: birth | Type: Cotbed mattress | Interior: Springs and foam | Size: L70cm x W140cm x H11cm

Pros:

• Adjustable
• Grows with child
• Waterproof
• Machine washable cover
• 5-year guarantee

Cons:

• Can be a bit confusing to change firmness

A hybrid mattress combining pocket springs with foam, what sets this apart from the rest is its changeable inner layers that can be moved to adjust the firmness as your child grows. The first stage is the firmest, ideal from birth to 12 months. This is how the mattress comes set up, firm and flat. The next stage is designed for toddlers (12 months to 3 years) – just unzip and rearrange the foam layers to create a medium firmness mattress. The final stage is durable for children up to 7 years and you can switch around the foam layers however you like to suit your child's weight, age and of course, preference.

Another fantastic thing about the mattress, which is vital with a baby, is its waterproof surface and removable washable covers to help clear up the inevitable accidents.

The breathable 3D mesh cover to keep your baby cool and comfortable all throughout the night. Snüz also offers a 5-year guarantee.

Overall you can definitely tell that this is a good quality, well made mattress with both the child's comfort and the parents requirements thought about in all aspects. The instructions are very simple pictures to show you how to convert the mattress between the 3 different stages, however I did find the practice slightly less so.

2. Obaby Moisture Management Mattress, £140-£160

– Best baby mattress for moisture management

Suitable from: Birth | Type: Cot/cotbed mattress | Interior: 100% polyester base, coir, foam and polyester internal layers | Size: L120 x W60cm x H10cm - L140 x W70cm x H10cm

Pros:

• Easy to change from baby to toddler mode
• Washable covers
• Long-lasting

Cons:

• Only 2 standard sizes available
• Pricey

This truly is a mattress that will grow with your baby. There's a coir side that's suitable from birth and Obaby say will aid in muscle development and bone growth; then there's a pocket sprung side for toddlers that will give support for your toddler's back, neck and head during sleep. Our testers loved this feature and said it was clear and easy to change the side of the mattress, depending on the age of the child using it.

For the 'moisture management' part of the mattress — there's a Tencel top panel which increases moisture and humidity management. Plus, the zipped top panel can be removed and washed easily — you don't even need to remove the mattress from the cot.

There are a total of 4 sleeping positions with this mattress due to the reversible core and cover — so you can choose the right one for your baby or toddler, depending on their needs.

I cannot fault this mattress – washable covers and different sides to ensure a comfortable night sleep for your child. It's very easy to change the mattress from newborn to toddler mode and it is clear which side is for which. I love that the covers can be easily removed for washing, a must with babies and toddlers!

The mattress is made from coir, cotton, natural latex and organic lambswool. It has a firm side for babies under one year and a softer side for toddlers and the hand nested pocket springs will support your baby’s growing body as thy sleep. The comfortable quilted cover has an OEKO-TEX® certified hypoallergenic treatment that protects it from moths, bed bugs, dust mites and mosquitos and it is removable and washable at 600C. The mattress comes with a five-year guarantee.

I love the natural fillings, the dual purpose (firmer vs softer), removable covers and 5-year guarantee. This product is by far the best children’s mattress I’ve come across. Our toddler loves it, and it provides the perfect amount of support

4. CuddleCo Lullaby Hypo-Allergenic Bamboo Foam Mattress, £44.99-£59

— Best baby mattress for future-proofing

Suitable from: Birth | Type: Cot/cotbed mattress | Interior: Foam | Size: L120cm x W60cm x H11cm (cot) or L140cm x W70cm x H11cm (cot bed)

Pros:

• Great value
• Dual-sided
• Breathable and hypoallergenic fabrics

Cons:

• Only a 1 year warranty

Another baby mattress designed with 2 unique sides is this lovely option from Cuddle Co. What really makes it stand out is its specialised potty training feature — one side of the mattress has an easy-clean waterproof layer which makes it perfect for those toilet-training days. The other side that's more suited for newborns has bamboo fabric that has natural hypoallergenic and anti-microbial properties to maintain a clean sleeping surface.

The mattress is made from breathable and hypoallergenic fabrics which promotes optimal air circulation as well as a high-density Nursery Grade foam core, providing a comfy and firm sleeping surface for your baby. There's also a removable, washable cover.

Really great mattress, very high quality and a great price point. I was very surprised at the price considering how luxurious it is. I love the bamboo cover and feel that will help with temperature regulation of my baby. The flip function with the toilet training side is so well thought out! My son has generally settled reasonable well on this mattress. We think it must be very comfortable as he enjoys sleeping on it.

5. ClevaMama ClevaFoam Pocket Sprung Mattress, £156.75-£174.29

– Best for babies with flat head syndrome

Suitable from: Birth | Type: Cot or cotbed mattress | Interior: Clevafoam | Size: L120cm x W60cm x H11cm (cot) or L140cm x W70cm x H11cm (cot bed)

Pros:

• Vacuum-packed for convenience and hygiene
• Aims to prevent flat head syndrome

Cons:

• May take a while to regain proper shape when unpacked
• Pricey

With safe sleep advice to always lay your baby on their back to sleep, there have been more concerns from parents about Flat Head Syndrome or plagiocephaly. The ClevaMama ClevaFoam pocket sprung mattress aims to protect the natural round shape of your little one’s head, helping the correct development of babies’ skulls.

This hybrid mattress combines up to 362 adaptive pocket springs with Clevafoam, which was developed with researchers at Trinity College at the University of Dublin and claims to reduce pressure on the back of an infant’s head by 50 per cent. It’s not memory foam (which is not recommended for babies) although it has some similar features.

The key difference is that it’s developed to have an open cell structure, making it lighter and cooler than traditional foam mattresses and 100% breathable, according to ClevaMama, to reduce the risk of your baby overheating. Memory foam is usually a closed cell structure which makes it heavy, dense and with reduced airflow causing it to retain heat.

Parent tester Gina, mum of 3, commented: “I like that it supports their whole body and will regulate their temperature to prevent overheating. I also feel that the price is fair considering the comfort and the 3 year guarantee it comes with.”

The mattress comes with a three-year guarantee and is vacuum-packed at the point of manufacturing, so it is hygienic and compact to store if you buy it before you need to use it. However, remember it will take a little time for it to expand to its proper shape when you get it out of its packaging.

This mattress has definitely improved the quality of my baby’s sleep, she now sleeps through without crying out. Baby mattresses are often very hard and uncomfortable, but I would happily sleep on this if it were big enough!

6. John Lewis Premium Fibre Cot & Cotbed Mattress – £55/£65

– Best baby mattress for good quality at a good price

Suitable from: Birth | Type: Cot and cotbed mattress | Interior: Springs | Size: L120cm x W60cm x H10cm (cot) or L140cm x W70cm x H10cm (cotbed)

Pros:

• Well padded
• Great value

Cons:

• Only two sizes available
• Only a 1 year guarantee

If spring mattresses are too pricey, this premium fibre option from John Lewis could be a great alternative. The quilted micro-fibre mattress cover is removable for washing and helps control the temperature and comfort of your baby. Inside is a wipe-clean inner cover that helps keep the mattress clean and hygienic.

The cover can be removed and washed at 40°C so you don’t have to worry about the mattress becoming dirty and soiled.

And with a one-year guarantee, this John Lewis own-brand mattress should stay in good shape until your child is ready to move into a full-size bed.

There were no signs of sinking or wear when it came time to get rid of it. We were really pleased with how comfortable it felt, especially as it was a reasonable price.

7. Silentnight Safe Nights Airflow Cot Mattress, £129-£149

– Best baby mattress for reliability

Suitable from: Birth | Type: Cot mattress (cotbed size also available) | Interior: Polyester | Size: L120cm x W60cm x H10cm (cot) — L140cm x W70cm x H10cm (cotbed)

Pros:

• Well-priced
• Easy to clean with washable core
• Good eco credentials

Cons:

• Only 2 standard sizes available

The Safe Nights Lullaby mattress offers great value from money, especially as Silentnight is a trusted household name. The core is foam free, which means it will remain firm and cool – important considerations when it comes to creating a safe sleeping environment for your baby.

One great feature with this mattress is that it is easy to clean after an accident. As well as having a removable cover that can go in your washing machine, the core can be rinsed in the shower. It also has a hypoallergenic core and a very soft touch fabric.

Although it isn’t made from completely natural materials like some on our list, it is free from chemical treatments and is fully recyclable. Silentnight also offer a 5 year guarantee, for extra peace of mind.

8. The Little Green Sheep Twist Natural Mattress, £199-£219

– Best baby mattress for lasting power

Suitable from: Birth | Type: Cot/cotbed mattress | Interior: Organic coconut coir, latex, cotton and wool | Size: L140cm x 70cm x H10cm (cotbed), L120cm x W60cm x H10cm (cot), L122cm x W68cm x H10cm (Stokke Sleepi), L132cm x W77cm x H10cm , L132cm x W70cm x H10cm, L139cm x W69cm x H10cm (Mamas and Papas)

Pros:

• Double sided with two firmness options
• Organic materials

Cons:

• Sponge clean only with no removable cover
• Pricey

Made using natural, organic materials, this mattress comes with a twist – it’s really two products in one. One side of The Little Green Sheep Twist mattress is designed to provide firm support, which is recommended by safe sleep experts for babies under 12 months. Once your baby becomes a toddler, you can flip the mattress and use the other side, which is softer and more flexible to make sure your tot has a comfortable night’s sleep.

One of the big advantages with this mattress is it comes in a variety of sizes to fit different makes of cots and cot beds. Another selling point is that the materials used are breathable, hypoallergenic and free from chemicals and toxins. The mattress also comes with a five-year guarantee so should easily last until your child outgrows it.

However, the mattress does not come with a removable cover and is sponge clean only, which can be awkward when dealing with leaking nappies or posseting babies. The Little Green Sheep recommends using its waterproof mattress protector so you will need to factor in this additional cost, which makes the Twist more expensive than some of the alternatives. But parent tester Alexis feels the mattress is worth the higher price tag: “Absolutely love this mattress! It’s comfortable and very well made. My daughter sleeps great. Great quality.”

As a mama who values my sleep, anything that gets my son toddler to have a good night's sleep is a blessing. It doesn't come cheap, but as a mama wanting the best for my little boy I was happy to make that investment. It's free from chemicals and comes in a range of sizes. The best thing about the mattress is that the material is breathable with built in weight distribution.

9. Ikea Krummeler, £49

–Best budget buy baby mattress

Suitable from: Birth | Type: Cot mattress | Interior: 100% Polyester | Size: L120cm x W60cm x D8cm

Pros:

• Great value
• 2 different firmness surfaces
• Washable cover

Cons:

• 1 size only

Swedish furniture retailer Ikea specialises in simple and affordable products and its cot mattress is no different. Priced at a budget-friendly £49, it is significantly cheaper than some of the other options on the market. Although it's a budget and relatively basic mattress, it still has some great features that make it a good choice for your baby's mattress.

The Krummeler is a foam-filled mattress that has 2 different surfaces — one wavy side with medium-firm comfort and a smooth side which is firmer, so you can choose which one is better for your baby.

Other useful features include a removable cover which can be washed at 60°C with a small pocket to keep the zip hidden away from curious little hands.

10. Silver Cross TrueFit™ Reversible Pocket Spring Cot Bed Mattress, £125

– Best baby mattress for a secure fit

Suitable from: Birth | Type: Cotbed mattress | Interior: Foam, pocket springs, polyester pad, natural rubberised coir pad | Size: L140cm x W70cm x H10cm

Pros:

• Double-sided
• True Fit borders

Cons:

• Premium price tag
• 1 size only

When you hear the name Silver Cross, it is probably prams and pushchairs which come to mind rather than mattresses. However, this superior cot bed mattress matches the brand’s reputation for luxury and quality and it comes with a three-year warranty. The product is double-sided, offering different levels of support for your baby, depending on their age. There is a firmer side intended for babies up to 18 months and then a softer side for toddlers.

The pocket spring mattress includes 190 baby springs so it can offer targeted ergonomic support to your child as they grow. One of the main standout features of this mattress is its True Fit borders and square corners, designed to make sure there are no little gaps between the mattress and the cot bed where little limbs could get trapped, posing a safety risk.

The materials used are hypo-allergenic, making it a good choice for babies with allergies. There is also a waterproof layer to protect the interior from getting damp. The outer cover is made using Tencel, a soft, breathable fabric made from recycled eucalyptus that absorbs moisture and helps regulate temperature, and it can be removed and washed at 60°C.

The appearance of this mattress is also a plus point, with charcoal grey piping around the edges and a quilted finish. The Superior mattress is Silver Cross’s mid-range option and it is more expensive than many other options on the market, but many parents will feel the added features are worth the premium price point.

What should I consider when buying a baby mattresses?

Material/type – Mattresses are made from a number of different materials. Foam mattresses are normally covered in a wipe-clean waterproof cover and the higher the density of the foam the firmer it is. Spring mattresses are often more durable and supportive than foam but tend to be more expensive. Pocket springs are the more luxury cousin: each spring is individually wrapped in a cloth pocket, giving excellent support and comfort. Finally there are natural/fibre mattresses. These are eco-friendly, chemical free and tend to be very firm. Again, they are on the pricier side.

Safety – It's important to have reassurance that your baby's mattress is as safe as possible. They should meet 2 different British Standards, look out for these numbers (BS 1877-10 + A1:2012, BS 71772008 + A1:2011 and BS EN 16890:2017) to check the mattress meets the safety standards. The mattress should be a snug fit and there MUST be no more than 3cm between the cot/cotbed side and the mattress.

Size – Sizes vary depending on the product and though there are several standard mattress sizes, you will need to make sure you buy a mattress to fit your specific cot or cotbed. It's recommended that cot and cotbed mattresses are 10cm thick to avoid sagging where your baby sleeps. Travel cot mattresses are usually thinner – your baby isn't expected to sleep on these every night.

Waterproof covers/mattress protectors – Some mattresses come with removable machine washable covers and some of these are even waterproof which makes keeping it clean very handy, especially to clean up any accidents. This also means you don't necessarily need a mattress protector too.

Firmness – A baby's mattress is different to those we might want to sleep on as adults. The risk of a soft mattress is that your baby could roll their face into the mattress and sink into it, reducing air flow. Baby mattresses need to be firm and there is an easy way to test this.

Can I use a second-hand mattress?

If you’re buying a new cot or cot bed, you may find a mattress comes included with your purchase. However, if you are given a cot by someone else or you buy second-hand, you will need to buy a new mattress even if the existing one appears to be in perfect condition.

And if you already have a mattress in your home which was used by an older child, it is still a good idea to replace it. The reason why second-hand mattresses are seen as a no-no is because they have been linked to sudden infant death syndrome (SIDS), which is sometimes referred to as cot death.

There is also the risk a used mattress might be harbouring bacteria or dust mites, which could aggravate any allergies. It is also worth bearing in mind that mattresses do lose their shape over time and a second-hand item is likely to be less comfortable and supportive.

When should I replace my baby’s mattress?

Most cot and cot bed mattresses are designed to last until your child has outgrown his sleeping space and moved into a bed. With this in mind, you shouldn’t need to replace the mattress until you move your toddler into a bed designed for older children.

To reduce the risk of having to pay for another mattress while your child is still small, look for brands which offer guarantees on their products. Some mattresses will come with a five-year guarantee, while others may have a warranty for three years.

You can prolong the use of your baby's mattress by keeping vacuuming it, some vacuums come with special mattress attachments to remove any dust or dirt.
