How we chose the best kids mattresses

When testing and selecting the best kids mattresses, we considered comfort, support, value for money and practical features such as washable covers, allergy protection and water resistance. Our best-buy round-ups are compiled by qualified and experienced parenting journalists using a mix of independent reviews, MadeForMums Awards testing and feedback from our home testing panel and The MadeForMums Club. Every year, hundreds of parents across the UK help us test thousands of products, so our recommendations are based on honest, real-life family use. This is not a ranked list. Instead, each mattress here has been chosen because it stands out for a different sleep need, age group or family setup.

The Simba Hybrid Kids Mattress being tested

Why we chose it: This is our top pick for the best kids mattress overall because it combines the support of springs with the comfort of foam, making it a great all-rounder for growing children.

We moved from a classic sprung children's mattress to this and can truly say my child's comfort levels have increased hugely and she's sleeping in of a morning! My daughter is on the heavier side but she feels truly supported using this mattress. When she sits on her bed it doesn't dip but evenly carries her weight.

MFM Community Manager Dani

What we like

Supportive enough for heavier children
Hybrid design combines foam and springs
Cooling and hypoallergenic
Feels durable and built to last
Comes with a 1-year trial
Environmentally friendly credentials

What to keep in mind

No removable cover

If you want a kids mattress that feels more premium than a basic sprung model, this Simba is an excellent place to start. It uses titanium Aerocoil springs and CertiPUR foam layers to deliver a supportive but comfortable sleep surface, and it’s one that should work well for a wide range of children.

It also earned strong feedback from our tester Dani, who said it offered enough support for her 9-year-old daughter while still being comfortable enough for parents lying alongside at bedtime.

This is a good option if your child has outgrown a shallower children’s mattress or you want to invest in something that could see them through their teen years. It shares plenty of the same features as the Simba Kids mattress, but adds more depth and many more springs for a more substantial feel.

Tester Dani said that extra depth made a noticeable difference to comfort and support, especially for bedtime cuddles and longer stretches in bed.

Emma Original Mattress being tested

Why we chose it: The Emma Original is a versatile memory foam mattress that works especially well for older children and can continue into adulthood.

After releasing the mattress from its vacuumed pack and once it reached its full potential, it's like laying in a hug for your body. You can feel every part of your body snuggly supported and having shared the bed with my daughter on the odd occasion you can't feel the movement from the other person in the bed.

This is a strong choice if you want one mattress that can grow with your child. It isn’t made especially for kids, but that can actually be a plus if you’re buying for an older child or want a mattress that won’t need replacing as quickly.

The four-layer construction is designed to balance breathability, support and stability, while the soft cover can be removed and washed when needed.

Little Green Sheep Natural Junior Mattress Single being tested

Why we chose it: If you want a natural kids mattress without foam or synthetic fillings, this is one of the standout options we tested.

The entire mattress, including the outside cover and quilting is 100% made from natural materials, so it's a great option if you're looking for an organic mattress. It's incredibly well made and feels luxurious.

Instead of relying on springs or foam, this mattress uses coconut fibres and natural latex to create support and bounce. That makes it a particularly appealing choice for families looking to avoid synthetic materials and chemical treatments.

It’s also designed to help regulate temperature through the seasons, so it should keep children comfortable whether the room runs warm or cool.

Stompa S Flex Airflow Mattress being tested

Why we chose it: Its 15cm depth makes it particularly well suited to bunk beds, where mattress height matters for safety as well as comfort.

My first impressions when pressing my hand onto it was that it feels much more comfortable than the previous mattress we used. The mattress itself feels firm and springy and the cover is very soft.

Parent tester Christy, who tested this mattress in her daughters' bunk bed

What we like

Key specsStompa S Flex Airflow MattressBest forBunk bedsPrice£179SizeL190cm x W90cm x H15cm (standard single)TypeFoamFirmnessMedium-firmRemovable coverYes

This mattress layers a soft breathable cover with hypoallergenic fibre and an airflow comfort layer that helps reduce moisture and keep sleepers cool. That makes it a practical choice for shared children’s rooms and warmer bedrooms.

Parent tester Christy also liked the fit on her daughters’ bunk bed, noting that it stayed within the recommended height while still feeling comfortable.

Best for: Cot-to-bed transition

Want to see this content?

Why we chose it: This is a practical first “big bed” mattress for toddlers moving from a cot or cot bed.

The mattress is a perfect fit for my daughter's toddler bed. It has a soft cover with a lovely cloud design. I was pleased to see that the outside cover is fully removable and washable. It simply unzips and is easy to get off and on. My only reservation is that the mattress cover doesn't have a waterproof side.

Parent tester Emma, who tested this in her daughter's toddler bed

What we like

Good transition mattress for toddlers
Firm and supportive feel
Removable washable cover
Breathable outer fabric with cooling fibres
Hypoallergenic and chemical-treatment free

What to keep in mind

Only suitable until your child moves to a standard single bed
No waterproof side on the cover

Key specsSilentnight Healthy Growth Cosy Toddler MattressBest forCot-to-bed transitionPrice£95SizeL140cm x W70cm x H10cm (toddler bed)TypePolyester coreFirmnessFirmRemovable coverYes

If you’re buying for a toddler bed or cot bed, this is a sensible and supportive choice. It’s designed for younger children, with a firm feel and breathable materials to help with temperature regulation.

The main drawback is longevity, as you’ll need to replace it once your child moves up to a standard single.

Why we chose it: This is the best kids mattress here for families who want a more eco-conscious design without compromising on comfort.

From the minute this mattress arrived we knew it was a great quality mattress, it looked so firm and full of thick spongy layers. Amelia absolutely loves her new mattress, it's so soft and bouncy with a gorgeously smooth knitted cover and quilted finish along the top layer.

This mattress stood out for its eco-friendly design and recyclable materials, but it also impressed our testers on comfort and ease of use. The built-in handles make it easier to lift into place, and the layered design aims to support airflow as well as body contouring.

It’s a good pick if sustainability is high on your list and you still want a mattress that feels substantial and supportive.

This mattress is especially handy for younger children or any family dealing with occasional accidents. The washable zipped cover adds convenience, while the anti-dust mite barrier is another practical bonus.

The only real downside is the wait time after unboxing, as it needs several days lying flat before it’s ready to sleep on.

For children with eczema, allergies or sensitive skin, this is one of the more specialist mattresses in the round-up. The anti-allergy treatment and breathable comfort layer are both geared towards creating a fresher sleep surface.

It’s also relatively affordable compared with some of the more premium options here, which adds to its appeal.

If your child wriggles, rolls or changes position throughout the night, this mattress is designed to keep up. The individual pocket springs adapt to posture changes as they move, helping maintain support across the night.

It’s a sensible option for children who don’t stay in one position for long, although it’s less practical if a washable cover is a must-have for your household.

Why we chose it: The anti-slip base makes this a practical choice for active children who tend to bounce or jump into bed.

The standout feature here is the anti-slip base, which helps the mattress stay put even with a more energetic sleeper. That makes it especially useful if your child tends to launch themselves into bed rather than quietly climbing in.

Like the Emma mattress, this isn’t made specifically for children, so it may suit families looking for a more adult-style mattress that can be used for years.

What to look for when choosing a kids mattress

Sleeping position

How your child sleeps can affect which mattress feels most comfortable. Side sleepers often prefer something softer, while back and front sleepers may get on better with a firmer feel.

Mattress type

Kids mattresses come in a range of types, including coil, hybrid, foam, pocket spring and e-pocket. Each offers a slightly different feel, level of support and price point.

Type of bed

Always check what bed the mattress is going on. Bunk beds often need a shallower mattress, especially on the top bunk, while toddler beds and cot beds need different dimensions to a standard single.

Your child’s age and weight

A younger child may suit a mattress that’s designed specifically for toddlers or early years, while older or heavier children may need something deeper and more supportive that they won’t outgrow too quickly.

Firmness

The right firmness depends on a mix of sleep position, body weight and comfort preference. It’s worth deciding whether you want a firmer or more cushioned feel before you buy.

Temperature regulation

Some children get hot at night, so breathable materials and cooling layers can be especially helpful. Foam mattresses can sometimes feel warmer, while hybrid and breathable fibre designs may offer better airflow.

Allergy protection

If your child has sensitive skin, eczema or allergies, look for hypoallergenic materials or mattresses with anti-allergy features. Regular cleaning can also help, and our guide to the best cordless vacuum cleaners includes models with mattress-cleaning attachments.

Bedwetting and accidents

A waterproof surface or removable washable cover can make life much easier if your child still has the occasional accident. For that, the SnüzSurface Max Junior Mattress is one of the best options in this list.

Price

A more expensive mattress can offer better durability and features, but that doesn’t always mean it’s the best value for your family. Think about how long your child is likely to use it and whether features like a washable cover or extra support justify the extra spend.

What type of mattress is best for a child?

The best kids mattress for your child will depend on their age, weight, sleep style and personal preference, so there isn’t one single perfect option for everyone.

Sleep Foundation says a child’s weight can affect how firm a mattress feels. Heavier children may find a mattress feels softer because they sink in more, while lighter children may find the same mattress firmer. In general, firmer models can be easier for children to move around on, while softer models may offer more cushioning.

If you’re not sure where to start, a medium or medium-firm mattress is often a sensible middle ground for school-age children, while toddlers usually need a firmer option designed for their bed size.

Expert tips for helping your child sleep better

Sleep set-up matters, but so does what happens before lights out. Theresa Ross, sleep therapist and clinical nurse specialist in paediatric sleep services at Evelina London Children’s Hospital, says good bedtime routines should be “realistic, simple, not rushed, not longer than 40 minutes, easy for other caregivers to follow, and fit into your schedule.”

She also recommends looking out for signs that your child is getting tired: “Use your child’s sleep cues to give you an idea of when they are tired and start your routine 30 mins beforehand.”

And consistency is key, according to maternity nurse and sleep expert Jo Tantum: “Babies and toddlers love routine, as they feel safe and secure when they know what happens next. It doesn't matter what the routine is, but it must be the same every night – consistency is the key!”
