Choosing the best mattress for your child is an important purchase and one you’ll want to feel confident about. Kids do most of their growing at night so, just as you wouldn’t shove any old shoes on their feet without checking they were comfy and fitted well, you should ensure that their mattress will offer great support at night and continue to support them as they grow. 

Here at Mumsnet, we know how important sleep is for parents. Drawing on the expertise of over 8 million Mumsnetters, we've got you covered with tried-and-tested recommendations for every stage. We helped you choose the best cot mattress for your little one, showed you our pick of the best swaddles and gave you inside knowledge on gadgets like white noise machines to save your sleep - and your sanity - in those early days.

When we set out looking for the best kids’ mattresses, we started with the most important people - parents who’ve been there and know which mattresses are really worth their salt. In our search for the best mattresses for kids' beds and bunk beds, we trawled the Mumsnet forums with a fine-toothed comb looking for Mumsnetters that were so happy with their mattress buys that they wanted to recommend them to others - as well as information on which mattresses to avoid.

We also took note of expert and consumer reviews - how pleased customers were with their mattresses and also how well the company responded if parents decided the mattress wasn’t for them after all. Mattresses are one of those purchases where the aftercare really matters and longevity is key. 

So which mattresses do parents really rate? After extensive research, these are the best mattresses for kids. 

1. Best overall mattress for kids: Silentnight Healthy Growth Junior Mattress

Silentnight healthy growth mattress

RRP: £229.99 | Buy now from Bensons for Beds

Key specs

Type: Coil sprung | Depth: 21cm | Tension: Medium | Sizes: Single, small double

What we love

  • Five-year guarantee
  • Designed to support your child's growth

What to know

  • Single-sided so can’t be turned but you should rotate it

What Mumsnet users say

"We got DDs from Bensons for Beds. It's a standard single bed with a mattress specifically designedfor children - it's supposed to offer the right support for a growing child and I have to say it's fantastically comfy." (Recommended by Mumsnetter BabyMoonPie)

Our verdict

Designed to give the best support for kids’ growing bodies, combined with great quality and of course, a comfy nights’ sleep, Silentnight’s Healthy Growth Junior Mattress is our pick for the best overall kids’ mattress. 

Traditional bonnel springs provide zoned support at the back, hips and shoulders, and a medium-firm tension helps align the spine. Hypoallergenic and breathable fibres keep your child cool during the night and also help those with allergies sleep better. What’s more, the mattress is made from fibres produced using recycled bottles, so you can sleep a little easier knowing that you’re taking care of the earth too.

2. Best budget mattress for kids: Jay-Be Open Foam-Free Sprung Mattress

Jay-be kids' mattress

RRP: £90 | Buy now from Amazon

Key specs

Type: Coil sprung | Depth: 16cm | Tension: Medium | Sizes: Single, European single, small double, shorty

What we love

  • Can be used with a bunk bed or high sleeper
  • Excellent price for those on a budget
  • Five-year guarantee
  • Hypoallergenic

What to know

  • Reviews suggest it’s more suitable for younger children - teens may not find it quite so comfy

Our verdict

A decent mattress for under £100 is quite a rarity so we were impressed with how good this Jay-Be mattress is.

It’s a basic sprung mattress, which has coil springs to support the body evenly and three comfort layers on top that offer an open-cell structure for maximum breathability. But it isn't the most plush of the mattresses, and some reviews suggest it's best suited to toddlers and younger children. However, for its price, we think it does an excellent job and it’s guaranteed for five years too. 

3. Best European single mattress for kids: Simba Hybrid Essential Mattress

Simba hybrid mattress

RRP £466.95 | Buy now from Simba

Key specs

Type: Continuous coil and memory foam | Depth: 25cm | Tension: Medium | Sizes: Kids, single, European single, small double, EU double, EU queen, king, superking 

What we love

  • Keeps them cool in bed
  • Hybrid materials
  • 200-day trial
  • 10-year guarantee
  • Should last from age three to adult

What to know

  • No built-in mattress protector - a Simba one costs £90
  • Quite expensive

What Mumsnet users say

"Simba do European size mattresses.. amazing for backs too!" (Tried and tester by Mumsnetter BlahDeDah45)

“I have a Simba and love it! It's so comfy like a giant hug.” (Recommended by Mumsnet user, Mucky1)

Our verdict

Available in every bed size imaginable - including EU single - this hybrid mattress from Simba impressed us on almost every front. Firstly, it’s a bed in a box, so delivery is easy, and getting it up the stairs is no problem either. Then you just sling it on the bed, unpack it and wait for it to ‘rise.’ If you’ve been deciding between a memory foam or sprung mattress, this gives you a bit of both. The feel of it is really comfy, with all the support of springs and all the cosy softness of memory foam. It’s also designed to have edge support, which will help prevent your child from rolling out of bed.

The mattress has five layers of open cell foam, springs and memory foam, and is engineered with more than 1,500 Aerocoil micro springs to support even the most fidgety of children in bed. On top, a layer of Simbatex foam, made with an open structure and heat-wicking graphite, helps to keep your child’s temperature regulated while in bed, even on hot nights. 

Best of all, the Simba mattress comes with a 200-day free trial, so you have months to decide if it’s right for you, and it also has a 10-year guarantee. You can’t say fairer than that. 

4. Best premium mattress for kids - Soak and Sleep Pillowtop Mattress

Soak and sleep pillowtop mattress

RRP: £1,250 | Buy now from Soak and Sleep

Key specs

Type: Pocket sprung | Depth: 30cm | Tension: Medium | Sizes: Single, small double, double, king, superking, emperor 

What we love

  • Temperature-regulating filling
  • Super comfortable

What to know

  • Expensive

What Mumsnet users say

"Highly recommend soak and sleep mattresses we've had ours a good few years. We have a mix of classic and the one with memory foam topper." (Recommended by Mumsnet user womaninatightspot)

Our verdict

For a truly dreamy nights’ sleep, Soak and Sleep’s impressive pillowtop mattress is an investment your child will enjoy for many years. Handmade to order by expert craftspeople at the company’s factory in Yorkshire, the company have been making beds and mattresses since 1840. This one contains 8250 pocket springs, which move independently of each other, contouring precisely around the body to provide ultimate comfort. 

While price is an obvious drawback, if you’re looking to splash out on a premium mattress that will last a lifetime, Mumsnetters agree you can’t go wrong with Soak and Sleep.

5. Best natural mattress for kids: Little Green Sheep Natural Junior Mattress

Little Green Sheep mattress

RRP: £294 | Buy now from John Lewis

Key specs

Type: Foam | Depth: 13cm | Tension: Medium-firm | Sizes: Single

What we love

  • Available in a European size and custom sizes
  • Natural and hypoallergenic

What to know

  • Mattress can only be sponged clean (mattress protector available separately)
  • Quite thin at 13cm

Our verdict

If a natural approach is important to you, look no further than Little Green Sheep, which eco-conscious Mumsnetters rate highly.

While their cot mattresses are a particular favourite among parents, their single mattress is suitable from 12 months to 12 years. And you’d be more than happy to put a toddler to sleep on it thanks to its coconut coir filling, wool and natural Latex, and absolutely no nasties whatsoever for them to be breathing in.

One of the things we really love is that this mattress is available via the Little Green Sheep website in a European size, so will fit an IKEA bed, but you can also have it made in any customised size you want to fit any space at all. 

6. Best mattress for teens and tweens - IKEA Valevag 

IKEA Valevag

RRP: £169 | Buy now from IKEA

Key specs

Type: Pocket sprung | Depth: 24cm | Tension: Firm or medium-firm | Sizes: Single, small double, double, king, superking

What we love

  • Affordable price
  • 10-year guarantee
  • Arrives ready rolled

What to know

  • One-sided so can’t be flipped

What Mumsnet users say

"IKEA for sure. We have these on our bed too. Just take care to get the correct length (they sell uk or euro length). You can even pick them up in the car as they come rolled and vacuum packed. Fitted two in a Peugeot 206!" (Recommended by Mumsnetter MotherOfCrocodiles

"My late teen has the Hovag, and as I said, it's still comfy after four years' use. Used daily (sometimes for 16-18 hours a day!)" (Tried and tested by Mumsnet user hotchocdrinker's sleepy teen)

Our verdict

It’s a stereotype supported by science - teens and tweens need more sleep, and often at different times to the rest of the family. As they’ll likely be spending a lot of time in their bed, it makes sense to pick a great mattress for older kids and teens. You can count on IKEA for affordable, simple, good-quality furniture, so it’ll come as no surprise to find an IKEA mattress in our round-up. Valevag (formerly Hovag) is a basic pocket-sprung mattress with a generous foam layer to add extra comfort and support. 

The mattress has a reinforced edge, so sitting on the edge won’t damage it - perfect for teens who tend to use their bed as a gaming chair, homework area and hangout zone as well as for sleeping. 

7. Best easy-to-clean mattress for kids - Marks & Spencer Easy Clean Mattress with Removable Cover

M&S easy clean mattress

RRP: £249 | Buy now from Marks & Spencer

Key specs

Type: Open coil | Depth: 20cm | Tension: Medium | Sizes: Single

What we love

  • Washable cover
  • Fabulous delivery and customer service

What to know

  • Some reviewers say it’s not suitable for use with a mattress topper

What Mumsnet users say

"If you can source M&S ones, I'd recommend them." (Recommended by Mumsnetter JudySmallweed

Our verdict

Even the most reliably potty-trained children can have accidents, and this mattress from Marks and Spencer has a removable cover, giving you peace of mind and a great nights’ sleep for everybody. The cover is made from breathable fabric and the mattress has an antibacterial surface to ensure it’s hygienic and stands the test of time. 

Mumsnetters love M&S’s great quality mattresses, and we think this easy-clean design is a godsend for parents of young children. 

8. Best kids’ mattress for bunk beds: John Lewis & Partners Deep Open Spring Water-Resistant Bunk Bed Mattress

John Lewis bunk bed mattress

RRP: £150 | Buy now from John Lewis

Key specs

Type: Open spring | Depth: 15cm | Tension: Medium | Sizes: Single

What we love

  • Very well priced
  • Seven-year guarantee included
  • Water-resistant

What to know

  • Less thick than some mattresses, but that’s often necessary for bunks

Our verdict

Buying a mattress for a bunk bed can be tricky as you need to know that the mattress won’t be so tall that it comes up above the sides of the bunk. This mattress is specially designed for bunks and is just 15cm thick so will fit snugly into any bunk frame. 

The mattress has an open-coil spring system and is filled with polyester, white recycled cotton and wool to give squishy yet firm support. There's a water-resistant layer which adds protection against accidents - not to mention peace of mind. It also comes with a seven-year guarantee and the peace of mind that a John Lewis purchase always brings in terms of quality and customer service. 

9. Best memory foam mattress for kids - Bedzonline Memory and Reflex Foam Mattress

bedzonline memory foam mattress

RRP £97.99 | Buy now from Amazon

Key specs

Type: Memory foam | Depth: 15cm | Tension: Not stated | Sizes: Single, small double, double, king, superking

What we love

  • Hypoallergenic materials
  • Great price 

What to know

  • Needs 72 hours to expand before use

What Mumsnet users say

"They've been fab. Both are going strong several years of daily use later. DD says it has helped with Hypermobility aches and pain (which I had told her it would!!) And she didnt notice it being any hotter in the long run. DS did eventually get an upgrade as he got a specialist adjustable bed second hand that incidentally came with a tempur mattress. That's a beautiful mattress too. His budget one is doing currently still doing service with my sister who is now converted to memory foam too." (Tried and tested by Mumsnetter Caramellatteplease)

Our verdict

Using body-moulding technology developed by NASA, memory foam is heat and pressure sensitive, responding to your child’s body shape and providing amazing comfort and support. This mattress also has a layer of reflex foam at its base, offering extra stability. 

This mattress is delivered rolled and vacuum packed, making it easy to manoeuvre. However, it requires 72 hours to fully expand after opening, which might not be very convenient - especially if you’re short on space.  

10. Best double mattress for kids - Silentnight 3-zone memory foam mattress

silentnight 3-zone memory foam mattress

RRP: £178.49 | Buy now from Amazon

Key specs

Type: Memory foam | Depth: 18cm | Tension: Medium | Sizes: Single, EU single, double, EU double, king, EU king, superking 

What we love

  • Anti-allergy
  • Tailored comfort

What to know

  • The mattress can’t be cleaned, so it’s best to get a mattress protector
  • Some reviewers found the initial smell unpleasant

What Mumsnet users say

"The Tri zone silent night one is a good price and so comfy." (Recommended by Mumsnet user Abibranning

Our verdict

Whether you’re buying for an older child or you find yourself squeezed into a single bed to soothe a younger one most nights, many Mumsnetters swear by double mattresses for kids. This memory foam mattress from Silentnight has 3 comfort zones which respond to your body and relieve pressure across your shoulders, back and hips. Because the mattress moulds to your body, it’s comfortable both for you and your child to sleep on - although it can’t do anything about late-night wriggliness. 

What’s more, the mattress includes anti-allergy purotex fibres, which work to protect against dust mites. With a medium tension, it’s not too soft and not too firm - perfect if you or your child is a side-sleeper. 

How do I choose the best kids' mattress?

Many of your decisions will need to be made before you even start shopping, so the main things for you to consider are:

Size

Before you look at the different types of springs, fillings and foams, you need to know that your mattress is going to fit your child’s bed.

If they’re about to transition into a bigger bed, you'll be pleased to know that most beds and mattresses are a standard size. However, it’s always worth measuring your frame properly to ensure you buy the correct mattress length and width.

Be aware that, while you’ll probably be shopping for a standard single once your child is out of a cot bed or toddler bed, there's also such as thing as a ‘shorty,’ which is shorter than your average single bed, as well as European singles which are a bit narrower.

Remember to also check the depth of the mattress. While most mattresses will sit in a box frame, the mattress will need to be thinner if it's a bunk bed or high sleeper so that your child doesn't roll over the barrier and out of bed. 

Type

The choice for children is pretty much the same as for adults. You’re looking at springs (pocket spring, open spring and coil spring), latex or memory foam, or a hybrid of springs and foam. 

Spring mattresses offer good bounce and support, while memory foam is softer and typically hypoallergenic. Latex retains its firmness well, so can be good for children's beds, however a hybrid mattress offers both the comfort of latex and memory foam but the bounce of a spring mattress. 

How your child sleeps

Do they tend to run hot at night? Look for springs with breathable covers. Or do they wake up with chilly extremities? In which case, memory foam might offer more cosiness.

And how much do they move around in their sleep? Generally speaking, memory foam is good for fidgeters as they’re more cocooned and less likely to wake themselves up.

Also consider how often you end up in your child’s bed to settle them. It might be worth getting a larger mattress if you regularly end up spending a few hours in it with them.  

Allergies

If your child suffers from allergies, a memory foam mattress is the best bet as it doesn't trap dust and dust mites as easily as spring mattresses. Look for one that is labelled as hypoallergenic.

Mattress protector

If your child is toddler age, check whether the mattress comes with a removable, washable cover as accidents definitely can happen. 

Once you’ve worked out the measurements and decided which type of mattress your child needs, go and try some out. Check that it's comfy, not too bouncy, won't lose its oomph too fast, and that your child will feel safe and secure on it during the night. The mattress you choose should also adhere to UK safety standards.  

What is the best type of mattress for a child? 

Experts, rather unhelpfully, disagree on whether springs or foam is best for growing children. Some claim that springs are best because memory foam lacks breathability and also moulds to a child's body, which isn’t good when their body is growing so fast, while others feel memory foam offers superior orthopaedic support.

If you’re going for springs then a pocket sprung mattress is best and most supportive option. The higher the spring count, the more support there is. Also look at the gauge - the lower the gauge number the thicker the springs and the firmer the feel. 

Tension is also worth considering and is usually described as either soft, medium or hard. The only real way to tell what’s best for your child is to let them try different mattresses out and see what they prefer.  

What mattress firmness is best for a child?

Firmness will ultimately come down to how your child sleeps and what they feel most comfortable laying on. Lots of children like the cosiness of a soft mattress, while others will prefer a medium-firm option if they move about at night.

A medium or medium-firm mattress will suit most kids when it comes to comfort and structured support, particularly for their spine, however this may be even more important as they hit the teen years.

How thick should a toddler mattress be?

Once your toddler is out of their cot (at around 18 months to 36 months), you should use a kids' mattress, which tends to be 12 to 20cm thick. What’s important is that the mattress offers the correct support and won’t come up higher than the bed’s sides. A mattress that's too thick could lead to your child rolling out of bed.

What's the best mattress for kids?

Mumsnets' best mattress for kids is the Silentnight Healthy Growth Junior Mattress. It's a brilliant all-rounder that makes bedtime comfy and cosy, while it's clever design supports kids' growing bodies while they sleep soundly - all for under £250.

How we chose our recommendations

Mattresses are a big investment and even budget models don’t come cheap so we wanted to be sure that the ones we recommended came with real-life recommendations.

We went to the Mumsnet forums in the first instance to find out which brands and models Mumsnetters rated most highly. We then cross-referenced that list with the mattresses that had one industry awards and accolades.

We then created a shortlist of those that made it onto both lists, and scoured the internet for customer reviews to tell us more about each one. Using those, we whittled our choice down to 10, which we think offers something for every little sleeper.
