Last updated: 11.05.2021 9 Min.

Having a good mattress that suits your body and your needs is great and all, but what if you have a baby, toddler, or young child?

Are there specific cot mattresses you need to consider? Do baby mattresses differ? What about health & safety?

Children generally sleep better than babies, but this does not mean we should underestimate the importance of a suitable mattress.

After all, a bad baby mattress can lead to back problems further down the line and well into adulthood.

So choosing a good cot mattress is essential.

We'll guide you through some of the best cot mattresses available in the UK and help you choose one that's perfect for you and your little one.

Choosing the right mattress for young children

Children under the age of 6 generally require a baby or cot mattress.

Like adults, children need quality bedding and a quality mattress that meets their needs.

A good mattress for young children will provide excellent support by adapting to their body without creating painful or uncomfortable pressure points.

Importantly, the mattress should support the spine and provide for healthy spinal alignment.

This is essential for children in the growth period.

Children will rarely complain about back pain at a young age, but a low-quality mattress may lead to back problems years down the line and only emerge in adulthood.

A good mattress will also promote quality sleep, which is key to your child's physical and mental recovery.

This will allow for a better capacity for concentration, memorisation, and learning during the day.

Criteria to consider

Finding that perfect fit for your baby or young child shouldn't be too difficult, but there are a few criteria you need to consider.

These are important to ensure that the cot mattress you choose is the best to aid your little one's development.

Size

Of course, choosing the right mattress size for babies and children is important.

Your child will grow very quickly in the first few years, and you certainly don't want to have to buy a new mattress every year.

We would recommend cot mattresses that fit the 60 x 120 cm or the 70 x 140 cm dimensions.

These are the most common dimensions that are small enough to be suitable for a young child and large enough to accommodate a growing child.

As your child grows, you can switch over to a 90 x 190 cm single mattress, which you can keep well until adulthood.

Materials

Baby mattresses can be made from various materials, including pocket springs, coir, natural latex, or memory foam.

Natural and organic materials are great as they tend to be anti-allergy and don't contain harmful chemicals, but even certified memory foam mattresses can be free from toxins.

The material you choose is also largely influenced by your budget, as natural and organic mattresses are often much more expensive.

Firmness

Firmness is an essential aspect to consider when choosing a mattress for your baby or toddler.

You need a mattress that offers good support but is also very comfortable.

You're better off choosing a medium-firm to firm mattress, which will adequately support spinal alignment and aid healthy bone development.

Generally, newborns require firm mattresses.

Toddlers will be more comfortable on medium-firm mattresses.

Firmness

Breathability

Breathability is vital.

Not only does good airflow help to keep your little one cool and comfortable for a better night's sleep, but it also helps in terms of hygiene and prevents the formation of mould.

The mattress cover should also be breathable and allow for good air circulation.

We would also recommend choosing slatted frames as these can aid in keeping the cot mattress well-ventilated.

Certifications

Health and safety may be important for adults, but this is even more so with cot mattresses.

We recommend that you favour anti-allergenic materials free from harmful substances, such as dichlorobenzene, nitrosamines, or formaldehyde.

This will allow for easier breathing and avoid the risk of allergies.

Also, look out for mattresses that have been certified by external testing institutions like OEKO-TEX.

For example, mattresses that carry the OEKO-TEX-Standard-100 certification are guaranteed to be free from harmful substances, toxins, and dangerous chemicals.

Hygiene

Children are very vulnerable to allergies.

Sme mattresses offer anti-mite, anti-bacterial, or hypoallergenic technologies.

Of course, breathability and certifications that guarantee the mattress is free from harmful chemicals are also important.

It's also a good idea to make sure you invest in a waterproof mattress or a mattress with a washable cover.

You could even consider a waterproof mattress protector.

This will help protect the mattress from moisture, spills, or stains and elongate the mattress's lifespan.

We've given some recommendations of our favourite cot mattress protectors below.

Choosing your baby's bed

While choosing the right mattress for your baby or young child is important, you also need to consider the bed frame.

This will significantly affect your choice of mattress as well.

There are no right or wrong choices, and what you end up choosing largely depends on your budget and personal preference.

Moses baskets

Moses baskets, cribs, or co-sleepers have been specifically designed for newborn babies.

These take up much less space than a cot and are great if you have a smaller room and want your child sharing the room with you - which is recommended for the first six months.

Moses baskets can also be carried around from room to room, which can be convenient.

But, you will have to invest in a crib mattress and then re-invest in a cot mattress as your baby grows.

Cots

Newborns don't have to sleep in a Moses basket or crib and can be quite comfortable in a cot as well.

This is handy as you can buy a cot and cot bed mattress once and then won't have to re-buy a new mattress or frame as your child grows.

Baby mattresses can be expensive if you end up having to repurchase them again and again as your child grows, so it's a much cheaper and more sustainable option to invest wisely the first time around.

We'd also recommend a cot with slatted frames, as this will help with airflow and keep your baby's cot mattress well-ventilated.

Older children

A child can comfortably sleep on an adult mattress from the age of 5 or 6, but it is essential that this mattress is of good quality and can adapt to your child's body as it grows over the next ten or so years.

We've included some of our favourite adult mattresses below, which can be good choices for your growing child.

These are all high-quality mattresses that allow for good airflow, provide adequate support, and are very comfortable.

They're also all available in the 90 x 190 cm single size, which is a good size for most children and teenagers.

Conclusion

In general, you need to consider the health, safety, and development of your child.

The ideal cot mattress will offer comfort and support while aiding spinal alignment and healthy bone development.

You'll be good to go with any of our recommended mattresses.

Don't forget that bed-in-a-box mattress brands, like Eve, all offer risk-free trial periods.

Frequently asked questions

  • What size are baby cot mattresses?

    Cot mattresses are available in a number of different dimensions. 

    The most common sizes in the UK are:

    • 120x60cm
    • 140x70cm

    You'll also find smaller mattresses available that will fit wicker baskets and prams and can be used as travel cot mattresses.

  • Can I buy cot mattresses on Amazon?

    Yes, Amazon is one of the best places to buy cot mattresses.

    Many of the bed-in-a-box mattress brands stick purely to adult mattresses.

    Many of the brands we recommend can be purchased online via Amazon.

  • Do I need special bedding for my cot mattress?

    Yes, you'll need to invest in bedding for your baby or young child. 

    You'll need to consider mattress protectors, sheets, duvets, and even pillows and pillow covers.

    Most large-scale baby stores sell these, both at retailers and online.
