The Importance Of Good Sleep

It is common knowledge that getting enough sleep is vital for us to function properly and the same goes for children. Exactly how many hours a child should ideally sleep per night is however still a bit unclear. A study✓ shows that there are discrepancies between the sleep guidelines published by different reputable sources and that there is a lack of clear evidence that can support these recommendations.

No matter how many hours a child needs to sleep exactly, what is clear is the fact that a good sleeping routine matters more than we might think. Research✓ shows that a regular bedtime positively affects cognitive performance such as reading and mathematics in younger children, while another study showed similar results in adolescents with a set bedtime.

Good sleep habits can improve cognitive functions

Healthy Bedtime Routines

An article in The Guardian quotes Dr George Kitsaras, who led an article✓ that has defined a recommended bedtime routine for children aged two to eight:

"Bedtime routines are important family activities and have important implications on children’s wellbeing, development and health"

Dr George Kitsaras

Establishing a healthy evening routine can help make your child fall asleep faster as well as sleep longer. We have gathered some do’s and don’ts when it comes to evening routines based on what some of the experts say: 

✓ Calming activities such as reading a book or taking a bath.
✗ Encourage your child to use technology close to bedtime as the light from the device can suppress the hormones that cause sleepiness.
✓ Drink a cup of Horlicks or other warm beverages.✗ Let your child drink any beverages including caffeine, such as Coca-Cola, coffee or tea, in the evening.
✓ Have them go to the toilet the last thing before they go to bed to try to prevent them needing to go during the night.✗ Eat dinner too close to bedtime as going to bed with a full stomach can delay falling asleep.
✓ Create a safe and cosy sleeping environment for your child, starting with a comfortable mattress.✗ Encourage them to partake in too hectic activities during the last hour before going to bed.

Each sleeper is unique and some of these tips will work better than others. Always consult with a doctor if your child has a persisting sleeping problem.

What To Look For In A Kids Mattress

Children tend to have fewer needs in terms of firmness ratings and materials than some adults who could be suffering from back pain or have other, specific needs for certain mattress features. 

However, that doesn’t mean that we shouldn’t take some time to find the best possible kids pillow and mattress. Even though younger children might not yet have developed physical conditions or needs it is recommended to have them start sleeping on a suitable mattress at an early age in order to prevent any future problems. 

Best kids mattress


Although children may have less personal preferences when it comes to differences in materials such as pocket springs vs. memory foam or latex vs. gel mattresses, materials are still of importance. Some kids are prone to allergies and asthma and it’s important to find a mattress that contains materials that won't provoke a bad reaction while sleeping. 

Organic and natural mattresses are usually a good choice if your child is allergic or sensitive to synthetic materials. Some examples of great materials are:

  • Natural Latex
  • Coir (coconout fibre)
  • Bamboo
  • Horsehair
  • Wool
  • Cotton

If you are still unsure of what materials to look for in a mattress, check for certifications such as CertiPUR-US, GOTS, GOLS and similar, which ensures high-quality materials and low amounts of chemicals that could be harmful to younger sleepers.

Support & Firmness

Here is where prevention for the future comes into play. Even if we still don’t have any back problems we could develop them long-term if our mattress doesn’t provide us with the necessary support for our correct spinal alignment. 

The support of the mattress and the firmness rating often go hand-in-hand, meaning that the firmer the mattress is, the higher support it has. The recommended firmness rating in a kids mattress is quite individual to each person and depends on a few different factors including the weight of the sleeper and the preferred sleeping position among others. 

Keep in mind the sleeping position when looking for best kids mattress

Sleeping Position

Kids normally change their position a lot more times during the night compared to adults but they still tend to have their favourite sleeping position. Depending on whether they sleep on their back or on their side, different firmness is recommended. 

Side-sleepers often benefit from a softer or medium feel as they need their mattresses to “give” more in the area of the shoulders and the hips where most of the weight is placed. Front- and back-sleepers usually need a bit higher firmness in order to give their hip area the support it needs to not sink too deep into the mattress, bringing the spine out of alignment.

Temperature Regulation

Nightly sweats are not entirely uncommon in young children and can sometimes be linked to other health issues. But sometimes kids get overheated at night for no specific reason.

Did you know?
A study✓ showed that from the 6381 children that took part, 11.7% reported cases of nightly sweats.

Children that tend to sleep hot could benefit from a mattress with cooling properties and should avoid memory foam mattresses that tend to retain more heat than other types of mattresses and rather opt for spring mattresses or gel mattresses.

Edge Support

Many mattresses today come with reinforced edge support. It is no secret that many kids toss and turn at night and good edge support could make their mattress last longer, or even prevent them from rolling off the edge in more extreme cases. If your child is an active sleeper it might be worth checking for this feature when trying to find the best kids mattress.

Type Of Bed

Another good thing to have in mind when selecting your kid's mattress is what type of bed it will be used in. Is it a standard bed or maybe a bunk bed? If it will be used in a bunk bed it is recommended to check the height of the mattress and compare it to the bed to make sure it is not too high in order to prevent your child from falling over the edge of the upper bunk. If you are looking for a mattress for an infant you might want to check out our guide for the best cot mattresses.

The best kids mattress for a bunk best should not be too high


The price is of course a very important factor when it comes to choosing the best kids mattress. Since kids often don’t have as many preferences or needs as adults when it comes to sleeping we can sometimes get away a bit cheaper on the mattresses for the younger members of the family. Nevertheless, investing in a good mattress could turn out to save you money in the long run so you should not only look to find the cheapest deal. 

Take the previously mentioned factors into consideration and compare them to the price of the mattress you have in mind. If the price seems fair for the features your child wants and needs it should be a good match. 

Little Accidents

Research has shown that it is quite common for smaller children to sometimes wet their beds, and sometimes even for older kids. If your child has frequent little nightly accidents it might be worth considering getting a waterproof mattress for easier cleanup in the middle of the night. If the accidents only occur occasionally you can also opt for a good mattress protector.

Frequently Asked Questions

What type of mattress is best for kids?

The best mattress for kids is one that suits their needs in terms of support and added features, such as natural and clean materials, firmness, temperature regulation etc. It is individual as each sleeper has different needs and preferences.

How to choose a mattress for kids?

Have a look at its features and compare them to your children's needs. Do they tend to overheat at night? Then the mattress should have some cooling properties. Do they toss a lot? Look for edge support. Try to cover as many of your child's needs as possible and if the price seems fair for what the mattress offers it should be a good fit.

Where to buy a mattress for kids?

Many of the bigger sleep brands offer mattresses for younger sleepers as well. You can browse their webs and do your research but we recommend that you visit their shops as well in order to try the mattress you are interested in buying.
