What is a good size mattress for kids?

It is what most people are not getting enough of, and it can be a touchier subject for families with little ones. As bedtime tantrums can often disturb our nighttime routine. 

As kids grow, regular and quality sleep is especially important for their healthy development. Whatever the age that will help them sleep through the night is finding the rightmattressfor thebed. There are many different types and when deciding it can be overwhelming to work out which is the best.  

Well, you know that children will need more sleep as they grow and develop,  but how much is enough. There could be poor side effects if the children do not sleep such as tantrums and outbursts, heightened emotions, and difficulty concentrating.  

There are many bestmattressesfor a child here are a few examples where I  will explain the pro and cons of each of them.

Spring or open coilmattress 

The open coilmattress is made up of wire coil and makes a decent quick fix,  which is cheap and cheerful. However, it can be uncomfortable over time with every use, themattresswill become sagging quicker and will develop an irritating squeak. But with little one’s squeaky springs are best avoided.  

Pocket springmattresses 

The next from open coilmattress is pocket sprungmattress that is made from individual springs that are enclosed in their own fabric pocket. Thismattress will provide better and more targeted support for the different parts of the body.  


The latexmattress is often chosen for its hypoallergenic properties and eco-friendly credential. However, thismattresscan be more on the expensive side.  But this mattress would be great for children that suffer from allergies, also not going to be so great if you are on a budget.  

Memory foammattresses 

The memory foammattress can mould into the shape of your body, this will help you maintain a natural spinal alignment and also provide pressure relief. This mattress is also made to be long lasting and is so worth the investment! 

Memory foam will be a great choice if your child tosses and turns throughout the night as thismattress also has a movement absorption ability.  


This hybridmattressis a combination of two or more types ofmattressesin one. It combines the pocket springs with the memory foam comfort layers. As the hybridmattress can solve a range of sleeping problems.  

So, what is the best type of mattress for kids? 

Here are the main factors buying amattress for a kid or baby is about which you should think. 


Standardmattress size for babies and children  


D- W60 X L120 x D10  

This is the standard size cotmattress that are designed for babies.  Cot bedmattress 

D- W69 X L139 X D10  

This is perfect for babies and small toddlers. This cotmattressis designed to fit  a lager cotbed

Small single sizemattress 

D- 76 X 190cm  

Thismattressfits a smallbed for small children, which is great for kids that are  just out from toddlerhood.  

Single sizemattress 

D- 90 x 190cm  

A singlemattress that will be suitable inbeds for growing children and teens. 

Small double size mattress  

D- 120 x 190cm  

Thismattressis suitable inbeds for teenagers or children that would like some  extra room. This small doublemattress can provide a stretching space for a  more comfortable night sleep.  

Double sizemattress 

D- 135 x 190cm  

When having a larger room, a singlebed would look out of place or you must share abedwith a sibling. But you can treat your older child or teenager to a  luxurious sleeping experience, so a doublemattressfor theirbedwould be a  great choice.  

The firmness of themattress depends on the way your kids sleep. But if you would like to know then generally a medium-soft or medium-firm would work well for most children. This provides a good balance between comfort and support for them.  

Also, remember the heavier the child then the firmer the level of support will be needed in themattress.  

Mattressthickness is not important in comfort for children however, the mattress thickness can affect the height of the child’sbed. If it's too high then it could be difficult for them to come in and out of bed, but it could also be a  safety risk as the toddler could fall out ofbed during the night.  

When thinking of the density then memory foammattress is good because it refers to the weight and volume of themattress that is measured in kg/m3.  

The next part will be hard when deciding on themattress for kids which is durability. So, on one hand, you would like to buy amattress of good quality that will last longer, but your child can grow out of themattressat some point. 

As I mentioned before a memory foammattress is an exceptionally durable material that can manage the rough tumble and more when it comes to kids it can withstand all. And it is surprisingly affordable.  

Finally, the last few things that I would like to mention is themattress cover the price which would be the main concern when having little ones. As kids can be a mess it's something that can be avoided so finding amattress that comes with covers that are removable is essential. Pricing is usually the deciding factor for themattressthat it should be affordable, as most families on a budget would be compromised with themattress’squality.
