Is a Memory Foam Mattress Good for a Child?

Memory Foam Mattress Concerns Debunked

It’s time to put your worries to bed...

Memory Foam Sinkage is Dangerous

Memory foam mattresses are designed to contour to the sleeper’s body, providing tailored comfort and support. A memory foam mattress for children is designed for optimum support and will only react to the weight of your child. In fact, this quality minimises disruptions when they toss and turn throughout the night.

Memory Foam is Too Hot

While memory foam of the past had a reputation for getting too hot, new innovations in foam technology have rectified this.

For example, our CoolBaby Cot mattress is constructed with fast-drying Coolmax fabric which reduces heat and moisture build-up to keep them cool. All of our children’s mattress covers are easily removed and machine washable to keep things fresh.

Memory Foam Chemicals are Bad for Children

All of the kid’s mattresses in our range are compliant with UK safety regulations and are completely safe for little ones.

We use breathable nursery foam which has been formulated with young children in mind for our cot bed mattresses, ensuring your baby is safe in bed.

Memory Foam Mattress Benefits for Kids

Memory foam offers a whole host of benefits that can help your little ones sleep well, all night long.

  • Personalised support and comfort
  • Durable, long-lasting materials
  • Dust mite defence
  • Pressure relief
  • Promotes healthy spinal alignment
  • Hypoallergenic
  • Movement absorbing to minimise disruptions to sleep
  • Easy to care for

Another benefit to our mattress collection is that the covers are removable and machine washable to keep them fresher for longer. However, we’d recommend using a mattress protector to guard against any night-time accidents.

How to Choose a Mattress for a Child

When looking for the best mattress for your child, there’s a few key factors to consider;

What is the Best Mattress Type for a Child?

Pocket sprung mattress or foam, which is best? This comes down to your child’s sleeping preferences, their weight and sleeping habits.

Innerspring mattresses tend to be less long lasting and the springs can become uncomfortable overtime. If your child prefers a bouncy feel, opt for pocket springs or a hybrid model which can offer better support.

Age and Mattress Size

Babies and very young children will need a mattress that fits into their cot.

Our cot bed mattresses come in two sizes: W60 x L120 x D10 and W69 x L139 x D10.

As your child grows, they will need a larger mattress that fits on a small single or single bed. However, the more room to stretch out the better and if your child is lucky enough to have a large bedroom, our CoolKids range goes from small single to small double and double mattress sizes.

What’s the Best Mattress Firmness for A Child?

Generally speaking, a medium soft to medium firm mattress is suitable for children. However, the perfect firmness is dependent on your child’s weight and sleeping preference. For example, the heavier the child, the firmer support they will need.

Baby mattresses should not be too soft to keep them safe.

Sleeping Position

The position your child tends to sleep in should have a bearing on what type of mattress you choose. Memory foam is well suited to side sleepers as it provides cushioning around pressure points such as shoulders, hips and ankles.

If your child sleeps on their front, you may want to consider a firmer mattress to minimise spinal curvature.


Dust mite allergies are fairly common among children. If your child has allergies, avoid open coil or innerspring mattresses as they are a breeding ground for dust and mites.

Eco friendly natural latex is a good option, but pricey. The more affordable alternative is hypoallergenic memory foam which provides a barrier against dust and mites.


Everyone wants the best for their children, and providing a comfortable and supportive mattress for sleep is important for their health and wellbeing.

However, a quality mattress doesn’t have to cost the earth. Our baby and children’s mattresses start at just £54.99.

If you have a bigger budget to play with, our CoolKids hybrid mattress combines the bounce and support of springs with the comfort of memory foam. This mix of materials offers optimum breathability and spinal alignment.
