Soft vs firm - which is better for your child?

The right mattress will have just the right density to give your child proper support for a good night’s sleep. While a cot mattress must be firm to be safe, kids’ mattresses range from plush to medium to firm to extra firm.

It’s recommended that kids have a firm mattress or a medium-firm mattress. This will give them enough softness for comfort but also enough of a firm feel so that their spine stays aligned in a natural position as they sleep. If you want more firmness and support, a mattress topper can be added. You can extend the lifespan of a mattress by also using a mattress protector.

How to choose the best kids mattress

Choosing a mattress for your child is a big decision. With the right choice, it will support them as they grow older and see them through many a good night’s sleep. Consider these factors to help you pick the right one for your kid:

  • Firmness - How firm the mattress is will determine how much support is received. The right mattress will be soft enough to be comfy but firm enough to fully support the child’s back and growing limbs plus reduce movement and rolling for a comfy night’s sleep.
  • Size - For younger kids, a single bed is a great size for them to get used to a ‘big kid’ bed. For older kids, a king single or double mattress is a great option that they can grow into.
  • Quality - A high-quality mattress is a fantastic investment and one that can be used for years with more than one child. Go with the best mattress your budget can allow.
  • Comfort - A good night’s sleep is a comfy one. Your child’s mattress should have a thick comfort layer for sufficient cushioning and breathable fabrics that keep the body temperature regulated all year round. Some mattresses also have an additional pillow top layer for enhanced plushness.

Trundle bed base and mattress

For sleepovers in small spaces, you can’t go past a trundle bed.

Our Sealy Single Trundle Base is Australian-made and slides out on wheels when the kids have friends staying over. Comfortable, supportive and practical, it’s a fabulous solution for modern families in compact homes.

Is a spring or foam mattress better for kids?

This depends on the needs of the child. A spring mattress uses a spring system to provide skeletal support for growing spines and bones. Pocket spring mattresses have individual coils that can offer even greater pressure relief. A memory foam mattress is firmer and conforms to the body for support, reducing tossing and turning throughout the night. These mattresses are also hypoallergenic and ideal for kids with allergies. Come into an Amart store to see the difference.

What size mattress should a kid sleep on?

If your child is in need of a new mattress, you’re probably wondering what the best size will be for them. It depends on their age. For kids going from a toddler mattress to a bigger bed, a single mattress is typically a great choice at 92cm x 180cm. For older kids who are growing rapidly, a king single or long single will give them the extra space they need. For teens, a double or queen mattress is a top choice and one that they can sleep in for years to come.
