Made with smaller beds in mind

All of our toddler mattresses are sized 70 x 140 cm. If your child is a little older than a toddler, then consider our small single mattress range.

Our toddler mattresses are specifically designed, so you can rest assured your little one is sleeping on a comfortable and supportive base – helping to keep them sleeping through the night. View our range here.

Frequently Asked Questions

  • Do toddler beds come with mattresses?

    At Happy Beds, our toddler beds and mattresses are bought separately. When buying a bed, we offer the option of adding a mattress before the checkout process.

  • What sizes are toddler mattresses available in?

    At Happy Beds, our toddler mattresses have a measurement of 70 x 140 cm. This means they will fit perfectly inside a toddler bed.

    If you're looking for something smaller, we have a range of cot mattresses available that have a measurement of 60 x 120 cm.

  • What materials are toddler mattresses available in?

    Our toddler mattresses are made of 3 materials:

    • Open coil spring mattresses: a mattress that contains tightly wound coil springs that run across the sides of the mattress. These mattresses come in a range of firmness ratings.
    • Pocket spring mattresses: a mattress featuring individual pocket springs enclosed in fabric pockets. The springs work independently to offer support in areas of applied pressure.
    • Reflex foam mattresses: a mattress made up of tiny holes that mould to a body shape, offering support. Reflex foam mattresses bounce back to their original shape when not in use.

  • What age is suitable for a toddler mattress?

    The recommended age range for a toddler mattress is 2 - 4 years. Once your child passes this age range, they can move up to the next size; a small single mattress.

    If you're not sure what mattress size you need, take a look at our helpful kids' bed size guide for more information.

  • How long will a toddler mattress last?

    Although a standard adult mattress should be replaced every 8-10 years, children's mattresses may need to be replaced earlier than this, to ensure the mattresses are still supporting their bodies.

    As toddler mattresses should only be used by children aged 2-4, a toddler mattress should last throughout the years your child uses it.
