203 cm x 107 cm x 21 cm


Eco Kids mattresses in all sizes boast a range of premium features
unrivalled by other mattress companies.

  • Handmade in Melbourne

    Our staff of experts hand-assembles every Eco Kids king single mattress in our Melbourne factory to ensure that it meets the highest quality standards across the entire range.

  • Better support for growing bodies

    Our Chiro Flex ES spring system is constructed with refined, triple-heat-treated wire and is used exclusively across the range of children’s bed sizes. With each successive kid’s mattress size increase, the coil count goes up as well. As a result, our springs are 60% stronger than those in most king single mattress designs providing unparalleled support as they grow.

  • 100% natural and anti-allergen

    Cotton Australia’s channel-quilted 100% traceable natural cotton provides insulation and maximum breathability with all of our children’s mattress sizes.

  • Free of harmful chemicals

    Our bamboo lyocell fabric is created in an environmentally friendly closed-loop manner. This fabric is OEKO-TEX® Standard 100 certified, so it’s free of dangerous chemical substances and safe for direct skin contact. Soft to touch yet highly durable, our bamboo is anti-microbial and ventilated to keep the body cool, even in the warmest climates.

  • 70% more edge support

    Maxi-Boost’s enhanced edge support provides 70% more support around the mattress perimeter. Extra support means your child is safe from rolling off and offers comfortable back support for sitting and reading at bedtime.
