A favourite amongst growing Aussies
We bought a king single mattress for our 6-year-old's big boy bed - planning for the next 10+ years. All I can say is that I now want to throw out our Sealy and buy an Ecosa for our own bed!

Review on behalf of my sons. 2 King Singles for boys 16 and 20 yrs. From delivery to sleeping easy and smooth process. Small issue quickly resolved by customer services. Both boys have gone from innerspring mattresses and transitioned problem free. About to buy a King for us parents now! 😊
