Bunk bed mattresses FAQs

Is there a special type of mattress for bunk beds?

The only bunk bed mattress requirement is that it be no more than 16cm high. This ensures that the railings on the top bunk can prevent accidents, such as rolling out of bed. Other than that, we're happy to confirm that your child can use any mattress, whether you want to give them the support of pocket springs or the comfort of memory foam!

Although adult mattresses should be replaced every eight years, we recommend replacing a kids' mattress every three years for children between 3 and 10 and every five years for those between 10 and 16. If the child's existing mattress is older than this, we recommend investing in a new bunk bed mattress as soon as possible!
