Every child has unique sleep needs, and their mattress should support these. With bunk beds being a popular choice for kids’ bedrooms, we’ve handpicked the best bunk bed mattresses, perfect for your little one. Shop lightweight yet supportive bunk bed mattresses, perfect for either bunk, with free delivery and a 5-year guarantee.
Our bunk bed mattresses combine all the same sleep features as the rest of our kids' mattresses, such as hypoallergenic, breathable fibres and supportive open coil springs, into a lightweight design perfect for either bunk. Foam and FR-chemical-treatment-free, you can choose either a firm or medium-firm bunk bed mattress to give your child a sleep surface that balances support and comfort.
Why not take a look at our children’s bedding range and find soft, breathable duvets, pillows and bed sheets perfect for keeping little ones snug all night long?
Or if you’re looking to update your beds across your home, check out our full mattress collection with a huge range of premium mattresses perfect for big kids and parents alike.
While most single mattresses will fit comfortably on a bunk bed and provide a supportive sleep surface, our bunk bed mattresses are lighter and better suited to younger bodies sleeping in bunk or cabin beds.
A bunk bed mattress should be the same size as a single mattress, measuring 90cm by 190cm (3ft by 6ft 3in). However, a bunk bed mattress should be thinner than a standard single mattress.
For top bunks, a mattress must not exceed 15cm in depth to ensure guardrails maintain a safe safety margin (at least 16cm above the mattress) in accordance with UK safety standards. For bottom bunks, standard thicknesses of 18cm to 20cm can be used.
