This mattress has been specifically designed for kids with a modern football design covering every inch of the mattress with a hard-wearing fabric. Designed with 7 individual comfort layers providing extra support. The mattress consists of a European-engineered Bonnell 13.5 gauge open coil spring system, which allows the weight to be distributed evenly across a wide surface to allow your child to enjoy a comfortable and relaxing night's sleep. The mattress has been designed to be dual-sided, so you can flip or rotate the mattress, we recommend doing this every so often to keep it in pristine condition and to enjoy long-lasting comfort. With our new in-house technology your mattress will come vacuum packed making it much more environmentally friendly. We recommend that you do not leave the mattress rolled and boxed for more than 7 days after receipt. The mattress will be delivered compressed, rolled, and boxed, the mattresses do not have side supports, therefore prolonged sitting on the edge of the mattress is not recommended.
