Our Cool Kids Pocket Sprung Memory Foam Mattress features a top layer of memory foam offering additional comfort for your sleeping child. This sits upon a highly supportive & durable foam base. This 15cm deep mattress is encased in a Coolmax® cover which is made using advanced cooling fabrics for moisture dispersement & a cool sleep surface. The cover is zipped for easy removal & machine washing at 40ºC. The 3cm memory foam layer provides comfort & support for your growing child & works in harmony with their body to ensure that they are sleeping in the correct anatomical position. Pocket springs provide even further support as they respond to changes in your child's sleeping position. Both of these elements work perfectly together & reduce the need to toss & turn, creating a deeper & more restorative sleep for their active mind & body. The Coolmax® fabric cover provides enhanced breathability for your child's mattress differentiating it from other more common polyester covers. This cover is made from fast drying & breathable fabrics which resist fading, shrinking & wrinkling. The Coolmax® fibres reduce heat & moisture build up, meaning your child's body stays cool & dry throughout the night. Manufactured in Yorkshire, Engl&.
