At its core, the Anti-Allergy Foam Free Sprung Kids mattress has a medium tension to provide the even support across the body, topped with a layer of smart-fibres which promote a healthy sleeping environment by regulating temperature,  moisture and airflow to keep them cool and dry, and keep the mattress fresh, as well as providing a comfortable surface on which to rest. But the method behind the hypoallergenic madness is the specially designed Purotex treatment; a 100% natural, pro-biotic remedy which fights bacteria, fungi and dust mites - all common allergy triggers.
