Delivering restorative support with an extra firm feel, the Therapedic Holliway combines top of the line materials with advanced design for an indulgently comfortable result. High end TheraWrap individually encased coils flex and conform independently of each other, resulting in targeted support tailored for your child's unique body shape and movement. At the sleep surface, you'll find TheraCool advanced gel infused foam, which helps to dissipate excess body heat for a cooler night's sleep. Two additional layers of Performance Firm Foam provide excellent support and firm comfort that helps lull your child to sleep and stay asleep through the night. And lastly, the TheraFoam Encased Edge System provides a wider usable sleep surface, offering superior support all the way to the mattress edges. 10 Year Non-Prorated Warranty.
