Comfort and cooling, combined with the deep compression support of individually encased coils, are the signature features of the FDM 12” Cololing Hybrid. A quilted “Cool to the Touch” PCM Fabric (Phase Change Material) cooling top layer is paired with gel infused memory foam for optimal temperature moderation. A third transition foam layer and a 6” base of Ascension Coils deliver ultimate support and increased airflow for a cooler, more restful night’s sleep.
