The Virtuoso 12 King Size Mattress by Magniflex is a true testament to what premium bedding is all about. The Virtuoso mattress is made using only the best materials a sleep system could offer. Artisan workers in Italy take profound pride in the process of making a Virtuoso mattress, one at a time. Each Virtuoso mattress has a winter side and a summer side. The winter side features padding in cashmere, camel hair, merino wool and horsehair. The summer side features padding in linen, cotton, silk, and horsehair. Inside the mattress core, a combination of four exclusive Magniflex foams guarantees an embracing yet supportive level of comfort. To enhance airflow within the core and create specific support zones, a system of differentiated vertical holes are placed to relieve pressure points and keep your body comfortably supported. The way Magniflex workers combine these precious fibers into a structured finished masterpiece for your sound sleep makes each Virtuoso mattress exclusive and excellent.
