The Von Epica Denali Mattress (like its smaller equivalent, the Von Orchid) is a layered modular mattress, offering up to 18 internal components that can be adjusted to accommodate a wide variety of support preferences. It also allows for adjustments along the distance from shoulder to hips for each sleeper. This is one our best sellers as it has the most amount of design flexibility. Made from resilient, sumptuous layers of High-Density/High-Resiliency Foam and Latex materials, the Denali comes in both plush or wool quilted versions. Because this mattress contains different easily replaceable and adjustable components, it can truly be a lifetime product.
