The top layer is made of quilted gel memory foam that contours to your body and provides extra loft. 2. The middle layer is Nectar's patented Lush Foam that evenly distributes your weight and offers the perfect combo of firm and soft that Nectar is known for. 3. The bottom layer is an adaptive hi-core memory foam that supports your body and prevents sinking.Compared to Casper, Nectar provides about one more inch of memory foam, making it extra cushioned for people who need back support or have sharp pressure points.
