My Synergy Mattress is made up of components that work in harmony to give you a fabulous sleep experience- hence the name! It also has options! Depending on which feel of the mattress you choose, you'll get either comfort or convoluted foam for air flow and additional comfort. A lumbar layer of my famous Bob-O-Pedic Gel Memory Foam offers plenty of temperature regulation and pressure relief. Finally, an individually wrapped coil system is there for support and conformance. Put that all together and you've got the recipe for a peaceful night!
