Comfort	A top layer of memory foam helps reduce the amount of movement from your sleep partner. The Soft model reduces a bit more motion transfer than the Firm model. Phase Change Material (PCM) absorbs your body heat leaving you with a cool to the touch mattress experience.	With a cooling cover and a gel-coated memory foam top layer the Nectar Lush helps regulate temperature to stay cool and in a deep sleep. The top memory foam layer helps provide temperature regulation while you sleep. The PCM gel that has been infused into the surface of this component is known to: help draw excess heat away from the body and retain it in the component itself to help cool the sleeping environment to the optimal temperature Release any retained heat from the component back to the body to help heat the sleeping environment to the optimal temperature.
Support	Our high-quality memory foam adapts to your body size, shape and sleep position to ensure a great sleep no matter which feel is right for you. Support Foam base layer engineered to be highly durable and resilient. We've tested it, and we know it bounces back every time.	The Nectar Lush features an innovative memory foam with a higher density than what is found in traditional foam products. The increased density helps provide superior pressure relief for a plush, floaty rest.The top memory foam layer helps provide cushioning for the body at its most sensitive areas, like the pressure points. This is often described as the much-loved, traditional "memory foam" feel: softness, cushion, pressure relief, comfort, etc. The second memory foam layer, or the transition layer, is intended to help provide resistance against the body as you lay down on top of the mattress. If you were to jump onto your mattress, this layer prevents you from feeling the base support layer of foam. The base support layer is intended to provide solid support for the layers above it. It helps give structure and stability for all of the other components to perform as desired.
