The Feel This mattress has a medium to medium-plush feel. Dual Memory Foam Layers Two memory foam layers make sure you won’t bottom out. The top layer, made of 3 inches of ventilated gel memory foam, contours to you, sinking you farther into the mattress. Choosing the right mattress will help you achieve restful sleep and assist in maintaining the natural shape of your spine. Memory foam is considered the best type of mattress due to its ability to contour to the body. It molds to the body and reverts back to its neutral form as soon as the exerted pressure is removed. Memory foam beds are a newer type of mattress that have gained popularity for their “customized” feel. Originally created by NASA researchers in the 1970s to provide crash protection for airline pilots and passengers, memory foam is now used in pillows, mattress toppers, and as a comfort layer for multiple types of mattresses. The 12" Premium Memory Foam Mattress from HoMedics by Sinomax is the highest in sleep comfort with a generous 4.5in of memory foam. This design allows for a more natural air flow while you sleep. .
