Statistics on the outlook for a certain type and stage of cancer are often given as 5-year survival rates, but many people live longer â often much longer â than 5 years. The 5-year survival rate is the percentage of people who live at least 5 years after being diagnosed with cancer. For example, a 5-year survival rate of 90% means that an estimated 90 out of 100 people who have that cancer are still alive 5 years after being diagnosed.
A hybrid mattress is a mattress that combines two or more of the major construction techniques for a mattress. The most common type of hybrid mattress is a true hybrid, which combines coils or springs with memory or other foams to produce a unique set of qualities.

Memory foam used in mattresses is commonly manufactured in densities ranging from less than 1.5 lb/ft 3 to 8 lb/ft 3 density. The property of firmness (hard to soft) of memory foam is used in determining comfort.
