You have probably seen the ads where a man in a white labcoat drops a black bowling ball on a mattress and none of the bowling pins are disturbed.  This, of course, is a simple way to show that your partner could be doing jumping jacks on one side of the bed and you’d never even know.

How is this possible? The answer is the revolutionary pocket coil technology found exclusively in Simmons Beautyrest mattresses. As you will see in the diagram below, the springs are not attached to one another, rather they rest independently in their own “pocket.” This allows enough ‘give’ so that when you put pressure on the mattress, on the coils you are touching are affected, while the rest of the bed remains still.
