Most people sleep on a bed that's too firm, resulting in excessively high pressure points. These pressure points cause discomfort along with tossing and turning throughout the night in an effort to get comfortable.
Over the years, as new Sleep Number® bed models have been introduced, they have been subjected to in-house Xsensor® pressure point testing in comparison with leading innerspring mattresses. The Xsensor Pressure Mapping System measures the interface pressure between a body and the surface on which it is lying, using a measuring sheet comprised of 684 individual measurement points. The result is a computer-generated pictorial representation of how the surface being tested conforms to the body, the location of interfacial pressure points between the surface and the body, and the relative degree of severity of such pressure points.
There is significant literature in the sleep science field, backed up by third-party clinical studies, to the effect that sleeping comfort is impacted by the frequency and degree of severity of pressure points.
Specifically, increased frequency and degree of severity of pressure points results in increased body movement (tossing and turning) that reduces sleep quality.
The Xsensor pressure point tests conducted by Select Comfort™ have consistently demonstrated that Sleep Number beds can reduce the number and the severity of pressure points as compared to innerspring mattresses. These tests also have consistently demonstrated that pressure point frequency and severity generally decrease as Sleep Number beds are adjusted to softer firmness settings (such as a Sleep Number 30).
