to see if the power cord is plugged into an outlet that has power and is not
connected to an on/off wall switch. if the Firmness Control

Why does my
Sleep Number
®
setting change?
There are several factors that can contribute to the fluctuations in
a SLeeP nUMBeR
® setting. a Sleep number ® setting is based on the
combination of body weight, volume of air in the air chamber and
sleep position.
• Temperature: An increase or decrease in temperature can cause changes in the
Sleep number ® setting. a heated mattress pad will cause the Sleep number ®
setting to increase.
• Barometric Pressure: Changes in atmospheric pressure related to weather and
altitude can cause your Sleep number ® setting to change.
• Weight: The Firmness Control ™ System acts similarly to a scale; more weight
means a higher Sleep number ® setting. in addition, the way that the weight
is distributed will affect the reading.
• Sleep Position: The more concentrated the weight is, the greater chance the
Sleep number ® setting will be higher (i.e., when you lie on your side). When it is
distributed throughout the chamber more, it is more likely that the Sleep number ®
setting will be lower (i.e., when you lie on your back or stomach).
