Firmness Control
™
System FAQs
Q. Why does my Sleep Number
®
setting change?
A. Your Sleep Number
®
setting is based on the combination of body
weight, volume of air in the air chamber and sleep position. Several
factors may contribute to fluctuations in your Sleep Number
®
setting:
• Temperature can cause changes in your Sleep Number
®
setting.
For example, a heated mattress pad
will cause the Sleep Number
®
setting to increase.
• Barometric pressure related to weather and altitude can cause
your Sleep Number
®
setting to change.
• Weight can affect your Sleep Number
®
setting. The Firmness
Control
™
system acts similarly to a scale. More weight means a
higher Sleep Number
®
setting.
• Different sleep positions can affect your Sleep Number
®
setting.
The more concentrated the weight is, the greater chance the
Sleep Number
®
setting will be higher (e.g., when you lie on your
side). When weight is distributed more evenly throughout the
chamber, it is more likely that the Sleep Number
®
setting will be
lower (e.g., when you lie on your back or stomach).
Q. What do I do if the Firmness Control
™
system doesn’t run?
A.
Make sure the power cord is securely plugged into the Firmness Control
™
system. Verify that the power cord is plugged into an outlet that has
power and is not connected to a wall switch.
Q. I feel the mattress is losing air. What should I do?
A.
Air loss can be caused by an unsecured hose connection, a defective air
chamber or a defective Firmness Control
™
system. First, make sure the
hoses are securely connected to the air chambers. If you do not find any
damaged or loose connections, identify which of the following situations
matches your situation and follow the instructions for remedying your issue.
NOTE: To avoid variations in your Sleep Number
®
setting or level of
comfort, make sure that you are lying in your preferred sleep position
when adjusting and checking your Sleep Number
®
setting.
If you have a dual air chamber bed and suspect only one side of your
Sleep Number
®
bed is getting softer:
• Inspect the o-ring and connectors for cracking or damage.
• Switch the hoses on the air chambers so the left hose (marked with
a white band) is attached to the right air chamber and the right
hose (marked with a blue band) is attached to the left air chamber.
You should hear a click when the hose is securely connected to the
air chamber.
• Fill the air chambers to the appropriate Sleep Number
®
setting(s)
for the person sleeping on each side of the bed.
• Sleep on the bed and monitor the feel of the bed’s firmness on
both sides.
• If neither chamber feels softer over time, you may have had a
loose connection that was fixed when the hoses were switched.
Switch the hoses back to their correct positions and continue to
use the bed as usual.
• If an air chamber feels softer after switching hoses, contact Customer
Service with the results (the issue stayed on the same side of the bed
or it moved to the other side after switching hoses).
If you have a dual air chamber bed and both air chambers are
getting softer or you have a single air chamber bed and feel the air
chamber getting softer:
• Inspect the o-ring(s) and connector(s) for cracking or damage, then
reconnect the Firmness Control
™
system to the air chamber(s).
