When a sleep comfort air bed needs a replacement pump, a near-match in the name is not a useful shortcut. These two Sleep Number choices share Queen/King wording but identify different models: NXT03DR and SFCS56DR. Start with the designation you are seeking, then use listed color, condition, and amount to break the tie. That keeps the decision focused on practical differences rather than assumptions drawn from similarly named pumps.
Quick verdict
Choose the Select Comfort Sleep Number Air Bed Pump For Queen King Mattress Model NXT03DR when NXT03DR is the model designation you are seeking and the lower listed amount is the priority. Choose the Select Comfort Sleep Number Air Bed Pump for Dual Chamber Queen King Mattress when SFCS56DR is the designation you need. The listed difference is $22.80, while color and model identity provide the other clear points of separation.

Product notes
Select Comfort Sleep Number Air Bed Pump For Queen King Mattress Model NXT03DR
The Select Comfort Sleep Number Air Bed Pump For Queen King Mattress Model NXT03DR is the natural selection when NXT03DR is the model designation guiding the purchase. The described set contains one air pump, a wireless remote, and a power cord. Its two hoses are described as serving two chambers, with one hose for each chamber, while the wireless remote operates the left and right sides. Those details make the setup easy to identify among dual-chamber pump choices. A concrete limitation is its used condition; it is also specifically identified as NXT03DR rather than SFCS56DR. That model distinction is the clearest reason to treat it separately from the other pump.
Select Comfort Sleep Number Air Bed Pump for Dual Chamber Queen King Mattress
The Select Comfort Sleep Number Air Bed Pump for Dual Chamber Queen King Mattress suits a decision centered on the SFCS56DR model designation. Like the NXT03DR package, its description names one air pump, one wireless remote, and a power cord. It also uses two hoses, one for each chamber, and the remote is described as operating the left and right sides. This makes it a similarly configured choice in the core pump-and-control arrangement. Its concrete drawback is the $22.80 higher listed amount versus the NXT03DR. The SFCS56DR name also separates it from the NXT03DR, so the two should not be treated as interchangeable merely because their Queen/King wording is alike.
Final choice by use case
- Choose the NXT03DR if NXT03DR is the designation you are seeking, or if beige is the preferred listed color.
- Choose the SFCS56DR if SFCS56DR is the designation you are seeking, or if white is the preferred listed color.
- Use the model designation first and the price second: both pumps are used and include the core air-pump, wireless-remote, and power-cord arrangement, so the named model remains the primary divider.
