Quick take
When a Sleep Number air bed stops delivering the sleep comfort you're used to, the fix isn't always a new mattress. The problem may be as simple as a shifted edge or as involved as a pump that no longer inflates both sides. You can replace just the hardware you need, but the options span a wide price range, from a small retainer bar set to a full dual-chamber pump.
Quick take: If your mattress is sliding out of position, start with the Retainer Bar Hardware Set. If the bed won't inflate and you're on a budget, the wired remote motor pump is the middle ground. If you want independent left/right chamber control, either two-chamber pump will do the job, and the NXT03DR costs slightly less.

Product notes
Sleep Number Select Comfort Mattress Retainer Bar Hardware Set of 2
Start here if your issue is position rather than pressure. The Sleep Number Select Comfort Mattress Retainer Bar Hardware Set of 2 sells for $13.99 and is sized as Full XL. Two bars give you the basic pieces to hold the mattress where it belongs. The limitation is scope: this is hardware, not an inflation part, so it won't help with a pump that's stopped blowing. With a Full XL size listed, you'll need that bed size for the retainer bars to be useful. If your bed is holding air but the edge keeps drifting, this is the cheapest possible first step.
Sleep Number Select Comfort Motor Pump Inflator with Wired Remote, Hose EFCS-1
At $75, the Sleep Number Select Comfort Motor Pump Inflator with Wired Remote, Hose EFCS-1 is the least expensive way to add inflation capability in this set. It's a single-hose unit with a wired remote, and it's sold as used and working. The reason to choose it is the combination of price and function: you get a pump without paying for two chambers you don't need. The trade-off is control. The wired remote keeps you close to the pump, and the single hose serves one chamber, so you won't get independent firmness for left and right sides. Choose this when your priority is keeping the repair affordable and you don't mind a wired controller.
Select Comfort Sleep Number Air Bed Pump for Dual Chamber Queen King Mattress
When you need separate inflation for each side of a queen or king mattress, the Select Comfort Sleep Number Air Bed Pump for Dual Chamber Queen King Mattress delivers that capability. It's priced at $331.54, includes two hoses, a wireless remote, and a power cord, and carries the model number SFCS56DR. Choose it when you want the full two-chamber setup. The limitation is the cost: it's the highest price in this group, so you're paying for the dual-chamber capability plus the included remote and hoses.
Select Comfort Sleep Number Air Bed Pump For Queen King Mattress Model NXT03DR
For the same two-chamber job at a lower price, the Select Comfort Sleep Number Air Bed Pump For Queen King Mattress Model NXT03DR comes in at $324.99. It also includes two hoses and a wireless remote, and its color is listed as beige. The appeal is straightforward: you get the dual-chamber inflation without paying the highest price in this set. The limitation is that it's still a used component, and the two things that set it apart are the model number and the beige color, so don't expect a functional jump. This is the pick if you want two-chamber control and a little less money out front.
Final recommendation by use case
If you're still deciding, match the repair to the symptom.
- If you're correcting a sliding mattress on a Full XL bed, buy the Retainer Bar Hardware Set.
- If your pump failed and you want to keep the repair simple, buy the Motor Pump Inflator with Wired Remote.
- If you need independent chamber control and want the lower listed price, buy the NXT03DR pump.
- If you specifically want the SFCS56DR model or a white pump, buy the SFCS56DR pump.
