When your Sleep Number bed's firmness control stops holding air or the remote won't communicate with the pump, you don't want a whole new mattress. You need a replacement pump that works with the dual-chamber setup. The Select Comfort Sleep Number Air Bed Pump for Dual Chamber Queen King Mattress is a used replacement unit aimed at exactly that problem.
Quick verdict
At $331.54, this SFCS56DR pump is a direct replacement for a dual-chamber Sleep Number system. It comes with a wireless remote, two hoses (one for each chamber), and a power cord. The seller also includes a two-year warranty and an option to trade in your broken pump and remote. If you're comfortable buying used, this is a practical, price-clear replacement path.
Who it suits
This pump suits anyone with a dual-chamber queen or king Sleep Number bed who needs to replace the inflator pump. Because the remote operates both left and right sides, it fits households where two sleepers want different firmness settings. It's also a good match if you want a wireless remote rather than reaching for a wired controller.
What stands out from the listed details
The SFCS56DR is described as a genuine Select Comfort Sleep Number dual hose air bed pump. The "dual" part matters: two hoses support two separate air chambers, so each side of the bed inflates independently. The included wireless remote sends commands to the pump for both sides, and the pump itself is built in to the air system. The unit is white, made in the United States, and carries the model number SFCS56DR.

The strongest reason to choose this pump is the complete package: pump, wireless remote, power cord, plus a two-year warranty and the seller's trade-in option. For a used component, that extra coverage is meaningful. The main limitation is the condition: this is a used pump, and the seller, Deelz 4 Less, notes it is not an authorized reseller or affiliated with Select Comfort. So you're getting a third-party used part with its own warranty, not a brand-new factory-direct unit.
Meaningful trade-offs
Used condition is the biggest trade-off. You don't get the "new in box" experience, and the seller makes clear it's not an authorized Sleep Number reseller. That said, the listing addresses that concern by offering two years of warranty and a trade-in path for your old broken pump and remote. If you prefer never to buy used electronics, that might push you away. But if the price and the included remote match what you need, the used status is a reasonable compromise for a replacement part.
Another trade-off is the fit: this is built for dual-chamber queen and king systems, so the two-hose design pairs with mattresses that have separate left and right chambers. Match that setup before ordering.
Bottom line
The Sleep Number SFCS56DR is a focused replacement pump for a specific problem. It includes the essentials, covers you with a two-year warranty, and gives you a trade-in route for the old broken unit. If used-condition parts are okay with you, this is a solid answer to a failing Sleep Number pump. If you need a factory-fresh unit, you'll have to look elsewhere.
