Your sleep comfort depends on the pump keeping each side of your Sleep Number bed firm. When the pump starts to fail, you have two very different replacement paths. One is a more complete, higher-priced pump. The other is a basic, lower-priced inflator. Neither is brand new, so the decision also depends on what you're replacing and how much control you want from the next pump. This head-to-head compares the two used options side by side so you can see which one fits your bed and your spending plan.
Quick verdict
The NXT03DR is the more complete replacement. The EFCS-1 is the simpler, lower-priced pump. If you're looking for a full package and are comfortable with a higher price, the NXT03DR is the one to consider. If you just need a working pump and want to spend less, the EFCS-1 is your pick.

Product notes
Select Comfort Sleep Number Air Bed Pump For Queen King Mattress Model NXT03DR
The NXT03DR is a used, beige pump for queen and king mattresses. Its main strength is that it lets you control the left and right sides of a Sleep Number bed separately, which matters for a two-chamber mattress. It comes with a two-year warranty and a trade-in option for a broken pump, so you're not buying completely unprotected. It arrives with the pump, a wireless remote, and the power cord, so it's a complete set. The limitation is the price: at $324.99, it costs far more than the alternative. And it does not include Sleep Number's own services or warranties, which you should keep in mind if that coverage matters to you.
Sleep Number Select Comfort Motor Pump Inflator with Wired Remote, Hose EFCS-1
The EFCS-1 is the basic pump in this pair. It uses a single hose and a wired remote, keeping the setup straightforward. The description says it works well, and it arrives as the pump, remote, and hose. If your bed uses one chamber or you are replacing a similarly basic pump, this is the lower-priced entry point. It's a direct, uncomplicated way to get a Sleep Number Select Comfort pump back up and running without paying for options you may not use. The limitation is also the simplicity: a single hose and wired remote can't offer the expanded control of the NXT03DR, so this works best in a simple setup.
Final choice by use case
Choose the NXT03DR for a more complete, warranty-backed replacement. Choose the EFCS-1 for a straightforward working pump at the low end of the price range.
