Replacing part of an adjustable air bed is a different sleep comfort decision from replacing the whole bed. The key choice here is whether you need the air chamber that holds the air or the control hardware that inflates two chambers separately. The Select Comfort Sleep Number Air Bed Chamber Twin Size Mattress S 276 TWIN XL A and the Select Comfort Sleep Number Air Bed Pump for Dual Chamber Queen King Mattress serve those distinct roles.
Quick verdict
Choose the twin-size air chamber when your priority is a single air chamber with one port. Choose the dual-chamber pump when your setup calls for two hoses, a wireless remote, and separate left-and-right operation. Both are used Sleep Number items with adjustable-firmness and inflatable features, but they are not substitutes for the same replacement need.

Where each one wins
The Select Comfort Sleep Number Air Bed Chamber Twin Size Mattress S 276 TWIN XL A wins for chamber replacement. Its one-port layout is paired with two O-rings, and the description gives dimensions of 30 by 72 by 6 inches. It is the more direct choice when the air-holding chamber is the part being replaced rather than the pump and remote system.
The Select Comfort Sleep Number Air Bed Pump for Dual Chamber Queen King Mattress wins for dual-side control. Model SFCS56DR is described with a dual-hose pump, wireless remote, and power cord. The remote operates the left and right sides, making this the relevant pick for a dual-chamber setup where inflation and firmness adjustment hardware are the priority.
Product notes
Select Comfort Sleep Number Air Bed Chamber Twin Size Mattress S 276 TWIN XL A
This chamber makes sense for a shopper focused on the air bladder portion of a twin-size adjustable air bed. The listed one-port arrangement and two O-rings make its connection design the central detail, while the 30 by 72 by 6 inch dimensions add useful context for the chamber itself. Its listed price places it at the lower end of this comparison. The limitation is equally important: this is an air bed chamber, not a pump-and-remote control kit. A shopper whose problem is dual-side inflation, wireless adjustment, or pump operation should look instead at the SFCS56DR pump package.
Select Comfort Sleep Number Air Bed Pump for Dual Chamber Queen King Mattress
The SFCS56DR is the stronger fit when the needed component is the system that manages two air chambers. Its two hoses are assigned one per chamber, and the included wireless remote is described as operating the left and right sides. Receiving an air pump, wireless remote, and power cord keeps the focus on replacing the firmness-control hardware together. The tradeoff is its higher listed price in this two-item comparison. It is also identified for a dual-chamber Queen King mattress, so it is less targeted for someone shopping specifically for the twin-size air chamber named above.
Final choice by use case
Pick the Select Comfort Sleep Number Air Bed Chamber Twin Size Mattress S 276 TWIN XL A for a single twin-size chamber need and a one-port configuration. Pick the Select Comfort Sleep Number Air Bed Pump for Dual Chamber Queen King Mattress when two-chamber pumping and left-right wireless control are the reason for replacing a part. The listed price spread is USD 211.54, so the choice comes down to whether you need the chamber itself or the dual-chamber control system.
