When a sleep-comfort setup needs a replacement piece, the hard part is separating a chamber, bladder, cover, and control component before comparing prices. These four listings cover distinctly different jobs, from a right-side Eastern King air chamber to a C2 Twin XL bottom cover. The clearest route is to match the component wording first, then weigh condition and the listed price.
Quick take
Start with the component type rather than the price. The Sleep Number Select Comfort Air Chamber King S 274 E-KING Bed RIGHT Side Zipper is the dedicated Eastern King chamber choice, while the Sleep Number Select Comfort E-King Bladder S-274 E-King 118886 R Zippered is a zippered 1/2 King bladder. The Sleep Number Select Comfort C2 Twin XL Mattress BOTTOM COVER ONLY Bed Zipper is specifically a cover-only option. The Sleep Number Bed Select Comfort Air Pump/Control Module is the outlier: it is a pump and control-module set, listed in for-parts-or-not-working condition.
Listed price comparison
The listed range runs from USD 80.00 to USD 150.00, a USD 70.00 spread. Price alone does not make these interchangeable because each listing names a different part category.
| Component | Listed price | Relative price |
|---|---|---|
| Sleep Number Select Comfort Air Chamber King S 274 E-KING Bed RIGHT Side Zipper | USD 150.00 | |
| Sleep Number Bed Select Comfort Air Pump/Control Module | USD 80.00 | |
| Sleep Number Select Comfort C2 Twin XL Mattress BOTTOM COVER ONLY Bed Zipper | USD 94.99 | |
| Sleep Number Select Comfort E-King Bladder S-274 E-King 118886 R Zippered | USD 100.00 |
Decision matrix
- Eastern King chamber focus: The S-274 right-side chamber is the listing to prioritize when that wording matches the part being sought. Its used condition and minor discoloration are part of the trade-off.
- Zippered bladder focus: The S-274 E-King 118886 R listing is aimed at a 1/2 King bladder need. Stains are noted in its description.
- C2 cover-only need: Choose the C2 Twin XL entry when the needed piece is specifically the mattress bottom cover, not an air chamber.
- Pump and control-component need: The FlexFit 2/3K module listing includes an air hose, but the nonworking remote and absent power cables make its condition details central to the decision.
Product notes
Sleep Number Select Comfort Air Chamber King S 274 E-KING Bed RIGHT Side Zipper
This used Select Comfort air chamber is the most focused choice for an S-274 Eastern King, right-side configuration with a zipper. Its description identifies an inflated bladder size of 72 by 34 by 6 inches and calls the chamber fully functional, making it the clearest fit in this group for a shopper seeking that specific chamber format. The limitation is cosmetic condition: minor discoloration may be present. It is also the highest-priced listing here at USD 150.00, so its appeal rests on needing the right-side Eastern King chamber designation rather than simply choosing the lowest listed price.
Sleep Number Bed Select Comfort Air Pump/Control Module
The air pump and control-module set suits a component-focused need rather than a fabric cover or inflatable chamber. It names air pump model 360SIQ010 and FlexFit 2/3K control module, and an air hose is included. At USD 80.00, it has the lowest listed price in the comparison. The key limitation is substantial: the condition is marked for parts or not working, the remote is not working, and power cables are not included. The description says the unit was controlled with the Sleep Number app, but the stated condition remains the deciding consideration.
Sleep Number Select Comfort C2 Twin XL Mattress BOTTOM COVER ONLY Bed Zipper
For a C2 Twin XL sleep-comfort setup needing the lower fabric piece, this gray Sleep Number option is clearly labeled Bottom Cover Only. That direct wording is its strongest reason to choose it: it narrows the role to the mattress bottom cover with a zipper rather than suggesting a full mattress component. The description calls the used cover in good condition with no stains. Its limitation is equally direct: it is only the bottom cover, so it does not serve the same purpose as either S-274 air chamber or the pump/control module. The listed price is USD 94.99.
Sleep Number Select Comfort E-King Bladder S-274 E-King 118886 R Zippered
This used beige Sleep Number bladder is the dedicated choice for the S-274 E-King 118886 R, zippered 1/2 King format. The description reports that the bladder held air for 72 hours, giving the listing a specific functional detail beyond its model wording. Its USD 100.00 price places it between the cover-only entry and the right-side Eastern King chamber. The limitation is condition: stains are called out in the description. Choose this entry for the named zippered bladder use case, not as a substitute for the C2 cover or the separate pump/control-module assembly.
Final recommendations by use case
Choose the Sleep Number Select Comfort Air Chamber King S 274 E-KING Bed RIGHT Side Zipper when the target is a right-side Eastern King S-274 chamber. Pick the Sleep Number Select Comfort E-King Bladder S-274 E-King 118886 R Zippered for the named 1/2 King bladder format. The Sleep Number Select Comfort C2 Twin XL Mattress BOTTOM COVER ONLY Bed Zipper is the direct choice for a C2 Twin XL bottom-cover need. Reserve the Sleep Number Bed Select Comfort Air Pump/Control Module for a pump and module project where its listed condition and included air hose suit the task.
