Shopping for sleep comfort parts is less about picking the fanciest item and more about matching the exact role: a cover for a specific base or mattress, hoses for an air-bed setup, or a pump for a queen or king air mattress. The four choices here are not interchangeable, so the best pick depends on which part of the bed system you are trying to replace or adapt.
Quick take
- Best for an Eastern King foundation cover: Sleep Number Select Comfort Eastern King Base Foundation FABRIC COVER ONLY, because it is specifically described as an E-King modular base foundation cover.
- Best for a Twin XL C2 mattress bottom cover: Sleep Number Select Comfort C2 Twin XL Mattress BOTTOM COVER ONLY Bed Zipper, because the title and details focus on the bottom cover role.
- Best for hose extension needs: 2 Extension Hoses Compatible with Select Comfort Sleep Number Air Bed Pump, because it includes a pair of hoses with connector details.
- Best for replacing a pump assembly in this group: Select Comfort Sleep Number Air Bed Pump For Queen King Mattress Model PFCS03-DR, because it includes the pump, remote, hoses, and power cord described for that model.
Listed price comparison
The price range runs from $38 to $223.24, with the lowest listed price about 83% below the highest. That spread makes sense because the group mixes fabric covers, hoses, and a pump assembly rather than four versions of the same part.

Concise product notes
Sleep Number Select Comfort Eastern King Base Foundation FABRIC COVER ONLY
This is the most direct choice if the missing or worn part is the fabric cover for a Sleep Number E-King modular base foundation. The stated 76 x 80 measurement and King size positioning make it the clearest match for that specific base-cover need, and the gray fabric material keeps the role straightforward. The limitation is right in the title: it is fabric cover only, so it should not be treated as a foundation, mattress, pump, or structural replacement. It is also listed as used, with a couple of marks noted on the underside, so it is best for shoppers focused on replacing the cover rather than buying a new-looking full bed component.
Sleep Number Select Comfort C2 Twin XL Mattress BOTTOM COVER ONLY Bed Zipper
This option is aimed at a narrower mattress-cover repair: the bottom cover for a Sleep Number Select Comfort C2 Twin XL mattress with a bed zipper. It makes sense when the rest of the mattress setup is already in place and the needed piece is specifically the lower cover section. The gray color and Sleep Number C2 Twin XL Adjustable model reference help separate it from the Eastern King foundation cover above. Its limitation is that it is also a bottom cover only item, not a full mattress, top cover, air chamber, or pump. It is listed as used, though the description says good condition and no stains.
2 Extension Hoses Compatible with Select Comfort Sleep Number Air Bed Pump
The D4L hose pair is the practical pick when the issue is reach or connection between compatible Select Comfort Sleep Number air bed pump parts and air chambers. Each hose is described as 5 feet long, and the set includes a female connector on one end and a male connector on the other. It is also the only new item in this group, which may matter if you are choosing between used covers and a new accessory part. The tradeoff is that this is only a hose-extension set. It does not include a pump, remote, air chamber, bladder, mattress cover, or foundation cover, so it solves a connection need rather than a complete air-bed control problem.
Select Comfort Sleep Number Air Bed Pump For Queen King Mattress Model PFCS03-DR
This is the broadest functional component in the group: a Select Comfort Sleep Number air bed pump for queen and king mattress setups, model PFCS03-DR. It is described with two hoses, one wireless remote, and a power cord, with the remote operating left and right sides. That makes it the natural option when the target part is the pump assembly rather than a cover or hose extension. The important limitation is the remote condition: it is described as showing no display numbers and having no battery cover, even though it can still be used to inflate and deflate by feel. It is also listed as used, so shoppers wanting a cover-only repair would be overspending here.
Final recommendation
If your sleep comfort project is a cover replacement, choose based on the exact bed section first, not the lowest price alone. The Sleep Number Select Comfort Eastern King Base Foundation FABRIC COVER ONLY is the lowest listed option at USD 38.00 and is the right fit here only when the needed part is the E-King modular base foundation fabric cover. For a Twin XL C2 mattress lower section, the Sleep Number Select Comfort C2 Twin XL Mattress BOTTOM COVER ONLY Bed Zipper is the more targeted choice at USD 94.99.
If the problem involves air movement rather than fabric, the decision changes. The 2 Extension Hoses Compatible with Select Comfort Sleep Number Air Bed Pump at USD 52.24 is the sensible pick for adding a pair of 5-foot hose extensions with male and female connector ends. For a pump-centered replacement, the Select Comfort Sleep Number Air Bed Pump For Queen King Mattress Model PFCS03-DR is the relevant option at USD 223.24, especially because it includes the pump, two hoses, wireless remote, and power cord; just account for the remote condition described above.
Overall, the best buy is the one that matches the failed or missing component. Pick the Eastern King foundation cover for a base-cover need, the C2 Twin XL bottom cover for that mattress-cover section, the D4L hose pair for extension connections, and the PFCS03-DR pump when the pump assembly is the part you are replacing.
