Choosing for sleep comfort gets tricky when the options are not all the same kind of product. Here, the decision is less about picking one universal "best" item and more about matching the item to the job: a complete RV mattress, an inflatable queen airbed, a Sleep Number air pump, or a fabric cover for an Eastern King base foundation.
Quick take
- Best for a full RV sleep surface: Short King RV Mattress 10" Green Tea Memory Foam for Cool Sleep & Comfort 72"x75. It is the only complete foam mattress in the group and is sized for a short king RV setup.
- Best for an inflatable guest or temporary bed: Queen Size Air Mattress 22" Inflatable Blow Up Mattress Airbed w/ Built-in Pump. It combines an inflatable queen format with a built-in pump and foldable design.
- Best for a Sleep Number air-system replacement part: Select Comfort Sleep Number Air Bed Pump For Queen King Mattress Model NXT03DR. It is a used pump with two hoses, a wireless remote, and Queen/King wording in the title.
- Best for a fabric-only base refresh: Sleep Number Select Comfort Eastern King Base Foundation FABRIC COVER ONLY. The title is very specific: this is a cover only, not a mattress, pump, or full foundation.
The listed range runs from $38.00 to $532.99, with the lowest price about 93% below the highest. That spread makes the intended use especially important: a low-cost cover and a full RV mattress are not solving the same sleep comfort problem.

Decision matrix
Choose the queen air mattress if you want a new inflatable sleep surface with built-in inflation. Its attributes include Built-in Pump, Electric Pump, Foldable, Inflatable, Outdoor Use, Pump Included, and Waterproof, so it is the most portable-style sleep surface here.
Choose the short king RV mattress if you need a complete 72"x75" mattress for an RV-sized bed space. The title calls out green tea memory foam, cool sleep, comfort, and a 10" profile, and the description describes a medium feel rated around 5 out of 10.
Choose the Sleep Number air bed pump if the main issue is the air-control component for a compatible Queen or King air bed setup. The model is NXT03DR, and the description says it includes one air pump, one wireless remote, and a power cord.
Choose the Eastern King foundation cover if the base foundation fabric is the part you are replacing. The title and type make the scope narrow: fabric cover only, for a Sleep Number E-King foundation modular setup.
Concise product notes
Queen Size Air Mattress 22" Inflatable Blow Up Mattress Airbed w/ Built-in Pump
This JHK airbed is the most straightforward pick when the goal is a standalone inflatable bed rather than a component. The 22" height, queen size wording, built-in 110V electric pump, flocking top, non-slip bottom, and listed 660 lb maximum load capacity all point toward temporary sleep comfort with easier setup than a separate-pump air mattress. Its new condition also separates it from the two used Sleep Number parts. The limitation is that it is still an inflatable PVC and flocking airbed, not a permanent foam mattress or a replacement part for a Sleep Number system.
Short King RV Mattress 10" Green Tea Memory Foam for Cool Sleep & Comfort 72"x75
This is the only option here that reads as a full mattress for an RV bed: short king sizing, 10" thickness, green tea memory foam, and 72"x75" dimensions are all in the title. The description's medium feel language, around 5 out of 10 on the firmness scale, makes it a better fit for shoppers who want cushioning with contouring rather than an air-based setup. It also includes gel-infused foam and a fiberglass-free FR inner cover in the description. The tradeoff is that it is the highest listed price in this comparison, so it is not comparable to a cover-only or pump-only purchase.
Select Comfort Sleep Number Air Bed Pump For Queen King Mattress Model NXT03DR
This used Sleep Number pump is the targeted choice for someone shopping around the air-control side of a Queen or King air bed. The model number NXT03DR, two-hose design, wireless remote, and power cord are the most important clues: it is meant as a pump component, not as a full mattress. Its attributes also call out adjustable firmness, dual chamber, multiple chamber, pump included, and firmness control system language. The limitation is the same specificity that makes it useful: it is a used component, and it will not help someone who needs a complete sleeping surface or a base cover.
Sleep Number Select Comfort Eastern King Base Foundation FABRIC COVER ONLY
This Sleep Number fabric cover is the narrowest and lowest-cost item in the group. It is gray fabric, used, King size, and identified as a Sleep Number E-King Foundation Modular cover with the product line including E King - C2/C3/C4/P5/DP5/i8/CSE/F04. The description says it measures 76" x 80" and is free of rips, with a couple of marks on the underside. The main limitation is built directly into the title: FABRIC COVER ONLY. It is not a mattress, not a foundation, and not an air pump.
How to choose by use case
For a guest room, camping-style setup, or temporary sleeping arrangement, the queen inflatable airbed is the easiest match because it is the only product combining an air mattress format with a built-in pump. The foldable and inflatable attributes also make it more flexible than a fixed foam mattress.
For an RV bed, the short king memory foam mattress is the clearest fit because the size is explicit and the product is a complete mattress. The 72"x75" wording matters: it is not the same purchase as a standard household king accessory or an air pump.
For an existing Sleep Number-style air bed, the pump and fabric cover serve different repair or refresh needs. The NXT03DR pump is about air control and dual hoses. The Eastern King fabric cover is about covering a modular base foundation. Mixing those up would leave you with the wrong part even if the brand wording looks familiar.
Final recommendation
If you need a complete sleep surface for an RV, pick the Short King RV Mattress 10" Green Tea Memory Foam for Cool Sleep & Comfort 72"x75 despite its top-end placement in the listed price spread, because it is the only full short king RV mattress here. If you want a lower-priced standalone bed for temporary sleep comfort, the Queen Size Air Mattress 22" Inflatable Blow Up Mattress Airbed w/ Built-in Pump is the better match because it is new, inflatable, and includes the pump in the design.
For parts, do not treat the Sleep Number items as interchangeable. Choose the Select Comfort Sleep Number Air Bed Pump For Queen King Mattress Model NXT03DR only when the pump, remote, and dual-hose air system are the target. Choose the Sleep Number Select Comfort Eastern King Base Foundation FABRIC COVER ONLY only when the needed item is the 76" x 80" E-King modular foundation cover.
