King Koil lists a flocked top and sides, internal coil-beam construction and a built-in electric pump. The advertised pump specification is 120V/210W; this makes access to compatible mains power an important buying consideration. These are manufacturer specifications, not our own test results.

It is worth researching if you want a temporary indoor guest bed with an integrated pump and a choice of raised heights. Before ordering, measure the room, confirm the exact size-and-height combination, and check access to a compatible electrical outlet. If you need a mattress for off-grid camping, investigate power compatibility before buying.
Sizes and raised heights
King Koil lists twin, full, queen and California king variants, with 13-, 16- and 20-inch heights, plus a separate kids' option. The dimensions below are the manufacturer's listed measurements; confirm the selected variant at checkout. Manufacturer specifications
| Size | Listed length × width | Listed height choices |
|---|---|---|
| Twin | 76 × 40 in (20-inch variant: 76 × 42 in) | 13, 16, 20 in |
| Full | 75 × 54 in | 13, 16, 20 in |
| Queen | 80 × 60 in | 13, 16, 20 in |
| California king | 84 × 72 in | 13, 16, 20 in |
| Kids | 66 × 44 in | 13 in |
Choose based on actual floor space, access around the mattress and how easily your guest can get onto a lower or higher sleeping surface. A higher profile does not itself prove greater comfort.
What do independent testers report?
Good Housekeeping's August 2026 roundup reports testing 15 air mattresses and names the King Koil Luxury Raised Air Mattress its built-in-pump selection. The same roundup names SoundAsleep Dream Series its overall selection and Intex Dura-Beam Deluxe Comfort its value selection. Those are Good Housekeeping's findings, not tests conducted by this publication. Read the original testing article
What should you verify before checkout?
- Power: the listed built-in pump is 120V/210W; verify compatibility with your intended location.
- Dimensions: check the selected variant rather than assuming every twin has the same width.

- Warranty: the published limited warranty covers specified manufacturing defects for one year, with exclusions. Read full policy
Questions shoppers ask
Does it have a built-in pump?
Yes, the manufacturer's Luxury Air Mattress product listing describes a built-in electric pump. Check the exact variant and electrical requirements before ordering.
Is the queen model the right size?
The manufacturer lists queen dimensions of 80 × 60 inches. Measure the available floor area and leave room to move around the bed.
Have we slept on it?
No. This guide uses published product information and attributed independent testing, not firsthand use.

Check King Koil at the merchant ↗How to evaluate the exact King Koil variant
Start by selecting the intended size and height on the merchant page. Product-family descriptions can combine details from several variants; check the selected variant's inflated dimensions, power specification, capacity and included accessories individually. Compare the footprint with your room and confirm that a compatible outlet is within safe reach.
The manufacturer’s published details are useful for narrowing the choice, but they are not a substitute for independent long-term durability data. We have not inflated, slept on or measured the mattress ourselves. Treat any reported third-party test as evidence about the model tested, not proof that every King Koil version performs identically.
Questions to resolve before ordering
- Does the chosen height work for the guest's preferred entry and exit height?
- Can the inflated bed fit while preserving access to doors and furniture?
- Is the pump compatible with the available mains supply?
- What are the current return conditions for a mattress that has been inflated?
- Which warranty exclusions and proof-of-purchase requirements apply?
For a reusable approach, consult our buying checklist. If you are still comparing brands, read the King Koil, SoundAsleep and Intex comparison before choosing.
Who may want a different type of bed
A person who needs an off-grid sleep system should investigate a mattress and pump designed for that power situation. A frequent, long-term sleeper should compare the manufacturer's intended-use guidance with a conventional bed rather than assuming an inflatable guest mattress is a permanent substitute. For cold-ground camping, investigate documented insulation performance; thickness alone does not establish it.
A final decision should rest on the selected model's specifications, current seller terms and the sleeper's needs—not on a blanket claim that one brand is right for everyone.
