King Koil Air Mattresses at a Glance
King Koil's air mattresses are inflatable beds with built-in electric pumps, sold through King Koil Airbeds under the King Koil Mattress Co. name. They're designed for guest rooms, holiday visitors, moving days and camping where you have power. They're not the same as adjustable air beds like Airpedic, which are built to replace a regular mattress.

Sizes and Heights

| Size | Dimensions (Per King Koil) | Notes |
|---|---|---|
| Kids | 66 x 44 in (outer) | Child-size option |
| Twin | 76 x 40–42 in | 40" wide at 13" or 16" height; 42" wide at 20" |
| Full | 75 x 54 in | |
| Queen | 80 x 60 in | 20" height shown |
| California King | 84 x 72 in | Few air mattresses come this large |
Why height matters: a 20-inch "double-high" air mattress sits close to the height of a regular bed, which makes getting in and out much easier, especially for older guests. Lower profiles (13 or 16 inches) are lighter, pack smaller and work better in tents or tight spaces. King Koil mentions a low-profile option for camping or cabin setups.
The Built-In Pump
The main convenience is the built-in pump. Plug it in, turn the dial and the bed inflates; reverse it to deflate for storage. King Koil calls its pump patented and lists inflation times from about one to two minutes for adult sizes. You can adjust firmness by adding or releasing air.
What to keep in mind:
- You need power. Retail listings describe a 120V AC pump, so plan on an outlet or a suitable power source when camping.
- Top off as needed. All air mattresses lose some firmness overnight as the material stretches and the air cools. Topping off before bed helps.
- Pump issues happen. As with any built-in pump, problems are possible. Keep the box and receipt during the guarantee period.
Comfort and Construction
King Koil's site emphasizes adjustable firmness and fast setup. Retail listings for King Koil's luxury models describe features such as internal air coils ("coil-beam construction"), a flocked or quilted top, and water resistance. Air coils help a mattress keep its shape and avoid the "hammock" effect of a simple inflatable.
Weight capacity: retail listings for King Koil's queen luxury air mattress commonly cite a 600-pound capacity. Check the listing for your exact model and size, since capacity varies.
Sheets: a 20-inch air mattress needs deep-pocket fitted sheets. If you add a topper, go deeper still.
How to Get the Best Sleep on an Air Mattress

- Inflate it a few hours early if possible, then top it off before bed. New air mattresses stretch at first.
- Use a mattress pad or topper for extra comfort and insulation.
- Keep the room temperature stable. Cooler air means lower pressure and a softer bed.
- Place it on a smooth, clean floor away from sharp objects.
- Don't overinflate. A slightly softer setting is usually more comfortable and puts less stress on seams.
- Store it clean and dry, loosely folded, at room temperature.
Why Air Mattresses Lose Air (and What to Do)
Waking up on a soft air mattress is the most common complaint about any inflatable bed, King Koil included. It isn't always a leak:
| Cause | What's Happening | What to Do |
|---|---|---|
| Material stretch | New vinyl or PVC stretches during the first few uses | Inflate early, let it stretch, then top it off |
| Temperature drop | Cooler air at night takes up less space | Keep the room temperature steady; top off before bed |
| Valve not sealed | The pump dial or valve isn't fully closed | Check the dial position after inflating |
| Real leak | A puncture or failing seam | Find and patch it, or use the guarantee if it's new |
Finding a leak: inflate the mattress fully, then listen and feel for escaping air around the seams and valve. If you can't find it, wipe soapy water over suspect areas and watch for bubbles. Most air mattresses come with a patch kit, or you can buy a vinyl repair kit. Let the patch cure fully before re-inflating.
If a brand-new mattress won't hold air, don't patch it. Contact King Koil Airbeds within the 90-day guarantee period instead, since a repair may affect your options.
Setting Up a Comfortable Guest Bed
A few small additions make an air mattress feel much more like a real bed:
- A rug or blanket underneath protects the bottom from rough floors and adds insulation.
- A mattress topper adds cushioning and keeps guests from feeling the air chambers. A thin foam or fiber topper works well. See our best mattresses overview for topper options.
- Deep-pocket fitted sheets stay put on a 20-inch mattress.
- Space around the bed, so guests can get in and out from both sides.
- An extension cord rated for the pump, if the outlet isn't close by.
Using a King Koil Air Mattress for Camping

The built-in electric pump is convenient at home but needs a power source outdoors. For car camping at sites with electric hookups, or in a cabin, it works well. In a tent, a lower-profile model is easier to fit and takes less air to inflate. Put a tarp or groundsheet under the mattress, and keep it away from sharp rocks, sticks and tent stakes. Cold nights make air mattresses feel softer and colder, so bring an insulating layer between you and the air.
If you camp in an RV rather than a tent, a real mattress is a better long-term choice. See our best RV mattress guide.
King Koil Air Mattress vs. Adjustable Air Bed
Both use air, but they're built for different jobs:
| King Koil Air Mattress | Airpedic Adjustable Air Bed | |
|---|---|---|
| Purpose | Guests, travel, temporary use | Everyday mattress |
| Construction | Inflatable bed with built-in pump | Air chambers under foam comfort layers, with a cover |
| Adjustment | One firmness for the whole bed | Three zones per side |
| Setup | Minutes | More involved; stays set up |
| Lifespan | Shorter | Built for nightly use over years |
If you want adjustable firmness for nightly sleep, see our Airpedic review and our adjustable firmness mattress guide.
