Air Mattress for Truck Bed | Fit Guide That Works

Truck-bed air mattresses use wheel-well cutouts and DC pumps to turn pickup beds into camp-ready sleeping space.

Camping in a pickup bed beats a tent on wet ground, but only if the sleeping surface fits. A standard rectangular air mattress won’t sit right in a truck bed because it has to bridge the wheel wells, which wastes space and shifts overnight. An air mattress for truck bed solves that with molded cutouts and a pump that runs off the truck’s own power. Pittman Outdoors, which markets AirBedz as “The Original Truck Bed Air Mattress,” built the category around this exact problem.

The fit comes down to two numbers: bed length and the width between the wheel wells. Get those right and the mattress sits flat, inflates fully, and stays put. Get them wrong and you’re sleeping on a slope.

How To Measure Your Truck Bed For An Air Mattress

Measure before you shop, not after. You need three numbers, and the wheel-well width is the one that actually determines compatibility.

• Length: from the cab wall to the inside of the tailgate, in the bed’s center.
• Width: sidewall to sidewall across the bed’s widest point.
• Wheel-well width: the distance between the two humps. This is the number manufacturers design around.

Match the wheel-well width first. An AirBedz Original model lists its built-in pump and “Fits Around Truck Bed Wheel Wells” right in the product name, and its dimensions for a Full Size Short model come in at 76 in long by 63.5 in wide by 12 in tall — that height matters, because the mattress sits over the humps. A long-bed version stretches to 95 inches. Luno’s AIR Truck Bed Mattress page sorts its compatibility by bed-size category, including “Mid-Size 5ft Bed,” which confirms that a mattress sized for one truck class won’t automatically work in another.

A mattress built for a “6 to 6.5 ft” bed won’t fit a 5.5-foot or mid-size bed, so verify the exact bed length in feet before ordering. Truck beds vary by make and model even within the same nominal length class.

Pump And Power: What Each Type Means For You

Air mattresses for truck beds use one of two power setups, and the difference affects where you can sleep. Many models plug into the truck’s DC cigarette-lighter power port. That’s fine when you camp near the cab, but it tethers the mattress to the vehicle and drains the battery if the truck isn’t running.

Some models, including certain Pittman AirBedz versions, use built-in rechargeable pumps that remove that dependency entirely. You inflate the mattress without touching the truck’s electrical system, which means you can set up camp, detach, and drive away without leaving the mattress wedged against the cab. The trade-off is that a rechargeable pump needs to be charged before you leave, and if it dies mid-camping-trip, you’re back to a manual pump or no inflation at all.

Check the pump type on the specific listing before buying. “12-Volts Pump” on a spec sheet means the cigarette-lighter port; “Built-In Rechargeable” means a self-contained battery pack.

What To Look For Before You Buy

The defining feature of a truck-bed air mattress is the wheel-well cutout, and it’s non-negotiable for a proper fit. Standard rectangular mattresses waste space and slide around over the humps, which ruins both comfort and insulation. Beyond the cutouts, run through these checks:

• Bed-length match: confirm short bed, long bed, or exact feet measurement.
• Pump type: DC port or rechargeable battery — know which one you’re getting.
• Material and height: taller profiles (like the 12-inch AirBedz) sit more comfortably but take longer to inflate.
• Extras: two pillows and a storage bag are common inclusions and cut what you pack.
• Warranty: some models carry a 1-year manufacturer warranty.

Prices vary widely by brand and construction — expect anywhere from roughly $67 for a basic model to over $500 for premium builds. Product availability and pricing shift with seller and marketplace, so compare current listings rather than assuming a single price holds.

FAQs

Will a regular air mattress work in a truck bed?

A regular rectangular mattress will inflate and cover the bed, but it sits awkwardly over the wheel wells, wastes usable width, and tends to shift during the night. A truck-bed-specific mattress with wheel-well cutouts sits flat and stays put, which is why the dedicated design exists.

How do I know what size truck bed air mattress to buy?

You need the bed length (cab to tailgate) and the width between the wheel wells. The wheel-well width is the key compatibility number — manufacturers size their cutouts around it. A mattress for a 6 to 6.5 ft bed won’t fit a 5.5 ft or mid-size bed, so verify the feet measurement before ordering.

Can I inflate a truck bed air mattress without the truck running?

Only if the mattress has a built-in rechargeable pump. Models that plug into the DC cigarette-lighter port need vehicle power to inflate, which means the truck must be on or at least have battery power available. Rechargeable models inflate anywhere but need to be charged ahead of time.
