Quick Answer: The AirBedz Original (about $309.99 full-size, $319.99 mid-size, direct from Pittman Outdoors) is the best truck bed air mattress overall — its wheel-well cutouts use the full bed width at 12 inches thick, with a built-in rechargeable pump and a 1,200-lb capacity. For trucks whose wheel wells don’t match a cutout design, or anyone who also wants to use the mattress outside the truck, the flat AirBedz Lite (about $179.99) skips the cutouts for universal fit. Budget-focused buyers do well with the Rightline Gear Full-Size (about $99.95) or Mid-Size (about $89.95) — both 7 inches thick with a 12V pump and side storage pockets where the wheel wells sit. The fitment question matters more than price here: a cutout mattress in the wrong bed simply won’t lie flat.
Sleeping in the bed instead of pitching a ground tent sounds like it solves the hard-ground problem on its own, but a stock steel bed floor is no softer than dirt — you still need something to sleep on. “Truck bed air mattress” isn’t one product, though: some are cut to wrap around the wheel-well humps and use the full bed width, and some sit flat on top of them, trading a few inches of width for fitting almost any bed. Below are the best truck bed air mattresses of 2026, with that fitment difference called out up front so you don’t order the wrong shape.
Truck bed air mattresses by the numbers
- The AirBedz Original is rated to a 1,200-lb weight capacity, per Pittman Outdoors’ own spec sheet — enough for two adults plus gear, well beyond what the mattress itself needs to support for sleeping.
- AirBedz and AirBedz Lite both inflate to 12 inches thick, versus 7 inches for the Rightline Gear mattresses — nearly double the cushioning, at the cost of more headroom lost under a cap or tent roofline.
- A full-size short truck bed (5.5–5.8 ft) is the most common fitment, per Pittman Outdoors’ size chart, which is why most brands sell a dedicated full-size-short SKU alongside mid-size and long-bed variants — measuring your actual bed length before ordering avoids the single most common return reason.
- Both AirBedz and Rightline Gear ship a patch kit in the box — an acknowledgment from both brands that a slow leak is a when-not-if reality of sleeping on air, not an if-it-breaks edge case.

1. AirBedz Original — Best Overall
AirBedz Original Truck Bed Air Mattress
- Wheel-well cutouts let the mattress wrap around the bed's humps and use the full width for sleeping, instead of sitting narrower on top of them.
- Built-in rechargeable NiMH battery pump inflates and deflates without hunting for an outlet or running the truck — a real convenience advantage over DC-only pumps.
- 1,200-lb weight capacity and RF-welded (not glued) seams for durability over repeated trips.
- Only fits beds whose wheel-well spacing matches the cutout — check Pittman Outdoors' fitment chart for your specific truck and bed length before ordering.

The AirBedz Original earns the overall pick because it’s the only mattress here that actually uses the entire bed floor — the cutout design means you’re not losing width to the wheel-well humps the way every flat mattress does. At 12 inches thick with a 1,200-lb capacity and a rechargeable pump, it’s built for someone who sleeps in the bed regularly, not just on the occasional trip. The tradeoff is fitment: this only works if your bed’s wheel wells land where the cutouts expect them, so confirm the chart before buying rather than assuming “truck bed” means universal fit.
2. AirBedz Lite — Best Universal Fit
AirBedz Lite Truck Bed Air Mattress
- Flat-bottom design sits on top of the wheel wells instead of cutting around them, which means it fits a far wider range of truck beds, SUVs, and truck bed tents.
- Same 12-inch inflated thickness as the Original, so comfort doesn't drop even though the cutout feature does.
- Portable DC air pump plugs into a 12V outlet rather than the Original's built-in rechargeable battery pump — one more cable to manage, but a lower price for it.
- Loses a few inches of usable bed width where the wheel-well humps sit underneath, since nothing is cut away to clear them.
The Lite is the right call when you’re not sure your bed matches a cutout mattress’s fitment chart, or when you want one mattress that also works in an SUV, on the ground in a truck bed tent, or loaned out for a friend’s different truck. You give up the Original’s full-width sleeping area and its rechargeable pump, but at roughly $130 less, it’s the lower-risk pick for a first truck bed air mattress — and it’s still the same 12-inch thickness, so comfort isn’t the thing you’re trading away.
3. Rightline Gear Full-Size — Best Value
Rightline Gear Full-Size Truck Bed Air Mattress (110M10)
- 80 in L x 51 in W x 7 in H, fitting full-size short (5.5 ft), standard (6.5 ft), and long (8 ft) beds.
- Sized to fit between the wheel wells with room left over on each side for small gear — phone, keys, headlamp — instead of a dedicated cutout.
- Includes a 12V air pump, patch kit, stuff sack, and setup guide in the box.
- 7-inch inflated height is noticeably firmer against the bed floor than the 12-inch AirBedz models, and leaves more headroom under a cap or bed tent roofline in exchange.
At under $100, the Rightline Gear Full-Size is the mattress most people should start with if they’re not sure how often they’ll actually sleep in the bed. It covers all three common full-size bed lengths with one SKU, ships everything needed in the box, and the lower 7-inch profile is a real advantage under a tight cap or a truck bed tent roofline — just expect a firmer night than the thicker AirBedz options.
4. Rightline Gear Mid-Size — Best for Mid-Size Trucks
Rightline Gear Mid-Size Truck Bed Air Mattress (110M60)
- 76 in L x 44 in W x 7 in H, built for mid-size short (5 ft) and standard (6 ft) beds — Tacoma, Ranger, Colorado, Frontier.
- Same 12V pump, patch kit, and side-storage layout as the full-size version, just scaled to a narrower bed.
- A dedicated mid-size SKU avoids the sag and wasted space of forcing a full-size mattress into a smaller bed.
- Same 7-inch firmness tradeoff as the full-size model versus the 12-inch AirBedz mattresses.
Mid-size truck owners shouldn’t default to a full-size mattress just because it’s the more commonly stocked option — a full-size mattress in a Tacoma or Ranger bed either overhangs the tailgate or bunches up against the cab, neither of which makes for a good night. The dedicated mid-size Rightline Gear mattress is sized correctly from the start, at the same $10-cheaper price point and feature set as its full-size sibling.
How to choose a truck bed air mattress
Start by measuring your actual bed length — full-size short (5.5 ft), standard (6.5 ft), long (8 ft), or mid-size (5–6 ft) — since every mattress here is sold in length-specific SKUs and the wrong one either overhangs the tailgate or leaves a gap. Next, decide on fit style: if you sleep in the bed often and want the full width, check your truck against a cutout mattress’s fitment chart (the AirBedz Original); if you’re not sure it’ll match, or you want one mattress that also works in an SUV or truck bed tent, go flat (AirBedz Lite or Rightline Gear). Finally, weigh thickness against headroom — 12 inches (AirBedz) is more comfortable but eats more vertical space under a cap or tent roof, while 7 inches (Rightline Gear) is firmer but leaves more room to sit up. Whichever you pick, a truck bed mat underneath protects both the mattress and the bed liner from the debris that causes most punctures.
The bottom line
A truck bed air mattress solves the hard-floor problem a truck bed tent doesn’t — but only if the fit style matches your bed. The AirBedz Original is the best overall pick for full-width comfort if your wheel wells match its cutout chart; the AirBedz Lite is the safer universal-fit choice at a lower price if you’re not certain, or if you want the mattress to do double duty outside the truck. Budget-conscious full-size and mid-size truck owners get real value from the Rightline Gear mattresses, trading mattress thickness for a firmer, lower-profile sleep and a sub-$100 price.
