Truck mattress sizes for semi-truck sleeper berths and pickup truck beds, the best materials for road use, how thick to go and how to keep the mattress from sliding.
Stearns & Foster Studio MediumStyled product scene
"Truck mattress" means two different things depending on who is searching. For long-haul drivers, it is the mattress in a semi-truck sleeper berth, where you may spend more nights than in your own bed at home. For campers and weekend adventurers, it is a mattress that fits the bed of a pickup truck. Both need to fit an awkward space, stay put, and still let you wake up rested. This guide covers both.
Sleeper berths vary by manufacturer, model, year and cab configuration, but most fall within a common range. Treat the table below as a starting point, not a guarantee.
| Width | Length | Where you typically see it |
|---|---|---|
| About 35 inches | About 79 to 80 inches | Narrow berths and some older sleepers |
| About 38 inches | About 79 to 80 inches | One of the most common single-berth widths |
| About 42 inches | About 79 to 80 inches | Wider single berths in many mid-roof and raised-roof sleepers |
| About 48 inches or more | About 80 inches | Larger sleepers and upgraded bunk configurations |
Measure before you buy. Measure width and length at the platform, then check for angled corners, curved walls, storage lids and anything that intrudes into the bunk. Measure the headroom from the platform to the ceiling or upper bunk as well, because it limits how thick the mattress can be.
A standard twin mattress (about 38 by 75 inches) matches the width of many berths but is usually about five inches too short. That gap lets the mattress slide and leaves your feet hanging off a hard edge, which is why a berth-specific size is worth the effort.
Pickup beds come in several lengths, and the space between the wheel wells is the number that decides what fits flat on the floor. Rough guidance for common beds:
| Bed type | Approximate floor length | What usually fits |
|---|---|---|
| Short bed (about 5.5 ft) | About 66 inches | A twin or full laid on top of the wheel wells with the tailgate down, or a shorter custom foam pad |
| Standard bed (about 6.5 ft) | About 78 inches | A twin between the wheel wells in many full-size pickups, or a full on top of the wheel wells |
| Long bed (about 8 ft) | About 96 inches | A full-length twin or full with room to spare; a queen on top of the wheel wells in wider trucks |
| Midsize pickups | About 5 to 6 ft | Narrower between the wheel wells, so a twin-width pad or a trimmed foam mattress is typical |
Always measure your own truck: bed width, the gap between the wheel wells and the length with the tailgate closed and open. If you prefer inflatable, our guide to setting up a truck bed air mattress covers pumps, sizing and insulation from the cold truck floor.
| Material | Feel | Pros | Cons |
|---|---|---|---|
| Memory foam | Contouring, pressure relieving | Quiet, no springs to wear from road vibration, eases pressure after long hours sitting | Can sleep warm; heavier |
| Gel or cooling memory foam | Contouring with better heat dissipation | Helps in a closed cab or a hot truck bed | Slightly higher cost |
| High-density support foam | Firm and even | Durable, affordable, holds shape, easy to trim | Less pressure relief on its own |
| Latex | Responsive and buoyant | Very durable, breathable, resists sagging | Heavy and more expensive |
| Innerspring | Bouncy, traditional | Good airflow | Springs suffer from constant vibration, hard to cut to shape, heavy |
| Air mattress | Adjustable firmness | Packs down small for occasional camping | Punctures, slow leaks and a cold sleeping surface |
Best overall: a foam mattress with a supportive high-density base and a memory foam or latex comfort layer. Foam handles vibration, fits without a frame, and can be trimmed for odd shapes. For occasional truck bed camping, a thick foam topper over a firm pad is a lighter, cheaper alternative, and our mattress toppers are a good place to start.
Foam reaches full support with less height than springs, so in a low-clearance berth a 6-inch memory foam mattress usually feels better than a 6-inch innerspring. Leave a few inches above the mattress for bedding and to sit up.
Angled corners, wheel wells and sleeper cabinets often mean a standard size will not fit cleanly. Foam can be cut to almost any shape, which is why it dominates the custom truck and RV market. Our guide to RV mattress sizes covers many of the same short and narrow sizes. If you have measurements and are not sure what will work, contact our team and we will talk you through the options.
Most semi-truck sleeper mattresses are roughly 35 to 42 inches wide and 79 to 80 inches long, with 38 and 42 inches among the most common widths. Larger sleepers may take 48 inches or more. Measure your own berth, because sizes vary by make, model and year.
In many full-size pickups with a standard bed, a twin fits between the wheel wells and a full fits on top of them. Short beds usually need the tailgate down for a full-length mattress, and midsize trucks often need a twin-width or trimmed pad. Measure the floor length and the space between the wheel wells first.
A queen is about 60 by 80 inches, wider than the space between most wheel wells, so it will not lie flat on the floor. In a wide full-size pickup with a long bed, or with the tailgate down, a queen can rest on top of the wheel wells. For most trucks a twin or full is the practical choice.
Sometimes, but rarely well. A standard twin is close in width to many berths but usually several inches too short, so it slides and leaves a gap. A mattress sized for the berth is more comfortable and safer.
A quality foam truck mattress typically lasts around five to eight years of regular use. Denser support foam holds up better against nightly use and road vibration than budget foam. Replace it when you see permanent dips or wake up sore.
Whether you run long hauls or camp from your tailgate, the right foam and the right fit make the difference. Browse our memory foam mattresses for materials that travel well, or stop by any of our five Los Angeles showrooms to feel foam densities side by side before you commit.
Start with a mattress type that suits how you sleep, then compare the feel in person.
