A semi-truck mattress needs to fit your sleeper bunk, but finding the right replacement isn't always as simple as ordering a standard mattress size. Bunk dimensions vary between truck models and sleeper configurations, and the factory mattress may not offer the comfort or support you prefer.
At Custom Mattress, you can choose a mattress made to the width, length, and thickness your sleeping space requires. Whether you're replacing a worn-out factory mattress or looking for a different feel, the first step is to confirm the dimensions of your bunk.
What Size Mattress Fits a Semi-Truck Sleeper?
There is no single mattress size that fits every semi-truck. Sleeper bunks come in different widths and lengths, and a truck with both upper and lower bunks may require two different mattresses.
Here are some mattress sizes commonly offered for semi-truck sleeping spaces:
|
Mattress Size |
Where It May Be Used |
|
32" × 80" |
Some narrower or upper sleeper bunks |
|
36" × 80" |
Certain compact sleeper platforms |
|
39" × 80" |
Wider single-sleeper bunks |
|
42" × 80" |
Some larger sleeper platforms |
These are examples of available truck mattress sizes, not guaranteed dimensions for a particular make or model. Your bunk may require a different width, length, or thickness.
If your sleeping platform measures 38" × 79", for example, ordering a mattress labeled 39" × 80" could leave you with an awkward fit. A custom-size mattress can be made to fit your bunk’s exact dimensions, so you don’t have to settle for the closest standard size.
How Do You Find the Best Semi-Truck Mattress for Sleeping on the Road?
Freightliner, Kenworth, Peterbilt, Volvo, International, and Mack offer different sleeper-cab configurations. Mattress dimensions may vary by model, model year, bunk position, and the specific sleeper setup installed in the truck.
A Freightliner Cascadia, for example, may have a different sleeping arrangement from a Kenworth T680 or Volvo VNL. Even within one model family, the lower bunk and upper bunk may not use the same mattress size.
Before ordering a replacement, identify your truck's model and sleeper configuration, then check the bunk's actual measurements. The original mattress label or the truck manufacturer's specifications may give you a useful starting point, but measuring the available sleeping space is the most reliable way to confirm the fit.
If your truck has a custom-built platform or an altered sleeper layout, pay particular attention to any dimensions that differ from the original setup.
How Do You Measure for a Replacement Semi-Truck Mattress?
If possible, remove the old mattress and measure the usable sleeping platform directly. An older mattress may have compressed, changed shape, or never fitted the bunk particularly well in the first place.
Before choosing your replacement, check these details:
- Width and length. Measure the available sleeping surface from side to side and from head to foot. Check more than one point if cabinets or other fixtures make the space irregular.
- Mattress thickness. Note the height of your current mattress and the clearance above the bunk. This is especially important for upper bunks, overhead storage, and beds that lift to reveal compartments underneath.
- Corners and unusual shapes. Record any angled or rounded corners, cutouts, or areas where the mattress needs to fit around built-in furniture.
- Bunk movement. If the sleeping platform folds, lifts, or converts into another configuration, check whether the mattress needs to bend or move with it.
Also consider how you'll get the mattress into the sleeper cab. A replacement that fits the bunk still needs to pass through the truck's entry and any tight interior spaces.
Which Mattress Material Should You Choose for a Semi-Truck?
The right material depends on the feel you prefer, how often you sleep in your truck, and any limits on mattress height or weight.
- Memory foam offers a more contouring feel. It may appeal to drivers who prefer cushioning around the shoulders and hips rather than the more responsive feel of a traditional spring mattress. Custom foam construction can also accommodate unusual bunk dimensions and thickness requirements.
- Latex foam has a more responsive feel, making it an option for sleepers who prefer less of the sinking sensation associated with some memory foams.
- Pocketed coil mattresses use individually wrapped springs that respond to movement and provide a different support feel from all-foam designs. They may suit drivers who prefer a more traditional mattress, provided the finished mattress's dimensions, height, and weight work with the bunk.
You can compare the available foam mattress options and pocketed coil mattresses to find a construction that suits your comfort preferences and sleeping space.
Don't Overlook Mattress Thickness
A thicker mattress isn't automatically a better choice for a sleeper cab. Extra height may reduce headroom, interfere with nearby cabinets, or make a lift-up bunk harder to operate.
At the same time, a thinner mattress still needs an appropriate comfort and support construction for the person sleeping on it. Rather than choosing thickness in isolation, consider how the finished mattress will feel and whether it fits within your bunk's available space.
When Does a Custom Semi-Truck Mattress Make Sense?
A ready-made truck mattress can work well when its dimensions, thickness, and construction match your sleeper bunk and comfort preferences.
A custom replacement is useful when your bunk falls outside commonly stocked sizes or has features that a rectangular mattress can't accommodate. You might need a specific width or length, a lower mattress height, shaped corners, or a construction suited to a bunk that lifts or folds.
Customization also gives you more control over the mattress's feel. Instead of selecting a factory replacement based on size alone, you can compare available materials and comfort options while keeping the finished mattress compatible with your truck.
Order a Semi-Truck Mattress That Fits Your Sleeper Cab
Before ordering, have your bunk's width, length, and maximum suitable mattress height ready, along with measurements for any unusual corners or other features.
At Custom Mattress, you can browse custom foam and coil mattresses and select the dimensions and available comfort options that work for your sleeper cab. If you're replacing a mattress with an unusual shape or a specific folding requirement, confirm the configuration before placing your order.
