Can You Fit a Full Mattress in a Sleeper Trailer?
When it comes to equipping a tractor trailer sleeper with a mattress that properly fits, one question that might come to mind is whether or not sleeper trailers can accommodate full-size truck mattresses. Most semi-truck mattresses measure around 80 inches in length and 40 inches in width – not quite as wide as a full size. While a full-size mattress might fit like a glove in some sleeper trailer trucks, others might be missing a few crucial inches that allow a full-size mattress to fit comfortably. Additionally, full-size mattresses may not comply with DOT guidelines for your truck model. So, before buying a new full-size mattress for your sleeper trailer, measure your available space to make sure it will actually fit.

Differences in Models
Every sleeper trailer truck make and model is likely to have different bunk dimensions inside the sleeper cabin. On top of that, different truck and sleeper cabin options may also affect the size of the bunk, which means that some sleeper trailers may have different mattress size requirements, even if they are the same make and model. You may be tempted to purchase a high quality aftermarket full size mattress for your truck, but it is best to hold off until you know that your tractor trailer can fit a full-size mattress. Fortunately, while your truck may not fit a full-size mattress, it should fit most standard mattress sizes available for semi-truck sleepers. If you cannot fit a full, you will most likely be looking into one of the following sizes: 42 inches by 80 inches, 39 inches by 80 inches, 36 inches by 80 inches or 32 inches by 80 inches.
Make Sure to Measure
Before purchasing a full-size mattress, it is important to make sure you get the correct measurements for your exact semi-truck make and model. The easiest way to go about doing this is by simply hand measuring the mattress that your truck is currently equipped with. If, however, you are unable to take these measurements, either because the truck is not owned by you or it is currently unavailable, you can often find charts that include common measurements for a variety of semi-truck models. Due to the fact that measurements can vary by a few inches between any two makes and models of sleeper trailers, it is important to get the correct mattress measurements before committing to a full-size mattress purchase. Again, since only a few inches could mean the difference between a perfect fit and a disappointing return shipment, you will need to make sure you accurately measure the width and length. For some fittings, you may even have to measure the depth of the mattress.
Other Options and Custom Sleeper Trailer Beds
After taking time to accurately measure and correctly identify your model of semi-truck and find that your space still appears unable to accommodate a full-size semi-truck mattress, there is another option if you are set on getting that full-size mattress upgrade. While it definitely comes at an extra cost, some trucking professionals and enthusiasts take it upon themselves to modify their existing space. Sleeper cabins with specifications that would otherwise not allow for a full-size semi-truck mattress can be modified to fit a full-size mattress. Some truckers have even been known to install other amenities such as a sink, stove top, or even a large refrigerator unit. Upgrading your sleeper cabin for additional comfort may be worth it and can be accomplished with some elbow grease and a DIY mindset.
If upgrading your truck’s sleeper is not a viable option, you can simply purchase a standard mattress size to fit your bunk space. Outlets like SleepDog® mattress offer nearly all standard sizes of mattresses for tractor trailer sleeper bunks. Another option to consider is purchasing a memory foam mattress topper to provide extra comfort without having to worry about fit specifications for the larger mattresses.
As the somewhat cliché and age-old adage goes: “Measure twice, cut once”. When buying a full-size mattress for a tractor trailer sleeper, the saying holds true. Even if you do not have the exact space requirements for a full-size, you may still be able to get that mattress you want for your trailer. SleepDog® offers two great lines of mattresses in four of the most popular standard sizes for sleeper trailer bunks. You can also choose from two different SleepDog® mattress topper options, whether you want to buy one with a new mattress or if you simply want to add a topper to the mattress you already own.

Frequently Asked Questions
Can you use a standard full mattress in a semi truck?
A standard full mattress is 54” wide x 75” long. This is wider and shorter than the overall dimensions of most semi truck bunks, which measure 80”long and 32-42” wide for the bunk. A full size mattress could technically fit in some truck sleeper cabs which have more space, but not all semi trucks are built to fit a true full mattress. It is always a good idea to measure your sleeper berth before purchasing a mattress. You should know if the extra width will cause an issue or discomfort in the berth.
What’s the difference between a full-size and a truck mattress?
The main difference between a full-size mattress and a truck mattress is the dimensions, and construction. A full mattress size is 54” wide x 75” long. Most truck mattresses are going to be narrower, and 80” long to fit into the sleeper berths. Truck mattresses are also designed with over the road comfort in mind, with technology for motion isolation, durability, and supportive foams that were developed to help drivers get solid quality rest, when the truck is parked, and even in some cases the truck is in motion.
How do I measure my sleeper berth for a new mattress?
To measure your sleeper berth accurately, remove your bedding and measure where the mattress will lie. Record the length and width in inches; if possible, also note the depth for mattress thickness. A few inches can be the difference between a snug fit and a return, so measuring is essential. If you cannot measure directly, check your truck’s manual or the specifications from the manufacturer’s website for mattress size information.
Do truck mattresses come in different thicknesses?
Yes, truck mattresses come in thickness options based on your comfort needs and space in your sleeper berth. Typical truck mattresses are about 6” to 10”. If your top bunk is used for sleeping, and the sleeper berth is on the smaller side, a thinner mattress may work better. A thicker mattress will provide additional cushioning, which improves long-haul trip comfort. When shopping, thickness, foam density, and support system are also important to getting durability and rest.
Can I cut down a regular mattress to fit my truck?
Technically, you could slice a regular foam mattress to mold it to your sleeper bunk but it isn't advisable. It's too risky to cut or alter a mattress as it may compromise its support, durability and structure for an uncomfortable and potentially unsafe mattress. Truck mattress brands such as SleepDog® make mattresses for sleeper bunk dimensions so they are suitable for use; a mattress is the correct size, purposely built for use in a truck sleeper. It's a good idea to select the mattress from the start, as an investment you will make a better purchase and ensure a better comfort and performance.
