What Size Mattress Fits in an International LT Series?

International LT Series Black

The International LT Series semi truck is a high-ranking truck designed specifically for long hauls by a company that is a leading producer in the transportation industry. With the harsh demands of truck driving, professional drivers deserve a truck that will safely transport themselves and their load while providing a private space to rest and relax on the road. The International LT Series sleeper cabin does just that, making it the perfect home away from home.

About the International LT Series

The International LT Series is another top-rated truck in the transportation and logistics industry largely due to its durability, reliability, and overall safety. Available in four different configurations: a 56” low roof sleeper, a 56” hi-rise sleeper, a 73” hi-rise sleeper, and a 73” sky-rise sleeper, the International LT Series can be customized with a “build your own” option to ensure it is equipped to meet exactly your long haul needs. When building your own International LT Series, you can choose the cab, exterior color, exterior and interior trim upgrades, and the engine. In addition to the available customizations, there are standard features and enhancements that come with your truck no matter the customer specifications. Such amenities include:

  • All controls within reach: The driver controls have been positioned according to how frequently they are used. The more frequently used controls are located close to the driver, but everything is within arm’s reach.
  • Collision mitigation: The Bendix Wingman Fusion collision mitigation technology consists of a forward-facing camera and radar. These two features provide Adaptive Cruise Control, Lane Departure Warning, road speed sign detection and stationary object alerts.
  • Improved visibility: The sloping hood, large side windows, and door mirrors provide industry leading visibility in front of and alongside the vehicle. There is even blind spot detection technology, which uses a radar to monitor the blind spots and provide the driver with blind spot alerts.

Inside the Sleeper Cabin

The sleeper cab inside the International LT Series was made to make you feel more at home. Some of the standard conveniences include a 12-volt power supply, sleeper windows, and a sleeper control panel. Additional amenities include a windshield curtain and microwave or TV accommodation. The various sleeper cabin configurations come with a number of storage options, as well. In the 56” low roof and 56” hi-rise sleepers, there are several compartments and cabinets for overhead and rear wall storage. In the 73” hi-rise and sky-rise sleepers, you have the option for wardrobe tower cabinets, dresser cabinets, or refrigerator storage. All configurations of the International LT Series sleeper cabins even have adequate room for the bunk you’ll be sleeping in. Both 56” inch sleepers come with a 36 inch by 80 inch innerspring mattress, while the 73” sleeper with upper bunk comes stocked with a 33 inch by 80 inch mattress, and the 73” sleeper with lower bunk accommodates a 42 inch by 80 inch bed.

Mattress Upgrade

While the innerspring mattress stocked in your International LT Series sleeper cabin is a convenient feature, the OEM mattress will likely need to be upgraded sooner than later. Of course, finding a semi truck mattress upgrade is easier said than done because your mattress size will vary depending on your semi truck sleeper configuration. In the International LT Series trucks, you will likely get a bunk size of 36 inches by 80 inches, 33 inches by 80 inches, or 42 inches by 80 inches depending on the sleeper you purchase. All three of these mattress sizes are relatively common within the trucking industry, and often sold by specialty truck mattress retailers like SleepDog® Mattress. However, because the mattress sizes found in the International LT Series truck line differ, the best way to ensure you are upgrading to a mattress that will work for your space is to measure the mattress that came stocked in your sleeper cabin, in addition to your sleeper berth.
