The Best Semi Truck Mattress for Your Over the Road Sleeper

Long, overnight drives can really make a truck driver appreciate (or downright hate) their over the road sleeper. Feeling comfortable and getting a good night’s sleep is just as important on the road as it is at home. With so many sleeper semi-truck brands and models to choose from, it is important to consider the overall comfort and livability they provide before choosing one. Of the utmost importance is the quality of the mattress in your sleeper cabin. Every sleeper semi-truck comes with a stock mattress. However, most OEM truck mattresses cannot compare to the comfort and support of an aftermarket replacement truck mattress like SleepDog®. While there are many other features to consider, such as cabin space, mattress length, storage, and relaxation amenities, the best sleeper semi-truck tractor units stand out with an impressive score for driver comfort, ergonomics, and productivity features.

TruckersTraining.com is also an excellent resource for those seeking a career as a truck driver or entryway into the trucking industry. They provide their top recommendations for sleeper semi-truck units based on the features, amenities, and driver popularity of each model. Their recommendation list includes the Volvo VNL 860, the Kenworth T680, the Peterbilt 579, and the Freightliner Cascadia.

Volvo VNL 860

Volvo VNL 860

The VNL 860 sleeper cabin comes with a roomy 77-inches of sleeper space, making drivers feel relaxed and closer to home.

Overall, the VNL 860 creates a comfortable and calm work and sleep environment for drivers. The VNL 860 also offers one of the first integrated reclining bunks in a sleeper. The bunk is fully adjustable, so it is like having your favorite recliner in your cab with you. The reclining bunk can also efficiently be stowed away to make room for an optional table and workstation configuration. SleepDog® offers a variety of quality, aftermarket replacement mattresses which will maximize the comfort and support of the sleep space in your sleeper cabin by offering more supportive memory foam, cooler, more breathable cover material, and thicker, more substantial mattress padding. The two mattress options SleepDog® offers come in standard sizes, so you can be sure to find the perfect replacement for the stock Volvo semi-truck mattress, while also getting a more comfortable and reliable sleeper mattress.
