Consider an Aftermarket Mattress

In terms of rest, relaxation, and comfort, the Peterbilt 579 is a good choice with a roomy cab for sleeping. The 579 also has ample shelving, storage, and other features that make a driver feel more at home. As with all sleeper semi-trucks, the 579 comes with a factory installed mattress. Even if you sleep well on the stock semi-truck mattresses with which sleeper trailers come equipped, you may find yourself considering a replacement for the OEM semi-truck mattress down the road. Be it wear and tear or simply age, you may decide to replace or upgrade the stock mattress to get more comfortable and consistent sleep.

While stock semi-truck mattresses from the manufacturer can sleep comfortably for a while, they are prone to common wear points and might not maintain the comfort you need during long hauls. SleepDog® offers a variety of quality, aftermarket mattresses which will undoubtedly upgrade the comfort and support of the bunk in your sleeper cabin. Every SleepDog® mattress is constructed with more supportive memory foam, more breathable material, and an additional layer of plush comfort to ensure more comfortably and reliable sleep. SleepDog® semi-truck mattresses are available in standard sizes, so you can be sure to find an exact size replacement for the stock Peterbilt semi-truck mattress.
