The Mattress That Comes With a Peterbilt

While Peterbilt trucks are designed to perform dependably, Peterbilt mattresses are usually not up to that same challenge. Your stock mattress might be fine for a quick nap or the occasional overnight break, but it may fall short of providing sufficient support. Due to this issue, many Peterbilt truck drivers opt for high-quality aftermarket mattresses, like SleepDog®, to ensure they get the rest they need.

The SleepDog® Solution

SleepDog® mattresses are designed to meet truckers' unique sleep needs in a selection of sizes that are compatible with most Peterbilt sleeper cab configurations. Here's what sets SleepDog® mattresses apart:

Advanced Support

SleepDog® mattresses are constructed with multiple layers of high-density foam to provide unmatched support, eliminate pressure points, and encourage proper spinal alignment.

Peterbilt 389

The 389 is available in four different sleeper cab configurations, most of which are equipped with a Size A 36” x 80” or Size C 42" x 80" mattress.

Available in a number of sizes and configurations, the 567 is most compatible with our Size D 32” x 80” bunk mattress or our Size C 42" x 80" mattress.

*Please note: When looking for a replacement mattress it is important to know the exact measurements of your sleeping area. While most sleeper cabins accommodate standard semi-truck mattress sizes, the best and most accurate way to measure for your new mattress is to measure the width and length of your sleeper berth.
