The Mattress That Comes With a Freightliner

The foundation of the trucking industry in America is the Freightliner truck. Professional drivers rely on these heavy-duty vehicles because of their dependability and cutting-edge technology. Freightliners are built to last, whether you're transporting cargo across the nation or making local deliveries. However, the quality of sleep truckers get while making long hauls in a Freightliner is often an afterthought. The factory-installed mattress is primarily intended to satisfy basic sleep needs at the lowest possible cost, which might make a truck mattress upgrade necessary sooner rather than later.

The SleepDog® Solution

SleepDog® mattresses are designed to offer the same degree of support and comfort that you expect from a premium mattress at home, while on the road, and in a selection of sizes that are compatible with most Freightliner sleeper cab configurations.

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.

Find Your Mattress Size by Freightliner Model

Selecting the correct mattress size for your truck model is essential for the safest and most comfortable fit. Here is an overview to help you choose the ideal SleepDog® mattress size for your sleeper truck configuration:


Freightliner Cascadia

Freightliner Cascadia

Depending on the year and configuration of your sleeper cab model, the Cascadia can typically accommodate a Size A 36" x 80", Size B 39” x 80”, or Size C 42” x 80” SleepDog® or BigDawg® mattress.

Freightliner Columbia

Freightliner Columbia

Columbia sleeper cabs were available in four spacious configurations and frequently outfitted with a 32” x 80” bunk mattress or a Size A 36” x 80” mattress.

Freightliner Coronado

Freightliner Coronado

The Coronado was available in four different sleeper cab configurations, most of which were equipped with a Size D 32” x 80” bunk.

Freightliner Century Class

Freightliner Century Class

Available in seven different sleeper configurations, the Century Class frequently came stocked with a Size B 39” x 80” mattress. If looking to upgrade, your Century Class sleeper may also be able to accommodate a 38” x 80” Twin XL.

*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.

Get More Rest in Your Freightliner with a SleepDog® Mattress

More than just a place to crash, your sleeper cab serves as a location to refuel before taking on the long haul ahead. Your Freightliner's performance will be significantly enhanced with a SleepDog® mattress that is engineered to provide the perfect combination of comfort, support, and durability.
