Mattresses For Peterbilt Trucks
Driver rest quality has a direct impact on safety and performance — a fatigued driver is one of the leading causes of commercial truck accidents. For owner-operators and long-haul drivers spending nights in the sleeper, a quality mattress is one of the most important investments in the cab. We carry replacement mattresses sized for Peterbilt sleeper berths, available in various thickness and foam density options to suit different comfort preferences and sleeping positions.
Frequently asked questions about mattresses
What size mattress fits a Peterbilt sleeper?
Peterbilt sleeper berth dimensions vary by model and sleeper configuration. The 72-inch and 80-inch mid-roof and raised-roof sleepers on models like the 579 and 389 use mattresses that are typically 42 inches wide by 80 inches long, though dimensions can vary by cab generation and bunk configuration. Always measure your existing bunk platform before ordering — even a few inches of difference can mean a mattress that doesn't fit properly or leaves gaps at the edges.
What mattress thickness and foam type is best for a truck sleeper?
For most over-the-road drivers, a 4–6 inch mattress with a medium-density foam core provides the best balance of support and space efficiency in a sleeper bunk. Memory foam toppers add comfort without significantly increasing mattress height. Drivers with back pain often prefer firmer, higher-density foam that provides better lumbar support during rest periods. Avoid very thick mattresses in sleepers with limited headroom above the bunk, as they can make entry and exit awkward and may compress against the bunk ceiling.
How often should a truck sleeper mattress be replaced?
A quality truck mattress used for regular overnight rest should be evaluated for replacement every 3–5 years, or sooner if it shows visible sagging, loss of support, or foam breakdown. Mattresses in trucks used for occasional rest stops may last longer. A mattress that's lost its shape won't recover regardless of how it's positioned — foam that no longer springs back under pressure has exceeded its useful life and should be replaced to protect driver health and rest quality.
