Truck Mattress Size Guide
Always measure before ordering. Dimensions vary by trim level, model year, and factory options. The sizes below are reference values only.
How to Get the Right Size
Choosing the right size mattress for your sleeper area doesn't have to be a headache. Follow these five steps before placing your order.
Check Your Current Mattress
Replacing a worn-out mattress? Before you toss it, check if it fits your sleeper space well...
Read the Law Label
If your old mattress fits well, look for the legal label sewn onto the end of it. The tag reads "UNDER PENALTY OF LAW, THIS TAG NOT TO BE REMOVED EXCEPT BY CONSUMER." It lists all materials and the finished size — length, width, and height. Jot it down or take a photo before ordering.
Grab a Tape Measure
If there's no law label, measure the length, width, and height of your current mattress. If you don't have one, measure the interior of your cab's sleeper platform. Measure width at both ends and the middle — cabs aren't always perfectly rectangular. Standard truck mattresses run 6–9 inches thick.
Account for Thickness
Check your headroom clearance before choosing a mattress height. In most sleeper cabs, up to 10" thick gives a good balance of comfort and usable space. Upper bunks typically need 3–5" to leave enough headroom. Don't sacrifice sleep quality for a mattress that doesn't fit the space.
Ask Your Truck Manufacturer
If all else fails, contact the company that made your semi truck to get the official specs for your sleeping area. Use the manufacturer links below to find an email address or phone number. They can confirm the exact berth dimensions for your model year and trim level.
