Mattress dimensions can vary widely depending on the truck manufacturer and even between different sleeper cab layouts within the same model. For the best fit and comfort, it’s important to measure your exact sleeper berth rather than relying on assumed or standard sizes.

Measuring Tips for the Best Fit

• Measure before you buy: Use a tape measure to record the precise width and length of your sleeper platform before selecting a replacement mattress.

• Account for mattress thickness: Make sure there is adequate headroom once the mattress is installed. In most sleeper cabs, a mattress up to 10 inches thick offers the ideal balance of comfort and usable space.

• Home mattress sizes aren’t a perfect match: Residential mattress dimensions (for example, a twin at 38″ x 75″) are typically slightly different from truck-specific sizes, which can result in wasted space or poor fit in a sleeper berth.
