A custom maker can build a truck sleeper 42 × 80 mattress to your exact inches, including rounded or cut corners. Stores rarely keep this size on the floor.
How it compares with the sizes people mix it up with.
| Size | Inches | Sleeping area | Compared with truck sleeper 42 × 80 |
|---|---|---|---|
| Truck sleeper 42 × 80 | 42 × 80 | 23.3 sq ft | This size |
| Truck sleeper 35 × 79 | 35 × 79 | 19.2 sq ft | 7″ narrower, 1″ shorter |
| Twin XL | 38 × 80 | 21.1 sq ft | 4″ narrower |
| Full XL · 54-inch | 54 × 80 | 30 sq ft | 12″ wider |

A 42 × 80 inch mattress fits the larger sleeper cabs on many newer semi-trucks. It’s 4″ wider than a twin XL at the same length.
Many larger cabs take 42 × 80. Some take wider custom sizes. Measure the bunk.
Check the usable width and length with any safety restraints, storage access, and sleeper fittings in place. Confirm finished dimensions with the seller. A standard twin XL is usually narrower. Do not assume a twin XL fitted sheet or platform will work with a 42-inch-wide mattress.
52 of the 52 Truck sleeper 42 × 80 mattresses we list can be returned under the seller’s trial. Made-to-order mattresses often can’t. Each one’s return terms are in its details.
Mostly online from the brands on this page, which ship to most US addresses. Local mattress factories can build one; stores rarely keep this size on the floor.
Prices change often, so we link to each seller instead of listing them. Odd sizes are often priced at or above the nearest standard size, and made-to-order ones usually cost more.
Usually not. Owner feedback is about the mattress model, often in a more common size. Each summary says whether it’s about this exact model, and links to the source.
