Rather than pay for a room, many semi truck drivers opt for a sleeper cab to save time and money on the road. But what size is a semi truck mattress, and where can you get the right mattress for your sleeper cab? While there’s no standard semi truck mattress size, the majority are around 80 inches long and 40 inches wide. That said, semi truck mattress dimensions will vary greatly depending on your make and model. Find out what semi truck mattress size you need with the guide below from International Used Truck Centers.

What Semi Truck Mattress Size Do I Need?

What size is a semi truck mattress for most sleeper cabs? With so many semi truck models on the market, there’s no one-size-fits-all solution when it comes to your semi truck mattress. While some models may use the same size mattress, many have their own unique specifications — and things get even more complicated when you venture into custom cab territory. Keep these points in mind as you start shopping for a semi truck sleeper mattress:

  • The thickness of the mattress usually won’t matter, but you’ll need the exact length and width.
  • While it’s possible that a standard size mattress will fit inside your truck, many require a semi truck mattress made specifically for sleeper cabs.
  • Use our guide below to find the right semi truck mattress, or check your owner’s manual for the correct specs.
