To answer this, we need to look at the average truck bed lengths. There are two typical bed lengths, short bed, and long bed trucks.
- Short bed trucks are the "typical" standard bed size and are commonly between 5.5' (compact short bed) to 6.5’ (most common) long.
- Long bed trucks are usually between 7’ and 8’ long depending on the year, make, and model.
A king size mattress measures 6.3’ x 6.6’. While you might need to lower the tailgate, theoretically you can absolutely transport your king size mattress (or any mattress) in the bed of your pickup truck (it won’t lay flat in the bed). As with any cargo in your truck, make sure to properly strap down your mattress so it doesn’t fly off.
