If your RV interior doesn’t feature a bed, you might as well drive a car around the US. Your RV bed is critical to your road trip comfort, but there’s a lot you need to know about RV mattresses to make your RV bed the most comfortable bed ever.
It all starts with a quality mattress selection, and you might think you already know mattresses because you’ve probably slept on them for most of your life. RV mattresses are a little different, and here are some helpful tips you should know.
Are RV Mattress Sizes Different?
Many RV mattresses are different than standard residential sizes. A queen RV mattress in an RV differs from a residential queen mattress. This means you can’t make any assumptions when shopping for an RV bed.
Other sizes are sometimes the same as their residential counterparts, such as twin and full (aka double) beds. King-size beds in RVs are usually narrower than residential mattresses. Here’s a breakdown of RV mattress dimensions:
RV Mattresses | Dimensions (in inches) |
California King | 72 x 84 |
Eastern King | 76 x 80 |
RV King | 72 x 80 |
RV Short King | 72 x 75 |
RV Queen | 60 x 80 |
RV Short Queen | 60 x 75 |
RV Full/Double | 53 x 75 |
RV Three-Quarter | 48 x 75 |
RV Bunk | 28-35 x 75-80 |
RV Twin | 25 x 75-80 |
Truck Bed Mattress | 35-42 x 60-80 |
Some of these dimensions match what you’d find in a mattress store. For many RVs, shorter beds are preferred to provide space to move around the bed on either side.
