RV beds tend to have different measurements to standard bed sizes, in order to make the best use of limited space. And these vary a lot from vehicle to vehicle. So before you shop for RV mattresses, you need to carefully measure the beds inside your RV. Then compare your measurements to the table below, to find out which standard RV mattress size you need.  Although some of the models in our best mattress guide are available in RV sizing, it’s not quite as straightforward as shopping for a king bed size or queen bed size, for example. When you shop for your RV mattress, don’t just assume the retailer you’re buying from follows the standard sizes we detail below. They should, but in practice not everybody does, so always read the measurements of the mattress in the small print to make sure.

How big is an RV bunk bed?

So it’s vital to measure your bunk bed carefully, and check that they match the retailer’s stated size for each individual mattress.
