In an effort to sleep as many people as possible, RV manufacturers have carefully customized bed sizes. The result is that some mattresses are smaller than their domestic counterparts and use a built-in bed frame without box springs. Though the sizes cover width and length, mattress depth can also vary. There are several factors to keep in mind before selecting the right mattress size, such as the height of the tallest person who will be sleeping in it, desired space for sleeping, and the space the mattress will inhabit. A list of mattresses and their dimensions are below.
Often disguised as seating, twin---also called single---beds may also be arranged side by side or as bunk beds. These mattresses measure the same as a single bed at home: 39 inches by 75 inches. Twin mattresses can accommodate one child or one adult sleeper, although the length could be a bit too short for taller adults.
This is the same as a double bed. An RV full bed measures 54 inches by 75 inches, while a domestic full mattress is 53 by 75 inches, 1 inch narrower.
A standard queen bed measures 60 by 80 inches. A queen size can be good for growing children and even taller adults or couples who prefer sleeping closer together. In an RV this size is called a regular queen. RVs also have a three-quarter queen, which is 48 by 75 inches, and a queen short, measuring 60 by 75 inches.
An RV king has the same 80-inch length as a regular king mattress but is narrower, 72 inches instead of the standard 76. King beds are generally the best choice for couples. Each person will have a sleeping space equivalent to a twin extra long mattress. It is also ideal for growing families or for pet owners who may have their pets sleeping with them.
