Different Types Of Rv King Mattresses

When it comes to RVs, the king mattress is a blanket term, and you cant just order one without specifying the type of mattress. There are three types of RV king mattresses:

  • Standard King Mattress This is the most common type of king mattress for RVs. They measure 72 x 75 inches to 72 x 80 inches and can comfortably fit 2 adults. Most medium-sized and large RVs can fit a standard king mattress.
  • Eastern King Mattress This type of mattress is more commonly found as a built-in option for newer models, although you can find solo mattresses as well. Eastern King mattresses measure 76 x 80 inches, giving you a thicker mattress without losing any of the length. This type of mattress is best for people who want a thick and comfortable mattress.
  • CalKing Mattress The CalKing is not typically used for RVs because they are longer compared to other types of king mattresses. CalKings measure 72 x 84 inches and can take up a lot of room in an RV because of the added length. If you have an RV with a long room with limited width, you can consider using a CalKing mattress.
  • Full : 54 Wide X 75 Long

    The Full is also known as a Double. Unfortunately though the term Double doesnt quite suit this size because 54 divided by two is 27 of space per person, which is not much at all when sharing. The Full size, however, is an excellent option for single use. Like other mattresses of a similar length, this one would best suit someone under 6ft.
