  • The first step to buying a replacement RV mattress is to figure out what size you need to order.

    Most people will measure the mattress. You can do this if you’re in a hurry.

    However, the most accurate way to do it is to measure the dimensions of the surface the mattress rests on. Usually the mattress is placed on ply-wood or some type of similar surface.

    There are two reasons why this is more accurate. The first being that your rv mattress may not be the same size as it was when the RV was built. This can be due to fluctuations in temperature during off-season storage (especially you folks in Arizona!) or from exposure to UV light if the RV was kept uncovered during storage.

    In addition, RV mattresses are made by both humans and machines. If you take 10 out of stock, you will get a slight variation in size. If you measure the RV mattress instead of the surface it lies on, it may lead you to believe that you need a custom mattress size.

    The most common RV mattresses are in the shape of a rectangle.
