RV Mattress Size Dimensions and Size In Inches

Amazon

You may have noticed a lot of clever engineering and design in your RV. When your living space is that small, manufacturers and RV designers do everything they can to make every space, and every bit of weight in your rig work as hard as it can so that you have everything you need in that tiny little home on the road.

Which means they changed the sizes of the beds.

If you’ve ever tried replacing your RV mattress with a standard sized one, you already know this – they aren’t the same size. RV mattress sizes are different than standard mattress sizes. Manufacturers shave a few inches off the length, and sometimes the width, of mattresses in order to eek out as much possible space and to save as much weight as they can in your motorhome.

So if you’re in the market to replace an RV mattress, you should familiarize yourself with the different RV mattress dimensions so you’re sure to get the right fit. Here’s the breakdown:

RV mattress sizes

  1. Twin mattresses

Often, thanks to those space-saving measures, RV twin beds are disguised as seating. Perhaps your dinette turns into a twin bed, or your chair or couch converts into a bed. They may also be arranged side by side or as bunk beds. Twin mattresses do, actually, measure the same as a single bed at home – 39”x75”. Twins generally accommodate one adult sleeper, though taller adults may have trouble. They can also accommodate one child…or perhaps two if they’re small (just line ‘em up in there like crayons in a crayon box!).

  1. Full mattresses

The RV mattress size for full beds in the same as a double bed. An RV full measures 54”x75”, while a domestic full mattress is 53”x75”, one inch narrower (about the only time an RV mattress will be bigger than its domestic counterpart).

  1. Queen RV mattress sizes

Oddly enough, there are three different possible queen mattress sizes.

  • A standard queen measures 60”x80”. In an RV, this is also called a regular queen.
  • A three-quarter queen mattress measures 48”x75”
  • A short queen measures 60”x75”

If you’re shopping for a queen-size RV mattress, be sure you know which of these sizes you need!

  1. King RV mattress sizes in inches

A king RV mattress is as long as a standard king (good news for tall sleepers!), but it’s narrower. Standard king mattresses measure 76”x80”, while an RV king measures 72”x80”. If you’re sharing a bed, this gives each person the space equivalent of an extra-long twin bed.

How to choose the best RV mattress

Once you know the kind of mattress you need, it’s time to start looking around for the perfect mattress for your rig. Camping supply stores like Camping World often sell RV mattresses, and you can find them online at places like Amazon and Overstock.com as well.

You can also look into having a custom RV mattress made. This is going to be a more expensive option, but it will ensure that your mattress fits exactly in your space.

As with anything you purchase, read about your mattress first and look at reviews on websites or forums. Nothing can replace talking to actual people who have used the product you’re interested in, and you can gain a lot of insight by reading what they have to say. Also, find out the return policy of the store you’re purchasing from. Many, but not all, will allow you to return the mattress if you try it out and find it to be uncomfortable or not what you wanted.

With a little research and patience, you’re sure to find the RV mattress that suits you and your family perfectly!
