When it comes to choosing a mattress for your recreational vehicle (RV), size matters a lot. Not only does your mattress influence how well you sleep, but ensuring that your bed fits properly will help keep your vehicle functional and in great condition.
There are many standard RV mattress sizes, but there may be some variation between them depending on the manufacturer.
Because of this, it’s important to measure your RV and get a mattress designed by an experienced professional. Looking for the perfect mattress for your RV? Here’s everything you need to know about choosing the right size.
Get the Right Mattress Size for Your RV
Here are four steps you should take to get the right size for your RV mattress.
1. Measure the Bed
Measuring the best is the only real way to know the exact size of the mattress that fits in your RV.
You should also learn about the different RV mattress size ratings (more later in this article), but even these vary from one brand to the next. So, the best way to know the size and shop for the right mattress is by using a tape measure to determine the width, length, and height.
2. Understand Different Mattress Sizes
While it’s true that not all manufacturers follow the same standard, it’s important to note that a sizing system does exist for RV mattresses.
- RV Twin: 28-40” wide x 75-80” long
- RV Three-Quarter: 48” wide x 75” long
- RV Full: 53-55” wide x 75” long (shorter than a standard full)
- RV Queen (Short Queen): 60” wide x 74-75” long
- RV King: 72-75” wide x 80” long (or slightly shorter)
3. Work with a Company that Guarantees the Fit
One of the best ways to get a perfectly fitting mattress is by working with a company that does customized work. Slumber Ease, for instance, has extensive experience manufacturing mattresses for standard as well as custom RVs of all sizes.

How Do I Choose the Best Mattress?
With more than 11 million households owning an RV, having a comfortable motorhome is essential to making the most out of every trip. After all, the better you sleep, the more you’ll be able to enjoy time exploring new destinations and soaking in the different local cultures that make up our great nation.
In addition to your mattress size, here are 3 areas you want to pay close attention to when choosing the best mattress for your RV.
Softness Rating
The first variable that most RV owners look at is the softness rating on the bed. There is no formula to determine the best softness rating, so this varies from one person to another. Some people prefer softer beds, while others prefer mattresses that are firmer.
When speaking to your mattress manufacturer, make sure to inquire about the mattress’ softness. It’s also a good idea to consider what firmness you currently have at home and how well you sleep at night to help make the best decision.
Weight
The weight of every accessory in your RV matters, including your mattress. It’s in your best interest to choose a mattress that is on the lighter end in order to improve fuel efficiency.
That said, you should not sacrifice quality and comfort for weight, so avoid opting for mattresses that are light but provide no support.
Materials
Last but certainly not least, the materials of your mattress influence both its performance and price tag. Better materials like memory foam and hybrid layers will cost more, but they also tend to provide a more comfortable feel and last for longer.
How Do I Know What Size My RV Mattress Is?
You should be able to find out your RV mattress size in the user’s manual or the rig’s technical documentation. If you no longer have access to these details, it’s also a good idea to contact the manufacturer and inquire about the exact size of your mattress.
This is the reason why it’s a good idea to measure your bed and your current mattress. Measure the length, width, height, and depth of your mattress too so that you have a three-dimensional measurement.
If you’re still unsure about your mattress size, get in touch with Slumber Ease and we’ll help you get a mattress that fits perfectly.
Are RV Beds the Same Size as Regular Beds?
One of the biggest misconceptions surrounding RV mattresses is that they are just as big as normal mattresses. The truth is that rigs have a limited amount of space, so RV mattress sizes have been adapted accordingly.
In most cases, the rating adheres to the measurements listed earlier in this article, but it’s important to note that some variations exist among manufacturers.
Get the Right Mattress for Your RV
Getting the right mattress for your RV is the difference between struggling to get some rest and sleeping like a rock. With that said, there are many variables you need to keep in mind when choosing the right mattress size.
From measuring the actual bed to picking adequate materials, there are many steps you can take to help ensure the best mattress.
