If you’re looking to replace the mattress in your RV, you might have learned that RV mattress sizes are different than traditional ones. It makes sense, a smaller space calls for a smaller sleeping area.

The spaces inside RVs vary to accommodate smaller living arrangements. So that queen bed you’ve loved for three years in your home may not make it with you when you move into your RV.

If you’re looking to do some research on the many RV mattress sizes and what makes them different, read on!

How Are RV Mattresses Different from Traditional Versions?

You may have loved the king mattress that you slept on at your sticks-and-bricks house. However, the mattresses provided by RV manufacturers are lacking. One of the first upgrades many RVers do is replace that hard, uncomfortable poor excuse for a mattress.

There are many companies on the market that provide RV mattress sizes. In fact, they come in soft, medium, and firm options, just like a regular mattress. You can find innerspring, hybrid, memory foam, advanced cooling options, and more. 

As we mentioned above, RV mattress sizes are different from some traditional ones. Because of the space-saving techniques used in recreational vehicles, many mattresses come narrower and shorter than their traditional counterparts.

And you may have an RV model with sleeping spaces that fit your traditional mattress. So you might just get that king mattress in your new bedroom after all!

About the Different RV Mattress Sizes

Let’s look more specifically at the different RV mattress sizes. One of the most important steps during this process is to measure your space twice to ensure that you purchase the correct size. Don’t forget the headroom space, either. 

If you have overhead storage, or maybe the top of your bed sits in a slide, make sure to measure the space you’ll have at the top of the bed. If you want to sit up to read or watch TV, you’ll need to consider that when looking at mattress thickness.

RV Twin Mattress Size

An RV twin mattress is about 38×75 inches. An RV twin mattress size is not the same as a bunk, so again, make sure to measure. You’ll find bunk mattresses much smaller than typical.

Truck Mattress Size

Truck campers have their sleeping quarters over the cab. This space generally fits a mattress measuring 35×79 inches or 42×80 inches. Sometimes you’ll even find a queen-size bed at 60×80 inches that will work in this space.

RV Bunk Mattress Size

As mentioned above, RV bunk mattresses are not twin-sized. They are narrower to provide more space for play. Bunk beds are a great way to give each child their own sleeping space. And to do this, they come in a variety of sizes, so make sure to measure your bunk beds in particular.

In fact, your top bunk may not be the same size as your lower bunk even though they’re in the same room. You’ll find 28×75 inches, 30×75 inches, 30×80 inches, and more.

RV Full Mattress Size

RV full-size mattresses come in full and short-full. The RV full will measure around 53×75 inches, while an RV short-full will be shorter and narrower at 48×74 inches.

RV Queen Mattress Size

The RV queen also comes in two options: queen and short queen. An RV queen mattress will measure around 60×80 inches. The RV short queen mattress measurew about 60×75 inches. Manufacturers create these shorter and narrower versions for owners to walk around the bed. 

Sometimes the bed is only inches from the wall or dresser, so a shorter mattress creates additional space. However, if you’re tall, a short bed may be uncomfortable because your feet will hang off the end.

RV King Mattress Size

A standard eastern king mattress is 76×80 inches. This is what you have in your sticks-and-bricks house. Although it’s possible to fit this size mattress in your bedroom in your RV, you want to measure first because an RV king bed is not the same size. 

The traditional RV king measures 72×80 inches. You can also get an RV short king mattress at 72×75 inches.

What Size Are Most RV Mattresses?

RV mattress sizes vary. There is no one-size-fits-all even among the same category. As previously mentioned, bunk beds could measure 34×75 or  30×80 inches. Those are two very different sizes. 

Short queens are more common in smaller campers because of less space in the bedroom. But larger fifth wheels and Class A motorhomes have more room and can accommodate larger-sized mattresses.

Can You Use a House Mattress in Your RV?

You might fit your mattress from home into your RV. Some of the dimensions will accommodate standard mattress sizes. However, consider how you’ll get the bed into the RV before running to the bedroom to move it.

RV doors are narrow and shorter than the doors in your house. Can you squeeze it through the hallway and doors? Even though the mattress might fit in the space, you might not get it back to the bedroom.

Are RV Mattresses Thinner Than Normal Ones?

The RV mattresses that come standard are thinner than traditional ones. They usually measure five inches thick. Many RV owners change to a more comfortable one, especially those with back pain or health problems. 

Sometimes you can change it out for a traditional one, and other times you’ll need to change it out for an RV mattress size. You can purchase thicker mattresses with better quality than the ones that come with your rig.

How Thick Should an RV Mattress Be?

RV mattresses can range in thickness from 5″ to 12″. When deciding how thick you want your RV mattress to be, you need to take a few things into consideration.

First, how much weight do you have to spare? A thinner replacement mattress is going to weigh less than a luxury padded one. If your mattress is going to be in a slide, you’ll want to figure out the weight limits for that slide out as well.

Secondly, are there any built-in shelves around the bed? If you get a mattress that is too thick, you might end up having to remove a shelf or two. Not only is it important to measure length and width for your new mattress, but height as well.

Carefully measure your space and then do some homework to find the best mattress solution. Maybe it’s your own mattress from your house, or maybe you have to find a unique RV mattress size.
