RV bunk size mattresses are good for small sleepers. This includes kids, teens, or short adults. A bunk mattress allows you to maximize your sleeping space. Bunk bed size ranges from 28 inches by 75 inches to 35 by 79 inches. 

Three Quarter Size

Smaller-framed individuals find a three-quarter sized bed to be spacious enough. Single adults or several children can sleep comfortably on a bed of this size.  A three-quarter size mattress measures 48 inches by 75 inches. You can use this bed in place of a full bed if space necessitates it.

RV Full/Double Size

RV Short Queen

Some RVs do not have room for a standard queen mattress. This is where a short RV queen bed comes into play. This mattress measures 60 inches by 75 inches. A short queen bed will comfortably sleep two adults. If you have the room, you can also use a regular size queen mattress (60 inches by 80 inches). 

RV King Size

For those who prefer ample room when they sleep, an RV king size mattress is perfect. This makes it a fantastic option for couples who co-sleep with their children. Your RV king bed measures 72 inches by 75 inches and 72 by 80 inches, while standard king size mattresses measure 76 by 80 inches. 

Types of RV Mattresses

The level of comfort and support you receive from your RV mattress depends on the type of mattress you go with. In addition, the cost of your camper bed depends on the size and type of mattress you buy. 

Air Mattress

An air mattress is a suitable option for sleepers who don’t have any health conditions or issues with joint pain. If you’re shopping on a budget, an air mattress is a great option. Air mattresses are less durable and don’t hold up as well as traditional mattresses. 

Latex Mattress

A natural latex mattress is ideal for sleepers who want responsive support. This allergy friendly mattress won’t attract mold, bacteria, or dust. The one downside to latex mattresses is it’s cost. The higher cost is due to natural and environmentally friendly manufacturing. 

Memory Foam Mattress

With this type of mattress, you’ll receive body-hugging support all night long. A memory foam mattress can lessen joint pain and muscle soreness. If you can, spend the extra money on a cooling gel memory foam mattress to stay cool all summer long. 

Hybrid Mattress

Hybrid mattresses are the perfect solution for sleepers who want the benefits of both latex and memory foam mattresses. This mattress provides you with tension relief via several layers of comfort support. A hybrid mattress also keeps you cool. The downsides to a hybrid bed are its higher cost and heavier weight. 

RV Mattress Toppers

Adding a mattress topper to your RV mattress can increase the plushness or firmness level of your mattress. This enables you to get the right level of support without investing in a completely different mattress. The right RV mattress topper can also help personalizing the feel of a mattress by increasing the softness or firmness.

Latex Mattress Topper

A latex mattress topper adds a responsive layer of support to your mattress. This type of mattress topper aids in releasing tension and relieving your pressure points. The allergy-friendly design of a latex mattress topper allows it to naturally ward off bugs, dust, and bacteria. 

Memory Foam Mattress Topper

You can increase the contouring and body-hugging support of your mattress by adding a memory foam mattress topper to it. This mattress topper can reduce the chances that you’ll wake up stiff in the morning. Memory foam material is great for those who have joint issues or athletes with sore muscles. 

Featherbed Mattress Topper

Add a featherbed mattress topper to your bed for a plusher feeling. This mattress topper is comparable to a pillow top mattress. Featherbed toppers hold up well over time when properly taken care of. You can shake your topper out every so often to help it maintain its fluffy and plush feel. 

Wool Mattress Topper

A wool mattress topper is recommended for a variety of different climates. This soft and supportive mattress topper keeps you comfortable regardless of the temperatures outside. Wool toppers increase the lifespan of your mattress. 

Do I Need to Buy an RV-Specific Mattress?

You do not need to buy an RV-specific mattress. You’ll first need to measure the mattress slot. Some RVs come with a manual telling you how big your bed slots are. If this is the case, you’ll know what size mattress you need.

Buying an RV specific mattress ensures you are maximizing your available space. This lowers the chance of sliding and experiencing fitting issues. Available RV mattress sizes are based on bed slots that come standard with travel trailers. 

What’s the Best RV Mattress for Me?

There are many different factors that need considering when choosing a mattress for your RV. Chief among these factors is number and size of sleepers. Who’s sleeping on the mattress impacts what level of support is needed. More sleepers means more space is needed. Factor in whether you’re going to have adults, kids, or a combination of both sleeping on the bed.

Sleep position has an impact on necessary cushioning and mattress thickness. Side sleepers, stomach sleepers, back sleepers, and combination sleepers all have different support needs. 

Budget is another important factor to take note of. What is your budget and how flexible are you willing to be? RV mattresses are available in a range of different price points. The larger your mattress is, typically the more it will cost you. The type of mattress you want has an impact on price. 


How do I keep my RV mattress from sliding?

There are several different ways to prevent your mattress from sliding. The first is to make sure you are using the right size mattress for your bed slot or space. Measure the space and your mattress to determine if the sizing lines up. 

If your mattress is the right size, you have a few different options for sliding prevention. You can place Velcro under your mattress to help secure it in place. Another option is to put rubber mats under your mattress. Carpet tape can be used if you’re in a pinch, but this is not a good long-term solution. You can purchase these items from an online retailer like Amazon. 

How can I make my camper mattress more comfortable?

You can adjust the firmness of your mattress to fit your personal preferences with a mattress topper. Mattress toppers improve the comfort and support levels of your existing mattress. This decreases the chances of you experiencing aches and pains. 

Is a single bed smaller than a twin?

Single beds and twin beds are the same bed. The alternative phrasing “single” is used to designate that a twin bed sleeps one person. A twin or single bed measures 38 inches by 75 inches. 

Should I get a 10-inch or 12-inch mattress?

The thickness of your mattress depends on your RV bed setup and support needs. If your RV sofa-bed is a slide-out configuration, it should only be between 5 and 6 inches thick. All other bed setups can fit any mattress thickness level.

A thicker mattress includes more comfort and support layers. Those who sleep on their back or stomach can get by with a mattress that is 10-inches thick. Side or combination sleepers need a mattress that is at least 12-inches thick. 

Body size and health conditions impact how thick of a mattress you need. Lightweight or heavy-weight individuals need a mattress that is at least 12 inches or thicker. Medium size sleepers will be comfortable with a mattress that is anywhere from 10 to 12-inches thick. Those with arthritis or back pain need a thicker mattress. 

Can you put regular furniture in an RV?

You can use regular furniture in an RV. The same couches, recliners, tables, and chairs that you have in your home can be put in your RV. However, the size of these items may need to be reduced. 

All RV furniture needs to follow a proper installation and anchoring process. This ensures your furniture does not slide while you’re driving. 


RV mattresses come in a wide range of sizes and dimensions. Finding the right size mattress for your RV is key for comfort and fit. The type of RV mattress you purchase influences the comfort, support, and cost. To better meet your comfort preferences, RV owners can add a mattress topper to their bed.
