RV Mattress Sizes: Dimensions + Chart

What are RV mattress sizes? 

RV mattresses are typically shorter in length and thinner than standard mattresses. Sizes range from RV bunk or twin mattresses measuring 28-by-75 inches to RV California king mattresses measuring 72-by-84 inches.

You shouldn’t have to sacrifice restful sleep while on the road. Finding the perfect RV mattress can ensure you can fully enjoy your travels without losing sleep.

With a variety of mattress sizes and types, the world of RV mattresses can be a bit confusing. RV mattress sizes differ from traditional sizes, but we’ve done the research so you don’t have to.

In this guide, we’ll show you how to choose a mattress for your RV or camper needs. We’ll also cover the types of RV mattresses available, what sets RV mattresses apart from standard mattresses, and whether you should invest in a custom-made travel mattress.

Though they aren’t available in specialty RV sizes, Purple mattresses are the best option for pressure relief, cooling, and adaptive support.

Disclaimer: Purple mattresses feature Purple’s proprietary GelFlex Grid®, which offers unique pressure relief and support. Exposure to prolonged high-temperature environments or direct sunlight — conditions that are common in RV and campers — can lead to a loss in support from the GelFlex Grid®.

While many RVs and campers can accommodate standard size mattresses or be modified to do so, this guide covers the sizes that can comfortably fit into RVs.

RV mattresses may have the same names as their counterparts at home, but they often differ in their measurements.

Wondering what size mattress will fit best in your RV? Here’s a quick guide to common RV mattress sizes, their dimensions, and who may sleep comfortably on them:

RV Mattress Sizes

Below, we’ll explore the differences between RV or camper mattress sizes to give you a better idea of what’s available.

RV Twin Mattress

RV twin size mattress dimensions: 28-by-75 inches or 28-by-80 inches

Compared to standard twin size mattresses, RV twins are 10 inches narrower and come in two lengths — the same lengths as a twin or twin XL bed, respectively. These mattresses are very common in RV setups, given their narrow width and ease of fitting into tight spaces. They're also perfect for bunk beds. You can usually find RV twin mattresses in two different sizes to accommodate different sleeper heights. 

Twin Mattresses

Twin size mattress dimensions: 38-by-75 inches

Depending on the type of mattress and how thick it is, some standard twin beds can comfortably fit in an RV. Perfect for kids or adults under 5’9”, a standard twin bed may be worth considering for your RV or camper, especially if you don’t want to get a custom mattress made.

RV Bunk Mattresses

RV bunk size mattress dimensions: 

• 28-by-75 inches
• 30-by-75 inches
• 30-by-80 inches
• 34-by-75 inches
• 35-by-79 inches

If you’re looking for a family-friendly setup with lots of sleep space for the whole family, bunk RV mattresses are an excellent choice. They come in a wide range of mattress sizes and dimensions to fit many sleepers’ ages and sizes.

RV Truck Mattress

RV truck size mattress dimensions:

• 35 to 42 inches wide
• 79 to 80 inches long

The truck size mattress gets its name because people often place it inside the cab of a semi-truck, but you can also use it in an RV. Truck mattresses measure between 35 and 42 inches wide by 79 or 80 inches long. If you’re a tall sleeper, a truck size mattress is an excellent option.

Three-Quarter Mattress

Three-quarter size mattress dimensions: 48-by-75 inches

The three-quarter mattress is a little smaller than a standard full size mattress but slightly larger than twin and bunk RV mattresses. This is a good choice if your RV doesn’t have room for a full size mattress. A three-quarter mattress usually measures 48-by-75 inches and can comfortably sleep two children or one adult.

RV Full Mattress

RV full size mattress dimensions: 53-by-75 inches

While they share a name, RV full or double mattresses are actually an inch narrower than the full size mattress you’re used to sleeping on. This is usually the standard kind of mattress that comes with an RV when you first purchase it.

Full or Double Mattress

Full size mattress dimensions: 54-by-75 inches

In most cases, a standard full bed won’t fit inside an RV. Full beds may not be a large enough mattress size for couples, but teenagers and single adults under 5’9” often find them roomy.

Full size mattresses from Purple’s Essential Collection are a great fit for campers and RVs, measuring between 8 and 11 inches thick. With flexible Comfort Foam and our proprietary GelFlex Grid®, these mattresses offer simple soothing comfort, temperature-balancing, and pressure relief for a great night’s sleep no matter where you are.

RV Queen Mattress

Short queen size mattress dimensions: 60-by-75 inches

Also referred to as a short queen mattress, this mattress differs from the queen size mattress you’re used to at home, measuring five inches shorter. With this kind of bed, two adult sleepers can fit fairly comfortably. 

While we don’t carry short queen sizes, Purple’s queen size mattresses offer enough space for two sleepers with cushioning pressure relief and adaptive support. Opt for a mattress from the Essential or Restore® Hybrid lines with mattresses under 13 inches tall for the best fit in your camper or RV.

Short King Mattress

Short king size mattress dimensions: 72-by-75 inches

A short king mattress is four inches narrower and five inches shorter than the king size mattresses designed for bedrooms. RV king mattresses offer enough room for two sleepers without taking up as much space as a standard king.

RV King Mattress

RV king size mattress dimensions: 72-by-80 inches

Though four inches narrower than a standard king, RV king mattresses are large enough to comfortably accommodate up to two adults and a co-sleeping child. Because of their generous space, RV kings are a good choice for large campers used by traveling families. 

Some mattress companies use the terms “RV short king size” and “RV king size” interchangeably, so check the company’s official measurements to confirm which size you’re really getting.

If you’re looking for a king size camper bed, Purple king mattresses are a great fit for wider RVs and traveling families who co-sleep with kids. Make sure you choose a flexible mattress that isn’t too thick; options like the Purple Plus® Mattress or the Restore® Hybrid Mattress in a king size are worth considering!

RV California King Mattress

RV California king size mattress dimensions: 72-by-84 inches

RV California king mattresses have the same width and length as the standard California king bed size, making them longer than their RV king size counterparts. These RV mattresses tend to be thinner than standard beds in order to fit inside the confined space of an RV or camper. Sleepers over  six feet tall will appreciate the extra legroom that keeps them from feeling cramped.

A California king mattress from Purple offers ample comfort with adaptive pressure relief and full-body support thanks to the GelFlex Grid®. Opt for a mattress from the Essential collection for maximum flexibility in your camper or RV.

Types of RV Mattresses

RV mattresses are more compact with fewer layers than standard bedroom mattresses, so your options for comfort, support, and special features may be limited. If you’re shopping for RV mattresses, you can often choose from the following types:

• GelFlex Grid®: Flexible and durable, GelFlex Grid® mattresses are completely unique, offering the perfect blend of temperature-balancing comfort and adaptive support.
• Innerspring: Classic innerspring mattresses may be more affordable, but they can also wear out faster, requiring more frequent maintenance or replacements.
• Memory foam: Foam beds can provide pressure point relief, but they can also trap heat, resulting in overnight discomfort while you travel.
• Hybrid: Hybrid mattresses are fairly uncommon for RVs but can provide a better balance of structured support and comfort at a higher price tag.
• Air: Air mattresses are inexpensive, convenient options, but they tend to be the least durable mattress type.
• Collapsible: Hinged mattresses or cots provide an easy sleeping solution at the cost of comfort.

In the market for a new mattress? Invest in your sleep quality with a Purple mattress. The GelFlex Grid® in every model cradles your pressure points, dissipates body heat, and provides support for your entire body so you can sleep soundly night after night. For even greater comfort on the go, consider pairing your mattress with a the Purple Harmony Anywhere™ travel pillow, designed to deliver the same pressure-relieving support wherever you rest.

When replacing or upgrading the mattress in your RV or camper, it's important to consider several key factors to ensure safety, comfort, and compatibility. RV or camper mattresses often come in non-standard sizes and shapes, so accurate measurements are essential before purchasing a replacement.

Additionally, mattress weight can vary significantly between models and materials; adding a heavier mattress may impact your RV or camper’s weight distribution, cargo capacity, and slide-out mechanisms.

Always check your RV or camper’s weight ratings and manufacturer guidelines before installation of a new mattress. If in doubt, consult a professional to ensure the upgrade does not compromise your vehicle’s structural integrity or performance.

Should You Buy an RV Mattress?

Getting a specialized RV mattress can be a worthwhile investment if you’re limited on space and want to ensure a good fit. In many cases, opting for a custom RV mattress can mean spending more on a mattress with fewer comfort features.

Ultimately, you should always choose the best mattress for your specific needs, preferences, and budget. 

For the perfect balance of cooling, pressure relief, and responsive support, Purple mattresses are a great choice. With thinner options from the Essentials line, flexible GelFlex Grid® mattresses in smaller standard sizes can keep you comfortable on the road.
