No Size Fits All!

RV mattress sizing can vary significantly compared to standard home mattresses. From narrow twin sizes to custom shapes, RVs often have limited space, requiring unique mattress dimensions. 

Understanding these differences is crucial to ensure a proper fit and maximize comfort during your mobile adventures.

RV Mattress Sizes

Generally, there are some overarching size metrics to follow when it comes to RV mattresses. While there may be variations depending on the specific RV manufacturer and model, there are several common sizes that are widely used in the industry. 

Here is a list of the most common RV mattress sizes:

RV Twin

This size is narrower than a standard twin mattress, usually measuring around 28 inches by 75-80 inches.

RV Full

Also known as a double mattress, it typically measures around 53-55 inches by 75 inches, providing a bit more space for single sleepers or cozy sleeping quarters for two.

RV Queen

A popular choice, this size measures approximately 60 inches by 80 inches, offering a comfortable sleep surface for couples or those who prefer extra space. There are typically two styles of RV Queen:

  1. RV Short Queen: 60 inches by 74/75 inches
  2. RV Queen: 60 inches by 80 inches

RV King

Though less common, some RVs have space for a king-size mattress. It provides ample room for couples who desire a larger sleeping area. The RV King mattresses really have 3 general sizing options:

  1. RV Short King: 72 inches by 75 inches
  2. RV King: 72 inches by 80 inches
  3. RV California King: 72 inches by 84 inches

RV Bunk

These mattresses are specially designed for bunk beds in RVs and often have varying dimensions depending on the specific bunk configuration. Listed below are the general bunk size options:

  1. 28 inches by 75 inches
  2. 30 inches by 75 inches
  3. 30 inches by 80 inches
  4. 34 inches by 75 inches
  5. 35 inches by 79 inches

Remember to measure your RV’s sleeping area carefully to ensure a proper fit. While these sizes are commonly used, it’s always best to verify the specific mattress dimensions recommended by your RV manufacturer or consult with a reputable RV mattress retailer to find the perfect fit for your mobile haven.

 RV Brand

The brand and model of your RV can have a significant impact on the type of mattress you can use. Some RVs come with specific mattress sizes and shapes designed to fit perfectly within the allotted space. An RV queen mattress that fits nicely and snug in an American Coach, while it might be the same “size”, would likely be the wrong size mattress for an Airstream or a Forrest River. While that would be fantastic, the RV designs are all just too unique.

Certain brands may have unique dimensions or unconventional bed configurations, making it necessary to seek custom or specialized mattresses. Additionally, some RV manufacturers offer proprietary mattress options tailored to their specific models. It’s essential to consider the brand of RV when selecting a new mattress to ensure compatibility and optimize comfort. 

Checking the manufacturer’s recommendations or consulting with RV experts can help you find the right mattress that perfectly suits your RV’s brand and model.

Taking matters into your own hands

To ensure a perfect fit for your RV mattress, always double-check your RV’s measurements, regardless of the sizes listed online. Avoid surprises and guarantee a comfortable sleep by being accurate and verifying the dimensions before making a purchase.

Certain RVs have unique configurations or unconventional sleeping areas that require custom-made mattresses. These specialized mattresses are tailored to fit the specific dimensions and shape of the RV, ensuring a perfect fit and maximum comfort. Custom mattresses are the ideal solution for RVs with non-standard sleeping arrangements.

Right size, but which type?

Now that you’ve figured out the size of your mattress, it’s time to explore popular RV mattress materials. 

Here are some of the most commonly used styles and materials:

Memory Foam

Memory foam RV mattresses are a popular choice due to their exceptional comfort and pressure-relieving properties. The viscoelastic foam contours your body, providing personalized support and reducing motion transfer. 

Its ability to conform to unique shapes and bounce back to its original form makes it a sought-after material for RV sleepers seeking optimal comfort.

Here are some of the benefits and downsides of choosing memory foam:


  1. Superior Comfort: Memory foam RV mattresses offer exceptional comfort by contouring your body shape, relieving pressure points, and providing personalized support for a restful sleep.
  2. Motion Isolation: Memory foam absorbs motion, reducing disturbances caused by a restless sleeping partner or movement within the RV, allowing for undisturbed sleep.
  3. Durability: High-quality memory foam mattresses are known for their durability, with the ability to maintain their shape and performance over time, making them a long-lasting investment for your RV.


  1. Heat Retention: Some memory foam mattresses can retain body heat, potentially causing discomfort for sleepers who tend to sleep hot. However, modern advancements in memory foam technology have addressed this issue with cooling features.
  2. Initial Odor: Memory foam mattresses may emit a temporary odor upon unboxing due to off-gassing. This odor usually dissipates within a few days and is harmless, but it may be a concern for individuals sensitive to smells.
  3. Cost: Compared to other mattress types, memory foam mattresses can be more expensive. While the initial investment may be higher, the comfort and durability provided by memory foam can offset the cost in the long run.

It’s important to consider personal preferences, sleeping habits, and budget when evaluating the pros and cons of memory foam RV mattresses to determine if it’s the right choice for your needs.


RV Latex mattresses are renowned for their natural and resilient material. Made from the sap of rubber trees, latex offers exceptional comfort and support. It provides a responsive and buoyant sleep surface, ensuring optimal spinal alignment. 

Latex is also hypoallergenic, resistant to dust mites, and offers enhanced breathability for a cooler and healthier sleep environment.


Innerspring RV mattresses feature a traditional coil construction, offering a classic and familiar sleep experience. The steel coil springs provide excellent support, durability, and bounce. With various coil systems available, such as pocketed coils or continuous coils, these mattresses deliver reliable comfort and proper spinal alignment for a rejuvenating night’s rest.


Air RV mattresses utilize air chambers as the primary support system, allowing sleepers to adjust the firmness level according to personal preferences. The inflatable nature of these mattresses makes them lightweight and easy to transport. They provide customizable comfort, making them a versatile choice for RV travelers seeking adjustable sleeping surfaces.

Where to buy RV mattresses

RV mattresses can be purchased from various sources. Online retailers offer convenience and a wide selection, while local RV dealerships or mattress stores may have in-store options. For custom mattresses, specialty RV mattress manufacturers can provide tailored solutions to meet specific needs.
