Custom RV Mattress Guide

Are you looking for a custom RV mattress? Or perhaps you are looking to replace your existing RV mattress with something better. The following guide is full of information that can help you find the best RV mattress for your needs.

Understanding Why a Regular Bed Mattress Won’t Work in Your RV

In almost all cases, RV mattress sizes are different from those in your home. They tend to be either shorter or longer in some cases than a standard queen or full-size mattress. 

It’s also common to have a corner of the mattress that is cut off at an angle, or rounded, which obviously isn’t something you see in a regular bedroom! 

The thickness or depth of RV mattresses tend to be lower than standard bedroom mattresses. The average thickness for a standard mattress in today’s world is around 12”, but it’s not unusual to see some over 15”. Due to the height of furniture pieces inside RVs, as well as the roof clearance, it’s more common to need 6”, 8” or 10” height to fit comfortably.

Where to buy RV mattresses?

RV mattresses aren’t typically sold at your local mattress store. Instead, you can find them at specialty stores like factory-direct companies, RV dealers, and online. The trouble that most people have is finding an RV mattress that is high-quality.

Benefits of an RV Mattress

You will find many benefits of an RV mattress over a conventional mattress. These benefits make RV mattresses the most popular choice for campers and travelers.

The following are some benefits of having an RV mattress:

  1. Supportive. An RV mattress needs to be supportive enough to support your body weight for long periods of time.
  2. Comfortable. RV mattresses should be comfortable enough for you to sleep on them for long periods at a time without developing back pain or other types of discomfort such as soreness from sitting in a chair all day.
  3. Durable. The mattress you place in your RV should be durable enough to last for years without developing holes or other forms of damage that would cause it to become unusable over time.
  4. Easy To Clean And Maintain. An RV mattress should be easy to clean and maintain so that you don't have any trouble keeping it looking clean and new even after years of regular use. One easy way to keep your RV mattress clean is by purchasing a Waterproof Mattress Protector. These can be placed right on the mattress and prevent moisture from entering it.

How To Choose The Best RV Mattress

Identify the Space

There are a couple of ways to measure for the correct size RV mattress. You’ll need a tape measure, the camera on your phone, and perhaps a helper in the event anything has to be moved:

  1. Measure the size of the platform that the mattress will be resting on.  You want to measure the full width, from one edge of the platform to the other, and then do the same for the length. If there are walls on one or more sides, measure as best as you can up to the point where the flat surface stops.  Once you have your “tight” width and length measurement, it’s a good idea to undersize by 1” and order your mattress that size. If you end up with a half-inch measurement, just round that down to the nearest whole inch. This ensures that the mattress will fit comfortably and leaves a tiny bit of room to tuck in sheets. The last step is to take a picture of the space where the mattress will go.  This can be helpful to the mattress builders and will give them an idea of how it will be used.
  2. Measure the width and length of the existing mattress.  Although mattress sizes and shapes can change over time, measuring the current mattress should give you the general size for the new mattress. In this case, you wouldn’t need to take an inch off the measurement because you know the mattress already fits unless you wanted to. Like in the first step, snap a picture of the current setup just in case the mattress guys need it.
Find Your Size

It's important to choose the right size when buying an RV mattress. This will depend on the size of your trailer or camper and how much space you have in it. RV mattresses come in different sizes: twin, full, queen, king and California king (which is longer). A queen-sized mattress fits most trailers and RVs and can accommodate two people comfortably; however, if you plan on having guests over often or sleeping with two people at once, a king-sized mattress might be better suited for your needs.

Select Your Mattress

RV mattresses come in a variety of materials and thicknesses. The type you choose depends on your preference, the size and weight of your RV, where you plan to store it, and how much you want to spend.

Selecting the right mattress for your RV can be a challenge because there are so many options available. Some mattresses are designed for temporary use, while others are built to last for years. If you're looking for a long-lasting mattress, here are some things to consider:

Material - Nylon, polyester or foam? Each material has its advantages and disadvantages. For instance, foam is durable but heavy; nylon is lightweight but prone to punctures; polyester combines durability with light weight.

Thickness - Thinner mattresses are easier to move around inside your RV and store when not in use. However, they may not be as comfortable as thicker models since they tend to sag over time due to their lower-density fillings. Some RV owners prefer thinner mattresses for this reason because they tend to be less expensive than thick ones.

Size and Weight Capacity - Larger mattresses typically have higher weight capacities than smaller ones because they're made from denser materials.

Best RV Mattresses

Best Overall

Custom Mattress Makers has a wide range of mattress designs, and they're all good. They're supportive, comfortable, and surprisingly affordable. Most of the mattress models are hybrid design, which means better support and airflow. Additionally, all of the mattress have a cooling gel infused into the surface fabric to keep you temperature neutral throughout the night.

Best Value

Our Mattresses offers high-quality mattresses at fair prices. Everyone deserves a good night's sleep, and we want to help you get it. Custom Mattress Makers helps people sleep better by providing the best value mattresses on the market. We offer a wide range of comfort options and high-quality materials used, which include memory foam and natural latex.

Best for Couples

Mattresses from Custom Mattress Makers are great for couples. The mattress is made from foam and latex, which provide the best support for your body. The mattress offers a medium firmness and is designed for people who sleep on their backs or sides. It also has a bounce to it, so if you have a partner that likes to move around in bed, this is the perfect option for you.

Best for Kids

Custom Mattress Makers mattresses are designed for kids of all ages. They come in many different colors and styles, so there is something for every child's taste. These mattresses are also very comfortable and supportive, which means your child will sleep well at night.

Custom Mattress Makers makes many different types of mattresses for children. They have crib mattresses that are ideal for infants, as well as twin-size mattresses that work well for older kids who need their own beds. The company even makes full-size mattresses for older children who want more space than a twin offers them.

Best for Cooling

Maintaining a neutral sleeping surface at night is definitely a plus. There are numerous products available that are advertised to keep your body from overheating at night. Since it can be tough to test the integrity of this, it may be smart to look at the material under the cover.  You want to make sure that there is as much airflow inside the mattress as possible, to keep heat from being absorbed with nowhere to go. This is one advantage to the hybrid mattress design mentioned earlier. The space between the coils is much larger and easier for air to pass through, versus all foam which tends to have a bit more difficulty breathing. 

In our Black Collection mattresses, special NanoCoils are added to increase airflow and breathability even more.


What size is an RV Mattress?

There are three sizes of RV mattresses: full, queen and king.  However, Custom Mattress Makers can make a wide variety of sizes that aren't common.

  • The standard for a full-size mattress is 54 inches wide by 75 inches long.
  • The queen-size mattress is 60 inches wide by 80 inches long.
  • And the king-size mattress is 76 inches wide by 80 inches long.

Do RVs need special mattresses?

Yes, RVs need special mattresses. It’s not just about the comfort of sleeping on a mattress that’s too soft or too hard. There are also safety concerns to consider when choosing RV mattresses.

RVs are designed for use on the road, but that doesn't mean you should skimp on your mattress. In fact, it's one of the most important parts of your RV. A good night's sleep is essential for staying safe, alert and comfortable while traveling.

What size is a Camper Mattress?

Camper mattresses are usually a standard size, but some are custom-made. Here are the most common sizes:

Standard - The standard size for camper mattresses is approximately 52 inches wide and 80 inches long. This size fits most pop-up campers with a queen-size mattress and many slide-in campers with a twin-size mattress.

Queen - A queen-size camper mattress is about 60 inches wide by 80 inches long. This size typically fits slide-in campers that have a queen-size bed or larger.

King - A king-size camper mattress has dimensions of approximately 76 inches wide by 80 inches long. This size works well in slide-in campers with king beds (or larger) and pop-ups designed for king beds.

RV Types

There are many different types of RVs to choose from, each with its own unique set of pros and cons. The following are the most common types:

  • Motorhomes
    These are typically large and heavy RVs that can hold up to eight people. They're equipped with bathrooms, kitchens and sleeping areas, making them great for family vacations or weekend getaways. Motorhomes are also known as Class A RVs (or simply A-Class), because they fall under the American National Standards Institute's classification system.
  • 5th wheels
    Fifth-wheel trailers are similar to travel trailers but bigger — their rear sections aren't designed to fold down when unhitched from a tow vehicle, so they tend to be heavier than other types of RVs (but still smaller than motorhomes).
  • Travel trailers
    These are small RVs with a fold-down rear section that allows them to be towed by a vehicle. They're great for those who want to take short trips without having to worry about hooking up their RV to a tow vehicle. Travel trailers come in all shapes and sizes, but most have basic amenities like beds and bathrooms, along with limited cooking options (typically just a stovetop).
  • Toy haulers
    Toy haulers are designed specifically for hauling RVs, boats, dirt bikes and other recreational equipment. They typically come equipped with ramps so vehicles can be loaded into the back of the trailer without having to lift them onto a hitch platform. Toy haulers are usually smaller than other types of RVs because they don't need to carry passengers or sleep six people at one time.
  • Pop-up campers
    Pop-up campers are one of the smallest types of RVs available today. They consist of an open space with sleeping areas above it, similar to tents but with more permanence and comfort. Pop-up trailers are very easy to set up once you find your campsite, which makes them ideal for people who like to do their own thing when they camp.
  • Truck campers
    Truck campers are also called fifth-wheel RVs. They're built on the frame of a pickup truck, but they have an extra section that makes them larger than a typical pickup truck. These units are generally bigger than motorhomes, but they don't have sleeping bunks like some motorhomes do.

Materials / Mattress Types

  • Hybrid
    This design would feature individually-wrapped coils in the support layer with upholstery padding above in the comfort layer. Hybrid mattresses are considered the most durable design with the least amount of change over time. You receive strength from the steel in the support system, while the top comfort layer padding gives you comfort.  The best of both worlds.  One downside to the hybrid design is it tends to be pricier than all foam, which is related to the cost and quality of materials used.
  • Memory Foam
    Memory foam is the most popular type of bedding for a good reason. It lasts longer than other mattress types, it's comfortable, and it's affordable.
    Memory foam mattresses are made with a layer of viscoelastic polymer gel that becomes less dense when pressure is applied. When you lie down on it, the material will mold to your body shape and support your body weight, providing pressure relief and support where it's needed most.
  • High-Density Foam
    One of the more common RV mattress designs is high-density foam.  This is poly-based padding that is widely used in just about every mattress today.  There can be several layers of padding to make up the mattress, from the support layer to the comfort or transition layer on top. Although it isn’t the “top-of-the-line” in terms of makeup, it is found in almost every new RV and has been a staple in the industry for decades.
  • Air
    Air mattresses are also good options for RVs because they don't take up much space when deflated and stored away during the off-season. This makes them ideal for people who only use their RVs occasionally or live in areas where they don't get much use out of their vehicles during the winter months when snow covers everything in sight!
    Air mattresses come in both twin and queen-size options, which makes them perfect for couples or families traveling together who don't want to crowd into one bed together!

The Cover

  • Quilted: This cover is typically a fabric textile that is quilted into a padding material. It provides a more “classic” mattress look and feel, one which may be more similar to your bed at home. The quilted padding may also provide additional comfort versus a non-quilted cover.
  • Smooth, Unquilted: Perhaps the more common design is simply a fabric material that is sewn into a cover with a zipper at the bottom.  There are many different types of material used for this, from cotton and polyester.

Mattress Features

Mattress features are extremely important to consider when buying a new bed, but there are so many options out there that it can be difficult to know what's best for you. Here are some of the most important features to look for when shopping for a new mattress:

Mattress Size: The first thing you should do when deciding on a mattress size is measure your current bed frame, and then compare it to your desired mattress size. If you have a queen-sized bed frame but want a king-sized mattress, you might have to make adjustments in your home or buy an entirely new bed frame.

Mattress Type: There are several different types of mattresses available on the market today. The most common types include traditional coil spring models, which tend to provide good support and durability at an affordable price point; foam mattresses, which offer comfort but little support; and hybrid models which combine different materials into one bedding solution (such as memory foam).

Mattress Brand: Mattress brands vary widely from manufacturer to manufacturer — some companies focus solely on one aspect of the bedding industry (like latex foam), while others create products across multiple categories (like Simmons). Some brands specialize in low-cost mattresses.

Mattress Thickness

Mattress thickness is one of the most important factors to consider when choosing a new mattress. The thickness of a mattress is an important consideration because it can affect comfort, support and durability.

Mattress thickness is measured in inches, with most mattresses being between 5 and 10 inches thick. Mattress thicknesses in this range are considered standard for most people, with some exceptions.

The thicker your mattress is, the more durable and supportive it will be over time. A thinner mattress may have a shorter lifespan than its thicker counterpart because it cannot provide as much support over time. Thicker mattresses also tend to be more comfortable because they have more surface space for your body to sink into.

Check the Reviews

When buying a mattress online, sight unseen, it’s definitely helpful to read what current owners have to say about their experience. However, it’s important to be critical in some cases and use these tips when browsing a website: 

  • Make sure that the reviews posted on a website are “Verified” by a third-party source.  What this means is that the person that wrote that review is actually a customer of the company and not a paid actor or robot. Although not all legitimate reviews are verified, it’s usually a good sign that the company is transparent. 
  • Look for pictures posted by the reviewer. This could perhaps be the best way to know reviews are in fact real. When the person adds a picture of their mattress. you know that they were motivated enough to take the time and share what they’re happy about!

Post-Purchase Advice

Here are some post-purchase tips to ensure you get the most out of your new mattress:

  1. Make sure the mattress fits the bed frame. If it doesn’t, you may feel like you’re rolling off the edge of your bed during the night, which isn’t very comfortable or safe.
  2. Don't skip on sheets and mattress protectors! Your new mattress needs to be protected from dirt and other elements that can wear down its quality over time.
  3. Never put a wet comforter on top of your mattress; it could damage its surface or cause mold growth if left in place for too long (even if it's clean). A better option would be putting your wet comforter in the dryer for 15 minutes on high heat before placing it back on top of your RV Mattress Cover.
  4. Cleaning isn't hard: Simply use a damp cloth and mild soap solution, then wipe away any dust or debris that might be collecting around the edges of your bed frame (note: do not use harsh chemicals).
