The Ultimate Guide
to Buying a Replacement RV Mattress 2025

“ARRGHHHH!!! You have got to be kidding me!!” That’s probably what you said after calling several local mattress retailers who told you they don’t carry rv mattress sizes. Have no fear! There are several online retailers to choose from. This guide will equip you with the knowledge you need to shop for the perfect rv mattress. (feel free to skip ahead if you already know something!)

DETERMINE YOUR RV MATTRESS SIZE

The first step to buying a replacement RV mattress is to figure out what size you need to order. Most people will measure the mattress. You can do this if you’re in a hurry. However, the most accurate way to do it is to measure the dimensions of the surface the mattress rests on. Usually the mattress is placed on ply-wood or some type of similar surface. There are two reasons why this is more accurate. The first being that your rv mattress may not be the same size as it was when the RV was built. This can be due to fluctuations in temperature during off-season storage (especially you folks in Arizona!) or from exposure to UV light if the RV was kept uncovered during storage.

In addition, RV mattresses are made by both humans and machines. If you take 10 out of stock, you will get a slight variation in size.

If you measure the RV mattress instead of the surface it lies on, it may lead you to believe that you need a custom mattress size.

Don’t worry, measuring is easy! Just know that you’re lucky you’re not replacing a v berth mattress for a boat. (Those are a pain!)

The most common RV mattresses are in the shape of a rectangle.

It’s also possible that you might need one of the common “truck mattress” sizes if your replacing a mattress for a bunk in your RV.
The common truck mattress sizes are:

There are many other sizes available, but these are the most popular. Some of our products are offered in other sizes, such as family bed sizes.

Custom sizes include anything from odd rectangle sizes, to mattresses with cut or rounded corners (some airstream rv’s for example). Don’t worry though, custom sizes don’t have to be expensive if you find the right custom rv mattress supplier.

CHOOSE AN RV MATTRESS TYPE SIZE

What follows is a description of the 4 most common types of RV mattresses to help you narrow down your selection.

Foam RV Mattress

This is the most common RV mattress type because of the price point. If you only use your RV a few months out of the year, this is probably your best option. Price ranges for these generally range between $150-$350.
Standard foam RV mattresses are approximately 5-6 inches in thickness. The most important thing to consider is the density of the foam. Foam densities range between 1-2 lbs per cubic foot. The 1.8-2 lb densities tend to be more durable. They also can withstand more body weight and they tend to have less manufacturer defects.
Foams in the 1-1.5 lb category tend to break down quicker and they can’t withstand as much body weight over a long period of time. This density range also tends to develop ruts and depressions in the mattress leaving you feeling like you’re stuck in a ditch.
Another thing to ask is if the foam is 100% Petroleum based. Some suppliers offer soy based rv mattresses that are more eco-friendly.

Memory RV Mattress

This is the most common RV mattress type because of the price point. If you only use your RV a few months out of the year, this is probably your best option. Price ranges for these generally range between $150-$350.
Standard foam RV mattresses are approximately 5-6 inches in thickness. The most important thing to consider is the density of the foam. Foam densities range between 1-2 lbs per cubic foot.

Latex RV Mattress

Just like the memory foam rv mattress, the latex rv mattress is an excellent choice for those who spend a lot of time in their RV or who wish to have something very comfortable. It’s also perfect if your looking for the most eco-friendly rv mattress available. They generally range in price between $599-$999.
Latex rv mattresses are usually constructed so that the top layer is latex and the bottom support layer is urethane foam. Unlike memory foam and urethane foam rv mattresses, latex rv mattresses don’t measure using density. The most important thing to ask is if the latex being used is natural, synthetic, or a blend. Obviously, if you are going to pay the price for latex, you want to make sure it’s natural. Synthetic latex and blended latex tends to break down and discolor when exposed to heat and UV light.
Natural latex is collected from rubber trees just like maple syrup comes from maple trees. It’s naturally hypo-allergenic, dust-mite resistant, and anti-bacterial. If your someone who has latex allergies, for obvious reasons, we suggest not purchasing a latex rv mattress.
Another thing to ask is if the foam is 100% Petroleum based. Some suppliers offer soy based rv mattresses that are more eco-friendly.

RV Air Mattress

This is another high end option for your RV. The prices range between $1100-2000.
RV Air mattresses use the same concept as your blow up mattress you pull out for your guests except it’s taken to the extreme. The idea is that by using 2 air chambers, you can adjust the firmness of each side of your mattress. This is appealing for two people who have different comfort preferences. Layers of urethane, memory foam, or latex are put on top of the mattress and act as comfort layers.
Generally, we don’t recommend purchasing an RV Air mattress for a few reasons. The biggest problem is with air leakage. There is nothing more irritating then setting your optimal air pressure only to wake up at 3am to a deflated or saggy mattress. We get calls all the time from people who have this issue. When you call the manufacturer for service, you discover that it’s too costly and time consuming to have it repaired. Usually you’re the one who gets to do the repairing. Generally the assembly (it usually arrives in 3 boxes full of parts) can be difficult, especially for those who are disabled or elderly. Recently there was a class action lawsuit between a major airbed manufacturer (who will remain nameless) and it’s customers surrounding a problem with mold developing between the foam comfort layers and the air chambers. Supposedly, the manufacturer has developed a foam that is resistant to mold, but it’s still in the infant stages.

THE MOST IMPORTANT THINGS TO DISCUSS WITH ANY RV MATTRESS SUPPLIER (BEFORE YOU BUY)

The Return Policy Scam What happens if you don’t like it? Can you return it? Unfortunately…99% of rv mattress return policies are completely useless and I’ll tell you why. Most RV mattresses come compressed and rolled in the factory so that they can be shipped via UPS/Fedex. This avoids the oversize charges. The mattress arrives looking like a piece of rolled up carpet (about 1″ in thickness) and it expands out to anywhere between 5-8 inches in thickness once it’s opened. Once you unpack it, despite what any mattress salesman tells you, it’s IMPOSSIBLE to get them back into that box. To return it, you’ll end up needing to buy a flat pack mattress box (approx $40 including shipping) and you’ll need to use a freight carrier (as it’s now too big to be shipped UPS or Fedex). Generally freight charges range between $300-$800 for a typical queen rv mattress. Upon discovering this, you’ll find it’s more cost effective to just keep the mattress. Fortunately, MattressInsider.com has found a way to offer a 365 day money back guarantee and to get around this issue.

Part 1

Within the first 30 days, if you don’t like it, you can donate it to any non-for-profit (church, charity, etc), fax us a copy of the receipt, and you’ll get a no questions asked 100% refund.rong>

Part 2

After the first 30 days, if you still decide you don’t wish to keep it, we’ll help you get a custom made mattress bag that will enable you to use an ordinary vacuum cleaner to recompress your mattress. This gives you the ability to ship via UPS/Fedex and avoid using a freight carrier.
Details about this policy can be found on the product pages.
Density Scam
Unfortunately, any retailer can lie about the density of their product and get away with it. The only way to determine the density of your mattress on your own is to cut out a cubic foot block and put it on a scale. As I’m sure you can guess, no one is going to destroy their mattress just to verify the density. There is an online retailer based in California that claims to sell a 5.3 lb density memory foam rv mattress. Upon careful inspection we discovered that the foam was actually only 2.5 lbs. Make sure you go for an RV mattress supplier you can trust. Ask lots of questions and do your best to make sure you get straight answers. We suggest typing the name of the supplier into Google with the word “complaint” after their company name. If you find lots of complaints about that retailer, obviously, you’ll want to stay away from them.
