Sometimes, it’s the struggles we remember most. Waking up with a stiff neck on the first day of vacation? Yeah, we’ve been there, and it’s no fun. That’s precisely why having a quality mattress in your RV bedroom is the foundation of a satisfying getaway.

Replacing your old RV mattress with a quality corner cut RV mattress is definitely worth your while. Still, there are plenty of types of mattresses to choose from, with plenty more decisions to make along the way. For your own sake, here are our best tips and tricks to take the guesswork out of buying a cut-corner RV mattress.

Consider the Old RV Mattress First

Getting a fresh, new replacement mattress is an exciting venture. Inherently, it means getting rid of your old one, which is a bit of a process.

As sizeable as your coach may be, any motorhome, 5th wheel, travel trailer, truck camper or pop-up camper has limited space. Still, RV manufacturers manage to fit a generously sized mattress in vehicles. They do this by building the RV around the bed.

But now you are either buying a used RV or it’s just time to replace your old RV mattress with a new one. It’s not easy to replace a corner cut mattress and you can’t buy one on Amazon – yet. Whatever the case, explore your options. A good night’s rest in your beloved RV is undoubtedly worth it.

Weighing Your RV Mattress Options

Luckily for you, there’s no shortage of RV mattress options for you to choose from. However, it’s not as straightforward as driving to the local mattress shop and taking your pick. This is especially so when your RV calls for a mattress with a cut corner.

Residential mattress dimensions vary from RV mattress dimensions. For example, you buy a queen-size mattress at the mattress shop. It’s probably not going to match the queen-size mattress in your RV.

Should your RV’s mattress have a right or left cut corner, the buying process becomes even more strategic. RV manufacturers cut off mattress corners to make the best use of space. It accommodates shelving, doors and other details of your floor plan. You’ll need to find a mattress whose measurements match the original exactly.

Our best advice? Take your time and shop around. See if there are any RV part stores in your area, if for no other reason than to get leads from a salesperson. Buying one online (at no extra cost for its cut-corner shape) will likely be your best bet.

The RV Mattress Size Guide

Unfortunately, there is no set standard for RV mattress sizes like there is for at-home mattresses. You’ll have to refer to your owner’s manual for exact details. While not precise, you can see if any of these three common sizes fit the bill:

RV Short Queen – 60″ x 74/75″
Three Quarter Size – 48″ x 75″
RV King – 72″ x 75/80″

How to Measure an RV Mattress and Platform

guide to measure cut corner RV mattressAs you may have figured out by now, measuring your RV mattress and the platform it rests on is a must. It’s really the only way you’re going to get a form-fitting mattress within your camper. So do yourself a favor, and measure twice, buy once.

Measuring your mattress space is not complicated by any means. There are two key steps you need to take when doing so.

First, measure the platform that the bed rests on. This is the maximum amount of space you’ll be able to fit a mattress on, but you don’t want to push your limits. At the end of the day, you won’t always be able to just trim your mattress down to size. It’s best to have some wiggle room.
Second, measure the empty space between the confines of your RV and the mattress itself. This measurement will tell you just how much wiggle room you really have in your buying journey. For RV mattresses with a cut corner, you may have one extra side to measure.

Cut-corner RV mattresses have five sides. When measuring, take down the numbers for the width and the length. Then, place the location of the cut corner. Measure the sides leading up to it individually, as well as the cut side itself. Be sure to note which corner is cut (right or left), so you buy a mattress that fits appropriately.

Mattress Materials and Their Pros and Cons

If we know one thing for sure, it’s that not all mattresses are created equal. It’s up to you to decide which material you want to rest your head on after a long day of adventuring. They all have their pros and cons, and it really depends on your personal wants and needs.

Go for Foam

If you’re on a budget, a foam mattress may be your best bet. Plus you can trim the mattress yourself to cut the corner off if you need to. They typically range from $100 to $400. Not only that, but they’re easy to alter should you need to change their shape or size a smidge.

Keep in mind that foam is crafted entirely from petroleum. You have to take certain precautions to prevent mildew build up. An air circulation liner will solve any problems before they arise.

A Good Memory

Gel Memory Foam is a very popular RV mattress material. While it can be slightly pricier than basic foam, it’s not exactly out of the budget-friendly ballpark. You can find a quality one for anywhere from $400 to $800.

The same precautions for mildew prevention apply here. Get yourself a good mattress protector too to help protect your investment.

Air Mattress, RV Style

As RV connoisseurs know, air mattresses can actually be comfortable. If you only dip into the RV world on occasion, a basic air mattress may be enough. If you frequent your recreational ride, try an adjustable air mattress. They typically cost upwards of $1000.

If you go for an air mattress, there’s one thing you’ll want to keep in mind. You’ll need to adjust its pressure as you change altitude, which is a common occurrence for many an outdoor adventurer.

Custom Corner Cut RV Mattresses 

It’s hard to find an RV mattress with a cut corner. The Eco Mattress Store makes custom sized RV mattresses with an easy to follow guide for measuring exactly what you need. It’s a little more pricey but it’s a great option for a perfect fit.

What About RV Mattress Toppers?

Maybe you can’t get a super high-end RV mattress with a cut corner, but we know a secret. Add a mattress topper into the mix for a seriously comfortable night’s sleep.

Typically made from foam, or memory foam, mattress toppers are a fantastic fix for your moving bedroom. They can also serve as a temporary solution while you hunt for the perfect cut-corner mattress. We have a mattress topper on our short queen mattress, and it is incredibly comfortable.

Don’t be afraid to try mattress toppers in your cherished RV. After weekends away in whatever destination calls to you, we have a feeling your back will thank you.

Short Queen Sheet Set RVBloggerShort Queen Sheets and Comforters

In our experience, a mattress is only as comfortable as the sheets on top of it. Dressing a quality RV mattress in basic sheets is almost like giving up. Luckily, there are plenty of options to keep you cozy on your weekends away.

Getting sheets for your coach’s bed means having to deal with the same Queen Happy Camper Comforter RVBloggermeasurement issues as a mattress. RV Mattresses are usually shorter than their in-home counterparts. It’s important to find a set that fits your mattress just right. That’s why we have a short queen sheet set. It fits perfectly so our sheets aren’t slipping and sliding all over the place. And a camping themed comforter can make your RV feel nice and homey.
