It only takes one night of restless sleep due to an uncomfortable mattress before you’ll want to replace it.

Unfortunately, no matter how much you spend on your rig, the mattress that comes with it will likely be terrible. To make matters worse, some manufacturers use cut-corner RV mattresses, which can be difficult to upgrade or replace.

Today, we’ll help you to find a way to replace or upgrade an uncomfortable cut-corner RV mattress. You’ll be sleeping like a baby before you know it! Let’s get started! 

What Is a Cut Corner RV Mattress?

A cut-corner RV mattress is a type of mattress with one or more corners cut off at an angle. Its unique shape maximizes the available sleeping space in an RV. While you have other areas you don’t want your manufacturer to cut corners, this is one area where it’s acceptable.

You’ll find cut-corner RV mattresses in various thicknesses, firmnesses, and materials. Just like a standard mattress, getting one that fits your space and provides the support and comfort you need is important. 

You need to get a solid night’s sleep while traveling to prepare for whatever adventures you have planned for the next day.

Is There a Difference Between an RV Mattress and a Standard Mattress?

RV and standard mattresses may appear similar, but they have differences. RV mattresses tend to be smaller than standard ones. For example, an RV queen is 60 inches wide and 75 inches long. However, a standard queen is 60 inches wide but 80 inches long.

These five inches may be important depending on your rig and if your bed is on a slide. You can’t always use a standard queen in every RV. If you replace your mattress, always check your measurements.

A few other differences include the thickness and materials. Manufacturers typically try to use lightweight products when constructing cut-corner RV mattresses. However, sometimes they push the limits and make them too thin, and they’re horribly uncomfortable.

Another important difference to mention is their costs. If you haven’t discovered by now, manufacturers typically charge a premium for any product that starts with “RV.” Mattresses are no different, and you can expect to pay a premium price for mattresses specifically designed with RVs in mind.

How Can You Cut Through Foam Mattresses Easily?

If you replace your cut-corner RV mattress with foam, you may need to cut it to fit. In those situations, it’s important that you do the job right, which means having the right tools for the job. 

Many DIYers will grab a serrated knife or sharp pair of scissors. However, this is incredibly difficult and typically provides less-than-ideal results.

To do the job right, you need an electric foam cutter. These tools aren’t expensive and can cut through foam like butter. The final results are a smooth and clean cut without jagged edges. 

This helps avoid mistakes and ensures a snug fit for your mattress. If having a polished look is important to you, don’t attempt to cut foam without this tool.

Ways to Replace or Upgrade Your Cut Corner RV Mattress

If you’re tired of waking up with a stiff or aching back, do something about it. Let’s look at how you can replace or upgrade your cut-corner RV mattress.

Foam Topper

Sometimes you don’t need to replace your mattress, but give it some help. A foam topper is a great way to accomplish this. These are great options because they come in various sizes and thicknesses. You can find firm, soft, or in-between foam toppers.

These can work as a budget-friendly way to help improve your ability to sleep in your RV. However, if you have a cut-corner RV mattress, you’ll likely need to cut it to fit. 

Invest in a foam cutter and take your time. As always, measure twice and cut once to avoid any errors.

Create Your Own From Foam

Sometimes when you want something done right, you’ve got to do it yourself. If that’s how you feel, you may need to create your own bed from foam. You can buy some from places like and make your own bed. 

Few people can say they built their own bed. But always measure carefully and have the right tools to cut it to size. 

Being off by an inch or two could be a costly mistake. Take your time when trimming, and you’ll likely have a fantastic finished product.

Custom Cut Corner RV Mattress

If you don’t like the idea of making your own cut-corner RV mattress, some companies will do it for you. TOCHTA and Mattress Insider are two of the most popular choices for this. 

Their online resources make it easy to input details specific to your bed to ensure a perfect fit. Ordering a custom cut-corner RV mattress doesn’t get any easier than this.

Take matters into your own hands and upgrade or replace that hunk of junk. You can sleep tight whether you choose a mattress topper, custom mattress, or make it yourself.
