RV Mattress Sizes - RV Pennywise

Is your RV mattress causing restless nights? Let's fix that ASAP. But before you buy a replacement, you'll want to understand the basics. A little bit of preparation will save you money and help you make a comfortable, lasting choice.

RV Mattress Size Chart

One consideration is your RV mattress size. Although some RVs get fitted with standard mattresses, most come in custom proportions. Length and width are two crucial measurements (see chart below).

But people often forget to consider mattress height.

The ceiling in a regular home's bedroom is well above the bed. Your body has plenty of space to sit up, roll side-to-side, or move about in your sleep.

In some RVs, however, clearance between the top of the mattress and the ceiling, storage cabinets, or upper bunk is much less. Therefore, the thickness (number of layers) of the mattress material, or the use of a mattress topper, makes a difference.

Depending on the configuration and style of bed in your RV, consider whether a few inches could affect your bedtime activities, asleep, or otherwise.

RV Mattress Size Definitions

RV Short Queen

As the name implies, this is a shorter version of the standard home bedroom Queen size. It's shorter for more efficient use of space, which is at a premium in RVs.

The Short Queen RV mattress size can comfortably accommodate two adults (who enjoy sleeping close together). Because it is the most popular sized mattress, accessories such as sheets and mattress toppers are readily available and relatively inexpensive.

RV King

The RV King mattress is both longer and wider than the Short Queen. It is the perfect size mattress for couples who prefer some sleeping room. And it's also a good choice for tall adults as you get an extra 5" legroom. Naturally, sheets, blankets, bedspreads or comforters, and even pillows are more expensive due to the larger RV King size.

RV Short King

The RV Short King is 5" inches shorter than the RV King but will still comfortably harbor two adults. Designed with a smaller RV floorplan in mind, it provides more walking room at the end of the bed.

Custom RV Mattresses

Many of today's RVs come with unusually shaped mattresses or sleeping areas. After all, every inch of space is valuable. For instance, you might notice rounded or cut corners (commonly referred to as radius, angled, or notched).

Custom RV mattresses are available from an exclusive category of manufacturers. In addition to creating custom shapes and sizes, they'll provide you with a choice of mattress material such as foam, foam latex, or memory foam.

Many manufacturers also offer custom-made accessories such as mattress toppers and linens.

How To Measure a Custom RV Mattress

To order the correct RV mattress size, you'll need to get out the tape measure and write down the dimensions of your existing mattress as well as the dimensions of the foundation on which it rests.

Measurements of the base the mattress sits on give you more accurate numbers. An RV mattress can shrink or expand due to things like temperature or humidity. And the interior material layers will shift and reshape with use.

Get the most accurate RV mattress size in three easy steps:

  1. Measure the base or foundation. Use the longest length and the widest width.
  2. Measure the dimensions of your existing mattress.
  3. Measure the height of your existing mattress. Take note of height considerations such as headroom for all bedtime activities, a low headboard or no headboard, and reach to the floor when getting in and out of bed.

If your mattress is an odd shape, talk with your chosen manufacturer. They may request a picture, drawing, or template. They may also provide a measuring kit to help you ensure accurate dimensions.

RV Mattress Sizes FAQs


First, the size (height, length, and width) is usually different. Often, a regular mattress won't fit properly in an RV. Sometimes, the shape varies too, and a custom build is needed.

Second, RV mattresses tend to be lighter. How much weight you're carrying - whether your rig is a motorhome, fifth wheel, or travel trailer - is an important factor in RVing for both economic and safety reasons.


To a large extent, the level of comfort you get from your RV mattress depends on its interior materials. Foam mattresses, for instance, are generally the lowest price and offer a basic level of comfort. But even foam can vary depending on the number of layers.

So if you're not looking to buy a replacement, a quick and easy solution is an RV mattress topper. They come in a range of materials, including foam latex, gel, and memory foam to act as a cushion for more support.

Another reason your RV mattress may not feel comfortable is due to its foundation or base. Many bed frames in RVs are plywood. It may leave you feeling a bit stiff in the morning. Plywood can also tear your mattress. A quick fix to this problem is to add a layer of foam (or similar material) to the base.


If standard sheets don't fit, your RV mattress is probably shorter than a regular one. Hence, they are loose and gather up beneath you in your sleep. It's a bother and can also affect your sleep quality.

One inexpensive solution is to use elastic sheet clips or straps. Another is to sew a shortened elastic hem to your existing sheets.


It varies significantly - there's no hard, fast rule. Be sure to rotate it every so often, just like you would a standard mattress. Use a mattress cover to protect its longevity. Wash the bedding frequently.

Signs that may indicate its time for an RV mattress replacement include:

  • Waking up with a sore back or neck
  • Tossing and turning throughout the night
  • Your mattress shows signs of sags, bumps, or other shifting and wear of the interior materials.

Choosing the Best RV Mattress

Before looking for a replacement mattress, first decide what type of material you prefer. Then measure your mattress and foundation.

Last, research RV mattress manufacturers to find the highest quality at the lowest cost. You'll want a lengthy trial period, free shipping, 10+ year warranty, and a no-hassles return policy.

Since RV mattress sizes vary depending on your vehicle or towable, you might also check with your RV manufacturer for recommended mattress providers.
