Why do RV mattress sizes matter so much?

When you buy a recreational vehicle (RV), you'll often find it fitted with a traditional type of mattress. It tends to be thin, hard, and often uncomfortable for those of us who prefer something else. In this case, a new mattress must be brought in to take its place. However, without proper knowledge of the size of the mattress you seek, you may buy one that doesn't fit the allotted space in your RV.

The problems do not end with size-unsuitability either. The wrong-sized mattress can result in sleepless nights due to uncomfortable sleeping positions, eventually leading to pain, aches, and distress in the morning. This can be dangerous, especially for the driver, who will have to drive the RV while feeling agitated and drowsy.

In order to avoid such issues, therefore, one must be aware of the RV mattress sizes that suitably conform to their RVs.

What are the different RV mattress sizes?

RV mattress sizes range from RV Twin (28” x 75”) to RV California King (72” x 84”). In contrast to regular mattresses, which come in standard sizes, RV mattresses come in more compact sizes to fit the limited space available in an RV.

Below is a table that covers all the RV mattress sizes, their dimensions, and the types of RVs that they fit in best -

Now that you're familiar with the dimensions of the 11 RV mattress sizes, let's take an in-depth look at each one to give you a better idea of what they represent -

  1. RV Twin Mattress

Coming in at 28 inches in width and 75-80 inches in length, the RV twin-size mattress is the smallest of the bunch. It is suitable for compact travel trailers and RVs.

RV twin mattresses are budget-friendly and can fit narrow spaces, but they can only accommodate one person at a time. They're best used as a single bed for solo travelers.

  1. RV Truck Mattress

An RV truck-size mattress has many dimensions, ranging from 35-42 inches in width and 79-80 inches in length.

RV truck mattress sizes can be accommodated in truck campers, compact travel trailers, and compact RVs. They're best used for solo travelers or couples who don't mind sleeping close together.

  1. RV Bunk Mattress

RV bunk mattress sizes typically measure 28-35 inches in width and 75-80 inches in length. They are designed to fit family-friendly RVs with bunk beds and travel trailers with bunkhouse floor plans.

RV bunk mattresses are best used for families with children or groups of travelers who need to maximize sleeping space in their RV.

  1. RV Three Quarter Mattress

An RV three-quarter mattress size is 48 inches in width and 75-80 inches in length. It is also known as the "antique mattress size" due to its widespread historical presence in the 18th century.

RV three-quarter mattresses fit nicely in RVs where the full-size won't fit, and the twin/truck size won't suffice. They can comfortably accommodate either a single adult or two kids.

  1. RV Full Mattress

A full-size RV mattress is 53 inches wide and 75 inches long. It is perfect for single adults to stretch out and obtain a spacious enough surface to sleep on. Thin couples who are willing to compromise on space may also find it useful.

Full-size RV mattresses are suitable for mid-sized RVs, travel trailers, and fifth-wheel trailers.

  1. RV Short Queen Mattress

The RV short queen mattress is slightly shorter than the RV queen mattress, with a 60-inch width and 75-inch length. It is a bit more spacious for couples than a full-size RV mattress and can accommodate up to three children.

RV short queen mattresses are most suitable for larger RVs, travel trailers, and fifth-wheel trailers.

  1. RV Queen Mattress

The RV queen mattress size is 5 inches longer than the short queen version, with a width of 60 inches and a length of 80 inches. These dimensions are also akin to those of a standard queen mattress.

Tall individuals, as well as couples, will find this size to be ideal for their needs. It can easily slot into RVs with plenty of room.

  1. RV Short King Mattress

An RV short king mattress is 72 inches wide and 75 inches long and calls for lots of space. RVs with a king-size bed slide-out, fifth-wheel trailers, and large travel trailers can accommodate it well.

The RV short king's extra width over the RV queen enables it to accommodate four children, a couple and a dog, or a family with a young child.

  1. RV King Mattress

RV king-size mattresses measure 72 inches in width and 80 inches in length, making them 4 inches narrower than standard king mattresses. Their target audience frequently consists of families with two children, allowing the entire family to snuggle up in one bed. An RV king-size mattress will require a luxury RV to accommodate.

  1. Eastern King Mattress

The Eastern king-size mattress is 4 inches wider than the RV king, with a dimension of 76 inches in width and 80 inches in length. This dimension matches that of a standard king mattress, making it perfect for families with kids and pets. It requires large RVs with an expanded or expandable bedroom.

  1. RV California King Mattress

The RV California king mattress is 4 inches longer than the regular RV king, with a width of 72 inches and a length of 84 inches. Though it is not as wide as a standard king-size mattress, it is still ideal for families with kids and taller adults who require the additional length. RV California king mattresses will require large and long RVs for installation.

How can you identify what size mattress fits your RV?

Different types of campers, RVs, and travel trailers

You're well-versed in RV mattress sizes, but that knowledge is useless if you don't know the measurements of your own RV mattress dimensions. Here's how you can go about measuring a mattress in an RV -

Step 1 - First off, check if the RV manufacturers have provided you with the specs of your RV, as they may contain the size of your RV mattress.

Step 2 - Obtain a measuring tape, measure the length, width, and thickness of your current RV mattress, then remove it.

Step 3 - Now measure the length, width, and depth of the area where the mattress sits.

Step 4 - If step 1 is a success, then compare and verify your measurements with the information on the specs sheet/size chart of the manufacturer.

Step 5 - Hit up stores that sell RV beds near you. See what mattress sizes and types fit your camper best. Then go shopping online and see if you can get a better deal.

One additional aspect you may need to note includes the corners, curves, and angles of your RV bedroom, as they may affect the type of mattress you can fit into it.

Note: Make sure to properly measure the thickness of your old RV mattress and the depth of the area where it sits. RVs tend to have limited vertical space, so a mattress that is too thick may not fit or may cause clearance issues.

What are the different types of RV mattresses?

Memory foam, latex, innersprings, hybrids, and airbeds are the most common types of RV mattresses on the market today. Each is unique in its own right, so knowing what to choose is important -

  • Memory Foam Mattress

Memory foam mattresses are synthetically manufactured using polyurethane foam and provide a heightened sense of pressure relief to sleepers. They conform to body contours very well, making for a comfortable, albeit hot, night's sleep. Memory foam tends to retain heat, and sleeping hot is usually never fun. A gel memory foam mattress is better able to offset the heating issues of traditional memory foam.

  • Latex Mattress

Latex mattresses are synthetic as well as natural. Natural latex mattresses contain organically procured liquid rubber converted to foam. They're superior to synthetic/blended latex mattresses and provide a balance between pressure relief and support. They're most well known for their extended durability, bouncy responsiveness, breathable cooling, and eco-friendliness. A study conducted in 2017 has even shown that latex mattresses excel over foam mattresses.

  • Innerspring Mattress

Innerspring mattresses make use of spring coils for support and additional firmness. The coils, which are often Bonnell, offset, or pocketed, are wrapped in a thin layer of cushioning material for comfort. Innersprings are bouncy, breathable, firm, and supportive. They tend to lack pressure-relieving and motion-isolating properties, however.

  • Hybrid Mattress

Hybrid mattresses also use spring coils as the core material but focus more on pressure relief by adding a thicker foam comfort layer. They're often of higher quality than innersprings, making them more expensive. You get a medium-firm feel from most hybrids, where the springs provide support and bounce, and the foam provides contouring and pressure relief.

  • Air Mattress

Air mattresses can be inflated and deflated on a whim, making them ideal for portability and customization. You can adjust their firmness to your liking by adding or removing air. However, they do not compare to traditional mattresses in terms of longevity, comfort, or support. It's best to prefer air mattresses if you need a temporary bed or a portable option for travel.
