Introduction to RV King Mattress

Recreational vehicles (RVs) provide a convenient and comfortable way to travel while bringing many comforts of home along for the ride. One of the key elements of any RV that impacts comfort and quality sleep is the RV king mattress.

An RV king mattress refers to a king-sized mattress designed specifically to fit RV beds. These mattresses differ from standard residential king sizes in a few important ways:

  • Dimensions – RV king mattresses are usually around 72” x 75” to fit the unique shapes and sizes of RV bedroom spaces.
  • Materials – They are made of durable, supportive materials that can handle the motion and humidity inherent in RV environments.
  • Weight – RV mattresses are lighter than residential ones to reduce wear on RV suspension and improve gas mileage.
  • Design – Special design considerations like zippered covers, foam encasement, and tri-zone coils provide support, longevity, and ease of replacement.

Opting for a high-quality RV king mattress brings benefits over other mattress sizes:

  • Maximized Sleep Space – Allows couples to sleep comfortably without feeling cramped.
  • Spinal Alignment – Provides excellent support for back and neck health.
  • Durability – Made to last for years of continuous weekend and extended trips.
  • Custom Options – Many brands offer RV-specific sizes, features, and customizations.

Finding the Best RV King Size Mattress: Reviews and Buyer’s Guide

As RVs become homes-away-from-home, travelers seek out the same comforts they have at home – like a supportive, comfortable bed. The right RV king mattress makes all the difference in getting truly restful sleep while on the road.

With more brands catering specifically to the RV lifestyle, there are many factors savvy RV owners consider when choosing a new RV king mattress.

What to Consider When Buying an RV King Mattress

Mattress Type

The materials and construction of the mattress impact everything from support and comfort to durability, weight, and price. Common types include:

  • Memory Foam – Conforms closely to the body to relieve pressure points. Retains some heat.
  • Latex – Provides cushioning and bounce while sleeping cool. Naturally antimicrobial.
  • Innerspring – The coil system offers a supportive structure. Many have foam or other cushion layers.
  • Hybrid – Combines foam comfort layers with an innerspring support core.

Firmness Level

The right firmness range helps keep the spine properly aligned while cushioning the shoulders, hips, and other pressure points.

RV king mattresses are available in soft to ultra-firm comfort choices, but medium to medium-firm tend to accommodate the widest range of sleepers.

Adjustable air mattresses allow customization of firmness.

Durability and Longevity

An RV king mattress needs to stand up to years of continuous weekend trips, long vacations, humidity, motion, and other environmental factors unique to life on the road.

Higher quality materials and protective treatments like waterproofing increase lifespan.

Weight and Dimensions

RV king mattresses measure about 72” long by 75” wide. Height ranges from 8” to 16”.

Lighter mattresses weighing 60-100 pounds reduce wear on the RV suspension system and improve gas mileage. Make sure yours will fit the particular bed frame in your RV model.

Pressure Relief and Spinal Alignment

An RV’s confined sleeping space can magnify pressure points on the shoulders, hips, and back. Contouring memory foam or latex provides the most pressure relief.

Zoned innerspring coils or firm edges provide spinal support while conforming foam cradles the body. This helps keep the spine in proper alignment.

Motion Isolation

If sharing the bed with a partner, a mattress that absorbs movement on one side so the other person isn’t disturbed is key for better sleep.

Memory foam and hybrid RV king mattresses provide superior motion isolation over basic innerspring models.

Temperature Regulation and Cooling

Some foam and latex trap heat but brands now infuse phase change materials, gels, graphite, or copper to help regulate temperature. Breathable covers and coil support cores also encourage airflow.

Adjustable air beds allow customization of firmness and provide inherent airflow and cooling.

Warranty Coverage

Look for at least 8-10 years of coverage against sagging, materials defects, and loss of shape or support. Rotating the mattress helps prevent impressions and uneven wear, as advised by manufacturers.

RV King Mattress Types Compared

Now that you know what specifications to look for in an RV king mattress, it’s helpful to understand the hallmarks of each major category.

We’ll compare the features, pros, and cons of the four most common RV king mattress types:

  • Memory Foam
  • Latex
  • Innerspring
  • Hybrid

So you can determine the right comfort, support, and convenience features for your RV model and sleep preferences.

Important Features to Consider in an RV King Mattress

While individual preference plays a big role in choosing an RV king mattress, prioritizing a few key features helps narrow options to find your ideal model more quickly.

Firmness Level for RV King Mattresses

Choosing appropriate firmness prevents discomfort and optimizes support for your body type and sleep position.

Side sleepers need more pressure relief while back and stomach sleepers require enhanced support. Heavier individuals require a firmer feel as well.

Firmness Recommendations by Sleeper Type

Sleeper TypeRecommended Firmness Range
Side SleepersMedium Soft to Medium Firm
Combination SleepersMedium to Medium Firm
Back SleepersMedium Firm to Firm
Stomach SleepersFirm to Extra Firm
Plus Size (250+ lbs)Firm to Extra Firm

✅ Shapeable firmness zones prevent sagging ✅ Breathability and airflow
✅ Easy transport and storage
✅ Customizable for two people

Durability and Longevity

Traveling full-time or weekend warrior style demands an RV king mattress built to handle constant motion. Prioritize these indicators of longevity:

  • High-density foams (>3 lb per cubic foot)
  • Reinforced, durable foam encasement
  • Adequate layers (10”+ total thickness)
  • The strong, breathable outer cover
  • At least 8-10 years total mattress warranty

6 Signs It’s Time to Replace Your RV Mattress

🛏️ Stains, damage, holes in cover
⏰ Over 7-10 years old

If you notice these, it’s time to shop around for a replacement RV king mattress

Average Lifespan by Mattress Type

  • Memory Foam – 5-7 years
  • Latex – 8+ years
  • Hybrid – 6-8 years
  • Innerspring – 5-7 years
  • Adjustable Air – 6-8 years

Tips to make your RV mattress last

  • Use a mattress protector from Day 1
  • Rotate head-to-toe every 6 months
  • Let moisture dry before covering
  • Fix tears in the cover ASAP

Pressure Relief and Spinal Alignment

Providing both ample cushioning and support helps keep the spine aligned, prevents future pain issues, and reduces tossing and turning.

Here’s how RV king mattresses accomplish both:

How RV Beds Can Impact Pressure Points

The shorter RV mattress length and confined space concentrate pressure:

  • On the shoulders and hips
  • Causing discomfort and soreness
  • Leading to tossing and turning

Thicker comfort layers provide the necessary cushioning to relieve these pressure points in RV sleepers.

Contouring Foam Reduces Discomfort

Memory foam in particular alleviates pressure very well, contouring to the body in response to heat and pressure.

It spreads weight evenly over the surface, acting like a customized sleeping surface every night.

Latex does this to a lesser degree as well.

Zoned Support Promotes Spinal Alignment

Reinforced edges on hybrid and innerspring RV mattresses provide support right up to the end of the bed so you don’t feel like you’ll roll off.

Strategically placed firmer and softer foams or coil zones support the areas that need it most like the shoulders, hips and lower back.

This keeps the spine properly aligned through the night regardless of sleeping position.

Motion Isolation

If you share an RV king bed with a partner, minimizing how much movement transfers from their side to yours makes sounder, more restful sleep possible.

How Design Impacts Motion Transfer

Foam and pocketed coil designs isolate motion best:

Memory foam absorbs motion very well before it can travel across the mattress.

Pocketed coil innersprings are wrapped in fabric so they compress individually instead of in unison like open coil designs. This prevents movement from extending past each coil.

Latex dampens motion to a lesser degree thanks to its responsive, bouncy quality.

Open coil mattresses with interconnected springs transfer the most motion between sleepers.

Temperature Regulation and Cooling

RV environments experience wide temperature fluctuations from storage areas under 90 F to deserts exceeding 100 F. Plus RVs are small, enclosed spaces.

Certain mattress materials and features help prevent overheating for more comfortable sleep:

Phase change materials absorb and release heat to maintain optimal temperature.

Gel infusions, like gel memory foam, also prevent heat buildup in the mattress core.

Graphite or copper in the foam formula pulls heat away from the body.

Breathable covers allow airflow near the sleeping surface.

Open cell structure foams enhance breathability throughout the mattress layers.

Innerspring coil layer allows superior airflow in hybrid models.

For the ultimate in cooling and comfort control, adjustable air mattresses allow each side to customize to their ideal firmness and support. See our top recommended model above.
