Finding the Best RV King Size Mattress for Bedroom



Living in an RV, camper, or motorhome often means limited space. While RVs vary greatly in size and layout, many have a master bedroom large enough to accommodate a king-size mattress.

Upgrading to a king can provide more comfort and luxury during your travels. King RV mattresses allow couples to sleep closer together without feeling cramped. They also provide enough room for kids or pets to cuddle up and join you.

But finding the perfect king-size RV mattress involves some special considerations regarding size, construction, and installation in order to fit your RV bedroom properly. This guide will cover everything you need to know, from dimensions to mattress types to top-rated brands on the market.

What Size is a King Mattress in an RV?

The standard dimensions for a king size mattress are 76 inches wide by 80 inches long. However, RV mattresses may be a few inches narrower or shorter to accommodate tighter spaces.

Here are the common sizes to know when mattress shopping for an RV:

  • Standard King – 76” x 80”
  • Short King – 76” x 75”
  • Long King – 76” x 84”
  • Olympic Queen – 66″ x 80″
  • RV King – 72” x 75”

Measure the length and width of your RV’s bed platform before committing to a new mattress. Having the precise dimensions will ensure your chosen king mattress fits properly. Even an inch or two of difference can leave an uncomfortable gap or make it impossible to get the mattress down halls and around corners.

Many RV mattress manufacturers now offer king sizes tailored specifically to recreational vehicles, with shorter or narrower proportions. An RV short king of 72” by 75” gives just enough extra wiggle room while maximizing comfort.

Benefits of a RV King Size Mattress

More Comfortable for Couples

Traveling as a couple in an RV often means sharing smaller living quarters. Choosing an RV king mattress over a queen allows spouses or partners to sleep closer without compromising comfort. The 6 extra inches of width provides more space to stretch out.

Accommodate Kids or Guests

A king size bed provides plenty of room for kids to crawl in with mom and dad after a scary nightmare. Grandkids visiting for a weekend getaway can also pile in for late-night stories or cuddles. Some luxury RV king mattresses even convert to two twin beds for versatility.

Utilize Large Bedroom Spaces

Upscale fifth wheels and motorhomes often have master bedrooms designed to house a standard residential king mattress. Installing a plush king allows you to take full advantage of these large spaces for a decadent night’s rest.

Lay Completely Flat

RV queen beds often have rounded corners or gaps next to walls. This can cause you to sleep at an angle or curl up. An RV king-size mattress utilizes the entire flat surface, allowing your body to fully extend and align properly for maximum comfort.

RV Mattress Construction Types

Recreational vehicle mattresses need to meet different standards than regular beds. The confined spaces, humidity, temperature extremes, and frequency of movement in an RV require mattresses made of durable materials that resist mold, bacteria, sagging, and breakdown.

But RV mattresses should still feel comfortable! Here are the most common types of mattresses used for RVs:

Foam Mattresses

Foam is the most popular choice for RV beds because of its conforming comfort and compression abilities. RV foam mattresses contain materials like:

  • Memory Foam – The highest quality RV mattress foam. It conforms closely to the body, and provides pressure relief, yet regains its shape. More expensive but very comfortable.
  • Latex Foam – Made from rubber tree extracts. Naturally hypoallergenic and dust mite resistant. Bouncy, buoyant feel.
  • Polyfoam – The most affordable foam option. Varying densities provide different feels, from firm to plush.

Innerspring Mattresses

Traditional innerspring mattresses use metal coils or springs to provide cushioning. Models made specifically for RVs include:

  • Bonnell Coils – Hourglass-shaped springs tied together for a consistent sleep surface. Most budget-friendly option.
  • Pocketed Coils – Individual fabric sleeves reduce motion transfer between springs. More contouring.
  • Continuous Wire – Long single piece of steel wire coiled into rows. Unique feel but durable.

The coils in RV mattresses are shorter and more flexible than residential beds. This allows bending around tight corners as you install or remove it.

Air Mattresses

Inflatable mattresses offer versatile thickness. Simply add or release air to make it taller or shorter as needed. Easy to store. But prone to punctures.

Mattress Toppers

For a quick and budget option, use a memory foam, latex or wool mattress topper to soften an existing RV mattress. Toppers compress easily for storage and add extra cushioning.

Important Factors for Choosing an RV King Mattress

Choosing which construction type feels most comfortable is a personal decision. But there are a few key criteria RV mattress shoppers should consider:

  • Dimensions – Confirm your king mattress will properly fit the length and width of your RV bedroom’s flat platform or frame before purchase.
  • Adaptability – Choose durable materials that hold up well in temperature extremes from subzero nights to hot summer days.
  • Mold Resistance – Closed quarters and humidity cause mold and mildew. Seek out antimicrobial and hypoallergenic materials.
  • Weight – Heavier mattresses are harder to install and remove from tight spaces. Prioritize lighter foam over standard springs.
  • Thickness – Make sure your chosen depth allows closing storage under bed platforms. Too thick and lids won’t shut.
  • Spinal Alignment – Your RV mattress should keep the spine neutral. Combination sleepers need contouring and pressure relief at shoulders and hips.
  • Motion Isolation – When one partner moves or gets up, minimal transfer across the mattress allows the other to keep resting.
  • Durability – RV life means frequent packing up. Compressible foams regain original shape better long-term than coil springs.
  • Ease of Cleaning – From muddy hikes to late-night snacks in bed, choose water and stain-resistant outer covers for quick wiping.

Use this checklist when evaluating king size RV mattresses to find the right balance of comfort, support and practicality.

Where to Buy RV King Size Mattresses

While regular king-size mattresses fit some large RV bedroom spaces, the best selection for recreational vehicle-specific mattress lengths and widths are found through these sources:

  • Local RV Supply Stores – Shop in person to experience comfort levels by lying down on floor models. Ensure your precise needed dimensions before purchasing.
  • Direct from RV & Mattress Manufacturers – Many top brands now engineer RV-specific mattresses with enhanced features to withstand temperature extremes, humidity and road vibrations.
  • Online Retailers – Amazon ships a wide variety of compressed RV mattresses in all sizes and budgets, however, quality varies greatly. Stick to well-reviewed options.

Measure carefully and compare construction quality in addition to dimensions when shopping locally and online. All foam beds generally ship more compactly for easier installation than traditional innerspring options.

How Much Does a King RV Mattress Cost?

Pricing for King RV mattresses ranges widely based on materials, sizes, and features:

  • Budget Foam Mattresses – Basic all-foam mattresses start around $250-$350 for a king RV short size. These use cheaper polyurethane foam layers without specialized cooling gels or springs. Potential for faster breakdown but still an affordable upgrade.
  • Mid-Range Hybrid Options – Combining foam with coil springs improves support and durability over all foam. Expect to invest $400-$900 for a quality mid-range king. Great balance of comfort and value.
  • Luxury Brands – Top manufacturers using proprietary foams, latex support layers and hybrid materials can cost anywhere from $1,000 up to $2,500+ for a king RV mattress. But materials are exceptionally high-quality for comfort that lasts over a decade.

When comparing prices, also consider the usable surface area and price per square foot. An oversize residential king spread out over 76 inches by 80 inches means about 6,080 square inches of sleeping space. Some RV short kings at just 72” x 75” tallies to 5,400 square inches. Dividing the price by the square footage gives you the cost per inch – a helpful metric for weighing options.

And don’t assume higher prices guarantee superior quality or comfort. Carefully examine each mattress brand’s materials, certifications, and layers to make your own judgement on value versus budget picks.

Steps for Installing a King Mattress in an RV Bedroom

Once you select the ideal king size mattress for your RV model, follow these tips for smooth and proper installation:

  1. Remove Old Mattress & Clean – Take out existing mattress and thoroughly wipe down platform frame surface and surrounding bedroom walls/ceiling to eliminate any mold, mustiness and dust.
  2. Check Dimensions – Unroll your new mattress and allow plenty of time to fully expand width and length if compressed for shipping. Double check to confirm perfect fit in frame space before unwrapping fully.
  3. Position Mattress – For hybrid mattresses, orient coils and solid foam sides correctly before sliding into place according to packaging guidance. Many RV mattresses include helpful handles along the sides for easier maneuvering into tight spaces.
  4. Consider Mattress Pad – Placing a 1-3 inch mattress pad or topper adds extra surface cushioning and protects your investment. Look for waterproof fabrics since spills and accidents happen, especially with kids and pets camping along.
  5. Make the Bed – Apply sheets and bedding to finish your new luxury king bed setup! For RVs, choose fitted sheets with deep pockets and elastic all around to cling tightly to the mattress when driving over rough roads.

Now relax and enjoy peaceful nights with plenty of wiggle room to spread out and get cozy. Don’t forget to budget for new king size bedding when purchasing your mattress to adorn your new luxurious RV retreat.

Finding the Best King Mattress for RV Comfort

Investing in a high quality king size mattress lets you fully utilize those large RV bedroom spaces for exceptional comfort. Making the upgrades to sleep a couple more comfortably or have kids pile in on chilly camping mornings is priceless.

Hopefully this extensive RV mattress king size buying guide gave you all the research needed to select the perfect model suited to your recreational vehicle make and dimensions.
