Wilderness Montana RV Mattress Review: A Real Upgrade for Full-Time RV Living!

Is this the most comfortable RV mattress for full-time RVers?

If you’ve ever spent a night on a factory-installed RV mattress, you know the struggle. Lumpy, thin, and uncomfortable beds are the norm, even in higher-end motorhomes. After 2.5 years on the stock 6-inch Denver Mattress in our Thor Challenger 37YT, we’d had enough.

We wanted a mattress that could give us the kind of sleep we enjoyed in our sticks-and-bricks home — something durable, supportive, and truly comfortable. That search led us to the Wilderness Montana Hybrid RV Mattress, and it completely changed how we sleep in our motorhome.

In this in-depth review, I’ll share why we chose the Montana Hybrid, what makes it stand out from other RV mattresses, and how it’s holding up after more than four years of full-time use.

Quick Verdict: Wilderness Montana RV Mattress

If you’re a full-time RVer or frequent traveler looking to replace the thin factory mattress that came with your rig, the Montana Hybrid is one of the most comfortable RV-specific upgrades we’ve personally experienced. Designed with multiple firmness options and common RV sizes, it offers a noticeable improvement in support, pressure relief, and overall sleep quality compared to many stock RV mattresses.

For RVers who want a more residential-style sleep experience without worrying about fitment issues, the Montana is a strong premium upgrade worth considering.

Who the Wilderness Montana RV Mattress Is Best For

Upgrading your RV mattress is a big comfort decision, especially if you travel or live in your motorhome full-time. Based on our experience using the Montana hybrid mattress, here’s who we believe will benefit most from this upgrade.

Full-Time RVers or Frequent Travelers

If you spend weeks or months at a time on the road, sleep quality becomes much more important than most people expect. The Montana offers significantly better support and comfort than the thin factory mattress that comes with many RVs, making it a great option for those who treat their RV like a home rather than a weekend camper.

Couples Needing Better Support and Stability

The hybrid construction helps reduce that “rolling toward the middle” feeling common with lightweight RV mattresses. If two people share the bed and want more consistent support across the sleeping surface, this mattress is a noticeable improvement.

Side Sleepers or Anyone Wanting More Pressure Relief

Many RV factory mattresses feel firm and unforgiving. The Montana’s pillow-top design adds cushioning that can help reduce pressure on hips and shoulders, which is especially helpful for side sleepers or anyone who wakes up sore after a night in the RV.

RV Owners Replacing a Worn or Uncomfortable Stock Mattress

If your current mattress is sagging, too thin, or simply uncomfortable, upgrading to an RV-specific mattress like the Montana can make a dramatic difference in overall sleep quality and daily comfort while traveling.

RVers Looking for Residential-Style Comfort Without Fitment Issues

Standard residential mattresses don’t always fit RV bed platforms properly. The Montana is designed with common RV sizes in mind, making it a practical upgrade for those who want better comfort without dealing with clearance or sizing problems.

Who This Mattress May Not Be Ideal For

While we’ve had a very positive experience with the Montana mattress, it may not be the best fit for every RVer.

Budget-Focused Shoppers

This is a premium RV mattress upgrade. If your primary goal is simply replacing a mattress at the lowest possible cost, there are cheaper options available.

Those Who Prefer an Ultra-Soft “Sink-In” Feel

The hybrid design offers balanced comfort and support rather than a deep memory-foam hug. RVers who prefer an extremely plush, hotel-style feel may want to compare firmness options carefully.

RVs With Very Limited Bed Height or Clearance

Before ordering, it’s important to measure your bed platform and overhead clearance. A thicker mattress can improve comfort but may also affect slide-out operation or storage space in some rigs.

That’s when we kept seeing one name pop up again and again: the Wilderness Montana Hybrid RV Mattress.

It had stellar reviews, was available in true RV sizes, and promised the kind of luxury sleep we were craving after years on a mediocre foam slab.

Factory RV Mattress vs Wilderness Montana Hybrid

Many RV owners don’t realize how much their sleep quality is being affected by the thin mattress that came with their rig until they experience an upgrade. While factory RV mattresses are designed to keep weight and cost down for manufacturers, they often lack the comfort and long-term support needed for extended travel or full-time living.

Here’s how the Wilderness Montana Hybrid compares.

Comfort and Support

Factory RV mattresses are typically thinner and use basic foam construction, which can lead to pressure points and restless sleep. Over time, they may begin to sag or feel uneven.

The Montana Hybrid combines supportive coils with comfort layers designed to provide a more balanced sleep surface. This can help reduce pressure on hips and shoulders while offering better overall support for both side and back sleepers.

Mattress Thickness and Feel

Stock RV mattresses are often only a few inches thick and can feel firm or unforgiving. While this helps keep costs low for RV manufacturers, it may not deliver the comfort many travelers want.

The Montana offers a thicker, more residential-style feel that many RVers find significantly more comfortable, especially during longer trips or full-time travel.

Durability Over Time

Because factory mattresses are built for mass production rather than long-term comfort, they may wear out faster with regular use.

An RV-specific upgrade like the Montana is designed with travel use in mind and may provide more consistent support over time compared to the mattress that originally came with your RV.

Fit and RV-Specific Sizing

Residential mattresses can sometimes be difficult to fit in RV bedrooms due to slide-out clearance, corner radii, or unique platform dimensions.

The Montana is available in common RV sizes, which can make installation easier and reduce the risk of ordering a mattress that doesn’t fit your space properly.

Overall Sleep Experience

For many RVers, upgrading from a factory mattress is one of the most noticeable comfort improvements they can make. Better sleep can make long travel days easier and help your RV feel more like home.

If your current mattress feels thin, worn, or uncomfortable, moving to a higher-quality RV-specific option like the Montana can be a meaningful upgrade.

Our Real-World Experience Sleeping on the Wilderness Montana Mattress

After spending extended time traveling and living in our RV, we quickly realized that the factory mattress simply wasn’t designed for long-term comfort. Like many RVers, we found it thin, lacking in support, and not ideal for getting consistent, restful sleep night after night.

Upgrading to the Wilderness Montana Hybrid made a noticeable difference in how comfortable the bed felt from the very first few nights. The additional thickness and hybrid construction provided better overall support compared to the stock mattress, and we found it helped reduce pressure points that can develop during longer trips.

One of the biggest improvements we noticed was how much more “residential” the bed felt. Instead of feeling like we were sleeping on a temporary solution designed mainly to save weight and cost, the Montana gave the RV bedroom a more home-like sleep experience. That can make a real difference when you spend weeks or months at a time on the road.

We also appreciated the stability of the mattress when moving or changing positions during the night. With two people sharing the bed, consistent support across the surface can help improve overall sleep quality, especially after long driving days or active travel schedules.

Like any mattress upgrade, comfort is subjective and depends on personal preferences, sleeping position, and firmness choice. However, for us, switching to an RV-specific mattress designed for comfort and support was one of the most worthwhile upgrades we’ve made to improve everyday livability in our motorhome.

Why We Chose the Montana Hybrid

• Built for full-time RVers: Designed with support, motion isolation, and long-term durability in mind
• Three comfort levels: Choose from Soft Pillowtop, Plush (our pick), or Firm
• Made to flex: Works perfectly with under-bed storage, adjustable bases, and slide systems

This wasn’t just a small upgrade — it was a complete sleep transformation. After years on a flimsy 6-inch RV mattress, the 10-inch-thick Montana Hybrid felt like a dream.

How to Choose the Right RV Mattress Size

One of the biggest mistakes RV owners make when upgrading their mattress is assuming that residential mattress sizes will fit their RV. In reality, many motorhomes, fifth wheels, and travel trailers use RV-specific mattress dimensions, so taking a few minutes to measure your space can save a lot of frustration.

Step 1: Measure the Mattress Platform

Before ordering a replacement mattress, remove your bedding and measure the actual bed platform — not the existing mattress. Measure:

• Length from headboard to foot
• Width from side to side
• Available height clearance (especially important in slide-outs or under cabinets)

Write these numbers down and compare them to the mattress sizes offered.

Step 2: Understand Common RV Mattress Sizes

Many RVs use sizes that are similar to residential mattresses but slightly shorter or narrower. Some of the most common RV mattress sizes include:

• RV Short Queen – Typically around 60″ x 75″
• RV Queen – Often similar to residential queen at 60″ x 80″
• RV King – Can vary widely depending on the manufacturer
• Three-Quarter or Custom Sizes – Found in some older rigs or compact layouts

Because sizes can vary by RV manufacturer and model year, measuring your space is always the safest approach.

Step 3: Consider Mattress Thickness and Clearance

Upgrading to a thicker, more supportive mattress can dramatically improve comfort, but it may also affect how easily you can sit up in bed or access overhead storage. In slide-out bedrooms, mattress height can even impact whether the slide fully retracts.

Make sure to check:

• overhead cabinet clearance
• window height
• slide-out operation
• ability to lift the bed platform for storage

Step 4: Think About Sleeping Style and Support Needs

Choosing the right size is only part of the decision. Consider how you sleep and how much space you need. Couples who move around at night or full-time RVers who prioritize comfort may prefer a larger mattress if their layout allows.

Taking the time to measure carefully and match the mattress size to your RV’s layout will help ensure your upgrade improves sleep quality without creating fitment issues.

How Easy Is It to Set Up the Montana Hybrid?

Here’s how it works:

1. Delivery: The mattress arrives in a sturdy box at your campsite, home, or any other location of your choice.
2. Unbox it: Carry the box into your RV bedroom. (Yes — it fits through the doorway without issue!)
3. Unroll & unwrap: Carefully remove the outer plastic and let the mattress expand. We used a simple letter opener to slice through the plastic wrap.
4. Let it rise: The mattress begins to expand immediately and reaches its full size within minutes.

We had it fully unboxed, placed, and ready to sleep on in less than 20 minutes — no special tools, no wrestling a giant mattress through tight RV hallways.

Pro Tip:

If your RV has a slide-out bed that folds when retracted or you rely on under-bed storage, the Montana Hybrid flexes well and works with adjustable bed bases. We’ve tested it with our Thor Challenger’s slide system, and it’s held up perfectly.

Our Sleep Experience: 48+ Months Later

We’ve now been sleeping on the Montana Hybrid Plush RV Mattress for over four years — and I can confidently say it’s the most comfortable mattress we’ve ever owned, RV or otherwise.

It has just the right balance of support and softness, cradling your body without that sinking memory foam feel. Whether you’re a back sleeper, side sleeper, or stomach sleeper, the Plush model offers a luxurious, hotel-quality sleep experience. Honestly, we’ve had friends climb onto our bed out of curiosity and say, “Wow… this is way better than my mattress at home.”

No Sagging, No Indents, No Regrets

One of the biggest problems with RV mattresses — especially the thin stock ones — is how quickly they start to sag or develop body impressions. After 2.5 years on our old mattress, we had deep valleys where we slept and a ridge in the middle.

After three full years on the Montana Hybrid?
✅ No indentations
✅ No sagging
✅ No difference in comfort from day one

Even with nightly use as full-time RVers, this mattress has maintained its shape and support, just as it did the day we unboxed it.

One Small Adjustment: Mattress Height

At 10 inches thick, the Montana Hybrid is significantly taller than the original 6-inch mattress that came with our rig. It took us a few nights to get used to climbing into bed, especially for Lisa, since we don’t have a step by the bed. But once you’re up there, you’re sleeping like royalty.

Built for RV Life: Flexibility You Can Count On

Need a Non-Standard RV Mattress? Build One That Fits Perfectly

That’s where Wilderness’s Custom Mattress Builder comes in.

With just a few quick measurements, you can design a mattress that fits your RV bed perfectly — no awkward overhang, no wasted space, no more wrestling with the wrong size. You even get to choose your comfort level, materials, and custom shape so your sleep feels just right, every night.

Whether you drive a Class A, tow a fifth wheel, or camp out in a teardrop, this tool gives you the flexibility to get exactly what you need, without compromising comfort or support.

Fitted Sheets That Actually Fit RV Beds

One of the frustrations we’ve all had as RVers is trying to force residential sheets to fit those odd RV mattress sizes. Too short, too tight, or sliding all over the place — it’s enough to drive you nuts in the middle of the night.

That’s why we also picked up a set of Trailblazer™ EZFit Sheets from Wilderness.

These aren’t your average stretchy sheets. They’re custom-designed to fit RV mattress dimensions perfectly, including those extra-thick mattresses like the 10” Montana Hybrid.

What Makes EZFit Sheets Great for RVers?

• Sized for RV mattresses — including RV Queen, RV King, Short King, and more
• Ultra-soft fabric — breathable and smooth like high-end hotel bedding
• Deep pocket fit — designed to stay put even on thicker hybrid mattresses
• Easy care — machine washable, wrinkle-resistant, and quick-drying

We’ve been using ours since upgrading our mattress, and the fit and feel are top-notch — no more corner clips, no bunching, and no frustration. They just work.

Pros and Cons of the Wilderness Montana RV Mattress

Upgrading your RV mattress is a personal decision that depends on comfort preferences, sleeping style, and budget. Based on our experience and overall impressions, here are some of the key advantages and potential drawbacks to consider before choosing the Montana Hybrid.

Pros

Significantly More Comfortable Than Many Factory RV Mattresses
The added thickness and hybrid construction provide improved support and cushioning compared to the thin foam mattresses commonly installed by RV manufacturers.

Balanced Support for a Variety of Sleeping Positions
The combination of comfort layers and supportive coils helps distribute body weight more evenly, which may reduce pressure points for side and back sleepers.

Designed for Common RV Mattress Sizes
Availability in RV-specific dimensions makes it easier to find a mattress that fits properly without needing to modify your bed platform or deal with clearance issues.

More Residential-Style Sleep Experience
Many RVers appreciate the upgraded feel, especially during longer trips or full-time travel when comfort becomes more important.

Potentially Better Long-Term Durability
A higher-quality mattress can maintain its support and structure longer than basic factory options, particularly with regular use.

Cons

Higher Cost Than Budget Replacement Mattresses
As a premium RV upgrade, the Montana may require a larger upfront investment compared to basic foam replacements.

Thicker Profile May Affect Clearance in Some RV Layouts
Before ordering, it’s important to measure available space to ensure the mattress height won’t interfere with slide-outs, cabinets, or storage access.

Comfort Preferences Vary by Sleeper
Firmness and feel are subjective. Some RVers who prefer an extremely plush or ultra-soft mattress may want to compare options carefully before choosing.

Shipping and Setup May Require Planning
Depending on RV size and location, receiving and installing a new mattress can take some preparation, especially for full-timers who move frequently.

Final Recommendation: Is the Wilderness Montana RV Mattress Worth It?

If you’re tired of the thin, uncomfortable mattress that came with your RV and want to improve your overall sleep quality on the road, the Wilderness Montana Hybrid is a premium upgrade worth serious consideration. In our experience, switching to a thicker, more supportive RV-specific mattress can make a noticeable difference in how rested you feel, especially during extended trips or full-time travel.

The Montana is designed with common RV sizes in mind and offers a more residential-style sleep experience compared to many factory mattresses. For RVers who prioritize comfort, support, and long-term durability, upgrading the mattress is one of the most impactful improvements you can make to your rig.

Of course, every sleeper has different comfort preferences and budget considerations. Taking the time to measure your mattress platform and choose the right firmness option will help ensure the upgrade meets your expectations.
