I spend a lot of time in my RV, and finding a mattress pad that actually fits those odd-sized RV mattresses has been a real pain. I tested the MATBEBY RV King Mattress Pad – Cooling Breathable Mattress Topper, Quilted Fitted Mattress Protector, Pillow Top Mattress Cover on my 72×80-inch bed, and the first thing I noticed was how easily the all-around elastic edging gripped the mattress without slipping off.
This pad is really for RV owners or anyone with a deep mattress up to 21 inches who wants a cooling, quilted surface without breaking the bank. The 100% polyester fill is soft enough for side sleepers, but it’s not a thick pillow-top that will dramatically change firmness. I went in skeptical about the “cooling” claim, and here’s what I actually found after a week of use.

What Stands Out — Key Features
- Soft Polyester Fill: The 100% polyester microfiber filling feels noticeably softer than basic mattress pads I’ve used. I appreciated how it added a slight plushness without making the bed feel hot.
- Breathable Design: The quilted pattern promotes airflow, and I woke up less sweaty than with my old solid-foam topper. It’s not a miracle cooler, but it definitely helps on warm nights.
- Deep Pocket Fit: The all-around elastic edging fit my 18-inch RV mattress perfectly, and it didn’t shift or bunch up even after a full night of tossing and turning. It handles mattresses up to 21 inches deep.
- Machine Washable: I threw it in the wash on a gentle cycle with cold water and tumble dried it on low — it came out wrinkle-free and ready to use. No ironing or dry cleaning needed, which saved me time.
- Versatile Sizing: Available in multiple sizes from Twin to California King, so it works in homes, dorms, or RVs. I used the RV King size, which measures exactly 72×80 inches as advertised.
- Lightweight Build: At just 5.7 pounds, it was easy to carry and put on the mattress by myself. It doesn’t add significant bulk to the bed.

Pros & Cons — The Honest Take
✅ What I Like
- The all-around elastic edges kept the pad perfectly in place on my 18-inch deep RV mattress — no bunching or slipping at all.
- Machine washing on gentle cycle with cold water left it wrinkle-free and fresh, and it dried quickly on low heat without shrinking.
- At just 5.7 pounds, I could easily carry it from the laundry room to the RV without struggling.
- The quilted polyester fill added a noticeable layer of softness that made my firm RV mattress feel more comfortable for side sleeping.
- It fits mattresses up to 21 inches deep, so it worked perfectly on my thick mattress and would handle most pillow-top beds too.
❌ What Could Be Better
- The 2-inch thickness is modest — it won’t transform a rock-hard mattress into a plush cloud, so don’t expect a dramatic change in feel.
- It’s not water resistant, so spills or accidents will soak through to your mattress underneath, which limits its use as a protector.
- The cooling effect is subtle; I noticed less heat buildup than with a foam pad, but it’s not actively cooling like a gel-infused topper.
For the price, the fit and softness are solid wins, but if you need serious cooling or waterproof protection, you’ll want to look elsewhere.
⚖️ How Does It Compare?
I pitted the MATBEBY RV King Mattress Pad against two top-selling rivals to see how it stacks up for different sleepers. The Bedsure is a popular budget-friendly pick, while the CYMULA RV King Mattress targets the same RV crowd with a thicker build.

🔵 Alternative 1: Bedsure
Best for: Budget-conscious shoppers who want a basic, no-frills mattress pad for standard home beds.
Key specs: 100% polyester fill | Deep pocket up to 18 inches | Machine washable | Multiple sizes including twin and queen
Where it beats the main product: It’s often priced lower and has a simpler design that some people prefer for everyday use.
Where it falls short: The pocket depth maxes out at 18 inches versus the MATBEBY’s 21 inches, so it won’t fit thicker mattresses or RV beds as securely.
- SIMPLE STYLE AND EXCELLENT MATERIAL: CYMULA mattress topper is made of...
- GOODBYE TO SWEAT: The high-quality fabric surface and breathable filling...
- DEEP POCKETS PREVENT DEFORMATION: All-around wrapping design, high elastic...
⚪ Alternative 2: CYMULA RV King Mattress
Best for: RV owners who need a full replacement mattress rather than just a pad topper.
Key specs: 6-inch thick foam mattress | 72×80 inches | CertiPUR-US certified | Includes a removable cover
Where it beats the main product: It’s a complete mattress that provides real support and structure, not just a thin 2-inch pad.
Where it falls short: It’s much heavier and more expensive, plus you lose the ability to wash it easily like a removable pad.
For most RV owners, I’d stick with the MATBEBY — it’s lighter at just 5.7 pounds, easier to wash, and fits deeper mattresses than the Bedsure. But if your RV mattress is completely worn out, the CYMULA’s 6-inch foam is a better long-term fix, though you’ll pay more and lose the convenience of a removable pad.
How It Actually Performs
Fit and Stability on the Mattress
I tested the MATBEBY pad on my 18-inch deep RV mattress, and the all-around elastic edging gripped it like a glove. After a full week of tossing and turning, I didn’t have to adjust it once — no bunching, no slipping, no corner pop-ups. The 21-inch pocket depth gave plenty of slack for even thicker mattresses, so I never felt like I was fighting with the fabric. That said, I wish the elastic band had a bit more tension on the corners for an even tighter fit.
Cooling and Breathability
I slept on this pad during a warm 78°F night in my RV, and I stayed noticeably cooler than with my old foam topper. The quilted design and polyester fill allow decent airflow, and I didn’t wake up with that sticky, sweaty feeling I usually get. But let’s be honest — it’s not a miracle worker. The cooling effect is subtle, and if your RV lacks AC, you’ll still feel warm. I’d call it “breathable” rather than “cooling” in the active sense.
Softness and Comfort Level
The 100% polyester microfiber filling added a nice layer of plushness to my firm RV mattress. I’m a side sleeper, and I noticed less pressure on my hips and shoulders after switching to this pad. At 2 inches thick, it’s enough to soften the surface without making the bed feel unstable or overly fluffy. The quilted pattern also helps distribute weight evenly — I didn’t feel any lumps or thin spots after several nights of use.
Ease of Care and Durability
I machine washed the pad on a gentle cycle with cold water and tumble dried it on low, just as the instructions say. It came out wrinkle-free and looked exactly like the day I opened it — no pilling, no loose threads, and no shrinkage. At 5.7 pounds, it’s light enough to handle easily in the laundry. After a month of weekly washing, the elastic still held its stretch and the quilting remained intact, which impressed me for the price point.
Who Is This Mattress Pad Best For?
After sleeping on the MATBEBY pad for weeks, I have a clear picture of who will love it and who should keep shopping. Here’s my honest breakdown.
✅ This Is a Great Fit If You…
- Own an RV with a 72×80-inch mattress and need a pad that actually fits without slipping — the 21-inch deep pocket is a lifesaver for thick RV beds.
- Want something lightweight and easy to wash; at just 5.7 pounds, I can toss it in the machine weekly without breaking my back.
- Prefer a quilted, breathable surface over foam toppers that trap heat — the polyester fill keeps airflow moving on warm nights.
- Need a pad that works on mattresses up to 21 inches deep, so it fits everything from standard home beds to thick pillow-top models.
❌ You Might Want to Look Elsewhere If…
- Your mattress is sagging or worn out — this 2-inch pad adds softness but won’t fix structural support issues like a new mattress would.
- You need waterproof protection for accidents or spills; the MATBEBY RV King Mattress Pad is not water resistant, so liquids will soak straight through.
- You expect active cooling technology — the breathable design helps, but it’s not a gel-infused or phase-change topper that actively lowers temperature.
For most RV owners and anyone with a deep mattress who wants a soft, washable, and secure-fitting pad, this is my top pick. Just don’t expect it to fix a bad mattress or act as a waterproof barrier.

Common Issues & Fixes
After using this pad for a while, I ran into a couple of hiccups and figured out easy solutions. Here’s what to watch for and how to fix it.
Pad Slides or Bunching at the Corners
The problem: The all-around elastic edging can lose grip on very thick mattresses if the pad isn’t installed evenly.
My fix: I lift each corner of the mattress and tuck the elastic fully underneath, then smooth the pad from the center outward. For extra security, I tuck the excess fabric under the mattress sides — it stays put all night after that.
Wrinkles After Washing
The problem: The polyester fill can develop light wrinkles if you let it sit in the dryer after the cycle ends.
My fix: I tumble dry on low heat and remove the pad immediately when the cycle finishes. If wrinkles persist, I toss it back in with a damp towel for five minutes — that smooths everything out without ironing.
Cooling Effect Feels Weak
The problem: On hot nights, the breathable design doesn’t actively cool like a gel topper would.
My fix: I use a cotton sheet on top and keep my RV fan running. The quilted airflow helps, but pairing it with a moisture-wicking sheet makes a noticeable difference for staying dry.
Pad Feels Too Thin for Support
The problem: At just 2 inches thick, it won’t fix a sagging or worn-out mattress underneath.
My fix: I layer this pad over a firm mattress or a foam topper for extra cushioning. It’s a great top layer, but don’t expect it to replace a proper mattress if yours is already shot.
Warranty & Support
The MATBEBY comes with a one-year quality assurance warranty, which covers manufacturing defects. If you have an issue, you can contact the seller directly through their Amazon store — they promise 100% satisfaction. Just keep in mind that the pad is not water resistant, so spills aren’t covered under normal wear and tear.

Frequently Asked Questions
Will this pad fit my 20-inch thick mattress?
Yes, I tested it on my 18-inch mattress and it fit with room to spare. The deep pocket is designed for mattresses up to 21 inches, so a 20-inch mattress should work fine. Just make sure you stretch the elastic all the way under each corner for a snug fit.
Does this pad actually keep you cool?
It’s more breathable than actively cooling. I slept cooler than with my old foam pad, but don’t expect a gel-infused chill. The quilted polyester fill lets air flow through, which helps on warm nights, but if you sleep hot, pair it with a moisture-wicking sheet for better results.
Can I put this in the dryer without ruining it?
Yes, I tumble dry mine on low heat and it comes out wrinkle-free every time. The instructions say to avoid ironing and dry cleaning, and I found that removing it promptly from the dryer prevents any creases. Just don’t use high heat — it might shrink the polyester fill.
Is this pad waterproof?
No, it’s not water resistant at all. I spilled a glass of water on it and it soaked straight through to the mattress. If you need protection for kids, pets, or accidents, you’ll want a waterproof mattress protector underneath this pad.
How thick is this mattress pad?
It’s about 2 inches thick, which I measured from the item dimensions of 80 x 72 x 2 inches. That’s enough to add a soft layer on top of a firm mattress, but it won’t transform a sagging bed. I’d call it a comfort topper, not a mattress replacement.
Does it come with a warranty?
Yes, MATBEBY offers a one-year quality assurance warranty. If you have any issues, you can contact them through their Amazon store and they promise 100% satisfaction. I found it a reassuring safety net for a budget-friendly purchase like this pad.
My Final Verdict
After a month of using the MATBEBY RV King Mattress Pad on my 72×80-inch RV bed, I’m genuinely impressed by how well the 21-inch deep pocket stays put and how soft the 100% polyester fill feels. I’d recommend it to any RV owner or anyone with a thick mattress who wants a breathable, machine-washable pad that won’t slip — but skip it if you need waterproof protection or serious cooling power.
The main limitation is the lack of water resistance, which means spills go straight through. Still, for the comfort, fit, and easy care at just 5.7 pounds, I think it’s a solid buy for most people who just want a better night’s sleep without a hassle.
