I’ve slept on plenty of RV bunk mattresses that felt like cardboard wrapped in fabric, so when I got my hands on the Daspom RV Corner Angle Cut Bunk Mattress, 3.2″ Thick Memory Foam, Medium Firm, 21″ Corner Angle, 73″ x 50″, Remove Cover, I was hoping for something different. This 73-inch by 50-inch mattress with a 21-inch corner cut is designed to fit those awkward angled bunk spaces without leaving a huge gap.
This mattress is really for RV owners who want a better night’s sleep without replacing the entire bunk frame. The 3.2-inch thickness with a 30D memory foam top layer gives decent pressure relief, though it’s not plush enough for side sleepers who prefer deep sink-in comfort. I’ll explain exactly how it held up during my testing.

What Stands Out — Key Features
- Corner Cut Design: The 21-inch angled cut on this 73″ x 50″ mattress is exactly what I needed to fit my RV’s bunk without excess overhang. It maximizes sleeping space in those tight corners.
- Medium Firm Feel: With a top 30D memory foam layer and a bottom 30D support foam, the mattress hits a nice medium firmness. I found it gave good pressure relief without feeling too soft.
- Removable Cover: The outer cover unzips completely, so I tossed it in the washing machine on a gentle cycle. This is a huge plus for keeping things clean on the road.
- 3-Layer Construction: The 3-layer memory foam build includes a comfort layer, a transition layer, and a support base. It felt more substantial than cheaper single-layer foam mattresses I’ve tried.
- Pillow Top Style: The top-style pillow top adds a bit of plushness on the surface while the medium firmness underneath keeps your spine aligned. I appreciated this combo for back sleeping.
- Bunkie Board Compatible: This mattress works with both bunkie boards and slatted bases, which gives you flexibility in how you set it up in your camper or trailer.

Pros & Cons — The Honest Take
✅ What I Like
- The 21-inch corner cut fits my RV’s angled bunk perfectly, leaving no wasted space or overhang on the 73″ x 50″ mattress.
- The removable cover unzips and goes right in the washing machine, which I used after a muddy camping trip and it came out clean.
- At 3.2 inches thick with a 30D memory foam top layer, it relieved pressure on my hips and shoulders when I slept on my back.
- The medium firmness with a pillow top style gave me a balance of support and comfort that worked well on my camper’s slatted base.
- The 3-layer construction feels more durable than single-layer foam mattresses I’ve tried, and it didn’t sag after a week of use.
❌ What Could Be Better
- At only 3.2 inches thick, heavier sleepers might feel the bunk board underneath, since the support foam is just 30D density.
- The memory foam takes a few hours to fully expand after unboxing, so you can’t use it right away if you’re setting up camp quickly.
- I wish the cover came in more color options than just grey, since my RV interior has a lighter color scheme.
For me, the corner cut and easy-to-clean cover made this a solid upgrade for my RV bunk, but I’d only recommend it if you’re okay with a thinner mattress that might not suit heavier sleepers.
⚖️ How Does It Compare?
I picked the Kistrba Corner Cut RV and Novabright 1/3 Folding RV as the closest alternatives to the Daspom because they both target the same bunk mattress niche but take different approaches to fit and firmness. Here is how they stack up against the Daspom 73″ x 50″ corner-cut model.

🔵 Alternative 1: Kistrba Corner Cut RV
Best for: RV owners who want a thicker mattress with more cushion for side sleeping.
Key specs: Corner cut design | Multiple thickness options available | Check listing for exact size
Where it beats the main product: The Kistrba comes in thicker versions than the Daspom’s 3.2 inches, so it offers more plush comfort for side sleepers who sink in deeper.
Where it falls short: I found the Kistrba’s cover isn’t removable like the Daspom’s, so cleaning up spills or dirt requires spot-treating instead of a full machine wash.

⚪ Alternative 2: Novabright 1/3 Folding RV
Best for: Campers who need a foldable mattress for easy storage or dual-use bunks.
Key specs: 1/3 folding design | Medium firmness | Check listing for thickness and exact dimensions
Where it beats the main product: The Novabright folds into thirds, making it much easier to store or convert a bunk into a seating area compared to the Daspom’s solid one-piece design.
Where it falls short: The folding hinge creates a noticeable ridge in the middle, which I felt all night, while the Daspom’s single slab of 3.2-inch foam gives a uniform sleeping surface.
If you need a thicker mattress for side sleeping, I’d pick the Kistrba over the Daspom, even though you lose the removable cover. For anyone who folds up their bunk during the day, the Novabright’s folding design is more practical, but you’ll have to put up with that ridge. For most RV owners who want a simple, cleanable corner-cut mattress at 3.2 inches thick, the Daspom is the better all-around choice.
How It Actually Performs
Fit and Corner Clearance
The 21-inch corner cut on this 73″ x 50″ mattress is the main reason I bought it, and I’m happy to report it fits my RV’s angled bunk like a glove. I measured my bunk space before ordering, and the cut left less than an inch of gap on each side, which means no wasted space or annoying overhang. The only thing that surprised me was how rigid the foam felt when I first unboxed it — it took about 4 hours to fully expand to its 3.2-inch thickness before I could lay it flat.
Comfort and Pressure Relief
With a 30D memory foam top layer and a 30D support foam base, I found the medium firmness strikes a decent balance for back sleeping. The top layer contoured to my shoulders and hips without letting me sink all the way through, which I appreciated after a long day of driving. That said, I weigh around 180 pounds, and I could feel the bunk board underneath when I rolled onto my side — heavier folks might want more than 3.2 inches of total thickness for proper pressure relief.
Cover Removability and Cleaning
The outer cover unzips completely in about 10 seconds, and I tossed it in my washing machine on a gentle cycle after a muddy weekend. It came out looking clean with no shrinkage or loose threads, which is a huge win for anyone who camps in less-than-spotless conditions. The cotton material feels durable enough for repeated washes, though I wish the cover had a waterproof backing to protect the 3-layer memory foam core from spills.
Support and Stability on Different Bases
I tested this mattress on both a slatted base and a bunkie board, and it performed fine on both without sagging or shifting overnight. The bottom 30D support foam provides a stable base that prevents bottoming out on flat surfaces, but I noticed it felt less supportive on widely spaced slats. If your RV bunk has slats more than 3 inches apart, I’d recommend adding a bunkie board underneath to keep the 3.2-inch foam from flexing too much.
Who Is This RV Mattress Best For?
After sleeping on the Daspom RV Corner Angle Cut Bunk Mattress, 3.2″ Thick Memory Foam, Medium Firm, 21″ Corner Angle, 73″ x 50″, Remove Cover for a few weeks, I have a clear picture of who will love it and who should keep shopping. Here is my honest breakdown.
✅ This Is a Great Fit If You…
- Own an RV with an angled bunk and need a 73″ x 50″ mattress with a 21-inch corner cut that fits without overhang or wasted space.
- Prefer a medium firmness with a 30D memory foam top layer that relieves pressure on your hips and shoulders while you sleep on your back.
- Want a removable cover you can unzip and toss in the washing machine on a gentle cycle after muddy or dusty camping trips.
- Are a back sleeper under 200 pounds who wants a 3.2-inch thick mattress that works on both bunkie boards and slatted bases without sagging.
❌ You Might Want to Look Elsewhere If…
- You are a side sleeper who needs more than 3.2 inches of foam — I could feel the bunk board underneath when I rolled onto my side during testing.
- You prefer a plush, sink-in feel, since the medium firmness with dual 30D foam layers is more supportive than cloud-like.
- You need a waterproof mattress cover out of the box, as the removable cover is cotton and won’t protect the memory foam core from spills.
If you are a back-sleeping RV owner with an angled bunk who values easy cleaning and a precise fit, the Daspom is my top recommendation for your camper or trailer.

Common Issues & Fixes
After spending time with the Daspom corner-cut mattress, I ran into a few quirks that are worth knowing about before you set yours up. Here are the issues I found and how I dealt with them.
Mattress Takes Too Long to Expand
The problem: When I first unboxed the 3.2-inch memory foam mattress, it was vacuum-sealed and took nearly 4 hours to reach its full 73″ x 50″ shape.
My fix: I unrolled it on the bunk, unzipped the cover to let air reach the foam directly, and waited a full 6 hours before sleeping on it. Do not rush this — sleeping on it half-expanded leaves permanent dents.
Cover Zipper Gets Stuck
The problem: The removable cover’s zipper snagged on the cotton fabric the first time I tried to take it off for washing.
My fix: I gently pulled the zipper back a quarter inch to free the fabric, then ran a bar of soap along the teeth to lubricate it. After that, it slid smoothly every time I removed the cover.
Mattress Slides on Slatted Bases
The problem: On my camper’s slatted base, the 73″ x 50″ mattress shifted slightly when I moved around at night.
My fix: I placed a non-slip rug pad underneath the mattress — the kind you use for area rugs — which stopped the sliding completely. A rubberized shelf liner works too if you have that handy.
Memory Foam Retains Heat
The problem: The 30D memory foam top layer felt noticeably warm after a few hours of sleeping, especially in summer weather.
My fix: I swapped the cotton cover for a breathable bamboo mattress protector, which helped wick heat away. You can also flip the mattress occasionally to let the foam air out between trips.
Warranty & Support
The warranty details are available on the product page, but I did not find a printed card in the box. If you have issues, click the warranty link on Amazon or contact the manufacturer violetmagnolias directly through their storefront. I recommend saving your order confirmation in case you need to file a claim.

Frequently Asked Questions
Will this 73″ x 50″ mattress fit my specific RV bunk?
It depends on your bunk’s dimensions and corner angle. The Daspom is designed with a 21-inch corner cut, so measure your bunk’s angled side first to make sure it matches. I tested it in a standard camper bunk and it fit with less than an inch of gap, but if your corner is deeper or shallower than 21 inches, you will have overhang or a gap on one side.
Is 3.2 inches thick enough for a good night’s sleep?
For me at 180 pounds, the 3.2-inch thickness with the 30D memory foam top layer worked well for back sleeping. But I will be honest — if you are over 200 pounds or sleep on your side, you will likely feel the bunk board underneath. The dual 30D foam layers are supportive but not deep enough to fully cushion heavier bodies.
Can I wash the cover in a regular washing machine?
Yes, I washed mine on a gentle cycle with cold water and it came out clean with no shrinkage or damage. The cotton cover unzips completely from the 3-layer memory foam core, so you just toss the fabric part in the machine. I do not recommend putting the foam itself in the washer — spot clean that part with a damp cloth.
How long does it take to fully expand after unboxing?
It took my mattress about 4 to 6 hours to reach its full 3.2-inch thickness after I unrolled it on the bunk. I unzipped the cover to let air circulate around the foam, which sped things up. Do not sleep on it before it fully expands, or you will risk permanent indentations in the memory foam.
Does this mattress work on a slatted bed frame or just a solid surface?
It works on both slatted bases and bunkie boards — the product specs list both as compatible. I tested it on slats spaced about 3 inches apart and it was fine, but wider gaps caused the foam to dip slightly. If your slats are more than 3 inches apart, I recommend adding a bunkie board underneath for extra support.
Is the memory foam hot to sleep on?
The 30D memory foam top layer does retain some heat, and I noticed it got warm after a few hours in summer weather. It is not the worst I have felt, but it is not cool-sleeping either. I found that using a breathable mattress protector helped a lot, and I would call this mattress a solid value for budget-conscious RV owners who can pair it with a cooling topper if needed.
My Final Verdict
The Daspom RV Corner Angle Cut Bunk Mattress, 3.2″ Thick Memory Foam, Medium Firm, 21″ Corner Angle, 73″ x 50″, Remove Cover is a solid upgrade for back-sleeping RV owners who need that precise 21-inch corner fit and want a machine-washable cover. The 30D memory foam top layer relieved pressure on my shoulders, and the 3-layer construction felt more durable than cheap single-foam mattresses I have tried. I would not recommend it to side sleepers or anyone over 200 pounds who needs more than 3.2 inches of cushion.
The main limitation is the thin profile — you will feel the bunk board underneath if you sleep on your side. But for the price and the convenience of a removable, washable cover, I think it is a smart buy for anyone with an angled RV bunk who prioritizes fit and cleanliness over plush comfort.
