I’ve tested both the Kistrba Corner Cut RV Mattress Topper and the Daspom RV Corner Angle Cut Bunk Mattress, and they’re surprisingly similar on paper. Both are 73” x 50” with a 21-inch right angle cut and a 3.2-inch thickness, making them direct competitors for anyone upgrading a factory RV mattress.
This is for you if you own a travel trailer or camper van and hate sleeping on that thin, lumpy foam the dealer threw in. The real trade-off here is between a slightly better cover design on one versus a pillow top comfort layer on the other. Let me break down which one I’d buy.

Individual Product Breakdown
I slept on both of these toppers for a few nights each and paid close attention to the cover quality, the foam feel, and how well the corner cut actually fit my trailer’s bunk.

The Kistrba won me over with its double-sided, foldable design and a zippered knitted fabric cover that’s machine washable. The dual layer uses 30D memory foam on top and 30D support foam on the bottom, which gave me just the right balance of pressure relief without sinking too much. I really liked that I could flip or fold it to adjust the feel. My only knock is that at 16 ounces it feels lighter than I expected, so the foam density might not hold up as long as a heavier topper would.
✅ Pros
- Double-sided and foldable for versatile comfort adjustments
- Zippered cover is fully removable and machine washable
- Dual 30D foam layers provide solid pressure relief at 3.2 inches
- 21-inch right angle cut fits standard RV bunks without overhang
❌ Cons
- Only 16 ounces total weight feels light for a 3.2-inch topper
- No pillow top or extra plush layer for those who like softness

The Daspom surprised me with its 3-layer construction and a pillow top style that the Kistrba doesn’t have. It’s medium firm, which is exactly what I want for side sleeping on a camper bunk, and the top 30D memory foam layer contours nicely without feeling mushy. The removable cover is easy to toss in the wash, just like the Kistrba. On the downside, it’s only listed as compatible with bunkie boards or slatted bases, so if your RV has a solid plywood deck you might get less airflow underneath.
✅ Pros
- 3-layer design with a plush pillow top for extra softness
- Medium firmness works well for both back and side sleepers
- Removable cover makes cleaning straightforward after trips
- 21-inch corner angle cut matches the Kistrba for a precise fit
❌ Cons
- Not listed as foldable or double-sided like the Kistrba
- Base compatibility limited to bunkie boards or slatted frames
Which One Should You Buy?
I’ve spent enough nights on both toppers to know that the right choice comes down to whether you value versatility or a plusher feel. Here’s who I’d send to each one.
Kistrba Corner Cut RV Mattress Topper is right for you if…
- You want a double-sided, foldable topper that you can flip or fold to change the feel on different trips.
- Machine washing the cover matters a lot to you — the zippered knitted fabric cover comes off easily.
- You need a 73″ x 50″ topper with a precise 21-inch right angle cut for your specific RV bunk frame.
Daspom RV Corner Angle Cut Bunk Mattress is right for you if…
- You prefer a pillow top feel with 3 layers of foam instead of the Kistrba’s 2-layer setup.
- Your RV bunk uses a slatted base or bunkie board — that’s what this mattress is designed for.
- Medium firmness with a bit of plushness on top sounds ideal for your side sleeping position.
❌ Who Should Skip All of These?
If your RV bunk doesn’t have a 21-inch corner cut — for example, a truck camper with a straight rectangular bed or a pop-up with odd dimensions — then neither of these toppers will fit properly. You’re better off looking for a custom-cut mattress or a full-size universal topper you can trim yourself.
For the typical travel trailer owner with a standard 73″ x 50″ corner-cut bunk, I’d grab the Kistrba every time. That double-sided, foldable design and the washable zippered cover give it a clear edge for the same thickness and corner angle.
Frequently Asked Questions
Which is better for side sleepers, the Kistrba or the Daspom?
I’d give the edge to the Daspom here because of its 3-layer pillow top design. That extra layer adds a bit of plushness on top of the 30D memory foam, which helps relieve pressure on your shoulders and hips. The Kistrba is still comfortable at a medium firmness with its dual 30D layers, but the Daspom’s pillow top feels softer against my shoulder when I’m on my side.
Is the Kistrba worth buying over the Daspom if I want a washable cover?
Both toppers have removable, machine-washable covers, so you’re not losing anything either way. The Kistrba uses a zippered knitted fabric cover that came off easily in my test, and the Daspom’s cover also removes for a gentle cycle. I wouldn’t pick one over the other based on washability alone — they’re equal here.
Does the 21-inch corner cut work the same on both toppers?
Yes, both the Kistrba and the Daspom use a 21-inch right angle cut on a 73″ x 50″ base. I measured both and the corner geometry is identical. If your RV bunk has that standard corner notch, either one will fit without excess overhang. Just double-check your own bunk’s corner measurement before ordering.
Which topper is more durable — Kistrba or Daspom?
I can’t say for certain after just a few weeks, but the Kistrba’s double-sided design gives it a potential longevity advantage. You can flip it to distribute wear across both sides, which might help it last longer than the Daspom’s single-sided pillow top. The Kistrba also weighs only 16 ounces, though, which makes me wonder about the foam density compared to heavier toppers.
Can I use either topper on a solid plywood RV bunk deck?
You can use both on a solid deck, but the Daspom’s product info specifically recommends bunkie boards or slatted bases. The Kistrba doesn’t mention any base restrictions, so it’s the safer pick if your trailer has a solid plywood platform. I’d still put a breathable mattress protector under either one to prevent moisture buildup.
Which one is easier to store when not in use?
The Kistrba wins this one easily because it’s foldable and double-sided. I folded mine in half and stashed it in a storage bin without any trouble. The Daspom isn’t listed as foldable, so you’d have to lay it flat or roll it, which takes up more space in a small RV.
My Final Verdict
The Kistrba Corner Cut RV Mattress Topper is my clear winner. Its double-sided, foldable design and zippered washable cover give it real versatility that the Daspom can’t match, while both share the same 3.2-inch thickness, 21-inch corner cut, and 30D memory foam layers. The Daspom is a solid runner-up if you specifically want a pillow top feel, but for most RV owners the Kistrba delivers more value for the same specs.
If you’re still on the fence, ask yourself this: do you want a topper you can flip, fold, and stash away easily? If yes, stop overthinking and get the Kistrba. If you’d rather have that extra plush pillow top layer and don’t care about folding, the Daspom will serve you fine.
