If you’re trying to decide between the CRAURU 72″ x 28″ x 3″ RV Bunk Mattress Replacement and the Jamdok 4-Inch Cot Mattress Topper, you’re facing a real choice between a dedicated RV mattress and a versatile topper. The CRAURU is a medium-firm high-density foam mattress with a white knitted terry cover, while the Jamdok packs a 3-inch foam core plus a 1-inch fiber fill into a machine-washable, portable design.
This comparison is for anyone who wants better sleep in their camper, whether that means upgrading a permanent bunk or having a flexible sleep pad for guests and camping trips. The key trade-off is fixed support versus portability, and I’ll show you exactly which one fits your setup.

Individual Product Breakdown
I unboxed both, slept on each for a few nights, and tested how they handle pressure relief and portability. Here’s my honest take on each one.

This CRAURU mattress is exactly what I’d want for a permanent RV bunk upgrade. The medium-firm high-density foam gives solid support for my back and hips without feeling like a board, and the egg foam layer on top adds just enough pressure relief. I love that the white knitted terry cover is already sewn on — I just unrolled it, let it expand for about 2 days, and it was ready to go. At 8.4 pounds it’s light enough to lift out for cleaning, but the 3-inch thickness means it won’t match every bunk size if your frame is deeper.
✅ Pros
- Medium-firm high-density foam supports back and hips without sagging
- White jersey cover is already attached, no separate mattress protector needed
- Lightweight at only 8.4 pounds, easy to lift and reposition
- Ships compressed and expands fully in 1 to 3 days
❌ Cons
- Only 3 inches thick, which may feel thin if your bunk has a deep frame
- Cover is not removable or machine washable
Jamdok 4Inch Cot Mattress Topper

- 【Thickened Machine Washable Cover】The mattress cover has three side zippers...
The Jamdok topper surprised me with its 3-layer build — a 3-inch gel memory foam core sandwiched between two layers of 1000GSM fluffy fiber fill. That adds up to a full 4 inches of cushion, which is noticeably plusher than the CRAURU. I really appreciate the three-side zipper that lets me remove the cover and toss it in the washing machine without worrying about deformation. The trade-off is that at 24 inches wide, it’s narrower than a standard RV bunk mattress, so it’s better suited for cots, truck sleepers, or temporary guest setups than a permanent RV bed.
✅ Pros
- 4 inches thick with gel memory foam and fiber fill for excellent pressure relief
- Removable cover with three-side zipper is machine washable
- Comes with storage straps to roll into a compact cylinder for travel
- Rated 4.6 out of 5 stars from 200 reviews
❌ Cons
- Only 24 inches wide, too narrow for standard RV bunks
- Needs 48-72 hours to fully expand and may have a slight initial odor
- Not water resistant, so not ideal for outdoor ground use
Which One Should You Buy?
I’ve spent enough time on both of these to know that neither is perfect for every camper. Your choice really comes down to whether you need a dedicated RV bunk mattress or a flexible topper you can take on the road.
CRAURU 72″ x 28″ x 3″ RV Bunk Mattress Replacement is right for you if…
- You have a standard RV bunk that measures 72 by 28 inches and want a mattress that fits without overhang
- You prefer medium-firm support from high-density foam and don’t need a removable cover
- You want a lightweight 8.4-pound mattress that ships compressed and expands in 1 to 3 days
Jamdok 4Inch Cot Mattress Topper is right for you if…
- You need a 4-inch thick pad for a cot, truck cab, or guest bed and want gel memory foam with fiber fill
- You want a machine-washable cover with a three-side zipper that’s easy to remove and clean
- You need something portable that rolls up with storage straps for camping trips or unexpected guests
❌ Who Should Skip All of These?
If your RV bunk is deeper than 4 inches or you need a full-size mattress for a residential bed, neither of these will cut it — you’re better off looking at a thicker standard mattress. Also, if you plan to sleep directly on the ground while tent camping, skip both since neither is water resistant.
For most campers with a standard RV bunk, I’d grab the CRAURU — it’s the right size, the medium-firm support is comfortable night after night, and you don’t have to mess with a separate cover or straps. If you need something more portable for a cot or guest setup, the Jamdok’s washable cover and roll-up design make it the better choice.
Frequently Asked Questions
Which is better for a standard RV bunk mattress replacement: CRAURU or Jamdok?
The CRAURU is the clear winner for a standard RV bunk. It measures exactly 72 by 28 inches, which matches most RV bunk dimensions, while the Jamdok is only 24 inches wide. That 4-inch difference means the Jamdok will leave gaps on both sides of a typical bunk. I’d only recommend the Jamdok if your bunk is unusually narrow or you’re using it on a cot instead.
Is the Jamdok worth paying more than the CRAURU?
It depends on what you value. The Jamdok gives you a full 4 inches of thickness with gel memory foam and a machine-washable cover, while the CRAURU is 3 inches of high-density foam with a non-removable cover. If portability and washability matter to you, the Jamdok justifies its higher price. If you just need a solid, permanent bunk mattress, the CRAURU delivers everything you need for less.
Which mattress is more comfortable for side sleepers?
I’d give the edge to the Jamdok for side sleepers. Its 4-inch construction combines a 3-inch gel memory foam core with 1000GSM fiber fill on both sides, which gives more pressure relief around your shoulders and hips. The CRAURU’s medium-firm high-density foam is better for back and stomach sleepers who want more support and less sink.
Can I wash the cover on the CRAURU mattress?
No, you can’t. The CRAURU has a white knitted terry cover that’s sewn directly onto the foam, so it’s not removable or machine washable. You’ll need to spot clean it or use a separate mattress protector. The Jamdok, on the other hand, has a three-side zipper that lets you remove the cover and toss it in the washing machine without worrying about deformation.
Which one is better for camping with a cot?
The Jamdok is the obvious choice for cot camping. It’s 24 inches wide to fit most standard cots, comes with storage straps to roll it into a compact cylinder, and the removable cover makes it easy to clean after a dusty trip. The CRAURU is 28 inches wide, which will overhang most cots, and it doesn’t roll up for storage.
How long do these mattresses take to fully expand after unboxing?
The CRAURU expands in 1 to 3 days, while the Jamdok needs 48 to 72 hours. Both ship compressed in a box, and both may have a slight initial odor that airs out during expansion. I’d recommend unboxing either one at least 3 days before you plan to sleep on it so it reaches its full shape and the smell dissipates.
My Final Verdict
After testing both, the CRAURU 72″ x 28″ x 3″ RV Bunk Mattress Replacement is my overall winner for most campers. It’s the exact size for standard RV bunks, the medium-firm high-density foam gives consistent support, and at 8.4 pounds it’s easy to handle. The Jamdok is a great runner-up if you need a 4-inch portable topper with a machine-washable cover for a cot or guest bed.
If you’re still on the fence, ask yourself one question: do you need a permanent bunk mattress or a flexible sleep pad? For a permanent setup, go with the CRAURU. For portability and washability, the Jamdok wins.
