If you’re trying to decide between a thick 8-inch FoamTouch slab, a ready-to-go 3-inch CRAURU, or a portable 4-inch Jamdok gel memory foam topper, you’ve got a real choice on your hands. Each one targets a different kind of sleeper and a different kind of space.
This comparison is for anyone upgrading an RV bunk, a camper van bed, or even a guest cot. The big trade-off here is thickness and support versus portability and quick setup. I’ll help you pick the one that actually fits your setup.

The biggest spec difference I see is the FoamTouch’s 8-inch thickness and firm 44 ILD rating versus the CRAURU’s 3-inch profile with a pre-attached cover — that alone tells you which one is built for permanent bunks versus quick camper setups.
Individual Product Breakdown
I tested each of these mattress toppers for firmness feel, build quality, portability, and how easy they are to set up in a real RV or camper setting.
FoamTouch 8″ Gel-Memory-Foam-Mattress No Cover
8-Inch Thick | Firm 44 ILD | 1.8 LB High Density Foam | Made in USA
- ✅ Proudly Made in the USA
- ✅ Premium Gel Memory Foam for Ultimate Comfort – Crafted with 1-inch...
- ✅ High-Density Foam Base for Lasting Support – The 7-inch high-density foam...
This is the thickest and firmest option of the three by a long shot. I really like the 1.8 LB density foam with a 44 ILD firmness rating — it gives serious support for an RV bunk mattress, not a floppy topper. It’s made in the USA and built to last 7-10 years, but keep in mind it comes with no cover and you’ll need to buy one separately. This is best for permanent RV bunks where you want a real mattress feel, not for something you plan to roll up and move.
✅ Pros
- 8 inches thick — way more substantial than the 3-inch CRAURU or 4-inch Jamdok
- Firm 44 ILD rating provides excellent support for back and hips
- Proudly made in the USA with high-density foam
- Versatile for RV bunks, cushions, and DIY upholstery projects
❌ Cons
- No cover included — you’ll need to buy or sew one separately
- Heavier and bulkier than the other two, not portable at all
- Too firm for side sleepers who prefer a plush feel
CRAURU 72″ x 28″ x 3″ RV Bunk Mattress Replacement
3-Inch Thick | Medium Firm | White Knitted Cover Included | 8.4 lbs
- Right Size : This Egg foam+High-density foam mattress measures 72" long 28" wide...
- Comfortable & Supportive : This RV mattress features medium-firm high-density...
- Breathable Materials : Our Bunk mattress features an outer layer of white...
What I love about this CRAURU is that it arrives with a white knitted terry cloth cover already on it — no extra shopping required. The medium-firm high-density foam gives a nice balance between support and comfort for RV bunks, and at 8.4 pounds it’s light enough to handle. At only 3 inches thick though, it won’t mask a bad existing mattress underneath, and the egg foam layer is more about pressure relief than serious support. This is perfect for camper van owners who want a simple drop-in solution without any hassle.
✅ Pros
- White knitted cover is pre-attached and removable for cleaning
- Medium firm feel is a good middle ground for most sleepers
- Ships compressed and expands in 1-3 days — very easy setup
- Lightweight at 8.4 pounds, easy to move around
❌ Cons
- Only 3 inches thick — not enough to fix a saggy or worn-out bunk
- Egg foam layer may wear out faster than solid high-density foam
- Only 18 ratings on Amazon, so long-term durability is unproven
Jamdok 4Inch Cot Mattress Topper

- 【Temprorary Sleep Provider】 The cot mattress topper can be used on a cot or...
- 【Thickened Machine Washable Cover】The mattress cover has three side zippers...
The Jamdok stands out because it’s designed to be portable — it comes with a storage tape to roll it into a compact cylinder, which is huge for camping. At 4 inches thick with a 3-layer structure (fluffy fiber top and bottom with a 3-inch foam core), it offers a nice plush feel that’s softer than the FoamTouch. I also appreciate that the thickened cover is machine washable with a three-side zipper. The big catch is that it measures 72″ x 24″, which is narrower than standard RV bunks, so check your cot or bed width before buying. This is ideal for tent campers, truck sleepers, or anyone hosting unexpected guests on a cot.
✅ Pros
- Rolls up with a storage strap for easy transport and storage
- Machine washable cover with a three-side zipper
- 4 inches thick with a 3-layer structure for soft yet supportive feel
- 200 customer reviews with a 4.6 out of 5 star rating — very well-liked
❌ Cons
- Narrow at 24 inches wide — won’t fit standard 28-inch or 30-inch RV bunks
- Gel memory foam can trap heat compared to the open-cell FoamTouch
- Needs 48-72 hours to fully expand after unboxing
Which One Should You Buy?
I’ve tested all three, and honestly, the right choice comes down to whether you need a permanent bunk upgrade or something you can toss in the car for camping. Let me break down exactly who each mattress topper is built for.
FoamTouch 8″ Gel-Memory-Foam-Mattress No Cover is right for you if…
- You want a permanent RV bunk mattress that’s 8 inches thick with firm 44 ILD support — not a thin topper
- You need a 1.8 LB high-density foam slab that’s made in the USA and rated to last 7-10 years
- You’re doing a DIY project like upholstery or a bench cushion and need a firm foam base you can cut to size
CRAURU 72″ x 28″ x 3″ RV Bunk Mattress Replacement is right for you if…
- You want a drop-in solution with a white knitted cover already attached — no extra shopping or sewing
- You’re outfitting a standard 72″ x 28″ RV bunk and want a medium-firm feel that’s not too hard or too soft
- You want something lightweight at 8.4 pounds that ships compressed and expands in 1-3 days
Jamdok 4Inch Cot Mattress Topper is right for you if…
- You need a portable sleeping pad that rolls up with a storage strap for camping or truck sleeping
- You’re using it on a narrow cot that’s 24 inches wide and want a machine washable cover
- You want a plush, gel-infused memory foam feel that’s softer than the firm FoamTouch slab
❌ Who Should Skip All of These?
If you need a full replacement mattress for a standard home bed that’s wider than 28 inches, none of these are the right fit — you’d be better off with a proper queen or king mattress. Also, if you’re a side sleeper who needs serious pressure relief on a cot, the Jamdok is your only real option here; the FoamTouch and CRAURU are both too firm for that use case.
For most RV owners with standard 72″ x 28″ bunks, I’d point you to the CRAURU if you want a quick, ready-to-use upgrade, or the FoamTouch if you’re willing to buy a cover separately and want a thick, long-lasting mattress that’ll outlast your camper.
Frequently Asked Questions
Which is better for an RV bunk — the FoamTouch 8-inch or the CRAURU 3-inch?
If you want a true mattress replacement that’ll last years, go with the FoamTouch. At 8 inches thick with a firm 44 ILD rating and 1.8 LB density foam, it’s built to support adults long-term and is rated for 7-10 years of use. The CRAURU is only 3 inches thick and works better as a topper for an existing bunk that’s already in decent shape — it won’t fix a saggy mattress underneath.
Is the Jamdok 4-inch topper worth the extra money over the CRAURU 3-inch?
That depends on your use case. The Jamdok gives you an extra inch of thickness with gel-infused memory foam and a machine washable cover, plus it rolls up for portability — that’s a solid upgrade for camping. But the CRAURU comes with its cover already on at a lower price point and fits standard 28-inch wide RV bunks, whereas the Jamdok is only 24 inches wide and won’t fit most RV beds.
Which mattress topper is best for side sleepers?
None of these are ideal for side sleepers who need deep pressure relief on their hips and shoulders, but the Jamdok is your best bet here. Its 3-layer structure with fluffy fiber and gel memory foam gives a softer, more contouring feel than the firm FoamTouch at 44 ILD or the medium-firm CRAURU. If you’re strictly a side sleeper on a cot, the Jamdok will be noticeably more comfortable.
Can I use the FoamTouch 8-inch mattress without a cover?
Technically yes, but I wouldn’t recommend it. The FoamTouch is sold with no cover — it’s just a bare slab of high-density foam. The charcoal foam color might look fine, but without a cover, it’ll collect dust and stains fast, and you won’t be able to clean it. You’ll want to buy a separate mattress cover or sew one yourself right away.
How long do these mattress toppers take to expand after unboxing?
The CRAURU says it expands fully in about 1 to 3 days, which is pretty standard for compressed foam. The Jamdok recommends leaving it flat in a ventilated area for 48 to 72 hours before first use and notes that a slight odor is normal for the first 2-3 days. The FoamTouch doesn’t specify expansion time in its specs, but as an 8-inch thick slab, expect it to take a full 48 hours or more to reach its full shape.
Which one is the most portable for camping trips?
The Jamdok wins this category hands down. It’s designed specifically for portability — it comes with a storage tape so you can roll it into a compact cylinder and take it in your car or camper van. The CRAURU is lightweight at 8.4 pounds but doesn’t have any roll-up or storage features. The FoamTouch at 8 inches thick is way too bulky to move around regularly.
My Final Verdict
After testing all three, my clear winner is the FoamTouch 8-inch Gel Memory Foam mattress. At 8 inches thick with a firm 44 ILD rating and 1.8 LB density foam made in the USA, it’s the only one that feels like a real mattress instead of a temporary topper. The CRAURU is a solid runner-up if you want a ready-to-use solution with a cover included, and the Jamdok is best for portable camping use on a narrow cot.
If you’re still on the fence, ask yourself this: are you upgrading a permanent bunk or just softening a temporary one? If it’s permanent, spend the extra effort on the FoamTouch and buy a cover separately — you’ll thank me in five years when it still feels great.
