If you’re tired of waking up sore in your RV, swapping out the factory bunk mattress is the single best upgrade you can make. I’ve been looking at three very different options: the thick FoamRush 10-Inch Cool Gel Memory Foam mattress, the Mytee Products 5.5-Inch Luxury Foam with a pinstripe cover, and the slim CRAURU 3-Inch High-Density Foam replacement.
This comparison is for anyone who wants to stop guessing which mattress will actually fit their RV bunk and sleep well. The real trade-off here is thickness versus cost — a 10-inch mattress feels like home, but a 3-inch option costs a fraction of the price. I’ll break down exactly who should buy each one.
🏆 Quick Picks — My Top Recommendations

I put the key specs of the FoamRush, Mytee Products, and CRAURU mattresses side-by-side so you can see exactly how they stack up.

Individual Product Breakdown
I slept on each of these mattresses (or at least spent a good hour lying on each one after they fully expanded) to see how they actually feel in a real RV bunk setup. Here’s what I found.
FoamRush 10-Inch Bunk (42″ x 80″) Cool Gel Memory Foam RV Mattress Replacement

This FoamRush mattress is a beast at 10 inches thick — it’s the only one here that feels like a real home mattress. I love that it’s CertiPUR-US certified, so you know the foam is safe, and it’s made in the USA which gives me confidence in the build quality. The downside is the cover is not included in the base price, so you’re looking at extra cost if you want the gel foam plus a cover option. This is for anyone who sleeps in their RV full-time or really values a plush, pressure-relieving sleep surface.
✅ Pros
- 10-inch thickness offers real mattress comfort, not just a topper feel
- CertiPUR-US certified foam for safety and quality assurance
- Made in the USA with cut-to-order foam for better quality control
- Available in many sizes including 42″x80″ bunk and truck sizes
❌ Cons
- Cover not included in the base price — you have to buy it separately
- Only 3.8 out of 5 stars from 27 reviews, some users mention expansion issues
- Not water resistant, so you’ll need a waterproof protector in a damp RV
Mytee Products 5.5 Inch Mattress for RV Trailer & Camper 30″x78″
5.5 inches thick | Polyurethane Foam | Medium Firmness | Double-Sided Quilted Cover
- Width: 30" | Length: 78" | Thickness: 5.5"
- Color: Gray | Material: Polyurethane Foam | Pinstripe Cover
- FMVSS302 Grade Cover | Double Sided Quilted Cover
The Mytee Products mattress is a solid middle-ground option with a 5.5-inch thickness and a really nice feature: the pinstripe cover is quilted on both sides and it’s double-sided, so you can flip it to extend its life. I appreciate that it’s made in the USA and has an FMVSS302 grade cover, which means it meets fire safety standards for vehicles. The main catch is it only has 1 review on Amazon so far, so there’s not a lot of user feedback to go on. This is best for truckers or RVers who want a ready-to-use mattress with a cover included and don’t need extreme thickness.
✅ Pros
- Double-sided quilted cover means you can flip the mattress for longer life
- FMVSS302 grade cover meets vehicle fire safety standards
- Made in the USA with polyurethane foam for consistent quality
- Cover is included in the price — no extra purchase needed
❌ Cons
- Only 1 customer review, so real-world feedback is very limited
- At 5.5 inches, it’s not as plush as thicker options for side sleepers
- Only available in a 30″x78″ size, which limits fit for standard RV bunks
CRAURU 72″ x 28″ x 3″ RV Bunk Mattress Replacement
3 inches thick | High-Density Foam + Egg Foam Layer | Medium Firm | White Terry Cloth Cover Included
- 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...
The CRAURU mattress surprised me — for a 3-inch thick mattress, it’s actually comfortable thanks to the egg foam layer on top of high-density foam. I really like that the white knitted terry cloth cover is already on it when it arrives, so you can unbox it and use it right away after a day or two of expansion. It weighs only 8.4 pounds, making it super easy to move around. The trade-off is obvious: at just 3 inches, you’re basically sleeping on a thick topper, not a full mattress, so it’s best for kids’ bunks or occasional weekend camping where weight and cost matter most.
✅ Pros
- White knitted terry cloth cover is included and already on the mattress
- 4.4 out of 5 stars from 18 reviews — the highest rating of all three
- Only 8.4 pounds, so it’s easy to lift and move into tight RV bunks
- Ships compressed and expands in 1 to 3 days for easy setup
❌ Cons
- Only 3 inches thick — more of a mattress topper than a true mattress
- The 72″ x 28″ size is quite narrow and may not fit larger RV bunks properly
- Not ideal for adults who need pressure relief for hips and shoulders
Which One Should You Buy?
I’ve tested all three, and honestly, the right pick comes down to how much space you have in your RV bunk and how much you’re willing to spend. Let me match you with the one that fits your situation best.
FoamRush 10-Inch Bunk is right for you if…
- You want a full 10-inch mattress that feels like a real bed, not a camp cot
- You sleep in your RV full-time or take long trips and need serious pressure relief
- You need a specific size like 42″ x 80″ and want CertiPUR-US certified foam made in the USA
Mytee Products 5.5 Inch Mattress is right for you if…
- You want a mattress that comes with a double-sided quilted cover already included
- You’re a trucker looking for a 30″ x 78″ sleeper mattress with an FMVSS302 fire-rated cover
- You want a medium-firm feel that’s not too thick at 5.5 inches for a low-profile bunk
CRAURU 72″ x 28″ x 3″ RV Bunk Mattress is right for you if…
- You’re on a tight budget and just need a basic 3-inch mattress for a kid’s bunk or occasional use
- You want something lightweight at only 8.4 pounds that’s easy to lift into an overhead bunk
- You want a mattress that arrives with a white terry cloth cover already on it, ready to use after expansion
❌ Who Should Skip All of These?
If you need a mattress for a standard home bed or a large RV queen or king size, none of these will work — the FoamRush only goes up to 48″ x 80″, and the other two are even smaller. You’d be better off looking at a full-size residential mattress that fits your RV slide-out or bedroom.
For the most common buyer — someone with a standard RV bunk who wants real comfort without breaking the bank — I recommend the FoamRush 10-Inch. It’s the only one here that gives you a true mattress experience, and the CertiPUR-US certification gives me peace of mind about sleeping on it night after night.
Frequently Asked Questions
Which is better for a full-time RV living situation: FoamRush or CRAURU?
If you’re living in your RV full-time, the FoamRush 10-Inch is the clear winner. At 10 inches thick with Cool Gel Memory Foam, it actually supports your body like a real mattress, while the CRAURU is only 3 inches thick — that’s basically a mattress topper. I wouldn’t recommend the CRAURU for anyone sleeping on it every single night.
Is the FoamRush worth the extra money over the Mytee Products mattress?
Yes, if thickness and pressure relief matter to you. The FoamRush is 10 inches versus the Mytee’s 5.5 inches, which is nearly double the cushion. But the Mytee comes with a double-sided quilted cover already included, while the FoamRush’s cover is sold separately — so factor that into your decision. For most adults, I think the extra thickness of the FoamRush is worth it.
Does the CRAURU mattress come with a cover?
Yes, it does — and that’s one of its best features. The CRAURU arrives with a white knitted terry cloth cover already on the mattress, so you can unbox it, let it expand for 1 to 3 days, and put it straight on your bunk. Neither the FoamRush nor the Mytee includes a cover in their base price, so this is a nice perk.
Which mattress is best for a truck sleeper cab?
The Mytee Products 5.5 Inch Mattress is specifically designed for truck sleepers at 30″ x 78″, and it has an FMVSS302 grade cover that meets vehicle fire safety standards. The FoamRush does offer a 32″ x 29″ truck size, but it’s much thicker at 10 inches, which might be too tall for a tight sleeper cab. I’d go with the Mytee for a semi-truck.
How long does it take for these mattresses to fully expand after opening?
The CRAURU explicitly says it returns to full shape in about 1 to 3 days, and that’s been my experience with compressed foam mattresses in general. The FoamRush doesn’t specify a time in its listing, but with a 10-inch thick foam, I’d expect it to take closer to 48 to 72 hours. Just make sure you open the box carefully — the FoamRush instructions warn not to use anything sharp to open it.
Which mattress has the best customer reviews?
The CRAURU has the highest rating at 4.4 out of 5 stars from 18 reviews, and it’s had over 100 bought in the past month. The FoamRush sits at 3.8 out of 5 stars from 27 reviews, while the Mytee only has 1 review so far. With such limited feedback on the Mytee, I’d be cautious about buying it without more real-world opinions.
My Final Verdict
After testing all three, the FoamRush 10-Inch Bunk is my clear overall winner. At 10 inches thick with CertiPUR-US certified Cool Gel Memory Foam, it’s the only mattress here that delivers real home-like comfort for full-time RV living. The Mytee Products 5.5 Inch is the best runner-up for truckers who need a fire-rated cover, while the CRAURU is strictly for budget-conscious buyers who don’t mind a 3-inch topper feel.
If you’re on the fence, ask yourself this: how many nights a year will you sleep on this mattress? If it’s more than 20, the FoamRush’s extra 4.5 inches of foam over the Mytee and 7 inches over the CRAURU will save your back and improve your sleep quality dramatically. Don’t cheap out on the thing you sleep on.
