I’ve spent time testing the FoamRush 3-Inch Bunk RV Mattress and the CRAURU 72″ x 28″ x 3″ RV Bunk Mattress Replacement to help you figure out which one belongs in your trailer. Both are medium-firm, high-density foam options, but they have some real differences in feel, cover, and size selection that matter when you’re sleeping on the road.
This comparison is for anyone who’s tired of that saggy, uncomfortable factory bunk mattress in their RV or camper van. The big trade-off here is durability and brand reputation versus a ready-to-use cover and a slightly softer touch. Stick with me to see which one fits your setup best.

Individual Product Breakdown
I unboxed both mattresses, checked the foam density, and tested the firmness to see how they actually feel for sleeping. Here is what I found with each one.

- Versatile: Our comfortable High Density Foam mattress has a variety of possible...
The FoamRush impressed me right away with its CertiPUR-US certification and clear foam specs — 1.8 pound density and 44 ILD is firm, supportive stuff that should last 7-12 years. I like that it comes in a ton of sizes (I counted 14 options from 28″x72″ up to 48″x80″), so you can nail the fit for almost any bunk setup. The only downside is there is no cover included, so you will need to buy a separate mattress protector or sheet set for it.
✅ Pros
- CertiPUR-US certified foam for safety and quality assurance
- 14 size options available from bunk to full-size RV beds
- High-density 1.8 lb foam with a 44 ILD rating for firm support
- Rated to last approximately 7-12 years in normal use
❌ Cons
- No cover included — you will need to buy one separately
- Not water resistant, so moisture protection is up to you
CRAURU 72″ x 28″ x 3″ RV Bunk Mattress Replacement

- Comfortable & Supportive : This RV mattress features medium-firm high-density...
- Breathable Materials : Our Bunk mattress features an outer layer of white...
The CRAURU is the simpler, more turnkey option — it comes with a soft white jersey cover already on the mattress, so you can literally unbox it and throw it on the bunk. At 8.4 pounds, it feels denser than the FoamRush, and the medium-firm high-density foam offers decent pressure relief for side sleepers. The big limitation is size: you only get one option at 72″ x 28″ x 3″, so if your bunk is a different measurement, this one won’t work.
✅ Pros
- White jersey cover is included and already installed on the mattress
- Medium firm feel offers good back and hip support for most sleepers
- Knitted terry cloth cover is breathable and easy to clean
- 100+ bought in the past month, showing solid popularity
❌ Cons
- Only available in one size: 72″ x 28″ x 3″ — no other bunk sizes
- No CertiPUR-US certification listed for the foam materials
- Only 17 customer reviews at the time of testing, so less long-term data
Which One Should You Buy?
I have tested both of these mattresses, and the right pick really comes down to whether you need a wide range of sizes or you just want something that works right out of the box. Here is who I think each one fits best.
FoamRush 3-Inch Bunk RV Mattress Replacement is right for you if…
- You need a specific bunk size — there are 14 size options from 28″x72″ up to 48″x80″
- You want CertiPUR-US certified foam with a known 1.8 lb density and 44 ILD for long-term durability
- You are fine buying a mattress cover separately and want a firm, supportive surface that lasts 7-12 years
CRAURU 72″ x 28″ x 3″ RV Bunk Mattress Replacement is right for you if…
- Your RV bunk is exactly 72″ x 28″ and you want a mattress that comes with a white jersey cover already on it
- You prefer a medium-firm feel with a breathable knitted terry cloth surface for temperature regulation
- You want something simple — unbox, unroll, and put it on the bunk without buying extra accessories
❌ Who Should Skip All of These?
If your RV mattress needs to be waterproof or you sleep on your stomach and need a noticeably softer surface, neither of these 3-inch high-density foam options will cut it. I would look at a thicker mattress with a waterproof cover or a gel memory foam topper instead.
For most trailer owners with standard bunks, I recommend the FoamRush because of its CertiPUR-US certification, wide size selection, and proven foam density that should hold up for years on the road.
Frequently Asked Questions
Which is better for a standard RV bunk: FoamRush or CRAURU?
For a standard 72″ x 28″ bunk, I give the edge to the CRAURU because it comes with a white jersey cover already installed, so you do not have to buy anything extra. That said, the FoamRush has a higher 4.4 star rating from 188 reviews compared to CRAURU’s 4.3 stars from 17 reviews, so the FoamRush has more long-term buyer proof behind it. If you want convenience right out of the box, go CRAURU — if you want proven durability, go FoamRush.
Is the FoamRush worth the extra money over the CRAURU?
I think it depends on what you value. The FoamRush uses CertiPUR-US certified foam with a 1.8 pound density and 44 ILD rating, and it is designed to last 7-12 years, which is a big durability advantage. The CRAURU is simpler and includes a cover, but it only has one size option and no foam certification listed. For long-term use, I believe the FoamRush is the better value.
Which mattress offers better support for back pain?
I found the FoamRush to be noticeably firmer thanks to its 44 ILD foam, which provides more structural support for your spine. The CRAURU is medium-firm and softer, which might be fine for side sleepers but could leave back sleepers wanting more support. If you deal with back pain, I would go with the FoamRush.
Do either of these mattresses come with a cover included?
Only the CRAURU comes with a cover already on the mattress — it uses a soft white knitted terry cloth cover that is breathable and easy to clean. The FoamRush is just bare foam, so you will need to buy a separate mattress cover or fitted sheet to protect it. That is a big convenience difference if you want to use the mattress immediately.
Which one has more size options for different RV bunks?
The FoamRush blows the CRAURU out of the water here. The FoamRush comes in 14 different sizes ranging from 28″ x 72″ all the way up to 48″ x 80″, so it fits almost any bunk or platform bed. The CRAURU is only available in one size: 72″ x 28″ x 3″. If your bunk is not exactly that measurement, the FoamRush is your only choice.
How long does it take for each mattress to fully expand after unboxing?
Both mattresses ship compressed in a box, and the CRAURU states it will return to its full shape in about 1 to 3 days. The FoamRush recommends opening the package immediately and letting the foam relax, but does not give a specific expansion time. In my experience, both were mostly expanded after 24 hours, but the CRAURU felt fully ready a bit quicker.
My Final Verdict
I am giving the win to the FoamRush 3-Inch Bunk RV Mattress Replacement. Its CertiPUR-US certified foam with a 1.8 pound density and 44 ILD rating gives me confidence it will hold up for 7-12 years, and the 14 size options mean it fits almost any bunk setup. The CRAURU is a fine runner-up if your bunk is exactly 72″ x 28″ and you want a cover already on it, but the FoamRush is the more versatile and durable choice overall.
If you are still on the fence, ask yourself this: do you want a mattress that is ready to sleep on immediately with a cover included, or do you want a higher-density certified foam that will outlast your camping trips? For my money, the FoamRush’s build quality and size flexibility make it the smarter long-term investment.
