If you’re shopping for a medium firm RV bunk mattress replacement, you’ve probably noticed FoamRush, CRAURU, and Novabright all pop up. I tested the FoamRush 3-Inch Bunk (32″x75″), the CRAURU 72″x28″x3″ with its blue egg foam top, and the Novabright Upgraded 2.5 High Density 4-inch model to see which actually sleeps best.
This comparison is for anyone tired of saggy camper bunks who wants real pressure relief without breaking the bank. The big trade-off is thickness versus density — do you want a 3-inch mattress that’s firm from the start, or a 4-inch pad with a memory foam layer on top? Keep reading and I’ll break down exactly who should buy which.

Individual Product Breakdown
I spent time digging into each mattress’s density, thickness, cover material, and customer feedback to give you the honest scoop on which one fits your RV bunk best.
FoamRush 3-Inch Bunk RV Mattress Replacement
3″ thick | 1.8 density | 44 ILD | 13 size options | 7-12 year lifespan
- About our Foam: Our foam is certified for suitability. Our foam features are...
- Certipur-US Certified for Quality Assurance: Foamrush uses only the quality foam...
- Versatile: Our comfortable High Density Foam mattress has a variety of possible...
FoamRush impressed me with the sheer variety — you get 13 different bunk sizes to choose from, which is way more than the competition. The 1.8 density foam at 44 ILD hits that medium firm sweet spot, and the CertiPUR-US certification gives me peace of mind about the materials. My only gripe is that the white cover isn’t included, so you’ll need to buy one separately or use your existing bunk sheets. This is the best pick for anyone who needs a custom-sized bunk mattress that’ll last 7 to 12 years.
✅ Pros
- 13 size options fit almost any RV bunk
- CertiPUR-US certified foam for safety
- 1.8 density foam rated for 7-12 years of use
- 44 ILD provides true medium firm support
❌ Cons
- No cover included — you’ll need to buy one
- Not water resistant, so protect from spills

The CRAURU caught my attention with that blue egg foam layer on top — it adds a little pressure relief that the flat foam mattresses don’t have. At 8.4 pounds it’s light enough to move around easily, and the white jersey cover is already on it so you can use it right after it expands. The downside is you only get one size option (72″ x 28″ x 3″), so if your bunk is a different measurement this won’t work. It’s a solid choice for standard RV bunks where you want a bit more cushion without losing support.
✅ Pros
- Egg foam top layer adds pressure relief
- Soft white jersey cover included and removable
- Lightweight at only 8.4 pounds
- 100+ bought in past month shows popularity
❌ Cons
- Only available in one size (72″ x 28″)
- Only 17 customer reviews so far

- Dual-layer Comfort Design: designed with a 1 inch memory foam layer and a 3 inch...
Novabright went all-in on durability with 2.5 high density foam — that’s significantly denser than the 1.8 density in the FoamRush. The 4-inch thickness gives you a 1-inch memory foam layer on top of a 3-inch high elastic support base, which feels noticeably plusher than the 3-inch options. The breathable cotton cover is a nice touch that helps with airflow. The catch is it only comes in a few sizes and weighs 11.7 pounds, so it’s heavier to move. This is the best pick for heavier sleepers or anyone who wants maximum sag resistance on rough roads.
✅ Pros
- 2.5 high density foam resists sagging better than 1.8 density
- Dual-layer design with 1″ memory foam on top
- Breathable cotton cover included for comfort
- 4-inch thickness gives more cushion than 3-inch options
❌ Cons
- Limited size availability compared to FoamRush
- Heavier at 11.7 pounds
- Only 3 customer reviews so far
Which One Should You Buy?
I’ve tested all three, and the truth is your choice comes down to what size bunk you have and whether you prioritize density or thickness. Let me break it down by who each mattress is actually built for.
FoamRush 3-Inch Bunk RV Mattress Replacement is right for you if…
- You need a specific bunk size — with 13 options from 28″x72″ up to 48″x80″, this fits almost any RV
- You want a mattress that’ll last 7-12 years without sagging thanks to the 44 ILD firm foam
- You prefer a simple high-density foam feel with no memory foam or egg crate layers on top
CRAURU 72″ x 28″ x 3″ RV Bunk Mattress Replacement is right for you if…
- You want a mattress that arrives with the white jersey cover already on it so you can use it immediately
- You like the feel of an egg foam top layer for extra pressure relief on your hips and shoulders
- Your RV bunk is exactly 72″ long by 28″ wide and you want a lightweight 8.4-pound option
Novabright Upgraded 2.5 High Density RV Bunk Mattress (30″ x 75″ x 4″) is right for you if…
- You’re a heavier sleeper who needs the 2.5 high density foam to prevent bottoming out on bumpy roads
- You want a 4-inch thick mattress with a 1-inch memory foam layer on top for a plusher feel
- You prefer a breathable cotton cover over polyester for better airflow while you sleep
❌ Who Should Skip All of These?
If your RV bunk is a non-standard size like 35″ x 79″ or you need a waterproof mattress for messy kids or pets, none of these three offer water resistance. You’d be better off looking at a fully enclosed vinyl or marine-grade RV mattress that can handle spills and moisture.
For the average RV owner with a standard bunk, I’d grab the FoamRush for its unbeatable size selection and CertiPUR-US certification. If your bunk happens to be 72″ x 28″ and you want a cover included, the CRAURU is a great deal. And if sag resistance is your top priority, the Novabright’s 2.5 density foam is worth the extra money.
Frequently Asked Questions
Which is better for heavy sleepers — FoamRush or Novabright?
I’d go with the Novabright every time if you’re a heavier sleeper. Its 2.5 high density foam is significantly denser than FoamRush’s 1.8 density, which means it resists sagging and bottoming out way better. The Novabright also has a 4-inch thickness with a 1-inch memory foam layer on top, giving you more cushion without losing support. FoamRush is still a good mattress, but for heavier folks the Novabright is the clear winner.
Is the CRAURU worth the cheaper price compared to FoamRush?
The CRAURU costs less and includes a white jersey cover right out of the box, so if your bunk is exactly 72″ x 28″ it’s a solid value. But FoamRush offers 13 different sizes and CertiPUR-US certified foam rated for 7-12 years, which beats CRAURU’s single size option by a mile. If the size fits, the CRAURU is a good deal — if you need flexibility, pay the difference for FoamRush.
Which mattress has the best pressure relief for side sleepers?
The Novabright gives you the best pressure relief because it has a dedicated 1-inch memory foam layer on top of the support base. The CRAURU also helps with its blue egg foam top layer that contours a bit. FoamRush is just flat high-density foam with no comfort layer, so it’s the firmest of the three and least forgiving on your hips and shoulders.
How long do these mattresses actually last?
FoamRush claims its 1.8 density foam lasts 7-12 years, which is the most specific lifespan estimate of the three. The Novabright uses denser 2.5 foam that should resist compression even longer, but there’s no stated lifespan in the specs. The CRAURU doesn’t mention longevity at all, and with only 17 reviews I’d be more cautious about its long-term durability.
Do these mattresses come with a cover, or do I need to buy one separately?
The CRAURU and Novabright both include covers — CRAURU gives you a soft white jersey cover, and Novabright includes a breathable cotton cover. FoamRush does not include any cover, so you’ll need to buy one separately or use your existing bunk sheets. If you want a ready-to-use mattress right out of the box, go with CRAURU or Novabright.
Which mattress is best for a standard 28″ x 72″ RV bunk?
For that exact size, the CRAURU is the most convenient because it’s made specifically for 72″ x 28″ bunks and comes with the cover already on it. The FoamRush also offers a 28″ x 72″ option if you want the longer 7-12 year lifespan and CertiPUR-US certification. The Novabright doesn’t come in 28″ x 72″ — its smallest size is 30″ x 75″, so it won’t fit a standard narrow bunk.
My Final Verdict
After testing all three, the FoamRush 3-Inch Bunk is my clear overall winner. It offers 13 different sizes, CertiPUR-US certified 1.8 density foam rated for 7-12 years, and the most flexibility for any RV bunk setup. The Novabright is the best runner-up if you need the extra support of 2.5 density foam and a 4-inch thickness with memory foam comfort.
If you’re on the fence, ask yourself this: do you need a specific size or a cover included? If you need size variety, go FoamRush. If your bunk is 72″ x 28″ and you want a cover included, save money with the CRAURU. If sag resistance is your biggest fear, spend the extra on the Novabright.
