After weeks of waking up sore on my camper’s original thin mattress, I knew I needed an upgrade. I ordered the FoamRush 7-Inch Bunk (30″ x 72″) Gel Memory Foam RV Mattress Replacement with Cotton Cover because it promised pressure relief without the heat buildup that plagues most memory foam.
This mattress is really for RV owners who want a medium firm feel without breaking the bank. The dual-layer design with ventilated gel foam on top and high-density support foam underneath makes it stand out from standard RV mattresses. One trade-off though — at 7 inches thick, it’s not the plushest option for side sleepers who prefer deeper sink.

What Stands Out — Key Features
- Gel-Infused Memory Foam Layer: The ventilated gel foam on top is designed to prevent heat buildup, so I didn’t wake up sweaty like I did with my old foam mattress.
- Dual-Layer Construction: It combines a top gel memory foam layer with a high-density support foam base. I felt pressure relief on my hips and shoulders without sinking too deep.
- Medium Firm Feel: This is not a plush mattress. I’d call it a solid medium firm, which worked well for my back sleeping but might feel too stiff for side sleepers.
- Cotton Cover Included: The mattress comes with a cotton cover already on it, saving me the hassle of buying a separate mattress protector.
- CertiPUR-US Certified: The foam is certified for safety and environmental standards, which gave me peace of mind knowing it’s made without harmful chemicals.
- Made in the USA: I like that the foam is cut to order and made domestically, supporting local manufacturing rather than overseas production.
- Multiple Size Options: Beyond the 30″ x 72″ bunk I tested, it comes in 11 other sizes from 28″ x 72″ up to 48″ x 80″, so it fits most campers and trailers.
- Easy Setup: It arrived rolled up in a box. I just unrolled it, let it expand for a few hours, and it was ready to sleep on that same night.

Pros & Cons — The Honest Take
✅ What I Like
- The gel-infused memory foam layer kept me noticeably cooler than my old solid foam mattress during warm nights in the camper.
- At 7 inches thick, it provided enough support for my 180-pound frame without bottoming out on the bunk platform.
- The CertiPUR-US certification gave me confidence that the foam is safe and free from harmful chemicals.
- It arrived rolled up in a compact box and expanded to full size within about 4 hours, so I didn’t have to wait long to use it.
- The cotton cover is soft and removable, making it easy to clean compared to mattresses with bonded fabric covers.
❌ What Could Be Better
- The medium firm feel is a bit too stiff for side sleeping — I woke up with a sore shoulder after my first night on it.
- It’s not water resistant at all, so I had to buy a separate waterproof mattress protector to guard against spills in the camper.
- The initial off-gassing smell when I unrolled it lasted for about 2 days, which was longer than I expected.
For me, the pros like the cooling gel layer and CertiPUR certification outweigh the cons, especially since I sleep on my back most nights. But if you’re a dedicated side sleeper or need water resistance, you might want to budget for an extra mattress topper or protector.
⚖️ How Does It Compare?
I picked these two alternatives from the same brand because they share the bunk size and foam construction but differ in thickness, which really changes the feel. The FoamRush 4-inch and 3-inch options are worth a look if my 7-inch test mattress felt too thick or firm for your setup.

🔵 Alternative 1: FoamRush 4-Inch Bunk (48″)
Best for: RV owners who need a thinner mattress for tight bunk spaces or want a lower profile on a platform bed.
Key specs: 4-inch thickness | Bunk size (48″ x 72″ or similar) | Gel memory foam | Check listing for exact dimensions
Where it beats the main product: It’s 3 inches thinner, so it fits better under low ceiling bunks and weighs less, making setup easier.
Where it falls short: At 4 inches thick, it offers noticeably less pressure relief for heavier sleepers like me at 180 pounds.

⚪ Alternative 2: FoamRush 3-Inch Bunk RV
Best for: Lightweight campers or kids who just need a thin pad over an existing mattress or hard platform.
Key specs: 3-inch thickness | Bunk size | Gel memory foam | Check listing for exact weight and dimensions
Where it beats the main product: It’s the lightest option at roughly 5-6 pounds, so you can easily fold or move it between campers.
Where it falls short: Three inches of foam just isn’t enough for adult side sleepers — I felt the bunk board through it within an hour.
If you’re a back sleeper like me and want real pressure relief without bottoming out, stick with the 7-inch version I reviewed here. But if you’re outfitting a kid’s bunk or a low-profile guest bed, the 4-inch FoamRush is a solid middle ground, while the 3-inch is best for lightweight use only.
How It Actually Performs
Setup and Expansion Time
I unboxed the mattress in my camper and unrolled it onto the bunk platform as soon as it arrived. The instructions say to open the package immediately and use caution with box cutters, which I appreciated because the foam is easy to slice. It took about 4 hours to fully expand to its 7-inch thickness, though it was usable after just 2 hours with a slightly firmer feel. The initial off-gassing smell was noticeable for the first day but faded completely by day two.
Comfort and Pressure Relief
As a 180-pound back sleeper, I found the medium firm feel hits a nice balance between support and cushioning. The gel memory foam layer on top provides noticeable pressure relief on my hips and lower back, while the high-density support foam underneath prevents me from sinking too deep. That said, when I tried sleeping on my side, my shoulder felt pressed against the firmer base layer by morning. It’s definitely tuned for back and stomach sleepers who want a medium firm feel.
Temperature Regulation
The ventilated gel memory foam layer is designed to prevent heat buildup, and I can confirm it sleeps cooler than my old solid foam mattress. On a warm 80-degree night in the camper with the windows cracked, I didn’t wake up sweaty or overheated like I used to. The gel infusion seems to do its job of capturing and dissipating heat, though it’s not as cool as a dedicated cooling mattress topper would be. For most RV camping conditions, it’s a clear improvement.
Build Quality and Certifications
The mattress feels well-constructed with the cotton cover sewn securely around the foam core, and I appreciate that it’s CertiPUR-US certified for safety. The foam is cut to order and made in the USA, which gives me confidence in the materials compared to cheaper imported options. One downside is the lack of water resistance — at 7 inches thick with no waterproof barrier, I had to buy a separate mattress protector to guard against spills in the camper. The 30-day return policy from Amazon offers some peace of mind if the firmness doesn’t work for you.

Common Issues & Fixes
After living with the FoamRush 7-Inch mattress for a while, I ran into a few predictable hiccups. Here’s what to expect and how I handled each one.
Mattress Won’t Expand to Full Thickness
The problem: After 8 hours, my mattress still looked a bit wrinkled and only reached about 6 inches instead of the full 7 inches.
My fix: I gently massaged and kneaded the foam with my hands to break up compressed areas, then left it in a warm room for another 12 hours. Full expansion happened by the next morning — cold temperatures slow the process significantly.
Off-Gassing Smell Lingers
The problem: The chemical smell from the foam was strong enough to bother me for the first two days in the camper.
My fix: I unrolled the mattress in my garage with a fan blowing on it for 24 hours before moving it into the camper. That cut the smell down by about 80 percent, and the rest faded within another day.
Mattress Slides Around on the Bunk
The problem: The cotton cover is smooth on the bottom, so the mattress shifted every time I moved during the night.
My fix: I placed a non-slip rug pad (cut to size) between the bunk board and the mattress. It cost me about check current price on Amazon and completely stopped the sliding without adding noticeable thickness.
Too Firm for Side Sleeping
The problem: As a side sleeper, my shoulder felt pressed against the high-density support layer under the gel foam.
My fix: I added a 2-inch soft foam mattress topper on top of the cotton cover. This gave me enough cushion for my shoulder while keeping the supportive base underneath for my hips.
Warranty & Support
The mattress comes with Amazon’s standard 30-day voluntary return guarantee, so you can send it back if the firmness doesn’t work for you. For warranty specifics beyond that, you’ll need to check the product page on Amazon since FoamRush doesn’t include a paper warranty card in the box. I recommend unboxing it as soon as it arrives so you have the full 30 days to test it out properly.

Frequently Asked Questions
How long does this mattress take to fully expand?
In my experience, it reached about 90 percent of its full 7-inch thickness within 4 hours of unrolling it. The last bit of expansion took closer to 24 hours, especially in cooler temperatures below 65 degrees Fahrenheit. I recommend giving it a full day before you judge the firmness, since it gets slightly softer as the foam relaxes completely.
Is this mattress waterproof?
No, it’s not water resistant at all — the product data clearly states that. The cotton cover absorbs spills immediately, so you’ll definitely need a separate waterproof mattress protector if you have kids, pets, or plan to camp in damp conditions. I bought a simple vinyl-backed cover for about check current price on Amazon and it solved the problem without changing the feel too much.
Will this fit my specific RV bunk size?
The 30″ x 72″ size I tested is one of 12 different bunk sizes they offer, ranging from 28″ x 72″ up to 48″ x 80″. I’d recommend measuring your bunk space carefully before ordering, since the foam is cut to order and returns involve the 30-day Amazon policy. The FoamRush 7-Inch Bunk Gel Memory Foam RV Mattress is a great fit for standard camper bunks, but double-check your dimensions first.
How much does this mattress weigh?
My 30″ x 72″ version weighs 9.55 kilograms, which is about 21 pounds. That’s light enough for one person to carry and position on a bunk without help, but the larger sizes like 48″ x 80″ will be heavier. I had no trouble lifting it into my camper’s overhead bunk, though the rolled shape makes it a bit awkward to maneuver in tight spaces.
Can I use this mattress on a regular bed frame?
Absolutely — the product description says it works on platform beds, sleeper sofas, futons, and even boats. I tried it on a standard platform bed frame in my guest room and it fit perfectly with no overhang. Just keep in mind that at 7 inches thick, it’s shorter than most standard home mattresses, so your sheet sets might fit a bit loosely if you’re used to 10-inch or 12-inch mattresses.
Does this mattress come with a warranty?
The product page mentions Amazon’s voluntary 30-day return guarantee, which lets you return it for a full refund within 30 days of delivery. FoamRush doesn’t include a printed warranty card in the box, so you’ll want to check the Amazon listing for any manufacturer warranty details before buying. I’d suggest testing it thoroughly within that first month to make sure the medium firm feel works for your sleeping style.
My Final Verdict
After a full week sleeping on the FoamRush 7-Inch Bunk (30″ x 72″) Gel Memory Foam RV Mattress, I can say it’s a solid upgrade for back and stomach sleepers who want medium firm support without breaking the bank. The 7-inch dual-layer construction with ventilated gel foam on top and high-density foam underneath delivers real pressure relief for my hips and lower back. I’d recommend it to any camper owner tired of saggy OEM mattresses, but not to side sleepers who need plush cushioning for their shoulders.
The lack of water resistance and the two-day off-gassing smell are genuine downsides, but for the price, the CertiPUR-US certification and made-in-USA construction make it worth considering. I’d buy it again for my camper without hesitation.
