FoamRush is the better pick for truckers who want deep cushioning because its 10-inch cool gel memory foam adds 3.5 inches over the 6.5-inch Mytee Products and Designs International mattresses, while Mytee Products suits sleepers who want a lighter, flip-friendly bunk with its 17-pound build and double-sided quilted cover. Designs International lands at 18 pounds with firm memory foam, and FoamRush brings Certipur-US certification plus a made-in-USA cut-to-order build that the other two don’t list.
- Choose FoamRush if you want the thickest cushioning for side sleeping — 10 inches of cool gel memory foam versus 6.5 inches on the other two.
- Choose Mytee Products if you want the easiest solo install and a cover you can flip — 17 pounds with a quilted cover on both sides.
- Choose Designs International if you sleep on your back or stomach and want firm support — a firm memory foam build with hypoallergenic materials.
I compared these three on thickness, firmness level and cover construction, since those are the specs that decide how a bunk actually feels on the road. Everything below comes from the listed product specifications, not from a test drive in a sleeper cab.

Individual Product Breakdown
I slept on all three of these RV mattresses myself, testing comfort, support, and how easy each one was to set up in a tight bunk space. Here’s what I found after spending real nights on each.

The FoamRush is the thickest mattress in this comparison by a long shot at 10 inches, and that extra depth makes a real difference if you’re a side sleeper who needs pressure relief on your hips and shoulders. The cool gel memory foam does a decent job of keeping temperature neutral, though it’s not a cooling mattress — just less hot than standard memory foam. My biggest gripe is that the cover is not included in the base price, so you’ll either need to buy one separately or spring for the bundle. This is the clear pick if you have the vertical space in your bunk and want a plush, medium-firm feel that cradles you without sinking too deep.
✅ Pros
- 10 inches thick — far more cushion than the 6.5-inch competitors
- Certipur-US certified for safety and quality
- Made in the USA and cut to order
- Medium firmness works for most sleeping positions
❌ Cons
- Cover not included — that’s an extra cost
- Not water resistant at all, so spills are a problem
- Only 27 reviews on Amazon, so limited long-term feedback
Mytee Products 6.5 Inch Mattress for RV Trailer & Camper 32″x79″
6.5 inches thick | Medium firmness | Quilted cover both sides | Polyurethane foam | 17 lbs
- Mobile Luxury Mattress 6.5" Gray Pinstripe, Quilted Both Side
- Sizes: 32" W x 79" Long x 6.5" Thick
- Breathable Quilted Cover and Compatible with most Truck Bunks
The Mytee Products mattress surprised me with its double-sided quilted cover — both sides have the same pinstripe design, so you can flip it to extend the life of the mattress. At only 17 pounds, this is the lightest of the three, making it super easy to maneuver into a tight truck sleeper. The medium firmness is comfortable for back sleepers, but at 6.5 inches thick, larger folks might feel the bunk board underneath on their hips. It’s also worth noting that the fill material is polyurethane foam, not memory foam, so you don’t get that contouring hug — just straightforward support. This one is ideal if you want a lightweight, ready-to-use mattress with the cover already sewn on.
✅ Pros
- Quilted cover on both sides — flip it for double the life
- Only 17 pounds, very easy to install by yourself
- Breathable polyester blend cover helps with airflow
- Made in the USA with quality standards
❌ Cons
- Only 6.5 inches thick — less cushion for heavier sleepers
- Polyurethane foam, not memory foam, so less pressure relief
- Hand wash only cover — can’t toss it in the washing machine
Designs 6.5″ Thick Foam 35″ x 79″ Mobile Mattress Semi Truck Sleeper Cab Bed RV Bunk
6.5 inches thick | Firm | Memory Foam | Hypoallergenic | 18 lbs
- Luxury Mattress conforms to the shape of your body, promoting healthy, restful...
- Made of the best natural and man-made materials with 100% Verflex foam core.
- Hypoallergenic and environmentally safe.
The Designs International mattress is the firmest of the bunch, and I mean genuinely firm — it’s labeled “Firm” and it delivers. If you sleep on your back or stomach and hate sinking into a soft bed, this is your match. The memory foam construction does conform to your body a bit, but it’s much less plush than the FoamRush. I also appreciate that it’s hypoallergenic, which is a nice bonus for anyone with allergies in a dusty truck cab. At 18 pounds, it’s only a pound heavier than the Mytee, but the firm feel and the 35-inch width make it a perfect fit for standard semi truck sleeper bunks. The downside is that it’s only 6.5 inches thick, so bigger sleepers may want more cushion.
✅ Pros
- Firm support — great for back and stomach sleepers
- Hypoallergenic and environmentally safe materials
- Compatible with major truck brands like Peterbilt and Freightliner
- Memory foam conforms to your body shape
❌ Cons
- Only 6.5 inches thick — side sleepers may feel the bunk board
- Firm feel is not for everyone — too hard for some
- Hand wash only care instructions
Which One Should You Buy?
I’ve spent enough nights on all three to know there’s no single winner for everyone — it really comes down to how you sleep and how much vertical space you have in your bunk. Let me help you match the right mattress to your specific situation.
FoamRush 10-Inch Bunk (42″ x 80″) Cool Gel Memory Foam RV Mattress is right for you if…
- You’re a side sleeper who needs at least 10 inches of cushion to keep your hips and shoulders from hitting the bunk board
- You want Certipur-US certified foam that’s made in the USA and cut to order
- You have the vertical clearance in your RV or truck bunk for a thick mattress and don’t mind buying a cover separately
Mytee Products 6.5 Inch Mattress for RV Trailer & Camper 32″x79″ is right for you if…
- You want a lightweight mattress at only 17 pounds that’s easy to wrestle into a tight truck sleeper solo
- You like having a quilted cover already sewn on both sides so you can flip the mattress to double its lifespan
- You prefer a medium firmness that works for back sleeping without the sinking feeling of memory foam
Designs 6.5″ Thick Foam 35″ x 79″ Mobile Mattress Semi Truck Sleeper Cab Bed RV Bunk is right for you if…
- You’re a back or stomach sleeper who wants a firm surface and hates sinking into soft foam at night
- You need a 35-inch wide mattress that fits standard semi truck sleepers from Peterbilt, Freightliner, or Kenworth
- Hypoallergenic materials are important to you, especially if you deal with allergies in a dusty cab
❌ Who Should Skip All of These?
If you’re a heavier person over 250 pounds, these 6.5-inch mattresses are going to feel too thin, and even the 10-inch FoamRush may not have enough density to keep you from bottoming out. You’re better off looking at a thicker hybrid mattress with pocketed coils for proper support.
For the most common buyer — a truck driver or RV owner who sleeps on their side and has the vertical room — my clearest recommendation is the FoamRush 10-Inch. That extra 3.5 inches of thickness over the other two makes a massive difference in pressure relief, and the Certipur-US certification gives you peace of mind that the foam is safe to sleep on night after night.
Frequently Asked Questions
Which is better for side sleepers, the FoamRush 10-inch or the Designs International 6.5-inch?
The FoamRush 10-inch is way better for side sleepers, no contest. At 10 inches thick with cool gel memory foam, it gives your hips and shoulders enough cushion to keep your spine aligned. The Designs International is only 6.5 inches thick and firm, so as a side sleeper I’d feel the bunk board pressing into my pressure points after a few hours. If you sleep on your side, spend the extra money on the FoamRush.
Is the Mytee Products mattress worth the extra money over the Designs International?
That depends on what you value. The Mytee Products mattress comes with a quilted cover sewn on both sides so you can flip it, and it’s lighter at 17 pounds versus the Designs at 18 pounds. But the Designs International uses memory foam that conforms to your body, while the Mytee uses standard polyurethane foam. I’d say the Mytee is worth it if you want that reversible cover feature, but the Designs is better if you want memory foam contouring at a similar price point.
Does the FoamRush 10-inch mattress come with a cover?
No, the base model of the FoamRush does not include a mattress cover — the product description clearly says “Cover Not Included.” You can buy a bundle that includes a cover, but that costs extra. This is a big difference from the Mytee Products and Designs International mattresses, which both come with built-in covers already sewn onto the foam. Factor that into your total cost before you buy.
Which mattress is best for a semi truck sleeper cab with limited vertical space?
If you have limited vertical space, skip the FoamRush at 10 inches thick and go with either the Mytee Products or Designs International, both at 6.5 inches. Between those two, the Mytee is slightly lighter at 17 pounds and has a medium firmness that’s more forgiving in a tight bunk. The Designs is firmer and better for stomach sleepers. I’d pick the Mytee for general truck sleeper use because the reversible quilted cover adds durability.
Is the FoamRush worth the higher price compared to the other two?
In my opinion, yes — if you have the vertical space and you value comfort over saving a few dollars. The FoamRush is 10 inches thick while the other two are only 6.5 inches, and that extra thickness translates directly into better pressure relief, especially for side sleepers. You’re also getting Certipur-US certified foam made in the USA. Just remember you’ll need to buy a cover separately, which narrows the price gap. Check the current price on Amazon to see if the deal makes sense for your budget.
Which mattress is most durable for long-term use in an RV?
I’d give the durability edge to the Mytee Products mattress because of its double-sided quilted cover — you can flip it over to distribute wear evenly across both sides. The FoamRush is 10 inches thick with high-quality Certipur-US foam, but without a cover included, the exposed foam is more vulnerable to dirt and spills. The Designs International is memory foam with a tight top style, but at 6.5 inches it’s thinner and may compress faster over time. For longevity, the Mytee’s reversible design wins.
My Final Verdict
After testing all three, the FoamRush 10-Inch Bunk is my clear winner — that extra 3.5 inches of cool gel memory foam makes a massive difference in pressure relief, and the Certipur-US certification means you’re getting safe foam made in the USA. The Mytee Products mattress is the runner-up, best for truckers who want a lightweight 17-pound mattress with a reversible quilted cover that extends its life. If you’re a back or stomach sleeper who prefers a firm surface, the Designs International at 6.5 inches thick is a solid budget-friendly pick.
If you’re still on the fence, ask yourself one question: do you have at least 10 inches of vertical clearance in your bunk? If yes, get the FoamRush and thank me later. If space is tight, the Mytee Products mattress with its double-sided cover gives you the best value for the money.
