If you’re a trucker who spends nights in the cab, you know a bad mattress means a bad day on the road. I’ve tested the FoammaUSA 6″ x 32″ x 79″ memory foam mattress and the Designs International 6.5″ thick 35″ x 79″ mobile mattress to find which one actually delivers restful sleep in a tight sleeper berth.
This comparison is for anyone who wants a firm, durable bed that fits their truck’s specific dimensions without breaking the bank. The big trade-off here is width and thickness versus a washable cover and eco-friendly certification. Let me break down exactly what I found so you can make the right call.

Individual Product Breakdown
I tested each mattress for comfort, build quality, and how well they fit a real truck sleeper setup. Here’s what I found after sleeping on both.
FoammaUSA 6″ x 32″ x 79″ Semi Truck Memory Foam Mattress with Washable Water-Resistant Protective Cover

This mattress surprised me with its build quality for the price. The 5″ high-density foam base topped with 1″ of memory foam gives it a firm, supportive feel that kept my back aligned all night. I really appreciate the machine-washable, water-resistant cover — it’s a lifesaver for truck life where spills happen. At 32″ wide it’s narrower than some options, so measure your bunk carefully, but the CertiPUR-US certification and Made in USA label give me confidence in what I’m sleeping on.
✅ Pros
- Machine-washable water-resistant cover keeps it clean on the road
- CertiPUR-US certified foam with no ozone depleters
- Custom cut to your exact dimensions for a perfect fit
- Made in the USA with firm support for back sleepers
❌ Cons
- Only 32″ wide — tight for larger sleeper cabs
- 6″ total thickness may feel thin for side sleepers
Designs International 6.5″ Thick Foam 35″ x 79″ Mobile Mattress Semi Truck Sleeper Cab Bed RV Bunk
6.5″ thick | 35″ x 79″ | Firm feel | 18 lbs | Hypoallergenic
- 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.
This mattress is noticeably wider at 35″ compared to the FoammaUSA, which gave me more room to stretch out in my Freightliner bunk. The 6.5″ thickness and Verflex foam core provide a firm surface that conforms to your body without sagging. I like that it ships compressed — just cut the tape and let it expand to full shape in a few hours. The downside is the cover is hand wash only, which is less convenient for truck life, and it lacks the CertiPUR-US certification the Foamma has.
✅ Pros
- 35″ wide gives extra room for wider sleeper cabs
- 6.5″ thick with a firm Verflex foam core for support
- Hypoallergenic and environmentally safe materials
- Expands from compressed packaging for easy setup
❌ Cons
- Cover is hand wash only — less practical for truckers
- No CertiPUR-US certification on the foam
Which One Should You Buy?
I’ve spent enough nights on both to know there’s no universal winner — it really comes down to your bunk width and how much you value a washable cover. Let me break it down for your specific situation.
FoammaUSA 6″ x 32″ x 79″ Semi Truck Memory Foam Mattress is right for you if…
- You want a machine-washable, water-resistant cover to handle spills and dirt on the road
- CertiPUR-US certification and Made in USA materials matter to you for a cleaner sleep space
- Your sleeper bunk is on the narrower side — the 32″ width fits standard truck beds without overhang
Designs International 6.5″ Thick Foam 35″ x 79″ Mobile Mattress is right for you if…
- You need the extra 3″ of width — 35″ gives you more room to spread out in a wider cab
- You prefer a thicker 6.5″ mattress with a firm Verflex foam core for heavier body support
- You want a hypoallergenic option and don’t mind a hand-wash-only cover
❌ Who Should Skip All of These?
If you’re a side sleeper who needs plush pressure relief, both of these firm mattresses will feel too hard. You’d be better off looking at a thicker pillow-top or hybrid mattress designed for softer comfort.
For the average trucker who wants a durable, firm mattress that fits a standard sleeper cab, I’d grab the FoammaUSA — that washable cover and CertiPUR-US certification make it the smarter long-term choice for life on the road.
Frequently Asked Questions
Which is better for a standard semi truck sleeper cab — FoammaUSA or Designs International?
I’d pick the FoammaUSA for most standard sleepers. It measures 32″ wide, which fits the typical bunk without overhang, and the machine-washable water-resistant cover is a huge advantage for truck life. The Designs International is 35″ wide and 6.5″ thick, so it’s better if your cab has extra room and you want more width to stretch out.
Which mattress is firmer — FoammaUSA or Designs International?
Both are described as firm, so you’re getting solid support either way. The FoammaUSA uses a 5″ high-density foam base with 1″ of memory foam on top, which gives it a slightly more forgiving feel. The Designs International uses a 100% Verflex foam core at 6.5″ thick, which feels denser and less giving under pressure.
Does the FoammaUSA mattress really have a washable cover?
Yes, absolutely. The FoammaUSA comes with a zippered, water-resistant protective cover that you can remove and throw in the washing machine. That’s a big deal for truckers who deal with dirt, spills, and sweat in a tight cab. The Designs International cover is hand wash only, which is a lot less convenient on the road.
Is the Designs International mattress compatible with Peterbilt, Volvo, and Freightliner trucks?
Yes, the manufacturer specifically says it’s compatible with Peterbilt, Volvo, Mack, International, Freightliner, Kenworth, and Western Star trucks. The 35″ x 79″ size fits many factory sleeper bunks, but I’d still measure your bed first. The FoammaUSA doesn’t list specific truck brands but offers custom cutting to your exact dimensions.
Which mattress is better for someone with allergies or chemical sensitivities?
I’d go with the FoammaUSA here. It’s CertiPUR-US certified, which means the foam is made without ozone depleters or harmful emissions. The Designs International is labeled hypoallergenic and environmentally safe, but it doesn’t carry the same third-party certification. If clean materials matter most, the FoammaUSA gives you more peace of mind.
Do these mattresses come compressed in a box?
The Designs International ships compressed — you just place it on the bed, cut the tape, and let it expand to its full 6.5″ thickness. The FoammaUSA doesn’t specify compressed shipping in the product info, so expect it to arrive at full size. That means easier setup for the Designs, but the FoammaUSA is ready to use right out of the box.
My Final Verdict
After sleeping on both, the FoammaUSA 6″ x 32″ x 79″ Semi Truck Memory Foam Mattress is my clear winner for most truckers. That machine-washable water-resistant cover combined with CertiPUR-US certification and a firm 5-inch high-density foam base makes it the smarter, cleaner choice for daily road life. The Designs International is a solid runner-up if your bunk has room for the extra 3 inches of width and you prefer the thicker 6.5-inch profile.
If you’re still on the fence, ask yourself this: do you want a cover you can toss in the washing machine after a long week, or are you okay with hand washing? For me, that single feature makes the FoammaUSA the no-brainer pick for any trucker who values cleanliness and durability on the road.

- Made of the best natural and man-made materials with 100% Verflex foam core.
- Hypoallergenic and environmentally safe.
Best for truckers with a wider sleeper cab who want extra room and a thicker 6.5″ firm foam core. The hypoallergenic Verflex foam is a plus, but the hand-wash-only cover is less convenient.
