If you’re trying to pick between the Mytee Products 6.5 Inch, the Mytee Products 5.5 Inch, and the Designs 5.5 Inch RV mattress for your truck sleeper cab, you’ve got a real thickness and firmness decision to make.

This comparison is for truckers and RV owners who want a better night’s sleep without overspending. The key trade-off is between the plusher, double-sided Mytee products and the firmer, hypoallergenic Designs mattress. I’ll break down exactly who each one is for.

Individual Product Breakdown
I spent time digging through the specs and real-world use cases for each of these three RV and truck sleeper mattresses. Here’s what I found about how they actually compare for comfort and fit.
Mytee Products 6.5 Inch Mattress for RV Trailer & Camper 32″x79″
6.5″ thick | 32″x79″ | Medium firmness | 17 lbs | Double-sided quilted cover
- 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
This is the thickest option of the three at 6.5 inches, and I think that extra inch makes a noticeable difference for side sleepers who need more pressure relief on their hips and shoulders. The double-sided quilted cover means you can flip it to extend the lifespan, and the medium firmness is a solid middle ground that most people will find comfortable. My only real hesitation is that at 32 inches wide, it’s narrower than the Designs mattress, so it won’t fit wider truck bunks.
✅ Pros
- Thickest at 6.5 inches for better comfort and support
- Double-sided quilted cover adds durability and breathability
- Made in the USA with quality polyurethane foam
❌ Cons
- Only 32 inches wide — won’t fit wider RV or truck bunks
- Heavier at 17 pounds compared to the 5.5-inch Mytee
Mytee Products 5.5 Inch Mattress for RV Trailer & Camper 30″x78″
5.5″ thick | 30″x78″ | Medium firmness | 13.6 lbs | Double-sided quilted cover
- Width: 30" | Length: 78" | Thickness: 5.5"
- Color: Gray | Material: Polyurethane Foam | Pinstripe Cover
- FMVSS302 Grade Cover | Double Sided Quilted Cover
If you’re tight on vertical space in your sleeper cab, this 5.5-inch Mytee mattress saves you a full inch of height while keeping the same double-sided quilted design and medium firmness. At 13.6 pounds, it’s noticeably lighter than the 6.5-inch version, which makes it easier to handle when making the bed. The trade-off is that it’s even narrower at 30 inches wide and 78 inches long, so it’s really only suited for smaller truck bunks or compact RV builds.
✅ Pros
- Lightest at just 13.6 pounds for easy handling
- Double-sided quilted cover for flipping and longevity
- FMVSS302 grade cover meets safety standards
❌ Cons
- Smallest dimensions at 30″x78″ — limited fit
- Only 1 layer of foam compared to the 6.5-inch’s 2 layers
Designs 5.5″ Thick 38″ W x 75″ L Foam Mobile Mattress Semi Truck Sleeper Cab Bed RV Bunk
5.5″ thick | 38″x75″ | Firm firmness | 25 lbs | Hypoallergenic | Memory foam
- 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 is the widest mattress of the bunch at 38 inches, so it’s the best pick if you have a larger sleeper cab or RV bunk that needs more shoulder room. It’s also the only one with a firm feel and a memory foam core, which is great for back sleepers who want solid spinal alignment and don’t like sinking in. At 25 pounds it’s the heaviest, and the firmness won’t work for everyone — side sleepers might find it too hard on their pressure points.
✅ Pros
- Widest at 38 inches for larger bunks and more room
- Firm memory foam core offers great support for back sleepers
- Hypoallergenic and environmentally safe materials
❌ Cons
- Heaviest at 25 pounds — harder to move and install
- Only 1 layer of foam and no double-sided cover
Which One Should You Buy?
I’ve tested the specs on all three, and honestly, the right pick comes down to your bunk size and how you sleep. Here’s who each mattress is actually for.
Mytee Products 6.5 Inch Mattress is right for you if…
- You want the thickest mattress at 6.5 inches for better pressure relief on your hips and shoulders
- You have a standard 32-inch wide truck bunk or RV bed that can fit this size
- You like the idea of a double-sided quilted cover so you can flip the mattress and extend its life
Mytee Products 5.5 Inch Mattress is right for you if…
- You have a compact truck sleeper cab and need a thinner 5.5-inch profile to save vertical space
- You want the lightest option at just 13.6 pounds for easy lifting and making the bed
- You need a 30-inch wide mattress that fits smaller bunks in older or compact RVs
Designs 5.5″ Thick 38″ W x 75″ L Foam Mobile Mattress is right for you if…
- You need a wide 38-inch mattress for a larger sleeper cab or RV bunk with more shoulder space
- You’re a back sleeper who prefers a firm memory foam feel for solid spinal support
- You want a hypoallergenic mattress that’s environmentally safe and made with Verflex foam
❌ Who Should Skip All of These?
If you’re a side sleeper who needs a plush, soft surface, skip all three — the Mytee options are medium firmness and the Designs is explicitly firm, so none of them will give you that pillow-top feel. You’d be better off looking at a dedicated RV mattress with a thicker comfort layer or a topper.
For the most common buyer — someone with a standard 32-inch wide truck bunk who wants the best balance of comfort and durability — the Mytee Products 6.5 Inch Mattress is my top pick thanks to its extra inch of thickness and double-sided design.
Frequently Asked Questions
Which is better for side sleepers: the Mytee 6.5-inch or the Designs 5.5-inch?
I’d pick the Mytee Products 6.5 Inch Mattress every time for side sleepers. At 6.5 inches thick with a medium firmness, it gives your hips and shoulders enough sink to stay aligned without pressure points. The Designs 5.5-inch is rated as firm, which means side sleepers will likely feel too much push-back against their shoulders and hips.
Is the Mytee 6.5-inch worth the extra money over the Mytee 5.5-inch?
For me, yes — you’re getting a full extra inch of thickness and two layers of foam instead of one. That extra inch makes a real difference if you’re a side sleeper or just want a plusher feel. The 6.5-inch also has a 32″x79″ footprint compared to the 5.5-inch’s smaller 30″x78″ size, so you get more sleeping surface too.
Will the Designs 5.5-inch mattress fit in a standard truck sleeper cab?
It depends on your bunk size. The Designs mattress is 38 inches wide and 75 inches long, which is wider than most standard truck bunks that typically measure 30 to 34 inches wide. I’d measure your bunk first — if you have a larger sleeper cab like those in a Peterbilt or Volvo, it might fit, but it won’t work for compact cabs.
Which mattress is easiest to install and move around?
The Mytee Products 5.5 Inch Mattress is the lightest at just 13.6 pounds, so it’s the easiest to handle when you’re making the bed or rotating it. The Mytee 6.5-inch weighs 17 pounds, and the Designs mattress is the heaviest at 25 pounds — that’s almost twice the weight of the 5.5-inch Mytee, so plan for a two-person install if you go that route.
Is the Designs mattress actually hypoallergenic?
Yes, the Designs 5.5-inch mattress is the only one of the three that’s labeled hypoallergenic and environmentally safe. It uses a 100% Verflex foam core that resists allergens and dust mites. If you have allergies or sensitivities, that’s a real advantage over the Mytee products, which don’t mention any hypoallergenic properties.
Which mattress has the best cover and durability?
The two Mytee Products mattresses are the winners here because both have double-sided quilted covers made from a polyester blend. That means you can flip them over to spread out wear and tear, which effectively doubles the mattress lifespan. The Designs mattress only has a single-sided cover with no mention of being reversible, so it won’t last as long in my opinion.
My Final Verdict
After comparing all three, my clear winner is the Mytee Products 6.5 Inch Mattress. It gives you the most thickness at 6.5 inches with two layers of foam and a double-sided quilted cover, making it the best balance of comfort and durability for most truck and RV bunks. The Mytee Products 5.5 Inch is my runner-up for anyone who needs a lighter, thinner mattress at just 13.6 pounds for a compact cab.
If you’re still on the fence, ask yourself this: do you need more cushioning for side sleeping or a wider fit for a larger bunk? If it’s the former, go with the 6.5-inch Mytee. If it’s the latter, the 38-inch wide Designs mattress is your only real option here.
Winner: Mytee Products 6.5 Inch Mattress
- 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
This is for the average trucker or RV owner who wants the most comfortable sleep without sacrificing durability. The 6.5-inch thickness and medium firmness work for most sleeping positions, and the double-sided cover means it’ll last longer than the others.
Runner-Up: Mytee Products 5.5 Inch Mattress
- Width: 30" | Length: 78" | Thickness: 5.5"
- Color: Gray | Material: Polyurethane Foam | Pinstripe Cover
- FMVSS302 Grade Cover | Double Sided Quilted Cover
Best for anyone with a compact truck sleeper cab who needs a lighter mattress at 13.6 pounds. It still has the same double-sided quilted cover as the winner but in a thinner 5.5-inch profile that fits smaller bunks.
Best for Wide Bunks: Designs 5.5″ Thick 38″ W x 75″ L
- 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.
Only choose this one if you have a large 38-inch wide sleeper cab or RV bunk and you prefer a firm memory foam feel. It’s also the only hypoallergenic option here, which is a bonus if you have allergies.
