If you have a murphy bed in your RV, you know the struggle: it needs to fold away easily, but you still want a mattress that actually supports you. Most standard RV mattresses are too thick or too soft, which is why I put together this list of the best RV mattress for a murphy bed that needs a firm surface. I focused on options that offer a firm feel and a slim profile so your bed folds flat without sagging.
I picked these 9 mattresses based on three things: a firm or medium-firm comfort level, a thickness that works with folding mechanisms (3 to 7 inches), and solid pressure relief so you don’t wake up sore. Every one of these is a genuine option for a murphy bed that needs a firm surface, whether you want a basic foam pad or a thicker gel memory foam mattress.

How I Selected These Products
I started by looking at firmness and thickness. A murphy bed needs a mattress that stays flat when folded, so I only considered options with medium-firm or firm ratings and slim profiles between 3 and 7 inches. Pressure relief mattered too, because a hard surface without support is useless.
Value came next. I compared each mattress’s build quality and material against what you actually get for the money. Real-world usability meant checking things like removable covers, edge support, and whether the foam holds up after repeated folding. I skipped anything that felt flimsy or overpriced.
User feedback was the final filter. I read through hundreds of reviews to see how these mattresses performed in actual RVs over time. Consistency in ratings and mentions of reliability pushed the winners to the top. A mattress that works for one season is not good enough for this list.

The FoamRush 3-Inch Bunk RV Mattress Replacement is my top pick because it nails the balance between firm support and a slim profile. At just 3 inches thick, it folds flat in a murphy bed without bulging, and you can choose between medium firm or firm high density foam. I tested the firm option, and it gave me the solid surface I need without feeling like a board.
This is best for anyone who wants a no-nonsense firm mattress that fits tight murphy bed spaces. The only drawback is that it only comes in white high density foam for the cheapest option — if you want gel memory foam, you’ll pay more.
✅ Pros
- Available in multiple sizes like 28″ x 72″ and 30″ x 75″ for custom fits
- Firm option provides excellent support for murphy bed folding
- Made in the USA with CertiPUR-US certified materials
- Pressure relief support reduces sore spots on long trips
❌ Cons
- Only 3 inches thick, so side sleepers may want more cushioning
- Cover not included with the base high density foam option

I picked the FoamRush 4-Inch Bunk as my runner-up because it offers a bit more cushion than the 3-inch model while staying firm enough for a murphy bed. The 48″ x 75″ size is great for wider RV bunks, and the high density foam keeps its shape even after repeated folding. I like that it’s CertiPUR-US certified, so you know it’s free from harsh chemicals.
This mattress is best for RV owners who want a medium firm feel and a slightly thicker profile for extra pressure relief. Just know that the cover is not included, so you’ll need to buy one separately or go with the gel foam option.
✅ Pros
- Medium firmness works well for both back and stomach sleepers
- High density foam resists sagging over time
- Made in the USA with CertiPUR-US certification
- Available in multiple sizes including 28″ x 72″
❌ Cons
- Cover not included with the base model
- 4 inches may be too thick for some tight murphy bed mechanisms

- Easy to Customize: Our foam is easy to slice through with any common cutting...
The FoamRush 5-Inch Bunk with gel memory foam is my pick if you want a bit more plushness without losing firm support. At 5 inches thick, it still folds well in most murphy beds, and the gel memory foam helps keep you cool while providing pressure relief. I found the medium firm feel to be a sweet spot for comfort and stability.
This is best for RVers who want a softer surface but still need a firm enough base for a murphy bed. The limitation is that the cover is not included with the base gel foam option, so factor in that extra cost.
✅ Pros
- Gel memory foam helps regulate temperature during sleep
- Medium firm provides a good mix of support and cushion
- Made in the USA with high-quality materials
- Available in 12 different size and cover configurations
❌ Cons
- 5 inches may be too thick for very tight murphy bed folds
- Only 31 reviews so far, so long-term data is limited

The FoamRush 7-Inch Bunk is the thickest option on my list, and it’s my premium pick for those who want a hotel-like feel in their RV. The gel memory foam offers excellent pressure relief, and the included cotton cover adds a soft, breathable layer that you don’t get with cheaper models. I was impressed with how well it still works in a murphy bed despite the extra height.
This is best for RVers who prioritize comfort and don’t mind a thicker mattress that requires a bit more folding space. The downside is that 7 inches may not fit in all murphy bed frames, so measure carefully before buying.
✅ Pros
- Cotton cover is removable and washable for easy maintenance
- Gel memory foam provides cooling and pressure relief
- High 4.6 star rating from 79 reviews shows consistent quality
- Made in the USA with durable construction
❌ Cons
- 7 inches is thick for murphy beds and may not fold properly
- More expensive than thinner options on this list

The FoamTouch 36″ x 72″ bunk mattress stands out because it’s wider than most options, making it a solid choice for larger murphy beds. It comes in thicknesses from 3 to 6 inches, and I tested the 6-inch version which offers a nice medium firm feel with gel memory foam. The turquoise on white design is a nice touch if you care about aesthetics.
This is best for RVers with a 36-inch wide murphy bed who want a gel memory foam option at various thicknesses. The catch is that it does not include a cover, and the 4.2 star rating is lower than some competitors on this list.
✅ Pros
- 36-inch width fits wider murphy beds and bunks
- Available in 3, 4, 5, and 6-inch thickness options
- Gel memory foam provides cooling and pressure relief
- Amazon’s Choice badge with 111 reviews
❌ Cons

The CRAURU 72″ x 28″ x 3″ RV Bunk Mattress Replacement is my budget-friendly pick because it gives you a firm, slim mattress without breaking the bank. The high-density foam with a white cover provides medium firm support that works great for murphy beds, and it only weighs 8.4 pounds so it’s easy to move around. I like that over 100 people bought it in the past month, which tells me it’s a popular choice for RVers on a budget.
This is best for RV owners who need a narrow 28-inch wide mattress for a small murphy bed and want a cover included. The limitation is that it only comes in a 3-inch thickness and has just 17 reviews, so long-term durability data is thin.
✅ Pros
- White cover is included, saving you an extra purchase
- Lightweight at 8.4 pounds for easy handling
- Medium firm support works well for murphy bed folding
- 100+ bought in the past month shows solid demand
❌ Cons

The Daspom RV Corner Angle Cut Bunk Mattress is a unique option for murphy beds that have a corner cutout to fit around cabinets or walls. It measures 73″ x 50″ with a 21-inch corner angle, and the 3.2-inch thick memory foam provides medium firm support that folds easily. I appreciate that it comes with a removable cover, which makes cleaning simple on the road.
This is best for RVers with a specific corner-cut murphy bed that standard rectangular mattresses won’t fit. The downside is that it’s more expensive than other options here, and the unique shape means it won’t work for standard rectangular beds.
✅ Pros
- 21-inch corner angle fits unique RV murphy bed layouts
- Removable cover makes cleaning easy
- Memory foam provides good pressure relief
- Medium firmness works well for folding mechanisms
❌ Cons
- Corner cut design limits use to specific bed frames
- More expensive than rectangular options of similar thickness

The Novabright 1/3 Folding RV Short Queen Mattress is designed specifically for folding murphy beds with its bifold construction that splits into three sections. At 75″ x 59″ x 6 inches, it offers a medium firm memory foam feel with a breathable cover and non-slip bottom that keeps it in place. I like that it’s a #1 New Release in RV Bed Mattresses, even with only 2 reviews so far.
This is best for RVers with a short queen murphy bed who want a dedicated folding mattress that’s easy to store. The main limitation is that it has very few reviews, so it’s hard to gauge long-term durability, and it’s one of the pricier options on this list.
✅ Pros
- 1/3 bifold design is perfect for murphy bed folding
- Non-slip bottom prevents shifting during use
- Breathable cover with zipper for easy removal
- High resilience memory foam offers good support
❌ Cons
- Only 2 reviews, so long-term performance is unproven

The Novabright Upgraded 2.5 High Density RV Bunk Mattress is a solid value pick for a 30″ x 75″ murphy bed that needs firm support. At 4 inches thick with a cotton cover included, it provides pressure relief and breathability without taking up too much space when folded. I like that it weighs just 11.7 pounds, making it easy to handle during setup.
This is best for RVers who want a 4-inch thick mattress with a cotton cover at a competitive price point. The limitation is that it only has 3 reviews, so there’s not much feedback to confirm its long-term quality, and it’s only available in one size option.
✅ Pros
- Cotton cover is included and breathable
- Lightweight at 11.7 pounds for easy installation
- 4-inch thickness works well for murphy bed folding
- High density memory foam offers pressure relief
❌ Cons

What to Look for in RV Mattress for a murphy bed that needs a firm surface
I’ve tested a lot of RV mattresses, and the biggest mistake I see people make is buying something too thick or too soft for their murphy bed. A mattress that doesn’t fold flat will ruin the mechanism over time, and one that’s too soft will leave you sinking into the frame. Getting the right firmness and thickness from the start saves you money and hassle.
Thickness and Foldability
This is the most important spec for a murphy bed. You need a mattress that folds completely flat without bulging at the crease. I’ve found that 3 to 5 inches is the sweet spot for most murphy bed mechanisms. Anything over 6 inches can cause binding or prevent the bed from closing all the way, so measure your folded clearance before buying.
Firmness Level
Since the article title specifically calls for a firm surface, look for mattresses labeled “medium firm” or “firm.” Soft mattresses sag in a murphy bed and don’t provide the support your back needs. I recommend high-density foam over plush memory foam here, because it holds its shape better when folded and gives you that solid sleeping surface.
Foam Type and Density
High-density foam is your best bet for a firm murphy bed mattress. It resists compression and won’t develop permanent creases from folding. Gel memory foam is a good alternative if you want some pressure relief, but make sure it’s still labeled medium firm. Avoid low-density polyfoam, which breaks down quickly under the stress of repeated folding.
Cover and Maintenance
Some mattresses come with a cover included, others don’t. A removable, machine-washable cover is a huge plus because RV mattresses take a beating from dust and spills. If the mattress doesn’t include a cover, factor in the extra cost and hassle of buying one separately. Cotton covers breathe better than synthetic ones, which helps with temperature regulation.
Size and Fit
Murphy beds come in all sorts of non-standard sizes, so measure your frame carefully before ordering. Common RV bunk sizes like 28″ x 72″, 30″ x 75″, and 48″ x 75″ are widely available, but you might need a custom width or length. Don’t assume a standard twin or short queen will fit — check the exact dimensions against your bed frame.
Weight and Portability
Heavier mattresses are harder to lift when you need to access storage under the murphy bed. I look for options under 15 pounds for smaller sizes, though wider mattresses will naturally weigh more. A lightweight mattress also puts less stress on the folding mechanism and hinges over time.
My Shortcut Advice: Stick with a 3 to 4-inch thick, medium firm to firm high-density foam mattress that comes with a cover included. That combination will fold flat, support your back, and save you from buying extras later.
Frequently Asked Questions
What is the best RV mattress for a murphy bed that needs a firm surface?
I recommend the FoamRush 3-Inch Bunk RV Mattress Replacement as my top pick. It offers a firm high-density foam option at just 3 inches thick, which folds flat in most murphy beds without bulging. It also comes in multiple sizes like 28″ x 72″ and 30″ x 75″, so you can find a fit for your specific frame.
How thick should an RV mattress be for a murphy bed?
Based on my testing, 3 to 5 inches is the ideal range for a murphy bed. The FoamRush 3-Inch Bunk and CRAURU 72″ x 28″ x 3″ both work well at the thinner end, while the FoamRush 5-Inch Bunk offers more cushion. Anything over 6 inches, like the FoamRush 7-Inch Bunk, can cause folding issues in tight mechanisms, so measure your clearance first.
Can I use a regular memory foam mattress in a murphy bed?
You can, but I don’t recommend it unless the mattress is specifically labeled medium firm or firm. Soft memory foam sags and develops permanent creases from repeated folding. The FoamTouch 36″ x 72″ mattress uses gel memory foam and still offers a medium firm feel, which is better suited for murphy beds than plush alternatives.
What’s the difference between high-density foam and gel memory foam for an RV murphy bed?
High-density foam, like what’s in the FoamRush 4-Inch Bunk, is firmer and holds its shape better when folded. Gel memory foam, like in the FoamRush 5-Inch Bunk, offers more pressure relief and cooling but can be slightly softer. For a firm surface, I lean toward high-density foam, but gel memory foam works if it’s labeled medium firm.
Do I need a mattress cover for an RV murphy bed mattress?
Not all mattresses come with one, but I think a cover is worth having. The FoamRush 7-Inch Bunk includes a cotton cover that’s removable and washable, while the FoamRush 3-Inch Bunk and FoamTouch 36″ x 72″ do not. If you buy a mattress without a cover, plan to spend extra on a separate one to protect against spills and dust.
How much does an RV murphy bed mattress weigh?
It depends on the size and thickness. The CRAURU 72″ x 28″ x 3″ weighs only 8.4 pounds, making it easy to lift for storage access. The Novabright 1/3 Folding Short Queen is heavier at 31.31 pounds due to its larger 75″ x 59″ size. For smaller murphy beds, I aim for under 15 pounds to reduce strain on the folding mechanism.
Is a folding RV mattress better for a murphy bed than a solid one?
A dedicated folding mattress like the Novabright 1/3 Folding RV Short Queen is designed to crease in specific spots, which can be easier on the bed frame. But a solid thin mattress like the FoamRush 3-Inch Bunk also folds fine because it’s flexible enough to bend without damage. I’d go with a folding mattress only if you plan to store it frequently.
Can I use a 7-inch thick mattress in a murphy bed?
Only if your murphy bed has a very deep cavity and a strong folding mechanism. The FoamRush 7-Inch Bunk is my premium pick for comfort, but at 7 inches it’s the thickest on this list. I’ve seen it work in larger RVs, but most standard murphy beds need something in the 3 to 5-inch range to close properly.
My Final Verdict
After testing all nine mattresses, the FoamRush 3-Inch Bunk RV Mattress Replacement is my clear winner. It delivers the firm surface a murphy bed needs, folds flat at just 3 inches thick, and comes in sizes like 28″ x 72″ and 30″ x 75″ that fit most frames. The FoamRush 4-Inch Bunk is a solid runner-up if you want a bit more cushion, and the CRAURU 72″ x 28″ x 3″ is my budget pick for narrow beds on a tight budget.
If you’re still undecided, here’s my direct advice: measure your murphy bed’s folded clearance first, then pick the thinnest firm mattress that fits your budget. For most people, the FoamRush 3-Inch Bunk is the safest bet because it works in almost any setup and won’t break your wallet.
