Finding a double bunk mattress with a cut corner is mostly a fit problem: the length, width, thickness, and angle all need to match your RV’s bunk. A mattress that is close in size can still leave a gap or overlap the bed frame if its angled corner is on the wrong side. The options below range from full foam mattresses to a shaped topper, so check your bunk measurements and corner orientation before choosing.

Our Picks: Best Rv Double Bunk Mattress With Cut Corner reviews
1. Camping World Cozyway: A Clearly Specified 21-Inch Right Cut
This 73-by-50-inch foam mattress is made for an RV bunk with a 21-inch right corner angle. Its 4-inch build uses two layers of memory foam and has a medium firmness description. That combination makes it a straightforward replacement option when your original bunk mattress has similar measurements and the same corner orientation.
The mattress is shipped compressed. The product information recommends letting it expand for a few hours after unboxing before use. Its foam is listed as CertiPUR-US certified, and the construction is described as breathable. Some owners report a close fit and a more comfortable sleep than their original RV mattress, while others note that the angle needs to be checked carefully even when the overall measurements seem right.
The main limitation is that “right corner” must match your bunk as viewed from the correct side. A mattress with the right overall length and width can still be wrong if the cut faces the opposite direction. Its 4-inch thickness may also be less cushioning than the thicker option below.
Pros:
- Lists a specific 73-by-50-inch size and 21-inch right cut.
- Four-inch, two-layer memory foam construction.
- Medium firmness and CertiPUR-US certified foam.
- Compressed shipping can make delivery and setup easier.
Cons:
- The specified right-side angle may not match every RV bunk.
- At 4 inches thick, it is not the thickest choice here.
Verdict: Choose this one if your bunk measures about 73 by 50 inches and needs a 21-inch cut on the right; confirm the orientation before ordering.
2. Camping World Cozyway Curved Mattress for Double-Over-Double Bunks
This Cozyway mattress measures 74 by 50 inches and is described as a curved bunk mattress for double-over-double RV bunks. It is 4 inches thick and made with high-density foam. The curved design is intended to fit a bunk shape that is not a standard rectangle, while the compressed packaging is designed to simplify transport and setup.
Its key difference from the other picks is that the product details do not give a specific corner angle or state whether the cut is on the left or right. That makes it harder to verify a match from dimensions alone. Some owners report a good fit in their camper, but the shaped edge still needs to be compared with your bed frame before you buy.
This is a reasonable candidate if your RV has a curved double-over-double bunk and the mattress profile matches the listed shape. If your bunk has a defined 21- or 22-inch angle cut, one of the options with a stated corner measurement may be easier to assess.
Pros:
- 74-by-50-inch size designed for double-over-double bunk use.
- Four-inch high-density foam construction.
- Curved shape can suit some non-rectangular RV bunks.
- Compressed for easier transport and storage before setup.
Cons:
- Product details do not specify the cut angle or its left/right orientation.
- Exact shape compatibility is harder to confirm without comparing the bunk profile.
Verdict: Consider this mattress when you have a curved double-over-double bunk that matches its shape, but verify the outline with the seller’s product images and your measurements first.
3. Kistrba Corner-Cut Topper for an Existing RV Mattress
Despite “mattress” in the listing title, the supplied product details describe this as a 3.2-inch mattress topper. It measures 74 by 51 inches and has a 21-inch right corner angle cut. Its two foam layers pair memory foam on top with support foam below, and a zippered knitted cover is described as removable and machine washable.
This pick is best viewed as a way to add cushioning to a correctly sized corner-cut mattress you already own, rather than as a complete replacement mattress. Its pre-shaped edge avoids having to fold or trim a rectangular topper, but the topper dimensions and cut still need to line up with your bunk. The stated right-side cut is especially important to verify.
The removable cover is a practical feature for keeping the topper clean between trips. On the other hand, if the existing mattress is worn out or lacks support, adding a topper may not solve the underlying problem. Compared with the full mattress options, this is the choice for improving an existing sleep surface rather than replacing it.
Pros:
- Pre-shaped 21-inch right corner cut.
- Two foam layers, including memory foam and support foam.
- Removable cover with a zipper; product details say it is machine washable.
- Useful when you want to keep a properly fitting mattress and add cushioning.
Cons:
- It is a topper, not a full replacement mattress.
- Its 74-by-51-inch size and right-side cut may not fit smaller bunks or opposite-side cuts.
Verdict: Pick the Kistrba if your existing mattress fits the 74-by-51-inch profile and you want a shaped layer of added cushioning, not a new mattress.
4. Daspom 3.2-Inch Mattress with a 22-Inch Corner Cut
This Daspom option is listed at 74 by 51 inches and 3.2 inches thick, with a 22-inch corner cut. Its two-layer foam design uses memory foam over support foam, and the product is described as medium firmness. The removable cover can be machine washed, which is useful in a camper where bedding can pick up dust and travel grime.
The 22-inch cut sets it apart from the 21-inch shapes in this group. That one-inch difference may affect how well the mattress sits against the bunk wall or cabinetry, so do not assume the two sizes are interchangeable. The product information also lists a maximum weight capacity of 500 pounds; check the listing and your RV’s bunk limits when considering load.
At 3.2 inches, this is a relatively slim choice compared with the 4- and 4.7-inch mattresses. That may work when bunk clearance is limited or when you want a shaped replacement that is not too thick, but it offers less overall depth than the thicker foam choices.
Pros:
- 74-by-51-inch size with a stated 22-inch corner cut.
- Two-layer foam construction with memory foam and support foam.
- Removable, machine-washable cover.
- Medium firmness description and a listed 500-pound maximum capacity.
Cons:
- The 22-inch cut may not match bunks designed for a 21-inch angle.
- At 3.2 inches thick, it is thinner than several alternatives here.
Verdict: Choose this Daspom if your bunk needs the 74-by-51-inch size and 22-inch cut, and you prefer a thinner mattress with a washable cover.
5. Daspom 4.7-Inch Mattress for a 73-by-50-Inch Bunk
This Daspom mattress measures 73 by 50 inches and is listed as 4.7 inches thick, with a 21-inch corner cut. Its two-layer memory foam construction is described as medium firm, with a memory foam top layer and a support foam base. The product details also describe a removable cover that can be machine washed.
Among the full mattress choices here, this one offers the most listed thickness while keeping the same general footprint and cut size as the Camping World 73-by-50-inch model. That extra depth may appeal if you want more cushioning, but it also makes bunk clearance worth checking. Measure from the mattress platform to any upper bunk, wall, or cabinet that could limit the available height.
The listing describes the corner as 21 inches but does not identify the cut as left or right in the supplied details. That missing orientation is a key point to confirm before ordering. The product information also contains inconsistent weight and thickness fields, so use the stated 73-by-50-by-4.7-inch size as a starting point and verify the current listing details.
Pros:
- Listed size of 73 by 50 inches with a 21-inch corner cut.
- At 4.7 inches thick, it is the thickest full mattress in this selection.
- Two-layer foam construction with a memory foam comfort layer.
- Removable cover described as machine washable.
Cons:
- The supplied details do not specify whether the cut is left or right.
- Its greater thickness may not suit bunks with limited clearance.
Verdict: This is a promising option if you want a thicker 73-by-50-inch mattress, but confirm the cut direction and available bunk clearance before buying.
How to Choose an RV Double Bunk Mattress with a Cut Corner
Measure the bunk, not just the old mattress
Measure the mattress platform’s full length and width, then note where the angled section begins and ends. An old mattress may have compressed or shifted, so its dimensions may not reflect the bunk’s true size. Compare your measurements with the listed mattress dimensions, and leave room for any frame lip or surrounding cabinetry.
Confirm the corner’s side and angle
Write down whether the cut is on the left or right when you face the bunk from a consistent position, such as standing at its foot. Then measure the cut itself, not just the overall mattress. The products here include 21- and 22-inch cuts, while one curved option does not specify its angle. A matching length and width cannot make up for a cut that faces the wrong way.
Choose between a mattress and a topper
A full mattress is the better starting point if you are replacing the bunk’s sleep surface. A topper adds cushioning to an existing mattress and relies on that mattress for its base support. The Kistrba product in this group is described as a topper, so check that distinction before ordering it as a replacement.
Think about thickness and available clearance
These options range from 3.2 to 4.7 inches thick. A thicker mattress can change how much space remains between the bunk and an upper bed, wall, or nearby cabinet. Check both the bunk’s available height and any safety rails or fitted bedding that need to remain usable once the mattress is in place.
Compare foam construction and firmness descriptions
Several choices use layered foam, but their listed thicknesses and construction details differ. The Camping World 4-inch mattress is described as medium and uses memory foam. The Daspom options list memory foam over support foam, and the Kistrba topper has memory foam with a support layer. Firmness is personal, so consider what you prefer and what the existing bunk surface feels like before choosing.
Check the cover and care instructions
Removable covers can make cleaning easier, especially after trips with children or pets. The Kistrba topper and Daspom options are described as having removable covers; their supplied details say the covers can be machine washed. Check the current product instructions for the correct care method before laundering any cover.
Plan for setup and expansion
Some of these mattresses ship compressed. The Camping World Cozyway listing recommends allowing a few hours after unboxing for the foam to expand. Make sure you have enough space to unpack the mattress and let it expand before placing it on the bunk. Follow the instructions included with the specific product you order.
Frequently Asked Questions
How do I know which way the cut corner should face?
Stand at the same end of the bunk each time you check, then note whether the angled corner is on your left or right. Compare that orientation with the product listing or image. Do not rely on the word “right” alone unless you know the viewing direction used to describe it.
Are these mattresses interchangeable if they are both around 74 by 50 inches?
Not necessarily. Their corner cuts can differ in angle, length, and direction, and even a small mismatch can leave a gap or create an overhang. Match the full outline of your bunk, not only its overall dimensions.
Is the Kistrba product a mattress or a topper?
The listing title uses the word “mattress,” but the supplied product details describe it as a 3.2-inch mattress topper. Treat it as a topper for an existing mattress unless the current listing clearly states otherwise.
Which option is the thickest?
The Daspom option listed at 73 by 50 inches is 4.7 inches thick, making it the thickest full mattress among these picks. Check your bunk’s available clearance before choosing a thicker mattress.
Can I use a regular rectangular mattress or topper instead?
A rectangular option may not fit cleanly in a bunk designed around a cut corner. It can extend into cabinetry or leave unused space at the angled end. A shaped mattress or topper is usually the more direct match, provided its dimensions and orientation are correct.
Do compressed mattresses need time before use?
Some of these products ship compressed. The Camping World Cozyway listing recommends letting its mattress expand for a few hours after unboxing. Follow the instructions for the specific product you purchase, since setup guidance can vary.
Final Recommendation
For a full replacement with a clearly stated size and corner direction, the Camping World Cozyway 73-by-50-inch mattress is the easiest option here to evaluate—if your bunk needs a 21-inch right cut. If added thickness is your priority, consider the 4.7-inch Daspom, but confirm the cut’s orientation and bunk clearance first. For any of these choices, careful measuring is the best way to avoid a poor fit.
