Finding the best RV mattress with a radius corner starts with getting the shape right: a mattress that is too square can overhang a bunk or block nearby space.

Before ordering, measure your bunk and compare its corner shape and cut dimensions with the mattress listing.

Camping World Cozyway 8-Inch Mattress: Best for a Thicker Foam Bunk
This Camping World Cozyway mattress measures 51 by 74 inches and is 8 inches thick. Its 22-inch right corner angle is designed for a bunk with a matching cutout. The added thickness may suit you if you want more foam between you and the bunk base than the thinner options provide.
The product description highlights breathable materials, support, pressure relief, and CertiPUR-US foam. Those details are useful when comparing foam construction, though they do not tell you the exact firmness or guarantee that the mattress will feel right for every sleeper.
Check the cutout’s side and measurements before buying. This model specifies a right corner angle, so it may not fit a bunk with the angle on the opposite side. The listing describes an angled corner, not a rounded radius, so confirm the shape with the product images and your bunk measurements.
Pros:
- 8-inch thickness, more than the other two choices
- CertiPUR-US foam
- 51 x 74-inch size is clearly specified
- Right-side corner angle is identified in the product title
Cons:
- Thicker profile may not suit a bunk with limited clearance
- The specified right-side angle may not match every bunk layout
Verdict: Choose this one if your bunk fits its dimensions and right-side cutout, and you want an 8-inch foam mattress; skip it if your bed requires a different corner shape or side.
Camping World Cozyway 4-Inch Mattress: Best for Reversible Comfort
This 51 x 74-inch Camping World mattress is 4 inches thick and uses memory foam. Its reversible design offers a soft surface on one side and a firm surface on the other, giving you a way to change the feel without replacing the mattress. It is the only option here that specifically describes two comfort surfaces.
The listing also describes a water-resistant and stain-resistant cover, a practical feature for camper use. The mattress ships compressed; the product information recommends allowing a few hours for it to expand after unpacking. Its 22-inch corner cut is intended for RV bunks, but you should still check the cut’s position and shape against your bed.
At 4 inches thick, this model sits between the 8-inch Cozyway and the thinner Daspom. It may be a reasonable middle-ground choice if you want a reversible surface and a more compact profile than the 8-inch mattress. The product details do not specify the exact foam density or how firm each side will feel to you.
Pros:
- Reversible design offers soft and firm sleeping surfaces
- Water-resistant and stain-resistant cover
- 51 x 74-inch dimensions and 22-inch corner cut are specified
- Compressed shipping can make delivery and setup easier
Cons:
- Only 4 inches thick, which may not suit sleepers seeking a thicker mattress
- Allow time for the foam to expand after unpacking
Verdict: Pick this model if you want a reversible soft-or-firm option with a protective cover and its corner cut matches your bunk.
Daspom 3.2-Inch Mattress: Best for a Medium-Firm, Washable-Cover Option
The Daspom mattress measures 74 by 51 inches and is 3.2 inches thick. Its foam construction combines a memory-foam top layer with support foam below, and the listing describes the overall feel as medium firm. A 22-inch corner angle is intended to fit an RV bunk with a matching shape.
A practical distinction is its removable cover, which the product description says can be machine-washed on a gentle cycle. That may help with routine cleaning in a camper. The listing identifies the foam layers as 30D, but does not provide a specific weight limit or a detailed fit guide for different corner shapes.
The supplied product information marks this mattress as unavailable. Check its current listing status before planning a purchase. If it becomes available, compare its 3.2-inch height with your bunk’s available clearance and verify the angle before ordering. Its corner is described as angled, not as a rounded radius.
Pros:
- Medium-firm feel is specified
- Memory-foam top and support-foam base
- Removable cover can be machine-washed on a gentle cycle
- 22-inch corner angle is specified
Cons:
- At 3.2 inches thick, it is the thinnest option here
- Supplied availability information marks it as unavailable
Verdict: Consider the Daspom if its medium-firm design and washable cover meet your needs, but confirm availability and exact bunk fit before choosing it.
How to Choose an RV Mattress With a Corner Cut
Measure the Bunk and Its Corner
Measure the bunk’s length and width, then record the corner cut’s position and size. A mattress can have the right overall dimensions and still fit poorly if its angled corner is on the wrong side or the cut is too large or small. Compare your measurements with the product listing rather than relying on a general RV mattress label.
Check Whether You Need an Angle or a Rounded Radius
“Radius corner” can mean a rounded curve, while “corner cut” or “corner angle” usually describes a diagonal edge. The three options in this guide are described with angled cuts; the supplied details do not confirm rounded corners. If your bunk has a curved corner, check the product photos or contact the seller to confirm the mattress shape before ordering.
Choose a Thickness That Fits Your Setup
The choices range from 3.2 to 8 inches thick. A thicker mattress may change how much room remains above the bunk, so consider overhead clearance, bedding, and any nearby surfaces. Also check how the mattress will sit on the bunk base. The product details do not establish that any one thickness is right for every RV.
Compare the Foam and Feel
The options differ in construction and stated comfort features. The 8-inch Cozyway is described as foam with CertiPUR-US foam; the 4-inch Cozyway uses memory foam and offers reversible soft and firm sides; the Daspom combines memory foam and support foam and is listed as medium firm. Firmness is personal, so use those descriptions as a starting point rather than a guarantee of how a mattress will feel.
Consider Cleaning and Care
Camper mattresses can benefit from covers that are easier to care for. The 4-inch Cozyway listing describes its cover as water- and stain-resistant. The Daspom listing says its cover is removable and washable on a gentle cycle. The supplied details do not give the same cover-care information for the 8-inch Cozyway, so check its listing if that matters to you.
Plan for Delivery and Setup
The 4-inch Cozyway ships compressed, and its product information says to give the foam a few hours to expand after unpacking. If you are choosing another model, check its delivery and setup instructions on the product page. Allow space to position the mattress and verify its fit before adding bedding.
FAQs
Are these mattresses made with rounded radius corners?
The supplied product details describe corner angles or corner cuts, not rounded radius corners. If your bunk has a curved edge, confirm the mattress shape with the seller before ordering.
How do I measure an RV bunk corner cut?
Measure the bunk’s full length and width, then note which corner is cut and the cut’s dimensions. Compare those measurements and the cut’s side with the mattress listing. A matching overall size alone may not be enough for a close fit.
Which mattress is the thickest?
The Camping World Cozyway corner-cut mattress is 8 inches thick. The reversible Cozyway is 4 inches thick, and the Daspom is 3.2 inches thick.
Which option has a reversible feel?
The 4-inch Camping World Cozyway mattress is described as reversible, with a soft surface on one side and a firm surface on the other.
Which option has a washable cover?
The Daspom product description says its cover is removable and can be machine-washed on a gentle cycle. The 4-inch Cozyway is described as having a water- and stain-resistant cover, but the supplied details do not say that it is machine-washable.
Will a 51 x 74-inch mattress fit my RV bunk?
Not necessarily. Check the bunk’s actual length and width as well as the corner’s side, shape, and measurements. The 51 x 74-inch size is listed for both Camping World mattresses, but the corner details differ.
Which mattress should I choose?
For a thicker foam option, consider the 8-inch Cozyway if its right-side angle matches your bunk and you have enough clearance. For reversible comfort and a water- and stain-resistant cover, consider the 4-inch Cozyway. The Daspom may suit you if you want a medium-firm design and washable cover, but its supplied availability status is unavailable.
Final Recommendation
The 4-inch Camping World Cozyway is the most flexible pick if you want a reversible soft-or-firm surface and a water- and stain-resistant cover. Choose the 8-inch Cozyway if thickness is your priority and the specified right-side corner angle fits. The Daspom offers a washable cover and medium-firm feel, but check whether it is available. Most important, confirm whether your bunk needs an angled cut or a rounded radius before ordering, since the listed product details describe angled corners rather than confirmed rounded ones.
