Finding the best RV short king mattress topper in 72 x 75 inches starts with one simple check: confirm the topper’s actual size, not just whether the listing says “RV King.” RV beds come in different dimensions, and a topper that is too long or wide can bunch up or leave parts of your mattress uncovered. Of these five options, the Camping World CozyRelief is the clearest match for a 72 x 75-inch bed. The other picks include alternatives for extra-plush comfort, mattress protection, or different bed sizes, so check their fit notes before buying.

Camping World CozyRelief: Best Exact-Size Memory Foam Match
The CozyRelief is the most direct fit for shoppers searching for a 72 x 75-inch short king topper. Its four-inch gel memory foam layer is designed to add cushioning over a firm or aging RV mattress, without replacing the mattress itself. The plush feel and body-conforming foam may appeal if you want more padding around pressure points such as your hips and shoulders.
Gel is included to help reduce heat buildup, though it should not be treated as a guarantee that you will sleep cool. Memory foam can feel more enveloping than a fiber-filled pillow top, which some sleepers enjoy and others may find too soft or warm. The product information also describes the feel as medium plush, so expect a comfort layer rather than a firm support surface.
Some owners describe a noticeable improvement in comfort on hard RV beds, particularly when extra cushioning is needed around the hips. Its stated 72 x 75-inch dimensions make it easier to assess for a short king than the other comfort toppers here. Still, measure your mattress and available space first, especially if the bed sits in a close-fitting slide-out.
Pros:
- Listed in the exact 72 x 75-inch short king size
- Four inches of gel memory foam for added cushioning
- Plush feel designed to relieve pressure
- Made specifically for RV beds such as those in motorhomes and fifth wheels
Cons:
- Memory foam may feel too soft or enveloping for some sleepers
- Gel is intended to help with heat, but cooling results can vary
Verdict: Choose the CozyRelief if you want a substantial foam comfort layer and need a topper listed at 72 x 75 inches.
SakuraHome RV King Pillow Top: Best for a Soft, Washable Layer
This SakuraHome topper is a fiber-filled pillow top rather than a thick block of memory foam. Its 1000 GSM filling is intended to create a soft, lofty surface, while the fabric combines polyester with bamboo-derived viscose. The listing also describes the material as breathable and OEKO-TEX certified.
The deep-pocket skirt is designed for mattresses from 8 to 21 inches thick, and the topper is machine washable according to the product details. Those features can be useful in an RV, where bedding may need regular cleaning and a secure fit. Some owners describe it as fluffy and comfortable, with a soft feel that stays in place on their beds.
The key limitation for this search is sizing: the listing identifies it as RV King but does not provide the exact 72 x 75-inch dimensions in the supplied product details. RV king sizes are not always interchangeable, so verify the measured length and width before ordering. Its pillow-top fill also adds surface softness, not the same body-contouring support as the CozyRelief’s four-inch foam.
Pros:
- Plush pillow-top design with 1000 GSM filling
- Bamboo-derived viscose and polyester fabric
- Machine washable according to the care instructions
- Deep-pocket skirt fits mattresses listed as 8 to 21 inches thick
Cons:
- Exact 72 x 75-inch dimensions are not confirmed in the supplied details
- Provides a soft surface layer rather than a thick memory foam upgrade
Verdict: Consider SakuraHome if you prefer a washable, fluffy pillow top, but confirm the topper’s exact dimensions with the seller before using it on a 72 x 75-inch mattress.
ELEMUSE Pillow Top: A Plush Option for a 72 x 80-Inch RV Bed
The ELEMUSE is a plush topper with brushed microfiber fabric and down-alternative filling. Box stitching is intended to help distribute the fill, and its deep pocket is listed for mattresses 8 to 21 inches thick. The manufacturer describes the fill as breathable and cooler than memory foam, making this a different option for shoppers who prefer a cushioned fiber layer over foam.
There is an important size mismatch to note: although the product title calls it a short king topper, the supplied size list gives the RV King dimensions as 72 x 80 inches. That is five inches longer than a 72 x 75-inch short king mattress. Based on the listed dimensions, this is not the right fit for the target bed unless your mattress measures 72 x 80 inches.
The topper is described as machine washable, with cold water, a gentle cycle, and low-heat drying recommended. Some owners report that it makes a firm surface more comfortable, while others may want more substantial support than a fiber-filled pad can provide. Treat the size details as the deciding factor before considering its comfort features.
Pros:
- Plush down-alternative fill with a soft microfiber cover
- Box stitching helps keep the filling distributed
- Deep-pocket design listed for 8- to 21-inch mattresses
- Care instructions allow machine washing
Cons:
- Listed RV King size is 72 x 80 inches, not 72 x 75 inches
- Fiber fill may not provide the same contouring as memory foam
Verdict: The ELEMUSE is worth considering for a measured 72 x 80-inch RV bed, but its listed size makes it a poor match for a true 72 x 75-inch short king.
Coldwind Waterproof Pad: Best for Protecting a Short King Mattress
The Coldwind is a mattress protector, not a thick comfort topper. It is listed at 72 x 75 inches and includes a 14-inch deep pocket, an elastic edge, a quilted microfiber top, and a waterproof TPU layer. The surface is described as absorbent, while the waterproof layer is intended to help shield the mattress from spills and moisture.
This can be a useful choice if your RV mattress already feels comfortable and your main concern is keeping it protected. The quilted pad may add a little softness, but it is not designed to transform a firm mattress like a four-inch memory foam topper. Some owners describe the material as soft and appreciate the fit, though the quilting may be thinner than shoppers expecting a cushioned topper might assume.
Pros:
- Listed dimensions match a 72 x 75-inch short king mattress
- Waterproof TPU layer helps protect against spills
- 14-inch pocket and elastic edge help secure the pad
- Machine washable according to the product details
Cons:
- It is a protector, not a thick comfort topper
- Quilting may feel too thin if you want a major softness upgrade
Verdict: Pick the Coldwind if mattress protection is your priority; for noticeable added cushioning, pair your search with a true foam or pillow-top topper instead.
JSELF Cooling Gel Topper: A Standard King Near-Match, Not a Short King Fit
The JSELF is a three-inch gel memory foam topper made for a standard king mattress measuring 76 x 80 inches. Its product details describe a dual-layer construction, a breathable fabric cover, an anti-slip base, and adjustable corner straps. The cover is listed as removable and machine washable, and the foam is identified as CertiPUR-US certified.
Those details may make it appealing for a standard king bed, but its listed footprint is four inches wider and five inches longer than a 72 x 75-inch short king. That is a substantial difference for an RV mattress, where the bed may fit tightly into a platform or slide-out. Do not assume the straps will make an oversized topper fit correctly.
For a true short king, this is not a dependable fit based on the dimensions provided. If you are shopping for a standard king instead, the foam construction and straps offer a different setup from the CozyRelief, but note that the supplied details do not list this as an RV short king size.
Pros:
- Three-inch gel memory foam construction
- Includes an anti-slip base and adjustable corner straps
- Removable, machine-washable cover
- Foam is listed as CertiPUR-US certified
Cons:
- Standard king dimensions of 76 x 80 inches do not match a 72 x 75-inch bed
- Not identified in the supplied details as an RV short king topper
Verdict: Choose the JSELF only if your mattress is a standard 76 x 80-inch king; its listed size makes it unsuitable for a 72 x 75-inch RV short king.
How to Choose an RV Short King Mattress Topper
Measure Your Mattress, Not Just the RV Bed Label
Measure the mattress from edge to edge across both the width and length. A “short king” is commonly used to describe a 72 x 75-inch RV mattress, but product listings may use “RV King” for a different size. In this group, the CozyRelief is listed at 72 x 75 inches, while the ELEMUSE RV King listing gives dimensions of 72 x 80 inches. Check the size chart and, if it is unclear, confirm the measurements with the seller.
Decide Whether You Need Comfort or Protection
A foam or pillow-top topper is meant to change how the bed feels. A mattress protector is mainly intended to help guard the mattress from spills and moisture. The Coldwind is a waterproof protector with light quilting, not a thick comfort layer. If your mattress is uncomfortable, look for a topper with enough cushioning for your needs; if the mattress feels fine and you want a protective barrier, a pad may be enough.
Choose a Fill That Matches Your Comfort Preference
Memory foam contours more closely to the body and can provide a cushioned feel around pressure points. Fiber-filled pillow tops tend to feel loftier and less conforming. Neither style is best for everyone. Consider whether you like a body-hugging surface or a more traditional soft, quilted layer, and remember that cooling claims are not a guarantee of a particular sleeping temperature.
Check Topper Thickness and Available Space
A thicker topper can change the height of your bed and may affect how sheets fit or how the mattress sits within an RV platform. Measure the available clearance around the mattress, especially if it is tucked into a slide-out or enclosed frame. Also check the mattress depth and the topper’s pocket or securing design so the bedding can sit properly.
Look at Care Instructions and Attachment Features
RV bedding can be exposed to more spills, dust, and frequent use than a rarely moved guest bed. Check whether the topper is machine washable or whether only its cover can be washed. For fiber-filled toppers, follow the stated wash and dry instructions to help maintain the fill. If your mattress moves or adjusts, pay attention to elastic skirts, straps, or other features intended to help keep the topper in place.
Frequently Asked Questions
What size is an RV short king mattress?
A 72 x 75-inch mattress is often called an RV short king, but always measure your own bed. Some listings use “RV King” for a 72 x 80-inch mattress or do not provide exact dimensions, so the label alone is not enough to confirm fit.
Which product here is listed at 72 x 75 inches?
The Camping World CozyRelief memory foam topper and the Coldwind waterproof mattress pad are both listed at 72 x 75 inches. The CozyRelief is designed to add cushioning, while the Coldwind is primarily a mattress protector.
Is the ELEMUSE topper a fit for a 72 x 75-inch bed?
The supplied size details list its RV King option as 72 x 80 inches. That is longer than a 72 x 75-inch mattress, so do not assume it will fit a short king based on the product title alone.
Will a standard king topper fit an RV short king?
Not reliably. The JSELF topper is listed at 76 x 80 inches, which is wider and longer than a 72 x 75-inch bed. A topper that is too large can overhang or bunch, especially in an RV bed frame.
Does a waterproof mattress pad add much softness?
A quilted protector may add a small amount of padding, but it is not the same as a thick foam or pillow-top topper. Choose a protector for mattress protection and a dedicated comfort topper if you want a larger change in feel.
Is gel memory foam guaranteed to sleep cool?
No. Gel is intended to help reduce heat buildup, but how cool a topper feels can vary by sleeper, room temperature, bedding, and mattress setup. Consider the full construction and your own comfort preferences rather than relying on the word “cooling” alone.
Final Recommendation
For a mattress that measures exactly 72 x 75 inches, the Camping World CozyRelief is the clearest pick for adding substantial cushioning because its listed size matches the bed and it uses a four-inch gel memory foam layer. Choose the Coldwind instead if you mainly want a waterproof cover and your current mattress already feels comfortable. The SakuraHome may suit shoppers who want a fluffy, washable pillow top, but confirm its dimensions first. The ELEMUSE and JSELF are listed in sizes that do not match a 72 x 75-inch short king, so verify your mattress measurements before considering either one.
