A king topper that is the wrong length or width can overhang the frame or leave a gap at the sides and foot.
This roundup covers seven king mattress toppers and pads, from 3 in dual-layer foam to 4 in gel foam and soft pillow-top pads. We compare size, thickness, type and base compatibility for each.
The seven fall into three groups: two 3 in dual-layer toppers, two 4 in gel foam toppers from the same line, and three pillow-top and quilted pads with no published thickness.

The 7 best RV king mattress toppers in detail
The two CozyRelief models share a name, so read the size line on each card before you choose. The 72 x 80 in model is for a standard RV king, and the 72 x 75 in model is for a short king.
The ELEMUSE scores highest because it pairs a clear size, a known 3 in thickness and a washable cover. The MATBEBY scores lowest because it's a plain polyester pad with no foam layer and no published thickness.
ELEMUSE RV King 3 in Foam and Pillow Top
- 72 x 80 in
- 2 in cooling gel foam
- 1 in quilted pillow top
- Removable machine-washable cover
Two layers in one 3 in topper give a firm RV king a plush top, and the pillow top can be used alone. The foam itself should never be washed.
Pros
- Pillow top works alone or with the foam
- Removable pillow-top cover that machine washes
- Elastic skirt for 8 to 21 in mattresses
Cons
- Foam should not be washed
- Fabric is made in China
- Allow 12 to 48 hours for full expansion
Two layers in one 3 in topper suit a firm RV king that needs a plush layer. A 2 in gel-infused memory foam pad pairs with a 1 in quilted pillow top of down alternative fiber, and you can use both layers or either one alone.
ELEMUSE calls the top layer plush, which suits a sleeper who wants to try a softer surface before buying a thicker topper. The pillow-top cover comes off for the washer, and an all-around elastic skirt wraps mattresses 8 to 21 in deep.
Skip it if you want the foam washed or if origin matters to you: the memory foam can't go in the machine, and the fabric is made in China. Allow 12 to 48 hours for full expansion after you unfold both layers.
Camping World CozyRelief 4 in King Topper
- 72 x 80 in
- 4 in, three layers
- Cooling gel-infused foam
- Works with a slatted base
A 4 in gel foam layer in 72 x 80 in suits a standard RV king on a slatted base. It adds 4 in of height, so check clearance first.
Pros
- Medium plush feel
- Works with a slatted base
- Gel-infused foam that Camping World says reduces heat buildup
Cons
- Adds 4 in of height, so check clearance
- No weight published for this size
The CozyRelief 72 x 80 in is built for a standard RV king on a slatted base. It's a three-layer, 4 in gel foam topper, and Camping World describes the feel as medium plush.
It suits a sleeper who wants a thick, cushioned top across the full width of the bed. Camping World says the gel-infused foam helps regulate temperature, and the slatted-base fit matters if your RV uses slats rather than a solid platform.
Skip it if your cabinets sit low, since at 4 in it adds more height than the 3 in options here.
Camping World CozyRelief 4 in Short King Topper
- 72 x 75 in
- 4 in, three layers
- 29.6 lb
- Works with an adjustable base
The 72 x 75 in short king size suits a bed that is 5 in shorter than a standard RV king. At 29.6 lb, it needs a lift bed that can carry the weight.
Pros
- Short king size for shorter beds
- Works with an adjustable base
- Medium plush 4 in layer
Cons
- 29.6 lb, so check that a lift bed can carry it
- Adds 4 in of height, so check clearance
The CozyRelief short king fits a 72 x 75 in bed, which is 5 in shorter than a standard RV king. Camping World designs it for larger motorhomes and fifth wheels, with medium plush comfort from a 4 in gel foam layer.
It suits a couple on a larger rig, and it works with adjustable bases. At 29.6 lb it is heavy, so check that a lift bed can carry the weight before you buy.
Skip it if your bed is 72 x 80 in, since a short king topper will leave a gap at the foot. It also adds 4 in of height, so check clearance.
ABENE RV King 3 in Dual Layer Topper
- 72 x 80 in
- 2 in cooling gel foam
- 1 in soft pad
- Machine washable pad
A brushed microfiber top over 2 in of gel foam suits a sleeper who wants a soft, breathable surface. ABENE doesn't publish a pocket depth, so measure before you order.
Pros
- Two layers in one 3 in topper
- Brushed microfiber that ABENE calls breathable
- Fitted design with strong elastic edges
Cons
- No pocket depth published
- Not water resistant
Pick the ABENE for a 72 x 80 in RV king when you want a 3 in dual-layer topper with a brushed microfiber top. A 2 in gel-infused memory foam layer sits under a 1 in soft mattress pad.
It suits a sleeper who wants a soft, breathable surface without a thick stack. ABENE says the gel foam helps dissipate heat and the microfiber promotes airflow, and strong elastic edges are meant to reduce shifting and bunching.
Skip it if you need a pocket depth in inches: ABENE doesn't publish one, so measure your mattress and check with ABENE before you order. The pad is machine washable, but it isn't water resistant.
SakuraHome RV King 1000 GSM Pillow Top
- 72 x 80 in
- 1000 GSM down alternative fill
- Bamboo viscose blend cover
- Pocket 8 to 21 in
A soft 1000 GSM pillow top adds loft to a firm RV king without a foam layer, and the cover washes in the machine. SakuraHome doesn't publish a thickness, so check clearance first.
Pros
- 1000 GSM down alternative fill
- Bamboo viscose cover that is OEKO-TEX certified
- Machine washable in cold, tumble dry low
Cons
- No thickness published
- Pocket depth is given two ways, 18 in and 8 to 21 in
For a firm RV king that needs a soft pillow top and nothing more, the SakuraHome fits. It has 1000 GSM of down alternative fill, which SakuraHome says is nearly double the fill of standard 600 GSM pads, and its bamboo viscose blend cover is OEKO-TEX certified.
It suits a sleeper who likes a soft, cloud-like top and wants a washable pad. The RV king size is 72 x 80 in, and the cold machine wash plus low tumble dry keeps care simple.
Skip it if you want firm support or a known thickness. SakuraHome describes the top as soft and doesn't publish a thickness, so check clearance before you buy.
The pocket depth is given two ways, 18 in and 8 to 21 in, so confirm the number with SakuraHome before you order.
EASELAND RV King Cotton Pillow Top Pad
- 72 x 80 in
- 21 in deep pocket
- 100% cotton face
- 59 oz down alternative fill
A cotton top over a 21 in pocket gives a soft, washable pad for a 72 x 80 in RV king. EASELAND doesn't publish a thickness, so check clearance before you order.
Pros
- 100% cotton face at 300 thread count
- 21 in deep pocket
- Machine washable
Cons
- No thickness published
- Needs tumble drying or sun-drying to fluff after shipping
A soft cotton top and a deep pocket are what the EASELAND brings to a king bed. It has a 100% cotton face at 300 thread count, a 21 in deep pocket and 59 oz of down alternative microfiber fill.
It suits a sleeper who wants a washable pad that feels like bedding. EASELAND says the cotton surface absorbs sweat, and the pad is boxing quilted with a single-track elastic pocket that stretches 8 to 21 in.
Skip it if you need the pad to fluff immediately, since it ships compressed and needs 20 minutes of low tumble drying or 4 to 6 hours in the sun. EASELAND doesn't publish a thickness, so check clearance before you order.
MATBEBY RV King Quilted Pad
- 72 x 80 in
- 8 to 21 in pocket
- Quilted polyester
- 5.7 lb
A quilted pad with an 8 to 21 in pocket is a light, plain option for a 72 x 80 in RV king. MATBEBY doesn't publish a thickness, so check clearance before you choose it.
Pros
- Pocket fits 8 to 21 in mattresses
- Light at 5.7 lb
- 1-year quality assurance from MATBEBY
Cons
- No thickness published
- A polyester pad with no foam layer
Plain and light, the MATBEBY is a quilted pad for a 72 x 80 in RV king. It's 100% polyester with a polyester microfiber filling, and the pocket fits mattresses 8 to 21 in deep.
It suits a sleeper who wants a pad that's easy to pull off and wash. At 5.7 lb it is manageable on a bed, and MATBEBY backs it with a 1-year quality assurance.
MATBEBY describes the cover as breathable and cooling, and says the pad dries quickly.
Skip it if you want a thick cushion or a foam layer, since this is a pad with no foam. Care is a cold gentle wash and low tumble dry, with no ironing or dry cleaning.
Side by side: size, thickness and type
Four of these toppers are 3 or 4 in thick, and three don't publish a thickness. The size column matters more than the thickness for a king bed, because a width or length mismatch shows up on the first night.
Where the table has no thickness, the brand doesn't publish one.
| Product | Best for | Size | Thickness | Type | Our score |
|---|---|---|---|---|---|
| ELEMUSE RV King 3 in Foam and Pillow Top | a foam and pillow-top mix | 72 x 80 in | 3 in | Gel foam with pillow top | 8.9 |
| Camping World CozyRelief 4 in King Topper | a slatted-base RV king | 72 x 80 in | 4 in | Gel memory foam, medium plush | 8.8 |
| Camping World CozyRelief 4 in Short King Topper | short king beds | 72 x 75 in | 4 in | Gel memory foam, medium plush | 8.6 |
| ABENE RV King 3 in Dual Layer Topper | a brushed microfiber top | 72 x 80 in | 3 in | Gel foam with microfiber pad | 8.4 |
| SakuraHome RV King 1000 GSM Pillow Top | a soft bamboo pillow top | 72 x 80 in | Not listed | Pillow top pad, bamboo viscose | 8.2 |
| EASELAND RV King Cotton Pillow Top Pad | a cotton top | 72 x 80 in | Not listed | Cotton top, down alternative fill | 8.0 |
| MATBEBY RV King Quilted Pad | a plain quilted pad | 72 x 80 in | Not listed | Quilted polyester pad | 7.8 |
A 72 x 80 in topper and a 72 x 75 in topper look alike in a table, but they suit different frames. The 5 in difference in length matters: the CozyRelief 72 x 80 in works with a slatted base, while the 72 x 75 in works with an adjustable base.
How we picked these seven
We compared specs, materials, sizes and base compatibility, then scored each pick against what an RV king bed needs. Our score weighs specs, features and buyer feedback against what you're shopping for.
Length and width come first for a king bed, since a topper with the right thickness but the wrong width is no use. Thickness, pocket depth and base type come next, because they decide clearance and fit.
RV king sizes: 72 x 80, 70 x 80 and short king
Three king sizes come up in RVs, and none of them matches a home king. Here is how they compare:
| Size | Where you see it | What to buy |
|---|---|---|
| 72 x 80 in | Standard RV king, the size used by six of the seven toppers here | 72 x 80 in topper or pad |
| 70 x 80 in | Some motorhomes | A 70 x 80 in topper, or a 72 in topper with a deep skirt |
| 72 x 75 in | Short king, made for larger motorhomes and fifth wheels | 72 x 75 in topper |
| 76 x 80 in | Home king | Not an RV king size |
Measure your bed at its widest and longest points, then match the topper's inches to those numbers. The 70 x 80 in bed is the one that catches people out, because a 72 in topper is 2 in wider than the frame.
None of the seven toppers here comes in a 70 x 80 in size. A 70 in bed means using a 72 in topper and accepting the overhang, which a skirt can manage.
For the full size chart, see RV mattress sizes. If your bed is a short queen rather than a king, use the short queen topper roundup instead.
A queen-size RV bed has its own picks too, in our RV queen mattress topper roundup.
Overhang and skirts when a topper is wider than the bed
A 72 in topper on a 70 in bed hangs 1 in past each side, and a deep-pocket skirt holds that extra width neatly against the sides. A topper narrower than the bed leaves a strip of bare mattress at each side.
A flat topper with no skirt will drift on a 70 in bed more easily than a pad with a pocket, because nothing holds its sides. Five of the seven toppers here have elastic skirts or edges, so they are the easier choice when your width is uncertain.
That is why the 72 in width is the safer choice if you are not sure whether your bed is 70 or 72 in. Measure the width at the head and foot, and write down both numbers before you shop.
If the two numbers differ, compare the smaller one with the topper's width, since the smaller number is the one that decides whether there is a gap.
Skirt depth and shifting on an RV king mattress topper
Skirt depth matters, since a short skirt will not hold a thick mattress. ELEMUSE, EASELAND and MATBEBY fit mattresses 8 to 21 in deep, SakuraHome gives both 18 in and 8 to 21 in, and ABENE doesn't publish a depth.
Our guide to keeping an RV mattress from sliding covers straps and gripper pads for toppers that still shift.
Slatted or adjustable base: check your frame
Base type matters because a foam topper rides on the frame, and the two CozyRelief models suit different bases. The 72 x 80 in works with a slatted base, and the short king works with an adjustable base.
Check your frame or ask the RV maker which base you have before you buy. If your bed is on slats, the 72 x 80 in CozyRelief is the one made for a slatted base.
The other five brands don't name a base, so check with the brand if base type matters for your bed.
Lift beds are a separate question, so check the lift's rated capacity before you add weight to it, especially with the 29.6 lb short king.
Thickness, weight and clearance for a king bed
The two CozyRelief toppers are the thickest here at 4 in, while the ELEMUSE and ABENE add 3 in. That 1 in difference can matter when clearance is tight.
SakuraHome, EASELAND and MATBEBY don't publish a thickness, so check with the brand before you buy if clearance is tight.
Add the topper's thickness to your current mattress height, then compare the total with the clearance under cabinets, windows and the ceiling.
The short king CozyRelief weighs 29.6 lb, so check the lift struts if your bed lifts. Camping World doesn't publish a weight for the 72 x 80 in CozyRelief, so ask Camping World before you buy.
Compressed toppers need time to expand. ELEMUSE says to allow 12 to 48 hours, so measure the height after the topper opens rather than out of the box.
Measure the height at the slide-out edge as well as the middle of the bed, since the slide frame can be the closest point to the topper.
When a topper will not fix a worn king mattress
A topper can soften a firm king bed, but it cannot rebuild a sagging or broken mattress. If the mattress has a deep dip or foam that no longer springs back, a new mattress is usually the better fix.
If the mattress is in good shape but feels too firm, a topper is the more direct fix.
Press along the middle and the edges of the mattress with a flat hand, and note whether the surface springs back.
Note whether the problem is the surface, which a topper can change, or the support underneath, which it cannot. Read the topper or new mattress guide before you spend on a topper.
If you have ongoing back, hip or shoulder pain, talk with a doctor, since a topper is only one part of how you sleep.
Shipping, expansion and the first night
Two of the toppers here arrive compressed, and the wait before you use them varies. ELEMUSE says 12 to 48 hours, and EASELAND says to tumble dry on low heat for 20 minutes or sun-dry for 4 to 6 hours.
Open the topper a few days before you need it, and lay it flat somewhere warm and dry while it expands. Do not judge the feel until it has its full loft, since a topper that is still flattened will feel firmer than it really is.
If you wash a pad often, check the care label first. The EASELAND, ABENE, SakuraHome and MATBEBY pads are machine washable, while the ELEMUSE foam should never be washed, so only its pillow-top cover goes in the machine.
The ELEMUSE, ABENE, SakuraHome, EASELAND and MATBEBY aren't water resistant, so wipe spills right away.
Which king topper fits your RV bed
Pick the ELEMUSE if you want two layers and a removable pillow top, and the CozyRelief 72 x 80 in if you want a thick gel foam layer on a slatted base. Pick the CozyRelief short king only if your bed is 72 x 75 in and its frame can carry 29.6 lb.
If two toppers fit your bed, let the clearance decide. A 3 in topper leaves more room under a low cabinet or a closed slide-out than a 4 in one, and you notice that gap every time you make the bed.
Pick the ABENE if you like a brushed microfiber top over a 2 in gel foam layer. Pick the SakuraHome or the EASELAND if you want a soft, washable pillow top, and ask about the thickness first.
Pick the MATBEBY if you want a plain quilted pad with a light weight. If clearance and feel point in different directions, measure the height first, then choose the feel that fits under it.
If you run warm, favor the cotton top or the gel foam with cooling gel, and if you wash often, favor the machine washable pads.
For the sizes behind these numbers, read RV king mattress size. To check your bed's inches, see how to measure an RV mattress.

Frequently asked questions
What size is an RV king mattress topper?
Most RV king toppers in this roundup are 72 x 80 in, and a short king is 72 x 75 in. Some motorhomes use a 70 x 80 in bed, so measure the width and length at the head and foot before you order.
Will a 72 x 80 topper fit a 70 x 80 RV bed?
It will fit, but a 72 in topper hangs 1 in past each side of a 70 in bed. A deep-pocket skirt holds that extra width neatly, while a topper narrower than the bed leaves a bare strip at each side.
Can you use a home king topper on an RV king bed?
Usually not, because a home king is typically 76 x 80 in, which is wider than an RV king and may hang past the sides. Choose a topper sized for your RV bed, and check the width at the head and foot before you order.
How do you know if an RV bed uses a slatted or adjustable base?
Check the bed frame or ask the RV maker, since the base type is part of how the bed is built and changes which topper you need. The two CozyRelief king models suit different bases, so match the model to the base you have.
