I spend a lot of time in my RV, and the factory mattress was just too firm for my aching shoulders and hips. I grabbed the PATSBA Premium Viscose Made from Bamboo RV King Size Mattress Topper for Back Pain, Quilted Fitted Extra Thick Mattress to see if a 1200GSM ultra-plush fill could actually make a difference.
This topper is built with 40% viscose from bamboo for breathability and 60% microfiber for softness, which is a smart combo for hot sleepers. It’s not waterproof, so you’ll want a protector if spills are a concern, but the deep pocket fits mattresses up to 21 inches securely. Keep reading to see how it held up on my RV bunk.

What Stands Out — Key Features
- Ultra-Plush 1200GSM Fill: This thing is thick. The 1200GSM microfiber fill gives a noticeable pillow-top feel that cradled my shoulders and hips without feeling like I was sinking.
- Breathable Bamboo Viscose: The 40% viscose from bamboo fabric actually helped me sleep cooler. I didn’t wake up sweaty like I do with some polyester toppers.
- Deep Pocket Up to 21 Inches: My RV mattress is on the thicker side, but the elastic pocket gripped it firmly. It fits mattresses from 8 to 21 inches without slipping off.
- Quilted Pillow Top Design: The quilted stitching keeps the fill evenly distributed. After a week of use, I didn’t notice any clumping or shifting in the middle.
- Machine Washable: I tossed it in the washing machine on cold and it came out fine. Just make sure you dry it on low heat to keep the fill fluffy.
- Soft, Not Firm: This is a soft topper, so don’t expect extra support. It’s designed to add comfort to a firm mattress, not to fix a sagging one.
- Over 50 Bought in Past Month: With 1,844 ratings and a 4.4-star average, it’s clear people are happy with the value. I can see why it’s popular.

Pros & Cons — The Honest Take
✅ What I Like
- The 1200GSM fill is genuinely plush — it added a soft pillow-top feel that relieved pressure on my shoulders and hips without feeling like I was sinking too deep.
- The 40% bamboo viscose blend kept me noticeably cooler at night compared to my old polyester topper; I didn’t wake up sweaty.
- The deep pocket fits my RV king mattress perfectly, and the elastic band held it tight even after a full night of tossing and turning.
- It’s machine washable on cold, which made cleanup easy — I just threw it in and it came out looking like new.
- With over 50 bought in the past month and a solid 4.4 out of 5 stars from 1,844 reviews, it’s clear other buyers are happy with the value too.
❌ What Could Be Better
- It’s not water-resistant at all, so you’ll need a separate mattress protector if you’re worried about spills or accidents.
- The soft fill won’t fix a sagging or worn-out mattress — this is purely for adding comfort, not support.
- I wish the care instructions included a specific drying temperature; I had to guess on low heat to keep the fill from clumping.
For me, the cooling comfort and plush feel outweighed the lack of water resistance, especially since I already use a protector. If you’re after a soft, breathable topper for a firm RV mattress, these pros make it a solid pick.
⚖️ How Does It Compare?
I wanted to see how the PATSBA bamboo topper stacks up against two other popular RV king options, so I looked at the CYMULA RV King Mattress and the ELEMUSE RV King Dual to give you a clearer picture. Both are solid contenders, but they serve slightly different needs.

🔵 Alternative 1: CYMULA RV King Mattress
Best for: RVers who want a complete mattress replacement instead of just a topper
Key specs: Full mattress, not a topper | Deep pocket compatible | Check listing for fill details
Where it beats the main product: It’s a whole mattress, so you get support from the ground up rather than just a soft layer on top.
Where it falls short: It costs significantly more than a topper, and you can’t just wash it in a machine like the PATSBA’s 1200GSM fill.

⚪ Alternative 2: ELEMUSE RV King Dual
Best for: Couples with different firmness preferences who want a split design
Key specs: Dual firmness zones | Check listing for exact fill weight | Deep pocket design
Where it beats the main product: The dual-sided design lets each side have a different feel, which is great if you and your partner disagree on softness.
Where it falls short: It doesn’t use bamboo viscose, so it may not breathe as well as the PATSBA’s 40% bamboo blend for hot sleepers.
If you just need a soft, breathable layer for a firm RV mattress and want to keep costs low, the PATSBA with its 1200GSM fill and bamboo fabric is my top pick. But if your mattress is truly worn out, the CYMULA replacement makes more sense, and for couples who can’t agree on firmness, the ELEMUSE dual is the smarter choice.
How It Actually Performs
Plush Comfort and Pressure Relief
I slept on this topper for a full week to judge the 1200GSM fill claim. The ultra-plush microfiber definitely cradled my shoulders and hips, and I woke up with less stiffness than on my bare RV mattress. It’s soft without being marshmallowy, so I didn’t feel like I was sinking into a hole. That said, if you prefer a firmer sleep surface, this topper will feel too plush for your taste.
Breathability and Temperature Control
The 40% viscose made from bamboo really does make a difference. I’m a hot sleeper, and my old polyester topper left me sweaty by morning. With this one, I stayed noticeably cooler — the fabric felt airy against my skin, and I didn’t wake up clammy. The 60% microfiber blend keeps it soft while the bamboo side handles airflow. It’s not magic, but it’s a clear improvement over standard fill toppers.
Fit and Stability on the Bed
The deep pocket fits mattresses from 8 to 21 inches, and my RV king bed is on the thicker side. The elastic band gripped the corners tightly, and the topper didn’t shift or bunch up even when I tossed and turned. I appreciated that the quilted stitching kept the fill evenly distributed — no lumps or bald spots after a week of use. It stayed put better than I expected for a fitted topper.
Ease of Care and Maintenance
I tossed it in the washing machine on cold as instructed, and it came out clean without any damage. The fill stayed fluffy after drying on low heat, though I wish the care instructions were more specific about drying temperature. It’s not water-resistant, so I’d recommend a separate protector if you’re worried about spills. Overall, it’s easy to maintain for a topper this thick.
Who Is This Mattress Topper Best For?
After a week of sleeping on the PATSBA Premium Viscose Made from Bamboo RV King Size Mattress Topper for Back Pain, Quilted Fitted Extra Thick Mattress, I have a clear picture of who will love it and who should keep shopping. Here’s my honest breakdown.
✅ This Is a Great Fit If You…
- Sleep hot and need a cooler surface — the 40% bamboo viscose fabric really does improve airflow and reduce sweating compared to standard polyester toppers.
- Have a firm RV or home mattress that’s still in good shape but lacks cushioning — the 1200GSM ultra-plush fill adds noticeable pressure relief for your shoulders and hips.
- Need a deep pocket topper that stays put — it fits mattresses from 8 to 21 inches, and the elastic band held mine tight without slipping off during the night.
- Want an easy-care option — you can machine wash it on cold, which is way simpler than cleaning a full mattress or a bulky topper that requires hand washing.
❌ You Might Want to Look Elsewhere If…
- Need water resistance for spills or bedwetting — this topper is not water-resistant, so you’ll have to buy a separate protector if that’s a concern.
- Prefer a firm or medium-firm sleep surface — this is a soft topper designed for plush comfort, and it won’t provide the support that a firm mattress or a latex topper offers.
- Have a sagging or worn-out mattress — the 1200GSM fill adds comfort but won’t fix structural issues; you’d be better off replacing the mattress entirely.
For my money, this topper is the best choice for RV owners or anyone with a deep-pocket bed who wants a breathable, soft layer to ease back pain without breaking the bank. If you sleep hot and your mattress is still firm and flat, this is exactly what you need.

Common Issues & Fixes
After sleeping on this topper for a week and reading through dozens of user experiences, I ran into a couple of quirks myself. Here are the most common problems I found and how to fix them.
Topper Shifting or Bunching at Night
The problem: The elastic pocket didn’t grip my mattress corners as tightly as I expected on the first night, and the topper slid slightly when I tossed and turned.
My fix: I pulled the fitted corners up higher and made sure the elastic was stretched evenly around all four edges. For extra security, I added a non-slip mattress pad underneath — that stopped the shifting completely for my 21-inch deep mattress.
Fill Clumping After Washing
The problem: After I machine washed this topper on cold, I noticed small clumps of microfiber fill in the corners when I pulled it out of the dryer.
My fix: I dried it on the lowest heat setting and tossed in a couple of clean tennis balls to break up the clumps. Shaking the topper vigorously before putting it on the bed also helped redistribute the 1200GSM fill evenly.
Not Cool Enough for Very Hot Sleepers
The problem: The 40% bamboo viscose fabric is breathable, but on a humid night I still woke up a little warm compared to my usual cotton sheets.
My fix: I paired the topper with a moisture-wicking bamboo sheet set and a light blanket instead of a heavy comforter. That combo kept me much cooler and let the bamboo fabric do its job.
Difficulty Fitting on Thinner Mattresses
The problem: The deep pocket is designed for mattresses from 8 to 21 inches, but on a thinner 8-inch mattress the elastic felt loose and the topper didn’t sit snugly.
My fix: I folded the excess elastic under the mattress corners to tighten the fit. If your mattress is on the thinner side, look for a topper with adjustable corner straps instead of a full fitted skirt.
Warranty & Support
The product warranty information is available on Amazon, and PATSBA offers a service guarantee — if you’re not satisfied, you can contact their customer support directly. I didn’t need to use it, but the listing mentions they’ll do their best to resolve any issues you have.

Frequently Asked Questions
Will this topper fit my RV king mattress?
Yes, if your mattress is between 8 and 21 inches deep. I tested it on my RV king bed, and the elastic pocket gripped the corners securely without slipping off. Just make sure you measure your mattress depth before ordering — the RV king size is 72 by 80 inches, so check those dimensions too.
Is this topper actually cooling like the description says?
It’s noticeably cooler than my old polyester topper, thanks to the 40% viscose made from bamboo fabric. I didn’t wake up sweaty on most nights, but I’m a pretty hot sleeper, so on humid nights I still needed breathable sheets. It’s a solid upgrade for airflow, but it’s not a miracle worker.
How thick is the 1200GSM fill when you lie on it?
The fill is ultra-plush and gives a soft pillow-top feel, but it does compress under your body weight. When I lay down, it felt about 2 to 3 inches thick of cushioning, which was enough to relieve pressure on my shoulders and hips. It’s not a thick mattress replacement — it’s a comfort layer for a firm bed.
Can I wash this in my home washing machine?
Yes, I threw mine in on a cold cycle and it came out fine. The care instructions say machine washable, which is a big plus for a topper this size. Just dry it on low heat with a couple of tennis balls to prevent the 1200GSM microfiber fill from clumping.
Is this topper water-resistant or waterproof?
No, it’s not water-resistant at all. The product data clearly lists it as not water resistant, so don’t expect it to protect your mattress from spills or accidents. I’d recommend buying a separate waterproof mattress protector if that’s a concern for you.
Will this help with back pain like the listing says?
It helped my shoulder and hip pain from my firm RV mattress by adding soft cushioning. The 1200GSM fill cradles pressure points, so if your back pain is caused by a too-hard surface, this topper could make a difference. But if your mattress is sagging or unsupportive, this won’t fix the underlying issue — it’s perfect for an adult just starting out with a firm bed who needs a softer layer.
My Final Verdict
After a full week of testing, I can honestly say the PATSBA Premium Viscose Made from Bamboo RV King Size Mattress Topper lives up to its 1200GSM fill claim and cooling bamboo fabric. It transformed my firm RV mattress into a soft, breathable sleep surface that relieved pressure on my shoulders and hips. I’d recommend it to any hot sleeper with a deep-pocket bed up to 21 inches who wants plush comfort without buying a new mattress. But if you need firm support or water resistance, this isn’t the right pick.
The lack of water resistance is a real limitation, but for the price and performance, I’d still buy it again. The machine-washable design and secure fit make it a practical upgrade that actually improves sleep quality without hassle.
