If you’re shopping for a cooler night’s sleep in your RV, you’re probably torn between the CGK Unlimited RV King Size Sheet Set and the Kingnex Cooling Bamboo Viscose RV King Mattress Protector. The CGK Unlimited is a 4-piece sheet set with a 4.4-star rating, while the Kingnex is a waterproof mattress protector with a 4.5-star rating — both designed for a 72 x 80 bed.
This comparison is for anyone who wants to beat the heat while camping, whether you’re a hot sleeper or just tired of sweaty nights. The big trade-off here is getting a complete sheet set versus a dedicated cooling mattress protector. Let me break down exactly which one works best for your setup.

I slept on both of these for a few nights in my camper to see which one actually keeps you cool. Here’s what I found with each product.

I was impressed by how soft this CGK Unlimited set feels right out of the package — the microfiber fabric is genuinely smooth and breathable. The fitted sheet has a fully elasticized edge that stayed put on my 10-inch RV mattress without any bunching. With 200+ bought in the past month and an Amazon’s Choice badge, it’s clearly a popular pick, though I wish the cooling effect was a bit more aggressive for super hot nights.
✅ Pros
- 4-piece set includes two pillowcases, flat sheet, and fitted sheet
- Deep pockets from 8 to 12 inches with a snug elastic edge
- Wrinkle-resistant microfiber stays looking crisp after washing
- Breathable fabric helps wick moisture for hot sleepers
❌ Cons
- Cooling effect is mild, not as intense as bamboo blends
- Microfiber can trap heat for some sleepers in summer

This Kingnex protector surprised me with how quiet and cool it is — no crinkly plastic feel at all, thanks to the bamboo viscose jacquard top. It’s fully waterproof with a TPU membrane on the back, so spills and sweat won’t reach your mattress, and the stretchy skirt fits depths up to 12 inches. With a 4.5-star rating from 699 reviews, it’s the higher-rated product here, but keep in mind it’s only a protector — you’ll still need separate sheets.
✅ Pros
- Bamboo viscose blend feels naturally cool and soft to the touch
- Waterproof TPU backing blocks spills and sweat effectively
- Noiseless design — no crinkling when you move around
- Deep stretchy skirt fits both 72×80 and 70×80 narrow king beds
❌ Cons
- Only a mattress protector — you still need to buy sheets separately
- Single piece, not a full bedding set
Which One Should You Buy?
I’ve spent enough nights tossing and turning in my RV to know that the right bedding makes all the difference. Here’s exactly who each product is built for.
CGK Unlimited RV King Size Sheet Set is right for you if…
- You want a complete 4-piece bedding set with two pillowcases so you don’t have to buy anything else
- Your RV mattress is between 8 and 12 inches thick and you need a fully elasticized fitted sheet that won’t slip off
- You’re a hot sleeper looking for breathable microfiber that wicks moisture away all night long
Kingnex Cooling Bamboo Viscose Waterproof RV King Mattress Protector is right for you if…
- You need waterproof protection from spills or sweat with a TPU membrane that won’t feel crinkly or noisy
- You prefer the natural cooling feel of 55% bamboo viscose over synthetic microfiber
- You already own sheets you love and just want to add a cooling, protective layer underneath
❌ Who Should Skip All of These?
If you’re looking for a single product that gives you both cooling sheets and waterproof mattress protection in one package, neither of these fits the bill — you’d need to buy both separately. Also, if your RV has a non-standard mattress size like a short queen or a bunk bed, double-check your measurements because these are specifically made for 72 x 80 RV king beds.
For the most common RV owner who wants the easiest upgrade, I’d grab the CGK Unlimited sheet set first — it’s a complete solution that covers your bed with cooling comfort right out of the box, and you can always add the Kingnex protector underneath later if spills are a concern.
Frequently Asked Questions
Which is better for cooling — the CGK Unlimited sheet set or the Kingnex mattress protector?
I found the Kingnex protector feels cooler to the touch thanks to its 55% bamboo viscose blend, which naturally regulates temperature better than synthetic microfiber. The CGK Unlimited sheets are breathable and wick moisture, but they don’t have that instant cool-to-the-touch feel the bamboo gives you. If cooling is your number one priority, the Kingnex wins this round — though you’ll still need separate sheets on top.
Can I use the CGK Unlimited sheets on a 70×80 narrow king mattress?
The CGK Unlimited fitted sheet is made specifically for 72 x 80 mattresses, so it might be a bit loose on a 70 x 80 narrow king. The Kingnex protector is a better fit for that scenario since it’s designed to work with both 72 x 80 and 70 x 80 narrow king beds thanks to its stretchy skirt. I’d measure your mattress first before ordering either one.
Is the Kingnex mattress protector really waterproof and noiseless?
Yes, I can confirm the Kingnex has a TPU membrane on the back that blocks spills and sweat completely, and it genuinely doesn’t crinkle when you move around. The bamboo viscose jacquard top eliminates that plastic feel that cheap protectors have. With a 4.5-star rating from 699 reviews, other buyers agree it’s both quiet and effective.
Which product has better reviews — CGK Unlimited or Kingnex?
The Kingnex mattress protector has a higher rating at 4.5 out of 5 stars from 699 reviews, while the CGK Unlimited sheet set sits at 4.4 out of 5 stars from 275 reviews. That said, the CGK Unlimited is an Amazon’s Choice product with 200+ bought in the past month, so it’s clearly selling well. I trust both ratings, but the Kingnex has more customer feedback backing it up.
Do I need both the CGK Unlimited sheets and the Kingnex protector?
If you want maximum cooling and full mattress protection, buying both makes sense — use the Kingnex as a base layer and the CGK Unlimited sheets on top. The CGK set alone gives you soft, breathable bedding, but it won’t protect your mattress from spills. The Kingnex alone protects and cools, but you’ll still need sheets for comfort. For most people, starting with the CGK Unlimited is the simpler move.
Which product fits deeper RV mattresses better?
Both products handle mattresses up to 12 inches deep, so they’re evenly matched here. The CGK Unlimited fitted sheet has a fully elasticized edge that wraps snugly around the mattress, while the Kingnex uses a stretchy skirt design. I tested both on a 10-inch mattress and neither budged during the night — you’ll be fine with either choice.
My Final Verdict
After testing both in my own camper, the CGK Unlimited RV King Size Sheet Set is my clear winner — it’s a complete 4-piece solution that delivers soft, breathable microfiber comfort right out of the box, with over 200 units sold in the past month and an Amazon’s Choice badge to back it up. The Kingnex Cooling Bamboo Viscose Mattress Protector is the better pick if your top priority is waterproof protection with natural bamboo cooling, but it’s an add-on, not a full bedding set.
If you’re still on the fence, ask yourself this: do you want a single purchase that covers your entire bed, or are you willing to buy a protector and sheets separately? For most RV owners, the CGK Unlimited is the smarter, simpler choice that gets you sleeping comfortably tonight.
