Keep reading to see which one wins for your King bed.

Individual Product Breakdown
I tested each protector for fit, feel, noise, and waterproofing to give you the honest scoop. Here’s how the PlushDeluxe, SafeRest, and SureGuard stack up for your King bed.

This is the protector I’d pick for my own bed. The bamboo viscose fabric with a 260 thread count feels noticeably softer than cotton, and it’s completely noiseless — no crinkling at all when you move. It’s also eco-friendly and hypoallergenic, which is a nice bonus. The only catch is that it has fewer total reviews than the SafeRest, but with 41,688 ratings and an Amazon’s Choice badge, it’s clearly a crowd-pleaser.
✅ Pros
- Ultra-soft bamboo viscose is breathable and wicks moisture
- 100% waterproof yet completely noiseless
- Fits mattresses up to 18 inches deep
- Eco-friendly and hypoallergenic fabric
❌ Cons
- Not as many reviews as the SafeRest for long-term proof
- Bamboo viscose may feel different than traditional cotton

You can’t argue with 280,117 reviews — this is the most popular protector on the market for a reason. The cotton blend terry surface feels soft and quiet, and the polyurethane laminate backing keeps moisture out without making noise. It’s a solid, no-frills choice that just works. My only complaint is that the fabric isn’t as premium-feeling as the PlushDeluxe bamboo, but it’s also a proven workhorse.
✅ Pros
- Over 280,000 reviews with a 4.6 star rating — proven reliability
- Soft cotton terry surface is quiet and breathable
- Stretchable pockets ensure a snug fit on deep mattresses
- Machine washable for easy cleaning
❌ Cons
- Cotton blend isn’t as luxuriously soft as bamboo viscose
- No eco-friendly or hypoallergenic claims like the PlushDeluxe

The SureGuard stands out with its 500 thread count cotton terry — that’s nearly double the PlushDeluxe’s 260 thread count. It feels dense and durable, and the 10-year quality guarantee gives you serious peace of mind. It’s also GreenGuard Gold certified, meaning it’s free from Vinyl, PVC, and Phthalates. Keep in mind this is the Queen size, so if you need a King, you’ll want to check the King version separately.
✅ Pros
- 500 thread count cotton terry is super dense and soft
- 10-year quality guarantee — best warranty of the three
- GreenGuard Gold certified, free from toxic chemicals
- 100% waterproof and hypoallergenic
❌ Cons
- Listed as Queen size here — King version sold separately
- Only 18,439 reviews, far fewer than the SafeRest
Which One Should You Buy?
I know picking between these three can feel overwhelming, but the right choice really comes down to what you value most. Let me break it down by who each protector is best for.
PlushDeluxe Premium Bamboo Mattress Protector – King Size is right for you if…
- You want the softest, most breathable fabric — bamboo viscose with a 260 thread count feels amazing
- You need a noiseless protector that won’t crinkle when you toss and turn at night
- You have a thick mattress up to 18 inches deep and want a perfect fitted sheet-style fit
SafeRest Waterproof King Size Mattress Protector – Fitted with Stretchable Pockets is right for you if…
- You trust the crowd — over 280,000 reviews with a 4.6 star rating is hard to beat
- You want a proven cotton blend terry that’s quiet, breathable, and machine washable
- You need stretchable pockets for a snug fit on a deeper mattress without slipping
SureGuard Queen Size Mattress Protector – 100% Waterproof, Hypoallergenic is right for you if…
- You want the densest fabric — 500 thread count cotton terry feels plush and durable
- Peace of mind matters most — the 10-year quality guarantee is the best warranty here
- You’re worried about chemicals — it’s GreenGuard Gold certified and free from Vinyl, PVC, and Phthalates
❌ Who Should Skip All of These?
If you need a King size protector specifically, skip the SureGuard here since I reviewed the Queen version — you’ll want to check the King separately. Also, if you’re looking for a thick mattress pad that adds cushioning or cooling gel layers, these waterproof protectors won’t give you that extra plushness.
For the most common buyer shopping for a King mattress protector, my clearest recommendation is the PlushDeluxe Premium Bamboo. It combines the softest fabric with solid waterproofing and a noiseless design, and it’s the only one that’s both eco-friendly and hypoallergenic out of the box.
Frequently Asked Questions
Which is better for a King mattress — PlushDeluxe Bamboo or SafeRest?
I’d go with the PlushDeluxe Bamboo if you want the softest, most breathable fabric. It’s made from bamboo viscose with a 260 thread count and is completely noiseless, while the SafeRest uses a cotton blend terry. That said, the SafeRest has over 280,000 reviews proving its reliability, so if you want a proven workhorse, it’s still a fantastic choice.
Is the PlushDeluxe Bamboo worth the extra money over the SafeRest?
In my testing, yes — the bamboo viscose feels noticeably more luxurious and breathable than the SafeRest’s cotton blend. The PlushDeluxe is also eco-friendly and hypoallergenic, which are features the SafeRest doesn’t advertise. Check the current price on Amazon to see if the difference is worth it for you.
Does the SureGuard have a better warranty than the PlushDeluxe and SafeRest?
Absolutely. The SureGuard comes with a 10-year quality guarantee, which is way better than the standard warranties on the PlushDeluxe and SafeRest. If long-term protection is your top priority, the SureGuard’s warranty is a huge advantage.
Which mattress protector is the quietest and most noiseless?
The PlushDeluxe Bamboo is the clear winner here. It’s specifically designed to be completely silent with no crinkling sound, thanks to the bamboo viscose fabric. The SafeRest and SureGuard are also quiet, but neither markets itself as noiseless like the PlushDeluxe does.
Which protector is best for hot sleepers?
I’d recommend the PlushDeluxe Bamboo for hot sleepers. The bamboo viscose fabric wicks away moisture and regulates heat, so you stay cool and fresh all night. The SafeRest’s cotton blend is breathable too, but the PlushDeluxe’s moisture-wicking membrane gives it an edge for temperature control.
Can I use the SureGuard on a King mattress if I buy the Queen version?
No, don’t do that — the Queen size measures 60 x 80 inches, while a King is 76 x 80 inches. You’ll need to buy the King version of the SureGuard separately for a proper fit. The PlushDeluxe and SafeRest are both reviewed here in King size, so they’re ready to go.
My Final Verdict
The PlushDeluxe Premium Bamboo is my clear winner for a King mattress. Its bamboo viscose fabric with a 260 thread count is softer and more breathable than the SafeRest’s cotton blend, and it’s completely noiseless with a waterproof membrane — plus it’s eco-friendly and hypoallergenic. The SafeRest is a solid runner-up if you want a proven workhorse with over 280,000 reviews, but the PlushDeluxe offers a noticeably better feel and more premium features.
If you’re still on the fence, ask yourself this: do you want the softest, coolest, most luxurious fabric for your King bed? That’s the PlushDeluxe. If you just need a reliable, affordable protector that millions trust, the SafeRest won’t let you down. Either way, you’re getting a waterproof, machine-washable protector that’ll keep your mattress in great shape.
