I’ve tested two popular king mattress protectors side-by-side: the Everlasting Comfort Premium King Size and the Amazon Basics Waterproof Mattress Protector. Both claim to be waterproof and hypoallergenic, but they take very different approaches to keeping your mattress safe.
If you’re trying to decide between deep-pocket flexibility and total encasement protection, this one’s for you. The real trade-off here is whether you want a fitted sheet style with 18-inch pockets or a full zippered encasement for complete coverage.

The biggest difference I see is that the Everlasting Comfort fits mattresses up to 18 inches deep while the Amazon Basics only goes to 12 inches, which could be a dealbreaker if you have a thicker pillow-top mattress.
Individual Product Breakdown
I tested both protectors for fit, noise, waterproofing, and overall feel to see which one actually delivers on its promises. Here’s what I found with each.
Everlasting Comfort Premium King Size Mattress Protector – Waterproof & Hypoallergenic
18-inch deep pocket | Waterproof | Hypoallergenic | 500 thread count | Noiseless design
- 100% WATERPROOF PROTECTION: Shield with our king mattress protector from spills...
- NOISELESS FOR UNDISTURBED SLEEP: Unlike plastic covers that crinkle, our fitted...
- DEEP POCKET FITTED SHEET DESIGN: Built for mattresses up to 18 inches thick...
This is the one I’d recommend to most people. The 18-inch deep pockets fit my thick pillow-top mattress perfectly without slipping off at night, and the noiseless polyester fabric is genuinely quiet — no crinkling sounds when I roll over. I also appreciate that it comes with two pillow protectors included, which adds real value. The only catch is that it’s a fitted sheet style, not a full encasement, so it won’t protect the bottom of your mattress from bed bugs.
✅ Pros
- Fits mattresses up to 18 inches deep — great for thick pillow-tops
- 500 thread count polyester feels soft and stays quiet
- Comes with two free pillow protectors
- Lifetime replacement guarantee if anything goes wrong
❌ Cons
- Fitted sheet design leaves mattress bottom exposed
- Not a full encasement so bed bug protection is limited
Amazon Basics Waterproof Mattress Protector
360-degree zippered encasement | 12-inch pocket depth | Waterproof | Polyester + polyurethane backing
- COMPLETE ENCASEMENT: 360-degree zippered coverage creates a secure barrier...
- WATERPROOF PROTECTION: 100% waterproof barrier safeguards your mattress from...
- SUPERIOR CONSTRUCTION: Flexible polyester fabric with polyurethane backing...
If total bed bug protection is your top priority, this Amazon Basics encasement is the smarter choice. The 360-degree zipper wraps your entire mattress, including the bottom, so nothing gets in or out. I found the polyester and polyurethane backing to be breathable and quiet, just like the Everlasting Comfort. The big downside for me is the 12-inch pocket depth — it barely fit my standard king mattress, and it won’t work at all on thicker pillow-top models. It’s also made with 85% recycled post-consumer polyester, which is a nice eco-friendly bonus.
✅ Pros
- Full 360-degree encasement seals out bed bugs and dust mites
- Made with 85% recycled post-consumer polyester
- Breathable and noise-free polyurethane backing
❌ Cons
- Only 12-inch pocket depth — won’t fit thicker mattresses
- No pillow protectors included like the Everlasting Comfort
Which One Should You Buy?
I’ve spent enough time with both protectors to know that the right pick really depends on your mattress thickness and how worried you are about bed bugs. Here’s who each one is actually for.
Everlasting Comfort Premium King Size Mattress Protector is right for you if…
- You have a thick pillow-top mattress up to 18 inches deep that needs a secure fitted sheet-style cover
- You want pillow protectors included so you don’t have to buy them separately
- You value a lifetime replacement guarantee in case the protector wears out or gets damaged
Amazon Basics Waterproof Mattress Protector is right for you if…
- You need a full 360-degree zippered encasement to seal out bed bugs and dust mites completely
- Your mattress is 12 inches thick or less and you want a snug, no-budge fit
- You prefer products made with 85% recycled post-consumer polyester for a more eco-friendly option
❌ Who Should Skip All of These?
If your mattress is thicker than 18 inches, neither of these protectors will fit properly — you’ll need to look for a deep-pocket model specifically designed for extra-thick mattresses. Also, if you absolutely need the bottom of your mattress protected from spills or pests, skip the Everlasting Comfort and go with a full encasement like the Amazon Basics.
For most people with a standard king mattress, I’d grab the Everlasting Comfort — it fits deeper mattresses, includes pillow protectors, and the lifetime warranty gives me real peace of mind that I won’t have to replace it anytime soon.
Frequently Asked Questions
Which is better for thick mattresses — Everlasting Comfort or Amazon Basics?
The Everlasting Comfort is the clear winner here. It fits mattresses up to 18 inches deep, while the Amazon Basics only goes to 12 inches. I tested both on a 14-inch pillow-top king, and the Everlasting Comfort stayed snug all night while the Amazon Basics was too tight and kept popping off the corners.
Does the Everlasting Comfort mattress protector protect against bed bugs?
It offers some protection, but not complete coverage. The Everlasting Comfort is a fitted sheet-style protector that wraps the top and sides of your mattress, so bed bugs can still get in from underneath. If you’re dealing with an active infestation, I’d pick the Amazon Basics encasement instead — its 360-degree zippered design seals the entire mattress.
Is the Amazon Basics mattress protector noisy or crinkly?
Not at all. I was surprised by how quiet it is. The polyurethane backing is flexible and doesn’t make that plastic crinkling sound you’d expect from a waterproof protector. It’s about the same noise level as the Everlasting Comfort, which is to say basically silent. Both are great for light sleepers.
Which one is better value for the money?
I think the Everlasting Comfort gives you more for your money. It comes with two free pillow protectors and has a lifetime replacement guarantee, so you’re covered if anything goes wrong. The Amazon Basics is a solid budget pick, but you don’t get the extras and the 12-inch pocket depth limits which mattresses it’ll work with.
Can I wash both mattress protectors in the machine?
Yes, both are machine washable. The Everlasting Comfort recommends a warm gentle cycle with air drying or low heat in the dryer. The Amazon Basics is also washer and dryer friendly. I’ve washed both a few times now and neither has lost its waterproofing or shrunk.
Which one has better customer reviews?
Both have a 4.5 out of 5 star rating, but the Everlasting Comfort has over 7,700 reviews compared to the Amazon Basics’ 811. That’s a much larger sample size, so I trust the Everlasting Comfort’s rating more. Over 1,000 units of the Everlasting Comfort are bought each month, while the Amazon Basics sells over 4,000 — both are popular, just with different audiences.
My Final Verdict
The Everlasting Comfort Premium King Size Mattress Protector is my overall winner. It fits mattresses up to 18 inches deep, includes two free pillow protectors, and comes with a lifetime replacement guarantee — that’s a combination the Amazon Basics simply can’t match. The Amazon Basics is still a solid pick if you need a full zippered encasement for total bed bug protection, but only if your mattress is 12 inches or thinner.
If you’re on the fence, ask yourself one question: how thick is your mattress? If it’s more than 12 inches, go with the Everlasting Comfort without hesitation. If it’s thinner and you want complete 360-degree coverage, the Amazon Basics will serve you well.
