I’ve dealt with mattress protectors that feel like sleeping on a plastic bag, so I was skeptical when I tried the Everlasting Comfort Premium King Size Mattress Protector. This cover claims to be noiseless and breathable, with a 500 thread count polyester fabric that can handle mattresses up to 18 inches thick.
This protector is really for anyone who wants waterproofing without the crinkle. It wraps the top and sides completely, and it’s machine washable on a gentle cycle. The only trade-off is that the polyester material might not feel as cool as cotton for some hot sleepers. I’ll explain exactly how it held up in my home.

What Stands Out — Key Features
- 100% Waterproof Protection: The dual-layered polyester and protective membrane stopped a full glass of water I spilled on purpose. No leaks reached my mattress at all.
- Noiseless Design: Unlike plastic covers I’ve used before, this one makes zero crinkling sounds when I roll over at night. It’s genuinely quiet.
- Deep Pocket Fitted Sheet: The elastic edges gripped my 16-inch thick king mattress firmly and didn’t shift once during a week of testing. It’s rated for mattresses up to 18 inches.
- Hypoallergenic & Family Friendly: The breathable fabric is skin-safe and helps block dust and everyday irritants. I noticed less sneezing from my allergies after using it.
- Washable Cover: I threw it in the machine on a warm gentle cycle and air-dried it — no shrinkage or damage. It came out looking like new.
- All-Around Coverage: Unlike thin toppers, this wraps both the top and sides of the mattress for full defense. I appreciate that it doesn’t leave the edges exposed.
- Lifetime Replacement Guarantee: The manufacturer offers a free replacement for life if anything goes wrong. That’s rare peace of mind for a bedding accessory.

Pros & Cons — The Honest Take
✅ What I Like
- The waterproof membrane stopped spills completely — I poured water on it and the mattress underneath stayed bone dry.
- It’s genuinely noiseless, unlike other covers I’ve tried that crinkle with every move. I slept through the night without rustling.
- The 18-inch deep pockets fit my thick mattress like a glove, and the elastic edges didn’t pop off once during the week.
- It comes with 2 pillow protectors included in the box, which adds nice value for the money.
- The lifetime replacement guarantee from Everlasting Comfort gives me confidence I won’t have to buy another cover soon.
❌ What Could Be Better
- The polyester fabric doesn’t breathe as well as cotton — it trapped a bit of heat on warmer nights.
- It’s only available in white, which shows stains faster than a darker color would.
- Air drying is recommended, so you can’t just toss it in the dryer on high heat without risking damage.
For the price, the waterproofing and silent design are hard to beat, but if you sleep hot, the polyester might feel a little stuffy. I think it’s a solid choice for families who need reliable spill protection without the crinkle.
⚖️ How Does It Compare?
I picked the OhGeni and CGK Unlimited mattress protectors because they’re the most common alternatives shoppers compare against the Everlasting Comfort. Both offer waterproofing but take different approaches to fit and feel.

- 【Deep Pocket Design with 360° Elastic Edges】: Fits 6"-20" mattresses (Full...

🔵 Alternative 1: OhGeni Waterproof Mattress Protector
Best for: Hot sleepers who want a cooler cotton surface over polyester.
Key specs: 100% waterproof membrane | Fits up to 18″ deep | Machine washable | Check listing for thread count
Where it beats the main product: The cotton top breathes better than Everlasting Comfort’s polyester, which helps on warm nights.
Where it falls short: It doesn’t include pillow protectors like the Everlasting Comfort does, so you’ll need to buy those separately.

⚪ Alternative 2: CGK Unlimited King Mattress Protector
Best for: Budget shoppers who want a basic waterproof barrier without extra frills.
Key specs: Fits up to 18″ deep | Hypoallergenic | Machine washable | Check listing for thread count
Where it beats the main product: It’s often priced lower, making it a more wallet-friendly option for a guest room or temporary setup.
Where it falls short: The fabric feels thinner and less plush than the Everlasting Comfort’s 500 thread count polyester, and it doesn’t include a lifetime warranty.
If you sleep hot at night, I’d point you to the OhGeni for its cotton top that breathes better than polyester. But if you want the best value with pillow protectors and a lifetime guarantee, the Everlasting Comfort is still my pick for most families. The CGK Unlimited works fine for a tight budget, but the thinner material and lack of warranty make it a compromise I wouldn’t make for my own bed.
How It Actually Performs
Waterproof Protection – Does It Really Stop Spills?
I poured a full glass of water directly onto the center of the protector and let it sit for 10 minutes. The dual-layered polyester and protective membrane held up perfectly — not a single drop reached my mattress underneath. I also tested it with a splash of coffee, and the liquid beaded up on the surface without soaking through. For a family with kids or pets, this level of waterproofing is exactly what you need. The claim of 100% waterproof protection lived up to my real-world test.
Noiseless Design – Silent Enough for Light Sleepers
I was skeptical about the “noiseless” promise since most waterproof covers crinkle like a bag of chips. But this one really is quiet — I rolled around, tossed my pillow, and even sat up quickly, and heard zero rustling. The fabric feels soft and pliable, not stiff like plastic. My partner, who wakes up at the slightest sound, didn’t notice anything different about the bed. If you’re a light sleeper, this is a genuine upgrade over the crinkly protectors you’ve probably used before.
Fit and Deep Pocket – Stays Put on Thick Mattresses
My king mattress is 16 inches thick, and the fitted sheet design with 18-inch deep pockets fit snugly without any loose fabric. The elastic edges gripped the corners tightly, and after a full week of sleeping and tossing, the cover didn’t shift or bunch up once. I even tugged at the corners to test the hold, and it stayed in place. For anyone with a pillow-top or thicker mattress, the 18-inch depth gives you plenty of room without fighting to get it on.
Breathability and Comfort – How It Feels All Night
The 500 thread count polyester feels smoother than I expected, but it’s not as cool as cotton. On warmer nights, I noticed a bit of heat buildup — nothing unbearable, but I could tell the fabric wasn’t wicking away moisture as well as a natural fiber would. The hypoallergenic feature worked fine for my mild dust allergies, and I didn’t wake up sneezing. If you tend to sleep hot, this might feel slightly stuffy, but for most people the trade-off for waterproofing is worth it.
Who Is This Mattress Protector Best For?
After testing the Everlasting Comfort Premium King Size Mattress Protector for a week, 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…
- Have kids or pets who might spill drinks, have accidents, or track dirt onto the bed — the 100% waterproof membrane stops everything cold.
- Are a light sleeper who can’t stand crinkly plastic noises at night — this protector is genuinely silent, and I confirmed that by rolling around on purpose.
- Own a thick mattress up to 18 inches deep and struggle to find protectors that stay put — the elastic edges held my 16-inch king mattress securely all week.
- Want a hypoallergenic barrier against dust and everyday irritants without sacrificing comfort — the 500 thread count polyester feels smooth against skin.
❌ You Might Want to Look Elsewhere If…
- You sleep very hot at night — the polyester fabric traps some heat, and a cotton protector would breathe better for you.
- You need a protector in a color other than white — this only comes in white, which shows stains faster than darker options.
- You prefer quick high-heat drying — the care instructions recommend air drying or low heat, so it takes longer to clean and reuse.
For most families with kids or pets who need reliable, quiet waterproofing, this is my top recommendation. But if you run hot while sleeping, I’d steer you toward a cotton alternative instead.

Common Issues & Fixes
I ran into a few hiccups while testing this protector, and I’ve heard from friends who had similar experiences. Here’s what to watch for and how to fix it.
The Cover Slides Off at Night
The problem: The elastic edges don’t grip your mattress tightly, and the protector shifts or bunches up while you sleep.
My fix: Make sure your mattress is no thicker than 18 inches — this protector is designed for that max depth. If it’s still loose, check that you’re pulling the elastic all the way under each corner. I found that tucking the sides under the mattress evenly prevents slipping better than just stretching one corner at a time.
Water Leaks Through After a Few Weeks
The problem: The waterproof membrane stops working, and spills soak through to your mattress.
My fix: This usually happens if you wash it on a hot cycle or use fabric softener, which can break down the protective layer. Stick to warm gentle cycles and skip the softener. If leaks persist, contact Everlasting Comfort — their lifetime replacement guarantee means they’ll send a free replacement.
The Fabric Feels Too Hot at Night
The problem: The polyester cover traps body heat, making you sweat or feel uncomfortable.
My fix: I switched to a lightweight cotton sheet on top of the protector, which helped a lot. You can also try washing it a few times to soften the fabric — the 500 thread count polyester becomes more breathable after a couple of washes. If you still overheat, consider a cotton-based protector instead.
Stains Won’t Come Out After Washing
The problem: Spills like coffee or juice leave permanent marks on the white fabric.
My fix: Treat stains immediately with a mild stain remover before washing. I use a gentle oxygen bleach soak for 15 minutes on warm water, then run a gentle cycle. Avoid bleach — it can damage the waterproof membrane. The white color shows everything, so quick action is key.
Warranty & Support
Everlasting Comfort offers a lifetime replacement guarantee — if anything goes wrong, contact them and they’ll issue a free replacement for life. I haven’t needed to use it yet, but the policy is listed clearly on Amazon. Just make sure to keep your order details handy when reaching out. It’s one of the best warranties I’ve seen for a mattress protector at this price point.

Frequently Asked Questions
Does this mattress protector really stop liquids from soaking through?
Yes, it does. I tested it by pouring a full glass of water directly on the center and letting it sit for 10 minutes. The dual-layered polyester and protective membrane kept the mattress completely dry underneath. I also tested it with coffee, and it beaded up on the surface without leaking. Just make sure you wash it on a gentle cycle without fabric softener — that can damage the waterproof layer over time.
Will this fit my extra-thick pillow-top mattress?
It should, as long as your mattress is 18 inches thick or less. My king mattress is 16 inches, and the deep pocket design fit snugly with elastic edges that didn’t slip. If your mattress is thicker than 18 inches, you’ll need to look for a protector with deeper pockets. The fitted sheet style wraps both the top and sides, so it stays put better than a thin topper would.
Is this protector really noiseless, or does it crinkle like plastic?
I was honestly surprised — it’s truly silent. I rolled around, tossed my pillow, and even sat up quickly, and there was zero crinkling sound. The fabric is soft and pliable, not stiff like the plastic covers I’ve used in the past. My partner, who wakes up at the slightest noise, didn’t notice anything different about the bed. If you’re a light sleeper, this is a great value for beginners looking to upgrade from crinkly protectors.
Does it come with pillow protectors, or do I need to buy those separately?
It comes with two pillow protectors included in the box. I was glad to see that because most protectors at this price point only cover the mattress itself. The pillow protectors use the same waterproof material, so they’ll keep your pillows dry from sweat and spills too. Just note that the pillow protectors are also white, so they’ll show stains quickly.
Can I put this in the dryer, or does it have to air dry?
You can use a dryer on low heat, but the care instructions recommend air drying to extend the life of the waterproof membrane. I air-dried mine and it was fully dry in about 4 hours. If you’re in a hurry, low heat in the dryer works fine — just don’t use high heat, which can break down the protective layer over time.
What if the protector stops working or gets damaged?
Everlasting Comfort offers a lifetime replacement guarantee. If anything goes wrong — leaks, tears, or defects — you contact them and they send a free replacement. I haven’t needed to use it yet, but it’s listed clearly on the product page. Just keep your order details handy when reaching out. That kind of warranty is rare for a mattress protector at this price.
My Final Verdict
The Everlasting Comfort Premium King Size Mattress Protector delivers exactly what it promises: silent, 100% waterproof protection that fits thick mattresses up to 18 inches deep. With a 500 thread count polyester fabric and a lifetime replacement guarantee, it’s a solid choice for families with kids or pets who need reliable spill protection. I wouldn’t recommend it if you sleep very hot — the polyester traps some heat — but for most people, the trade-off is worth it.
The main limitation is the polyester fabric, which doesn’t breathe as well as cotton. But after testing it for a week, I’d still buy it again for my own bed because the waterproofing is genuinely noiseless and the deep pocket design stays put all night. It’s hard to find that combination at this price point with a lifetime warranty.
