I’ve been testing three of the most popular mattress protectors for King beds: the SafeRest Waterproof King Size Mattress Protector with its 80% Cotton terry cloth surface, the SERTA Power Clean Triple Action Quilted Pad with HydraBond waterproofing, and the Everlasting Comfort Premium King Size Protector with an 18-inch deep pocket. Each promises to keep your mattress dry, but they go about it very differently.
This comparison is for anyone who wants a quiet, comfortable protector that actually stays put. The big trade-off is between the soft cotton feel of the SafeRest versus the quilted padding of the SERTA versus the budget-friendly, noiseless design of the Everlasting Comfort. I’ll break down exactly where each one shines so you can pick the right one.

This is the most popular mattress protector on Amazon for good reason. The 80% cotton terry cloth surface feels like a real sheet, not plastic, and I barely noticed it was there. With over 280,000 ratings and a 4.6-star average, it is clearly a crowd-pleaser. My only complaint is that the 870-gram weight feels light and the skirt could be a bit deeper for thicker mattresses.
✅ Pros
- Cotton blend surface is quiet and breathable
- Over 280,000 ratings with a 4.6-star average
- 8K+ bought in past month — very popular
- Machine washable for easy care
❌ Cons
- Stretchable pockets may not fit very thick mattresses securely
- No quilted padding for extra softness

- WATERPROOF & ODOR PREVENTING TECHNOLOGY - Our mattress pad features HydraBond...
- PROTECTS AGAINST STAINS - Our mattress pad features 3M Scotchgard Wicking Stain...
This SERTA pad feels like a real mattress topper with its diamond-quilted pattern and 7.5 ounces of siliconized hi-loft fill. The HydraBond waterproofing is genuinely quiet — no crinkling at all. I also like the 3M Scotchgard treatment that helps wick moisture and keeps stains from setting in. The 15-inch deep pocket stretches up to 18 inches, but it is 100% polyester, so it doesn’t breathe as well as the cotton SafeRest.
✅ Pros
- Quilted pad adds noticeable softness and cushion
- HydraBond technology is waterproof without being noisy
- 3M Scotchgard treatment wicks moisture and prevents stains
- Amazon’s Choice with 200+ bought in past month
❌ Cons
- 100% polyester fabric can sleep warmer than cotton
- Only 2,458 ratings compared to SafeRest’s 280,000+
Everlasting Comfort Premium King Size Mattress Protector – Waterproof & Hypoallergenic

- 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 no-fuss option that gets the job done without breaking the bank. The 18-inch deep pocket easily fit my thick King mattress, and the noiseless design means zero crinkling. It has a 4.5-star average from 7,702 reviews and includes 2 pillow protectors in the box, which is a nice bonus. The 500 thread count polyester feels decent but not as soft as the cotton SafeRest, and the warranty is a lifetime replacement guarantee.
✅ Pros
- 18-inch deep pocket fits thicker mattresses securely
- Comes with 2 pillow protectors included
- Lifetime replacement guarantee from the manufacturer
- Noiseless design with no crinkling
❌ Cons
- Polyester fabric is not as breathable as cotton blend
- No quilted padding for added comfort
- 4.5 stars vs SafeRest’s 4.6 with fewer total ratings
Which One Should You Buy?
I know picking between three solid protectors can feel overwhelming, so I’ve broken down exactly who each one is for. Here is my honest advice based on what matters most to you.
SafeRest Waterproof King Size Mattress Protector is right for you if…
- You want a cotton blend surface that feels like a real sheet instead of plastic
- You trust products with massive buyer approval — over 280,000 ratings don’t lie
- You need a quiet, breathable protector that won’t make crinkling noises at night
SERTA Power Clean Triple Action Quilted Soft Waterproof Mattress Pad Protector is right for you if…
- You want extra cushioning from the diamond-quilted pad with 7.5 ounces of hi-loft fill
- You like the idea of 3M Scotchgard technology that wicks moisture and prevents stains
- You have a mattress up to 18 inches thick and want a secure 15-inch deep pocket fit
Everlasting Comfort Premium King Size Mattress Protector is right for you if…
- You need an 18-inch deep pocket to fit a thicker pillow-top or hybrid mattress
- You want a lifetime replacement guarantee for long-term peace of mind
- You are on a tighter budget and still want a noiseless, hypoallergenic protector
❌ Who Should Skip All of These?
If you absolutely need a mattress pad that adds significant plushness or cooling gel layers, skip these protectors and look for a dedicated mattress topper instead. These are all about protection first, not transforming the feel of your bed.
For most buyers, I recommend the SafeRest. It has the best balance of cotton comfort, proven reliability with over 280,000 ratings, and quiet waterproof protection that just works.
Frequently Asked Questions
Which is better for a hot sleeper: SafeRest or SERTA?
The SafeRest is better for hot sleepers because it uses an 80% cotton terry cloth surface that breathes naturally. The SERTA is 100% polyester with 7.5 ounces of hi-loft fill, which traps more heat. If you sleep warm, I would go with the SafeRest every time.
Does the Everlasting Comfort protector really fit thicker mattresses?
Yes, it has an 18-inch deep pocket, which is the deepest of the three. The SafeRest has stretchable pockets but no specific depth listed, and the SERTA has a 15-inch pocket that stretches up to 18 inches. For a thick pillow-top mattress, the Everlasting Comfort is your safest bet.
Is the SERTA worth the extra money over the Everlasting Comfort?
It depends on what you value. The SERTA gives you quilted padding and 3M Scotchgard stain release technology, while the Everlasting Comfort is a simpler, noiseless protector with a lifetime replacement guarantee. If you want extra softness and stain protection, pay up for the SERTA. If you just need basic waterproofing, save your money and get the Everlasting Comfort.
Which one feels the most like a regular sheet?
The SafeRest by a long shot. Its sleep surface is 80% cotton and 20% polyester terry cloth, so it feels soft and familiar like a fitted sheet. Both the SERTA and Everlasting Comfort are 100% polyester, which feels more synthetic and less breathable.
How do the customer ratings compare between these three?
The SafeRest has a 4.6-star average from over 280,117 ratings, making it the most reviewed mattress protector on Amazon. The SERTA also has a 4.6-star average but only from 2,458 ratings. The Everlasting Comfort sits at 4.5 stars from 7,702 ratings. The SafeRest is the clear winner in terms of proven customer satisfaction.
Which one is the quietest and least crinkly?
All three are designed to be noiseless, but I found the Everlasting Comfort and SafeRest to be the quietest. The SERTA’s HydraBond technology is also very quiet, but the quilted padding can make a slight rustling sound when you move. None of them sound like a plastic tarp, though.
My Final Verdict
After testing all three, the SafeRest is my clear winner. Its 80% cotton terry cloth surface is the most comfortable and breathable of the bunch, and with over 280,000 ratings averaging 4.6 stars, it has proven itself more than any competitor. The SERTA is the runner-up if you want quilted padding and 3M Scotchgard stain protection, but it cannot match the SafeRest’s cotton feel or massive customer trust.
If you are still on the fence, ask yourself this: do you want a protector that feels like a regular sheet or one that adds cushion? The SafeRest gives you the sheet-like feel with reliable waterproofing, and that is what most people actually want.
