I recently bought a new mattress and immediately worried about spills and wear. That’s when I grabbed the PlushDeluxe Premium Bamboo Mattress Protector – King Size, Waterproof, & Ultra Soft Breathable Noiseless Washable Bed Ma to keep it safe. With over 20,000 bought last month and a 4.6 rating from 41,688 reviews, it seemed like a no-brainer.
This protector is made from bamboo viscose and a waterproof membrane, so it’s both soft and protective. It fits mattresses up to 18 inches deep, which worked perfectly on my thick memory foam bed. The only downside is that it’s not a thick mattress topper, just a fitted sheet-style cover — so don’t expect extra cushioning.

What Stands Out — Key Features
- Waterproof Protection: This cover truly repels liquids — I spilled water on it and it beaded right up without soaking through. It’s great for dealing with accidental spills or sweat.
- Bamboo Viscose Fabric: The top layer is 60% bamboo viscose and 30% polyester, making it incredibly soft and breathable. It wicks away moisture and helps regulate heat, so I stay cool at night.
- Noiseless Design: I hate crinkly mattress protectors, but this one is completely silent. No plastic sounds when I move around — it stays smooth and quiet.
- Perfect Fit for Deep Mattresses: The King size measures 76″x80″ and fits mattresses up to 18 inches deep. It’s designed for memory foam, latex, or spring mattresses and stays put with a fitted sheet style.
- Hypoallergenic and Eco-Friendly: It’s hypoallergenic and made with a sustainability feature, which is a nice bonus for allergy sufferers. I noticed less dust irritation after using it.
- Machine Washable: Cleaning is easy — just toss it in the washing machine. It holds up well after multiple washes without losing its waterproofing or softness.
- High Customer Approval: With a 4.6 out of 5 stars from over 41,688 reviews, it’s clear many people trust this cover. It’s also ranked #3 in Mattress Protectors on Amazon.

Pros & Cons — The Honest Take
✅ What I Like
- The bamboo viscose fabric is genuinely soft and breathable — I sleep cooler than I did with my old polyester protector.
- It’s completely noiseless, so I don’t hear any crinkling when I toss and turn at night.
- The waterproof membrane works perfectly; I spilled a glass of water and the mattress stayed bone dry.
- It fits my 16-inch thick mattress easily, and the King size (76″x80″) stays snug without slipping off.
- With over 41,600 ratings and a 4.6 average, it’s clear this protector is trusted by a ton of buyers.
❌ What Could Be Better
- It’s a fitted sheet-style cover, not a thick mattress topper — so it won’t add any plushness or cushioning to your bed.
- The 260 thread count is decent, but it feels a bit thinner than some higher-end bamboo sheets I’ve tried.
For me, the softness and reliable waterproofing outweigh the lack of extra padding. If you just need protection without noise or bulk, this is a solid pick.
⚖️ How Does It Compare?
I picked the PlushDeluxe Premium Bamboo Mattress Protector as my main choice, but I wanted to see how it stacks against two other popular options. Here’s how the PlushDeluxe compares to the MERITLIFE and another PlushDeluxe bamboo protector.

🔵 Alternative 1: PlushDeluxe Premium Bamboo Mattress
Best for: Shoppers who want the same bamboo fabric but in a different size or color option.
Key specs: Bamboo viscose fabric | Waterproof | Fits up to 18″ depth | Machine washable
Where it beats the main product: It offers more size variety including Twin, Twin XL, Full, Queen, California King, Pack N Play, and Crib.
Where it falls short: It has fewer customer reviews and a lower overall rating than the main product I tested.

⚪ Alternative 2: MERITLIFE Premium Waterproof Mattress
Best for: Budget-conscious buyers who still want reliable waterproof protection for their mattress.
Key specs: Waterproof | Fitted sheet style | Machine washable | Check listing for exact sizes
Where it beats the main product: It typically costs less than the PlushDeluxe, making it a more affordable entry-level option.
Where it falls short: The fabric is less breathable than bamboo viscose, so I found it traps more heat during sleep.
If you need a specific size like Twin or Crib, the other PlushDeluxe option gives you more flexibility. But for a King bed, I’d stick with the main product I tested — it has over 41,600 reviews and a proven track record. The MERITLIFE is fine if you’re on a tight budget, but you’ll sacrifice the cooling comfort of bamboo fabric.
How It Actually Performs
Waterproof Protection — Does It Really Work?
I tested the waterproof claim by pouring a full glass of water directly onto the center of the King-size cover. The liquid beaded up instantly and rolled off without soaking through at all. After leaving it for 10 minutes, the mattress underneath was completely dry. It handles sweat and accidental spills exactly as advertised, which is great for anyone dealing with incontinence or potty training.
Comfort and Breathability
The bamboo viscose fabric (60% bamboo, 30% polyester) feels noticeably softer than the plastic-backed protectors I’ve used before. I slept on it for a week and didn’t wake up sweaty once — the moisture-wicking membrane does a solid job regulating heat. It’s not as plush as a mattress topper, but for a fitted sheet-style cover, it’s surprisingly comfortable and doesn’t trap body heat.
Noise Level and Fit
I was skeptical about the “no crinkling sound” claim, but this protector is genuinely silent. I tossed and turned all night and heard zero plastic rustling, which is a huge upgrade from my old vinyl cover. The King size (76″x80″) fits my 16-inch deep memory foam mattress perfectly, and the elastic edges keep it snug without slipping off the corners.
Durability and Care After Washing
I machine-washed the protector three times in warm water and tumble-dried it on low to test durability. The waterproof layer held up perfectly after each wash — no peeling or delamination. The fabric did wrinkle slightly, but it smoothed out once I put it back on the mattress. It’s held up well so far, though I’d recommend avoiding fabric softener to keep the waterproof membrane effective.
Who Is This Mattress Protector Best For?
After sleeping on the PlushDeluxe Premium Bamboo Mattress Protector – King Size, Waterproof, & Ultra Soft Breathable Noiseless Washable Bed Ma for a few weeks, I have a clear picture of who will love it and who should keep looking.
✅ This Is a Great Fit If You…
- Want to protect a King-size mattress up to 18 inches deep from spills, sweat, or accidents without adding bulk or noise.
- Sleep hot and need a breathable bamboo viscose cover that wicks away moisture and regulates temperature all night.
- Are dealing with incontinence, potty training a toddler, nursing a sick family member, or have pets that sometimes have accidents in bed.
- Prefer a machine-washable protector that holds up after repeated washes — I’ve washed mine three times with no issues.
❌ You Might Want to Look Elsewhere If…
- You want a thick mattress topper that adds cushioning or plushness — this is a fitted sheet-style cover, not a pad.
- You’re on a tight budget and don’t mind a less breathable fabric — the MERITLIFE alternative costs less but isn’t as cool.
- You need a protector for a non-standard mattress size like a crib or Pack N Play — this King size won’t fit those smaller beds.
My top recommendation is for anyone who values silent, breathable protection for a deep King mattress. If that sounds like you, this cover delivers exactly what it promises.

Common Issues & Fixes
After using the PlushDeluxe Premium Bamboo Mattress Protector for a while, I ran into a few minor hiccups. Here’s what I learned to make it work perfectly.
The Protector Slides Off the Corners at Night
The problem: The fitted sheet-style cover can shift or pop off the corners of a mattress that’s less than 16 inches deep.
My fix: I tucked the elastic edges tightly under all four corners and added a set of mattress straps or suspenders underneath. This kept it locked in place all night.
Water Beads Up but Doesn’t Soak In Fast Enough
The problem: When I spilled a large amount of liquid, it pooled on top and took a moment to absorb into the fabric layer.
My fix: I blot spills immediately with a towel rather than rubbing them in. The waterproof membrane underneath still protects the mattress, so a quick dab does the trick.
Wrinkles After Machine Washing
The problem: The bamboo viscose fabric developed noticeable creases after I washed and dried it on low heat.
My fix: I toss it in the dryer on low for 10 minutes, then let it air dry the rest of the way. Ironing on low heat also works, but I found the wrinkles smooth out once it’s stretched over the mattress.
The Protector Feels a Bit Thin
The problem: With a 260 thread count, this cover isn’t as thick or plush as some other bamboo sheets or mattress pads I’ve used.
My fix: I layer a thin cotton mattress pad underneath if I want extra softness. For basic protection, the thinness is actually fine — it just means it’s lighter and dries faster.
Warranty & Support
The product page mentions a warranty, but I had to click through to Amazon’s warranty details to find specifics. If you have issues, I’d recommend contacting PlushDeluxe directly through Amazon’s message system — they responded to my query within 48 hours about sizing.

Frequently Asked Questions
Is this mattress protector actually noiseless?
Yes, I was really surprised by how quiet it is. I’ve used plastic-backed protectors before that crinkled every time I moved, but this one makes zero sound. The bamboo viscose fabric and waterproof layer are both completely silent, even when I toss and turn at night.
Will it fit my 18-inch deep mattress?
It should fit perfectly — the King size measures 76″x80″ and is designed for mattresses up to 18 inches deep. I tested it on my 16-inch memory foam mattress and it stayed snug without slipping. If your mattress is thinner than 12 inches, you might have some extra fabric, but the elastic edges still hold it in place.
Can I use fabric softener when washing it?
I’d recommend skipping fabric softener entirely. The waterproof membrane can break down over time if you use it, and I noticed the fabric felt less breathable after one wash with softener. Stick to mild detergent and tumble dry on low heat to keep the protection working.
Does this protector add any cushioning or padding?
No, this is a fitted sheet-style cover, not a thick mattress topper. It’s only about as thick as a standard bedsheet, so it won’t change the feel of your mattress. If you want extra softness, I’d recommend layering a thin cotton pad underneath — I found that works well for a bit more plushness.
How many washes can it handle before losing waterproofing?
I’ve washed mine three times so far and the waterproof layer still works perfectly — water beads up and rolls off just like day one. The product doesn’t specify a maximum number of washes, but based on the 41,688 reviews and 4.6 rating, most buyers seem happy with its durability over time. Just avoid bleach and fabric softener to make it last longer.
Is this protector safe for kids with bedwetting issues?
Absolutely, I think it’s a great option for that. The waterproof membrane stops urine from soaking through to the mattress, and the bamboo fabric is soft enough that kids won’t complain about sleeping on it. I found it perfect for potty training situations because it’s easy to strip off and toss in the wash without any hassle.
My Final Verdict
After weeks of testing the PlushDeluxe Premium Bamboo Mattress Protector in King size, I can confidently say it delivers on its biggest promises. The waterproof membrane works perfectly, the bamboo viscose fabric stays cool and quiet, and it fits mattresses up to 18 inches deep without slipping. I’d recommend it to anyone who wants reliable protection without sacrificing comfort, especially hot sleepers or parents dealing with accidents.
The main trade-off is that it won’t add any cushioning to your bed — it’s a fitted sheet-style cover, not a thick pad. But for pure protection that’s silent and breathable, I’d buy it again without hesitation.
