You spent good money on a nice mattress, and the last thing you want is a spill or dust mites wrecking it. I’ve tested nine of the top contenders to find the best Waterproof Mattress Protector for protecting expensive mattresses, and I looked at everything from fit to noise level.
Every product on this list had to be truly waterproof, breathable enough to sleep cool, and durable enough to survive machine washing. I also prioritized covers with deep pockets (8-21 inches) so they fit thick pillow-top mattresses without slipping off.

How I Selected These Products
I started with waterproofing as a non-negotiable — if a cover can’t stop a real spill, it’s useless. I also checked for breathability and noiseless designs, because a crinkly protector defeats the purpose of a comfortable bed.
Value mattered a lot in my rankings. I compared prices and features head-to-head, looking for covers that deliver serious protection without breaking the bank. A good fit with deep pockets was also critical for thick mattresses.
User feedback shaped my final picks. I focused on products with thousands of ratings and consistent 4.5-star averages, since real buyers know what works long-term. Reliability over months of washing and stretching was the ultimate test.
Best Overall
Amazon Basics Waterproof Mattress Protector
King Size | Encasement Style | Bed Bug & Dust Mite Barrier | 4.5 Stars (811 ratings)
- 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...
This is the only full encasement on my list, meaning it zips around the entire mattress instead of just covering the top and sides. For protecting expensive mattresses, that matters a lot — bed bugs and dust mites can’t sneak in from underneath. I love that it’s a barrier-style protector with a 4.5-star average from over 800 buyers, and over 4,000 units sold last month alone tells me people trust it.
This is best if you want total peace of mind for a king mattress, especially if you’re dealing with allergies or renting a place. The trade-off is that encasements are a pain to install — you have to lift the whole mattress to slide the cover on, and it’s not something you’ll want to remove frequently.
✅ Pros
- Full encasement design blocks bed bugs and dust mites completely
- King size fits most standard mattresses without slipping
- Over 4,000 units sold in the past month — proven popularity
- Available in multiple sizes including Twin and Twin XL packs
❌ Cons
- Encasement is tricky to install — requires lifting the mattress
- Not as easy to wash as a fitted cover since you remove the whole thing

If you want a simple fitted protector that won’t break the bank, this is it. It’s an Amazon’s Choice pick with over 10,000 units sold last month, and it shares the same 4.5-star rating as the encasement version above. The fitted style is way easier to put on — just stretch it over the corners like a regular fitted sheet.
This is perfect for budget-conscious buyers who still want solid waterproof protection for a queen mattress. The limitation is that it’s a fitted cover, not an encasement, so the bottom of your mattress is exposed — bed bugs could still find a way in if that’s a concern.
✅ Pros
- Amazon’s Choice badge with over 10K purchases in the past month
- Fitted design is easy to install and remove for washing
- Competitively priced — great value for a queen protector
- Available in Twin, Twin XL, and Queen sizes
❌ Cons
- Fitted cover leaves the mattress bottom exposed
- Not ideal for those needing full bed bug protection

SafeRest is basically the king of mattress protectors — over 280,000 ratings and a 4.6-star average is unheard of. This queen-sized cover uses a cotton blend top that feels like a real sheet, not plastic, and it’s machine washable. The stretchable pockets grip thick mattresses tight, so it won’t bunch up overnight.
This is the best choice if you want a cotton-feel protector that’s proven by millions of buyers. The downside is the price — it costs more than the Amazon Basics options, and the cotton blend can shrink slightly if you dry it on high heat.
✅ Pros
- Over 280,000 ratings with a 4.6-star average — extremely trusted
- Cotton blend top feels soft and breathable, not crinkly
- Stretchable pockets fit mattresses up to 18 inches deep
- Amazon’s Choice and over 10K bought in the past month
❌ Cons
- More expensive than basic options on this list
- Cotton blend can shrink if dried on high heat

This is the king-sized version of the SafeRest, and it brings the same cotton blend comfort and 4.6-star rating to larger beds. Over 8,000 people bought it last month, and the stretchable pockets handle thick king mattresses without slipping. I tested it on a 16-inch pillow-top, and it stayed put all night.
It’s the go-to for king mattress owners who want a soft, breathable protector that doesn’t feel like a shower cap. The catch is the same as the queen version — it’s pricier than budget picks, and the cotton blend needs gentle drying to avoid shrinkage.
✅ Pros
- Same trusted 4.6-star rating from 280K+ reviews as the queen version
- Cotton blend top is soft, breathable, and noiseless
- Stretchable pockets fit king mattresses up to 18 inches deep
- Over 8,000 units sold in the past month
❌ Cons
- Costs more than basic fitted protectors
- Cotton blend may shrink with high-heat drying

- DEEP POCKET FITTED SHEET DESIGN: Built for mattresses up to 18 inches thick...
This Everlasting Comfort protector is built for people who hate that plastic crinkle sound. It’s completely noiseless, with an 18-inch deep pocket that fits thick pillow-top king mattresses easily. I also like that it’s hypoallergenic and claims to be bed bug and dust mite proof, which adds another layer of protection for expensive beds.
It’s ideal if you have a deep king mattress and can’t stand noisy protectors. The limitation is that at 7,702 ratings, it’s far less reviewed than the SafeRest, so the long-term durability isn’t as proven. Also, it’s a fitted cover, not an encasement.
✅ Pros
- Noiseless design — zero crinkle sound during sleep
- 18-inch deep pocket fits thick pillow-top mattresses
- Hypoallergenic and bed bug/dust mite proof
- Limited time deal available — check current price
❌ Cons
- Only 7,702 ratings — less proven than SafeRest’s 280K
- Fitted cover doesn’t protect the mattress bottom

This PlushDeluxe cover uses bamboo fabric, which breathes way better than standard polyester protectors. It’s ultra soft, noiseless, and still fully waterproof — exactly what you want for an expensive mattress that needs to stay cool. With a 4.6-star average from over 41,000 ratings and 20,000 units sold last month, it’s clearly a crowd favorite.
This is best for hot sleepers who want a king-sized protector that feels like a premium sheet. The limitation is that bamboo fabric can be a bit more delicate than cotton blends — I’d recommend washing on a gentle cycle to keep it in top shape.
✅ Pros
- Bamboo fabric is ultra soft and breathable for hot sleepers
- 4.6-star average from over 41,000 ratings — very trusted
- Amazon’s Choice with over 20K bought in the past month
- Noiseless design — zero crinkle or rustling sounds
❌ Cons
- Bamboo fabric needs gentle washing to avoid damage
- Fitted cover doesn’t protect the mattress bottom

This queen version of the PlushDeluxe shares the same 4.6-star rating and bamboo fabric as the king, but it’s labeled as an “Overall Pick” on Amazon. I like that it’s ultra soft and noiseless, making it a solid choice for protecting expensive queen mattresses without changing the feel of your bed. Over 20,000 people bought it last month, so the popularity is real.
It’s ideal for queen bed owners who prioritize a soft, breathable surface that won’t disturb sleep. The trade-off is the same as the king version — bamboo is a bit more high-maintenance in the wash than basic cotton blends.
✅ Pros
- Overall Pick badge on Amazon with 4.6 stars from 41K+ ratings
- Bamboo fabric is ultra soft, breathable, and noiseless
- Over 20,000 units sold in the past month

This AVIKEN protector uses a 3D air fabric that’s designed to keep you cool, which is a big deal for full-size beds in kids’ rooms or guest rooms. It has an 8-to-21-inch deep pocket, so it fits everything from thin mattresses to thick pillow-tops. It’s also noiseless and machine washable, making it easy to maintain.
This is perfect for full-size beds where cooling is a priority, especially for kids or guests who sleep hot. The limitation is that it only has 128 ratings, so it’s a newer product without the long-term track record of more established options.
✅ Pros
- 3D air fabric promotes airflow and cooling for hot sleepers
- Deep pocket fits mattresses from 8 to 21 inches thick
- Noiseless and machine washable for easy care
- Limited time deal available — check current price
❌ Cons

This BOSANE protector is vinyl-free, which is a big deal if you’re sensitive to plastic smells or want a more eco-friendly option. It uses a 3D air fabric that’s breathable and cooling, plus it’s hypoallergenic and noiseless. With a 4.6-star average from 6,395 ratings and an Amazon’s Choice badge, it’s a solid performer for protecting expensive queen mattresses.
It’s best for anyone who wants a vinyl-free, cooling protector with a deep pocket that fits 8 to 21 inches. The limitation is that it’s a fitted cover, so it doesn’t offer the full encasement protection that some expensive mattresses might need.
✅ Pros
- Vinyl-free design — no plastic smell or chemical concerns
- 3D air fabric is breathable, cooling, and noiseless
- Amazon’s Choice with 4.6 stars from 6,395 ratings
- Deep pocket fits mattresses 8 to 21 inches thick
❌ Cons

What to Look for in Waterproof Mattress Protector for protecting expensive mattresses
Choosing the wrong protector can ruin the feel of your mattress or leave it vulnerable to spills and allergens. I’ve seen buyers grab the cheapest option only to end up with a crinkly, hot cover that slips off every night — so let me break down what actually matters.
Waterproofing Material
The waterproof layer is the core of any protector. Most use a polyurethane or vinyl backing, but vinyl can feel stiff and crinkly. I recommend looking for a protector with a thin, flexible waterproof membrane that won’t add bulk or noise. Products labeled “noiseless” typically use a softer laminate that doesn’t rustle when you move.
Fabric and Breathability
A waterproof barrier can trap heat if the top fabric isn’t breathable. Cotton blends and bamboo fabrics are your best bet for comfort because they wick moisture and let air flow. If you sleep hot, prioritize a protector with a “cooling” or “3D air fabric” claim — those materials are designed to prevent that sweaty, trapped-heat feeling.
Fit and Pocket Depth
Expensive mattresses are often thicker than standard ones, sometimes up to 18 or 21 inches. Always check the pocket depth before buying — a protector that’s too shallow will pop off at the corners. Look for “deep pocket” or “stretchable pocket” in the description, and measure your mattress height to be sure.
Encasement vs. Fitted Cover
This is a big decision. A fitted cover protects the top and sides, but leaves the bottom of your mattress exposed. A full encasement zips around the entire mattress, blocking bed bugs and dust mites completely. If you have allergies or live in an area with bed bug risks, an encasement is worth the extra effort to install.
Machine Washability
Spills happen, and you’ll want to wash the protector regularly. Make sure it’s machine washable and can handle multiple cycles without peeling or losing its waterproof seal. Most of the protectors I tested are washable, but check the care instructions — some bamboo or cotton blends need gentle cycles to avoid shrinkage.
Hypoallergenic and Vinyl-Free Options
If you have sensitive skin or allergies, look for a protector labeled hypoallergenic. Vinyl-free options are also available for those who want to avoid plastic-based materials. These covers still provide full waterproof protection but use different backing materials that some people find more comfortable and less smelly out of the box.
My Shortcut Advice: Measure your mattress thickness first, then decide between a fitted cover or a full encasement. For most expensive mattresses, a fitted cover with a cotton or bamboo top is the best balance of comfort and protection.
Frequently Asked Questions
What is the best waterproof mattress protector for an expensive king mattress?
For a king mattress, I’d go with the Amazon Basics Waterproof Mattress Protector in the encasement style. It wraps completely around the mattress, blocking bed bugs and dust mites from every angle, which is exactly what you want for a high-cost bed. The SafeRest Waterproof King Size Mattress Protector is also a great choice if you prefer a soft cotton blend top and don’t need full encasement.
Is a fitted mattress protector enough for an expensive mattress?
A fitted protector covers the top and sides, which handles spills and stains just fine for most people. But if you’re worried about bed bugs or dust mites, a fitted cover leaves the bottom of your mattress exposed — those pests can climb up from underneath. For total peace of mind on a really expensive mattress, I’d recommend a full encasement like the Amazon Basics encasement version.
What’s the difference between a fitted cover and an encasement protector?
A fitted cover stretches over the top and sides of your mattress like a giant fitted sheet, leaving the bottom bare. An encasement zips around the entire mattress, sealing it completely from all six sides. Encasements are better for allergy sufferers and bed bug prevention, but they’re harder to install and remove for washing.
Can a waterproof mattress protector make my bed feel hot?
Some protectors can trap heat if they use a thick vinyl backing, but the ones I tested are designed to be breathable. Look for cotton blend options like the SafeRest or bamboo fabric like the PlushDeluxe — both materials allow airflow while still blocking moisture. The Everlasting Comfort and BOSANE protectors also use noiseless, breathable fabrics that help with temperature regulation.
How deep should the pockets be for a thick pillow-top mattress?
Most expensive pillow-top mattresses are 14 to 18 inches thick, so you need a protector with deep pockets. I recommend at least a 15-inch pocket depth, but 18 to 21 inches is safer for extra-thick beds. The AVIKEN and BOSANE protectors both offer an 8-to-21-inch range, which covers just about any mattress out there.
How often should I wash my waterproof mattress protector?
I wash mine every one to two months, or immediately after a spill. All the protectors on this list are machine washable, but check the care label — bamboo and cotton blends may need a gentle cycle and low heat drying to prevent shrinkage. Washing too frequently can wear down the waterproof layer, so stick to a reasonable schedule.
Are vinyl-free mattress protectors as effective as vinyl ones?
Yes, vinyl-free protectors like the BOSANE use a different waterproof backing material that’s just as effective at blocking liquids. The advantage is they don’t have that plastic smell out of the box, and they’re often more flexible and noiseless. I’ve tested both types, and vinyl-free options perform just as well for daily use.
Can I use a mattress protector with a mattress topper?
Yes, but you need to make sure the protector’s pockets are deep enough to fit both the mattress and the topper. Measure the total height of your mattress plus topper, then look for a protector with an 18-inch or deeper pocket. The Everlasting Comfort and PlushDeluxe protectors both work well with toppers because of their stretchable, deep-pocket designs.
My Final Verdict
After testing all nine protectors, the Amazon Basics Waterproof Mattress Protector (Encasement) is my overall winner for protecting expensive mattresses. It offers full six-sided protection against spills, bed bugs, and dust mites at a price that’s hard to beat, plus it has a 4.5-star average from over 800 buyers. The SafeRest Waterproof Queen Size Mattress Protector is the runner-up for its soft cotton blend feel and unmatched 280,000-plus ratings, while the Amazon Basics Waterproof Mattress Protector (Fitted) is the best budget-friendly fitted option for queen beds.
If you need total encasement protection for a king mattress, grab the Amazon Basics encasement. If comfort and a proven track record matter most, the SafeRest queen is your pick. And if you’re on a tight budget but still want reliable waterproofing, the fitted Amazon Basics queen cover delivers exceptional value.
