5 Best Waterproof Mattress Toppers and Protectors on Amazon
The best waterproof mattress topper is a fitted cover that pairs a thin, breathable waterproof layer with a soft top fabric and pockets deep enough for your mattress. For most beds, the SafeRest Waterproof Mattress Protector is the safest all-around pick. Choose the Bedsure pillow top if you want extra cushioning along with protection. Choose the Casper protector if crinkly noise bothers you, and Utopia Bedding if budget comes first. Choose the Protect-A-Bed encasement if you want every side of the mattress sealed.
The trouble is that listings blur three different products together. Toppers, protectors and pads are all sold as "waterproof," yet many toppers soak up liquid like a sponge, and some protectors crinkle, trap heat or creep off the corners overnight. One urine accident or one spilled drink can ruin a mattress that cost hundreds of dollars, and foam is very hard to dry out once liquid reaches it.
This guide explains what each product type really does, ranks five options sold on Amazon, and shows you how to choose for your sleep habits, from hot sleepers to kids and older adults. Better Home Vibes covers sleep essentials because a protected mattress is one of the cheapest ways to keep a good night's sleep for years.
Are mattress toppers waterproof?
Most mattress toppers are not waterproof. Memory foam, latex and fiber-fill toppers absorb liquid, and a topper only blocks it when the listing names a waterproof membrane or backing. If you want a topper that protects, you need that layer built in, or you need a protector over or under the topper.
Topper, protector, pad and encasement compared
Shoppers use these words interchangeably, and that is where most bad buys start. The table separates them by job.
Product | What it adds | Waterproof? | Best for |
|---|---|---|---|
Waterproof topper | Cushioning plus a barrier | Only when the listing says so | Softening a firm bed while protecting it |
Protector | A thin barrier, almost no change in feel | Yes, if labeled waterproof | Spills, urine, sweat |
Mattress pad | Light quilted padding | Sometimes | Mild comfort, light protection |
Zippered encasement | A barrier on all six sides | Often | Allergies, bed bugs, heavy-duty protection |
Search results for a waterproof topper mostly return protectors, and that is fine. A protector costs less than a topper, barely changes how the bed feels, and does the protecting. A topper only makes sense when you also want the bed to feel different.
Buy a protector for protection and a topper for comfort, and only buy a combined product when you want both from one layer.
Can you get a waterproof topper?
Yes, you can. Brands such as Bedsure sell pillow top toppers with a waterproof layer built in, so one product softens the bed and guards it. The trade-offs are added height and added warmth, since a cushioned layer over a waterproof film holds more heat than a thin protector.
If your mattress already feels right, skip the topper and buy a protector. If your bed is too firm and you also want protection, a waterproof topper saves you from stacking two layers. Whatever you pick, check that the waterproofing sits across the whole top surface and not only in a center panel.
1. SafeRest Waterproof Mattress Protector
How it works
The SafeRest Waterproof Mattress Protector is a fitted, sheet-style cover with stretchable pockets, so it pulls over the corners of your mattress like a fitted sheet. Its waterproof backing helps protect against fluids, urine and perspiration, and the cover is machine washable. That is what most households need, and nothing more.
Because the whole top surface is sealed, a spilled drink beads up instead of soaking in. A fitted protector covers the top and the sides down to the pocket line but not the underside, which suits accidents that happen on top of the bed.
A good protector is invisible until the night you need it.
Who it suits
Pick this one if you want a dependable, no-fuss layer for an adult bed, a child's bed or a guest room. It is the most sensible default when you have no special requirement such as allergies or a very tall mattress.
Best for: everyday protection in any bedroom, from spills to night-time accidents
Watch for: pocket depth against your mattress thickness, and a little extra warmth if you sleep hot
Price
SafeRest sits in the budget to mid range, typically around $30 to $50 for a queen, though Amazon prices move with size and sales.
At that cost, buying a second cover makes sense, so you can swap in a clean one while the first is in the wash.
2. Bedsure Waterproof Pillow Top Mattress Topper
How it works
The Bedsure Waterproof Pillow Top Mattress Topper adds a plush quilted layer with a waterproof barrier, so one product does both jobs. The brand describes it as breathable and gentle on sensitive skin. Treat "breathable" as relative, because any waterproof layer holds more heat than a plain cotton topper.
Since it adds thickness, check two things before you order. Compare the topper's pocket depth with your mattress, and compare your fitted sheet depth with the new total height. A thicker bed needs deep-pocket sheets, and a topper that is too shallow lifts at the corners.
A waterproof topper softens the bed and protects it, but it also adds height and heat.
Who it suits
This is the pick when your mattress feels a little too firm and you want protection without stacking two products. It fits adults and teens who like a cushioned surface.
Best for: firm mattresses that need softening, plus spill and sweat protection
Watch for: hot sleepers, and sheets that are too shallow for the added height
Price
Expect to pay in the mid range, roughly $50 to $90 for a queen, with prices shifting by size and thickness.
A topper costs more than a plain protector, so judge it as two purchases in one. If you would otherwise buy a protector and a separate topper, the combined price usually works out well.
3. Casper Waterproof Mattress Protector
How it works
The Casper Waterproof Mattress Protector has a quilted, soft top layer over a waterproof backing, and it is hypoallergenic. It fits mattresses up to 16 inches deep, which covers most standard and many thick beds. Casper suggests washing it cold and air-drying it to avoid shrinkage.
It relies on deep pockets rather than an elastic band to stay in place, so fit matters more than with a strap-style cover. The fabric you feel is the quilted top, not the barrier, and that is why this style is usually quieter than covers with a film-like surface.
If you hate the plasticky feel of most protectors, a quilted top is the fix.
Who it suits
Light sleepers and couples who notice every rustle will like this one. It also suits anyone who wants the protector to feel like part of the bedding.
Best for: quiet, soft protection on standard to fairly thick mattresses
Watch for: mattresses deeper than 16 inches, restless sleepers who may need to re-straighten it, and slower laundry because of air drying
Price
This is a higher-priced pick, usually around $90 to $130 for a queen, depending on size and sales.
That is several times the cost of a budget cover, so it makes sense when comfort and noise are your main complaints. If you only need a barrier, a cheaper option does the same core job.
4. Utopia Bedding Waterproof Mattress Protector
How it works
The Utopia Bedding Waterproof Mattress Protector follows the standard formula: a fitted cover with a waterproof layer under a soft top fabric. It aims at the budget end of the market, where the goal is solid basic protection at a low price.
Budget covers are where crinkle noise and thick, stiff backings show up most. Before you buy, read the recent reviews for mentions of noise, fit and how the cover held up after washing. Also confirm the pocket depth against your mattress, since cheap covers sometimes run shallow.
Spend the savings on a second cover, because rotating two covers beats one expensive one.
Who it suits
This is the pick for tight budgets and beds that see frequent accidents. It works well for a student room, a kids' bed or a spare room.
Best for: budget-conscious households and beds that need frequent washing
Watch for: crinkle noise in reviews, and warmth if you sleep hot
Price
Utopia Bedding is usually the cheapest pick here, often around $20 to $35 for a queen, with some variation by size.
At this price, you can buy two and always have a clean cover ready after an accident. Look at the listing for the size chart and depth before you order.
5. Protect-A-Bed AllerZip waterproof encasement
How it works
The Protect-A-Bed AllerZip is a zippered encasement that wraps all six sides of the mattress. Once you zip it closed, the mattress sits in a sealed cover. The listing positions it around allergen and bed bug protection as well as liquids, which makes it the most thorough option on this list.
Installation takes more effort than a fitted cover. Strip the bed, lift the mattress and zip slowly so the teeth do not snag the fabric. An encasement is a barrier and not a treatment, so if you already have bed bugs you still need pest control.
A zippered encasement is the only option here that protects the mattress on every side.
Who it suits
Choose this if you want maximum protection, have allergies, or are buying a mattress you plan to keep for a decade. It also helps when accidents are frequent, since liquid cannot sneak around the edges.
Best for: allergy-prone sleepers and heavy-duty, all-sides protection
Watch for: the mattress height range in the listing, the effort of installation, and care when zipping
Price
This is a higher-priced pick, starting at roughly $100 for a queen and often more for deeper mattresses.
The cost is higher than a fitted cover, but you are buying a full seal. Match the size and depth option to your mattress exactly, because a loose encasement bunches and a tight one strains the zipper.
How to choose a waterproof mattress topper or protector
Choose by mattress depth first, waterproof layer second and your use case third. Most returns come from covers that do not fit or that feel noisy and warm. Get those three factors right and nearly any decent product works.
Match depth, size and fit
Measure your mattress thickness including any topper you already use, and pick a cover whose pocket depth is greater than that number. Say you own a 12-inch mattress and plan to add a 3-inch topper. The total is 15 inches, so a protector that goes over both needs pockets of at least 15 inches. Shop for a 16-inch or deeper listing to leave a margin. If the protector goes under the topper, you only need a pocket a bit deeper than 12 inches.
Also match the exact size, such as Twin XL or California king, because the sizes are not interchangeable. A cover that is too shallow lifts at the corners and leaves edges exposed.
Waterproof layer, noise and heat
Look for a thin polyurethane-type membrane under a cotton or cotton-blend top. Thick vinyl-style backings tend to crinkle and trap the most heat. A soft quilted top, as on the Casper, helps hide the barrier from your skin.
If you sleep hot, choose a thin barrier and a plain fabric top, and avoid cushioned toppers. If chemicals concern you, look for OEKO-TEX Standard 100 on the listing, which certifies textiles against harmful substances. Fully plastic-free covers are usually water-resistant and not waterproof, so decide which matters more to you.
Protecting against urine
For urine, you need a fully waterproof cover, not a water-resistant one. Look for the word "waterproof" and for protection around the whole top surface. For adults, older adults and kids, the most reliable setup is layered:
A fitted waterproof protector on the mattress, or an encasement for heavy use
A washable waterproof bed pad on top, so you strip and wash only the pad after most accidents
A spare protector and spare sheets, so you can remake the bed in minutes
An enzymatic cleaner for any accident that gets through, since it breaks down the odor and not just masks it
Layer a washable pad over the protector, and you turn a midnight disaster into a two-minute sheet change.
Quick comparison of the five picks
Pick | Type | Best for | Price tier |
|---|---|---|---|
SafeRest | Fitted protector | All-around use | Budget to mid |
Bedsure | Waterproof pillow top topper | Softening a firm bed | Mid |
Casper | Quilted protector | Quiet, soft feel | Higher |
Utopia Bedding | Fitted protector | Tight budgets | Budget |
Protect-A-Bed AllerZip | Zippered encasement | Allergies, full seal | Higher |
How to test, wash and replace your cover
Even the best waterproof mattress topper or protector only works if the waterproof layer is intact, so test it when it arrives and check it again now and then. Wash it gently, and replace it as soon as it fails the water test. Most failures come from heat and harsh detergent, not from age.
Test the barrier before you trust it
Run a simple water test with a cup of water and a paper towel:
Put the cover on a flat surface or on the bed.
Pour a cup of water onto the center and let it sit for several minutes.
Slide a paper towel under the spot and press it against the underside.
Check the seams and the corners the same way.
If the towel stays dry, the barrier works. A damp towel means a defect, and you should return the cover.
Wash without wrecking the waterproof layer
Always follow the care label, because instructions differ by brand. Casper, for example, suggests cold water and air-drying. In general, use a gentle cycle, low heat and mild detergent, and avoid bleach and fabric softener, which can break down the waterproof layer.
After an accident, blot the liquid, apply an enzymatic cleaner if anything reached the mattress, and let the mattress dry fully before you remake the bed. A damp mattress invites mildew, so air it out longer than you think you need to.
When to replace it
Replace the cover when the waterproof layer peels or cracks, when seams leak, or when it fails your water test. A louder crinkle than when new is another sign the film is wearing out. Rotating two covers spreads the wear and makes this last longer.
Choose the layer, then protect the bed
A waterproof mattress topper is really a decision about what you want the layer to do. If you only want protection, pick a protector: SafeRest for all-around use, Utopia Bedding on a tight budget, Casper for quiet comfort. Choose the Bedsure pillow top if you want cushioning too, and the Protect-A-Bed encasement if you want every side sealed. Match the pocket depth to your mattress, run the water test, and keep a spare on hand.
