Best Mattress Protector: Eight Covers Sorted by Size and Depth
As an Amazon Associate we earn from qualifying purchases.
The best mattress protector is the one that matches your bed size and mattress depth, blocks the liquids you actually worry about, and stays quiet and comfortable through a full night. This guide covers eight protectors and encasements, from twin and full covers to queen, king and a split California king set. Each section is based on its own title, brand, bullet points and specifications. Several of these products look alike on the page, so the sections point out the exact differences the data shows and nothing beyond that.
Quick answer
- For a queen bed with a cotton terry top and a stated waterproof layer, the SureGuard fitted protector is the most direct match in this group.
- For a bamboo look and feel, the PlushDeluxe covers come in king, queen and full sizes, all listed with a waterproof bamboo viscose top.
- For a twin bed or a daybed, the Purple Twin and Artivestion covers are the twin options, and their depth ranges differ.
- For an adjustable base or a split king, the Four Seasons Essentials encasement is the only full six sided cover in this group.
Measure the mattress before you compare covers
Size and depth decide most of the fit, so start with a tape measure. The listings in this group give exact sizes such as 60 by 80 inches for queen, 76 by 80 inches for king in the PlushDeluxe listing, 54 by 75 inches for full and 39 by 75 inches for twin in the Artivestion listing. A cover that is only a few inches short will pull off the corners, and one that is too large will bunch under you during the night.
Depth is the number people forget. The listings give depth ranges such as 6 to 20 inches for the SureGuard protector, up to 18 inches for the PlushDeluxe covers, 6 to 18 inches for the SheRest protector and 14 to 18 inches for the Artivestion cover. The Purple Twin is listed at 13 inches deep, and the Four Seasons encasement fits split king or box spring mattresses from 11 to 16 inches deep. If your mattress is deeper than the range, the cover will not fit snugly and the waterproof layer may not reach the edges.
Waterproof layer, fabric and noise
Most protectors in this group use a waterproof layer under a soft top, and the layer is what stops liquids from reaching the mattress. The SheRest listing describes a TPU backing, while the Four Seasons encasement describes a polyurethane inner lining. The Artivestion listing describes a TPU waterproof layer under a terry style top, which is a common combination for a soft surface that still blocks liquids.
Noise matters because a crinkling cover can wake a light sleeper. The PlushDeluxe, Purple and SureGuard listings all state that they are silent or free of crinkle, and the Purple listing describes a stretchy fabric that lets your body sink in. Look for those words in the bullets if a quiet night matters to you, and remember that the claim is only as good as the fabric you choose.

Choosing by bed type and use
For a standard bed with no special needs, a fitted sheet style cover is the simplest choice, since it goes on like a sheet and stays on through the night. The SureGuard queen and the PlushDeluxe covers both use this design, so choose between them on size and fabric. The SureGuard top is cotton terry with a stated thread count of 500, while the PlushDeluxe covers use bamboo viscose, and the king listing states a thread count of 260.
For a child’s bed or a daybed, the Purple and Artivestion twin covers fit that use. The Artivestion listing describes its cover for a daybed and a guest room, and it names a 14 to 18 inch depth. The Purple listing is built around a five sided design with a zipper, which suits a mattress that needs protection from kids, pets and food, though its specifications list the material as plastic.
For a bed that sits on an adjustable base, or for a split king setup, the Four Seasons encasement is the only option here that covers the mattress on all six sides. Its listing warns that it is not compatible with Sleep Number or Smart Beds, so check your bed brand before buying.
If one bed has frequent accidents, count the covers you need before you order. A single protector leaves the mattress exposed while it is in the wash, so many buyers keep two covers of the same size and rotate them. The SureGuard bullets make the same suggestion, so a second cover in the same size and depth range is the practical match. Rotating covers also gives the wet one time to dry fully before it goes back on the bed.
The eight covers in detail
SureGuard Waterproof Mattress Protector Queen
SureGuard sells this white queen mattress protector with a cotton terry top and a waterproof layer underneath. Its bullet points describe protection against perspiration, bed wetting, liquids and stains, a fitted sheet design with a stretchable skirt, and a cover that blocks dust, dirt and dander on the top side. The specifications list a thread count of 500, a weight of 2.1 pounds and a machine wash and dry care line. Choose it if you want a queen fitted protector with a soft cotton top, and you plan to keep a second one on hand for frequent accidents, since the bullets suggest that approach.
PlushDeluxe Bamboo Waterproof Mattress Protector King
PlushDeluxe makes this white king cover from bamboo viscose, measured at 76 by 80 inches and listed to fit mattresses up to 18 inches deep. The bullets describe a waterproof membrane that resists spills and bodily fluids, and they say the surface is silent with no crinkling. The specifications list 60 percent bamboo with a 30 percent polyester bottom layer, a thread count of 260 and a hypoallergenic, breathable finish. Choose it if you have a king bed and want a bamboo surface that the listing describes as cool and fresh.
SheRest Waterproof Mattress Protector Queen
SheRest sells this gray queen protector with a TPU backing and a 100 percent polyester top, and the bullets describe a spill proof and oil and stain resistant barrier. The listing says the 360 degree elastic skirt fits mattresses from 6 to 18 inches deep, and its specifications add a deep pocket and a pull on closure. The care line calls for cold water machine washing and low tumble drying, which the bullets say keeps the waterproof performance intact. Choose it if you want a queen protector with a deep pocket range that starts lower than most, and you are fine with a polyester top.
PlushDeluxe Bamboo Waterproof Mattress Protector Queen
This is the queen size version of the PlushDeluxe bamboo cover, listed at 60 by 80 inches and fitting mattresses up to 18 inches deep. Its bullets and specifications match the king version in fabric, care and waterproof claim, including the bamboo viscose top and the machine wash care line. The listing describes it as suitable for incontinence care, potty training and pets, and it says the bamboo fabric wicks moisture away from the sleeper. Choose it if you want the bamboo cover in a queen size and do not need the extra width of a king.
PlushDeluxe Bamboo Waterproof Mattress Protector Full
This is the full size version of the same PlushDeluxe bamboo cover, measured at 54 by 75 inches with the same up to 18 inch depth. Its bullets describe the same bamboo viscose surface, the silent waterproof layer and the fitted sheet style closure. Because the fabric and claims match the queen and king versions, the main difference you can rely on is the size. Choose it for a full bed or a smaller guest room bed where the 54 by 75 inch footprint fits.
Purple Mattress Protector Twin 13 Inch Deep
Purple makes this white twin protector with a 13 inch depth and a five sided design that its title describes as stain resistant and machine washable. The bullets describe a stretchy fabric that lets your hips and shoulders sink in and a surface that does not crinkle like plastic. The specifications list a zipper closure, a weight of 2.2 pounds and a water resistant rating rather than a full waterproof rating, so read the title claim about stains with that in mind. Choose it if you want a zippered twin cover that protects against kids, pets and food, and you value a stretchy, quiet feel.
Artivestion Waterproof Twin Mattress Protector
Artivestion sells this white twin protector in a 39 by 75 inch size, built for a daybed or a guest room bed. The bullets describe a leak proof TPU backing with a soft plush terry top, a stretch deep pocket that fits mattresses from 14 to 18 inches, and a 360 degree elastic band for a secure fit. The specifications list polyester, a pull on closure and a machine wash care line. Choose it if you have a daybed or a twin mattress in that depth range and you want a fitted cover that goes on and comes off with little effort.
Four Seasons Essentials Split Cali King Mattress Encasement
Four Seasons Essentials sells this white split California king encasement as two pieces, each listed at 36 by 84 inches. Its title and bullets describe a waterproof zippered cover with a polyurethane lining, a polyester surface and a six sided stretch fabric that wraps the whole mattress. The bullets also say it is built for mattresses from 11 to 16 inches deep, is hypoallergenic and is machine washable. Choose it if you have a split king or an adjustable base and want the full six sided coverage, after you confirm the bed brand is not one the listing excludes.
Mistakes that cause leaks, noise and poor fit
The most common mistake is buying by size alone. Two covers can both be queen size and still fit differently, because one covers 6 to 20 inches of depth and another tops out at 18 inches. Check the depth range against your mattress before you order.
The second mistake is ignoring the claim wording. A protector described as water resistant, like the Purple cover in its specifications, handles spills differently from one described as waterproof. Read the exact term in the specifications and the bullets.
Third, buyers forget the wash routine. The SureGuard listing suggests keeping two covers for frequent accidents, and the SheRest listing calls for cold water and low tumble drying. Plan your wash days so you always have a clean cover on the bed.
Finally, do not assume that a silent claim means silent in every fabric. The quietest options in this group are the ones whose bullets describe a soft top over a flexible waterproof layer, so read the top fabric line before you commit.
Questions people ask about mattress protectors
Is a waterproof mattress protector the same as a mattress encasement?
A protector covers the top and sides with a fitted skirt, while the Four Seasons encasement wraps all six sides of the mattress with a zippered closure.
Can I use a mattress protector on an adjustable bed?
The Four Seasons encasement is listed for adjustable beds, but its listing excludes Sleep Number and Smart Beds, so confirm your bed model first.
How often should I wash a mattress protector?
The listings give machine wash care lines for each cover, and the SureGuard listing suggests keeping a second cover on hand so one can be washed while the other protects the mattress.
Do bamboo protectors stay cooler than polyester ones?
The PlushDeluxe bullets say the bamboo fabric wicks moisture and regulates heat, but the listings do not give a measured temperature difference, so treat that as a stated feature rather than a proven result.
What depth range should I look for?
Pick a cover whose listed depth range covers your mattress height with a little room, since the listings here range from 6 to 20 inches for the widest fit and from 11 to 16 inches for the split encasement.
Bottom line
Choose the cover whose size and depth range match your mattress first, then pick the top fabric and waterproof wording that suit your sleep. For most standard beds, a fitted waterproof cover with a soft top is the right choice, and the Four Seasons encasement is the one to choose only for a split king or an adjustable base.
