Best Full Mattress Cover With Zipper: 5 Top Picks Compared

Keeping a mattress clean, dry, and free of dust mites and bed bugs is easier when the mattress is fully enclosed. A full mattress cover with a zipper wraps all the way around the mattress, so spills, sweat, allergens, and pests have no open edge to get through. The challenge is finding one that fits your mattress depth, feels comfortable under your sheets, and actually seals the way its marketing suggests. This guide compares five popular full-size zippered encasements so you can narrow your choices quickly. Each pick is described by its design, fit, materials, and care needs, along with the trade-offs you should weigh before you buy.

Utopia Bedding Full Size Zippered Mattress Protector for All-Around Coverage

This Utopia Bedding encasement is designed for a full mattress measuring 54 by 75 inches, with a listed depth fit of up to 13 inches. It uses a smooth, knitted polyester face and a wrap-around zipper that closes the mattress on all sides. The product is marketed as 100% waterproof and as a barrier against bed bugs and dust mites, which makes it a practical choice for people who want complete enclosure rather than a simple top-only pad.

The stretchy fabric is one of the more useful features here. A tight stretch fabric can make the cover easier to slip on and less likely to bunch up overnight, which is a common annoyance with thinner protectors. The listed care instructions are straightforward: machine wash and tumble dry on low heat with your regular laundry. That matters because a mattress encasement that needs special handling tends to get skipped, and a cover that gets skipped stops doing its job.

Many owners appreciate that the fabric stays quiet and lies flat, so you do not hear crinkling each time you shift position. In everyday use, the zipper is the critical point. A wrap-around closure gives you the most complete seal, but it also needs careful alignment when you first pull it on. Take your time during setup, and you will get a much cleaner fit. Compared with the other picks on this list, this model stands out for its balance of stretch, quiet fabric, and broad depth range. It is a solid default choice for households that want a soft, general-purpose encasement.

Pros:

• Stretchy knitted fabric that fits a wide range of mattress depths
• Quiet, smooth surface that lies flat under sheets
• Simple machine-wash care with low-heat drying
• Marketed as waterproof and as a bed bug and dust mite barrier

Cons:

• Zipper alignment can take patience during the first installation

Verdict: This is a strong all-around choice for most full-size beds with standard to moderately deep mattresses. If you want a soft, quiet, fully enclosed cover that is easy to wash, it deserves a spot on your shortlist.

Guardmax Jersey Knit Encasement With a Six-Sided Seal

The Guardmax encasement is built for a full mattress measuring 54 by 75 inches. Its listed depth is 12 inches, with stretch up to 13 inches, so it sits in the same range as the Utopia option above. The defining feature is the zipper design. The nylon closure runs around three sides and tucks under a stitched guard flap, which is meant to remove the small open gap that can exist at the zipper pull on other models.

The jersey knit face feels closer to a soft cotton T-shirt than to the plastic-like texture many buyers expect from a waterproof cover. That makes a real difference for people who run warm or who simply dislike the noise of a crinkly protector. The fabric is also described as breathable and able to handle warm washes, and the product lists OEKO-TEX Standard 100 certification, which is a useful detail for shoppers who prefer a fabric with an independent safety standard behind it.

In practical use, the sealed design is what most people buy this cover for. A flap over the zipper is a thoughtful touch that reduces the chance of a gap appearing over time. The trade-off is that the cover is less forgiving of rushed installation. Because you must slip it over the mattress like a pillowcase, a mattress that is much deeper than the listed range will feel stretched. Measure before you buy. Among the five picks, Guardmax is the best fit for someone who values a soft, sheet-like feel and a carefully sealed closure.

Pros:

• Six-sided design with a zipper that is backed by a guard flap
• Soft jersey knit surface that feels comfortable against bare skin
• Listed OEKO-TEX Standard 100 certification for the fabric
• Breathable face that works well for warmer sleepers

Cons:

• The listed depth range is narrower than some deeper options, so a thick mattress may feel tight

Verdict: Guardmax is a good pick for standard full-size mattresses where a soft, quiet surface and a carefully finished zipper matter most. If your mattress is within the listed depth range, it is a dependable, comfortable choice.

SureGuard Deep-Fit Encasement for Thicker Mattresses

SureGuard is the deepest option in this group, designed for full mattresses between 13 and 16 inches thick. If your mattress is taller than the standard range, this is the model that is most likely to fit without strain. It is a six-sided encasement, which means it covers the top, bottom, and all four sides, and it is marketed as 100% waterproof with a bed bug proof zipper.

The top layer is a 100% cotton terry fabric. Terry is absorbent and tends to feel softer and more natural than polyester, and the product description notes that it wicks moisture while still keeping the feel of your mattress. Many owners appreciate that the cover does not feel plasticky under sheets. The listed materials are also free from vinyl, PVC, and phthalates, and the product carries GREENGUARD Gold certification, which is a good signal for people who are sensitive to certain chemical odors or who want a cleaner indoor environment.

The main consideration with this design is the level of care it requires. The product description suggests that for frequent accidents, you should place a fitted mattress protector over the encasement, which is a sensible approach for households with young children or pets. It also recommends pairing the encasement with a matching box spring cover for bed bug protection. The product carries a 10-year quality guarantee, which adds some confidence for a longer-term purchase. Compared with the other picks, SureGuard trades a little flexibility for depth, durability, and a more natural-feeling surface.

Pros:

• Designed for thicker mattresses in the 13 to 16 inch range
• Absorbent cotton terry top that feels natural under sheets
• Listed GREENGUARD Gold certification and free of vinyl, PVC, and phthalates
• Backed by a stated 10-year quality guarantee

Cons:

• Works best when paired with a separate fitted protector and a box spring cover, which adds to the total setup cost

Verdict: SureGuard is the right choice for buyers with a thick mattress or a serious concern about bed bugs and waterproof protection. If your mattress is deeper than the other covers accommodate, this is the most practical option on this list.

CrystalTowels Six-Sided Encasement With a TPU Waterproof Layer

The CrystalTowels encasement is a six-sided zippered cover for full mattresses measuring 54 by 75 inches. It is listed for mattresses up to 16 inches deep, which makes it another good option for thicker beds. The product uses a TPU backing layer as its waterproof barrier, paired with a soft polyester surface. TPU is a flexible polymer that is commonly used in waterproof layers, and it is the main reason this product is positioned as a spill and moisture barrier.

The fabric is described as breathable and quiet, which suits sleepers who want a cover that does not rustle when they move. Polyester is durable and dries quickly, so it is a practical choice for regular washing. The stretchable fabric and reinforced zipper are meant to create a snug fit, although the listed depth range means you should still check your mattress height before ordering. A cover that stretches across a mattress that is too thick can put strain on the seams over time.

In everyday use, this model suits households that need waterproof protection first and bed bug barrier second. Its care instructions are simple, and it can go through a regular wash and low-heat dryer cycle. Some buyers note that the surface feels more like a standard bedding fabric than a dense knit, which can be a plus for people who prefer a lighter, airy feel. Compared with the other options, CrystalTowels is a sensible middle ground between depth range and everyday practicality.

Pros:

• Six-sided full coverage with a zipper closure
• TPU waterproof backing that helps guard against spills and sweat
• Breathable polyester surface that stays quiet under sheets
• Listed for mattresses up to 16 inches deep

Cons:

• The product listing does not highlight a specific bed bug certification, so buyers focused on pest control should compare its sealing details closely with the other options

Verdict: CrystalTowels is a practical, waterproof-focused encasement for deeper full-size mattresses. If waterproof protection and a breathable surface are your priorities, it is a good option, especially if you want a simpler pest-proofing approach.

Utopia Bedding Premium Six-Sided Encasement With a Deep Pocket Fit

This second Utopia Bedding model is built for full mattresses measuring 54 by 75 inches and is described with a 6-inch deep pocket. That depth specification is the most important detail to check before buying. A 6-inch pocket is much shallower than the 13-inch fit of the first Utopia cover, so it is best suited to standard-depth mattresses. If your mattress is thick, this model may not seal properly, and you should choose one of the deeper options instead.

The fabric is a smooth knitted material that the listing describes as breathable, since it does not trap heat the way some plastic-backed covers can. The zippered closure is designed to keep out bed bugs and dust mites, and the product is also described as waterproof, which gives it dual protection against spills and stains. The knit surface tends to feel soft and quiet, which is important for people who want a cover that disappears under their sheets.

Care is simple. The product is designed to go into a regular washing machine, which keeps maintenance manageable for busy households. In practical use, the main question is fit. A snug encasement on a mattress that matches its depth will feel secure, but a mismatch can leave the cover loose or strained. Compared with the first Utopia pick, this model is less flexible about depth but gives you a similar fabric feel and waterproof protection. It is a good match for standard mattresses where the measurements line up.

Pros:

• Smooth, breathable knitted fabric that does not trap much heat
• Zippered six-sided design for bed bug and dust mite protection
• Waterproof layer that helps guard against spills and stains
• Simple machine-wash care

Cons:

• The listed 6-inch deep pocket is shallow, so it may not fit thicker mattresses properly

Verdict: This is a good choice for standard-depth full mattresses where you have confirmed the measurements. If your mattress is thicker than about 6 inches, skip this model and choose a deeper option from this list.

How to Choose the Right Full Mattress Cover With a Zipper

Measure Your Mattress Depth First

Depth is the single most important factor when buying a zippered encasement. Measure the height of your mattress from the bottom edge to the top, with the mattress bare and without a topper. Many listings give a maximum depth, and a cover that is too shallow will strain at the seams, while one that is far too deep may sag or fail to seal. Choose a product whose listed range includes your measurement, and leave a little room if your mattress is close to the upper limit. The five picks in this guide range from shallow pocket designs to models that fit mattresses up to 16 inches thick, so measuring first will narrow your options quickly.

Understand the Difference Between Waterproof and Water-Resistant

Not every cover marketed for spills offers the same level of protection. A waterproof layer, such as a TPU backing or a sealed membrane, blocks liquids from soaking through to the mattress. A water-resistant fabric may slow down a spill but will not necessarily stop it. Read the product description carefully, and pay attention to phrases that describe a waterproof layer beneath the surface. If you have children, pets, or a history of night sweats, a true waterproof barrier is worth prioritizing over a softer, less protective fabric.

Look at the Zipper and Seal Design

The zipper is where most encasements succeed or fail. A six-sided design that closes around the mattress is more complete than a top-only protector, but the quality of the zipper still matters. Look for descriptions of guard flaps, stitched closures, or specialized zipper technology, since these details reduce the chance of gaps forming over time. Keep in mind that a zipper will need to be opened and closed regularly for washing and inspection, so a smooth, sturdy closure is more valuable than a flashy one. If bed bug protection is a concern, the zipper and seams deserve close attention.

Consider Fabric Feel and Breathability

Because the encasement sits directly under your sheets, the fabric affects comfort every night. Knitted polyester and jersey knit fabrics tend to feel soft and quiet, while cotton terry offers an absorbent, natural surface. Some waterproof layers can trap heat, so if you tend to sleep warm, look for a breathable face fabric and read how the product describes airflow. The best choice depends on whether you prioritize a sheet-like feel, absorbency, or the quietest possible movement under the covers.

Plan for Washing and Long-Term Care

A mattress encasement only works when it stays clean and intact, so choose a product you can realistically wash. Most of the covers in this guide are listed as machine washable with low-heat drying, which is important because high heat can weaken waterproof layers and shrink fabric. Keep the cover on a regular laundry schedule, and inspect the zipper and seams periodically. If you deal with frequent accidents, consider adding a fitted mattress protector on top, which is a common and practical approach for households with young children or pets.

Think About Certifications and Materials

Some encasements list third-party certifications, such as OEKO-TEX Standard 100 for textiles or GREENGUARD Gold for low chemical emissions. These details can help you compare products beyond the basic specifications. If you are sensitive to certain materials or prefer cleaner indoor air, read the material list carefully and check whether the product is free from vinyl, PVC, or phthalates. Certifications do not replace performance, but they can help you choose between two products that otherwise look similar on paper.

Frequently Asked Questions

Do zippered mattress covers stop bed bugs completely?

A zippered encasement can make it much harder for bed bugs to reach the mattress, since the cover fully encloses it when the zipper is closed. However, no product guarantees complete pest control on its own. Bed bugs can still hide in the bed frame, headboard, and surrounding furniture. For the best results, pair an encasement with regular inspection and cleaning, and follow any professional guidance if you have an active infestation.

Can I use a waterproof encasement with a mattress topper?

Yes, but check the depth carefully. A topper adds height, so the total thickness of your mattress and topper must fit within the cover’s listed range. If the combined height is too much, the zipper may strain or fail to close properly. Measure the full stack before choosing a product, and consider a deeper model if you use a thick topper.

How often should I wash a mattress encasement?

Most households wash a mattress encasement every one to three months, and more often if there has been a spill, illness, or pet accident. Follow the care label, which typically recommends machine washing and low-heat drying. Regular washing helps keep dust, allergens, and moisture from building up on the surface.

Will a zippered encasement make my bed hot or noisy?

It can, depending on the material. Waterproof layers may reduce airflow, which some sleepers notice on warm nights. Knitted and jersey fabrics tend to be quieter than plastic-like covers, while cotton terry feels more natural. If heat is a concern, look for a breathable face fabric and consider using breathable sheets on top.

Do I need a box spring cover as well?

A box spring cover is not required for every bed, but it is recommended if bed bug protection is your main goal. Enclosing only the mattress leaves the box spring exposed, and pests can move between the two. Some manufacturers offer matching box spring encasements designed to work with their mattress covers.

Is a deeper mattress cover always better?

Not always. A cover that is much deeper than your mattress can sag, wrinkle, or fail to seal tightly. The best choice is a product whose depth range closely matches your mattress height. Choose the deepest option only if your mattress actually requires it.

Are these covers suitable for children’s beds?

Many parents use waterproof encasements on children’s beds because they protect against spills and accidents. Choose a cover with a soft, quiet surface and a secure zipper so it does not disturb sleep. Keep in mind that a waterproof layer alone does not solve every issue, so pairing the encasement with a fitted protector can make cleanup easier.

Final Recommendation

For most full-size beds with standard-depth mattresses, the Utopia Bedding zippered protector is the most balanced choice. Its stretchy knitted fabric, wrap-around zipper, and listed waterproof and bed bug barrier features make it a practical, comfortable option for everyday use. If you want a softer, sheet-like feel and a carefully sealed closure, the Guardmax encasement is a strong alternative. Buyers with thicker mattresses should look at the SureGuard or CrystalTowels models, since both list deeper fits, with SureGuard offering the most natural-feeling cotton surface and additional certifications. The Utopia six-sided model with a 6-inch pocket suits standard mattresses only when your measurements confirm the fit. Measure your mattress first, decide whether waterproof protection or pest control matters more to you, and choose the model whose depth range and features match those needs.
