Best Mattress Cover Buying Guide

Material and Comfort

The fabric of a mattress cover directly affects how it feels against your skin and how well it regulates temperature. Common materials include cotton, polyester, bamboo-derived rayon, and Tencel.

Cotton covers are breathable and soft, while bamboo and Tencel offer natural moisture-wicking properties and a silky feel. For those who prefer a plush surface, quilted mattress pads add a layer of cushioning.

When choosing, consider your personal comfort preferences and whether you tend to sleep hot. A cover with a high thread count or a smooth finish can also reduce noise and improve overall sleep quality.

Many modern covers combine multiple materials to balance protection and comfort. For example, a polyester back layer provides waterproofing while a cotton top layer maintains breathability.

Some covers also feature a noiseless design, which is important if you move around during the night.

If you share a bed, a cover that minimizes motion transfer and feels like a natural part of the mattress can make a big difference. For more on choosing the right sleep surface, see our best mattress guide.

Waterproofing and Protection

Waterproofing is a key feature for many buyers, especially those with young children, pets, or a tendency to spill drinks in bed. Most waterproof mattress covers use a polyurethane (PU) or vinyl membrane laminated to a fabric layer.

Higher-quality covers use a breathable membrane that allows air to pass through while blocking liquids. Look for covers that are 100% waterproof rather than water-resistant, and check whether the waterproof layer is bonded to the fabric or simply a separate sheet.

A bonded construction is more durable and less likely to peel over time.

Beyond waterproofing, consider protection against allergens, dust mites, and bed bugs. Encasements that zip around the entire mattress offer the most comprehensive protection, while fitted sheet-style covers are easier to install but leave the bottom exposed.

If you have allergies, a cover with a pore size small enough to block allergens is essential. For more details, read our waterproof mattress cover guide.

Fit and Depth

A mattress cover must fit snugly to stay in place and provide even protection. Most covers are designed for mattresses with a specific depth range, typically between 8 and 18 inches.

If your mattress is thicker than average, look for a cover with deep pockets or an adjustable elastic skirt.

Some covers come with a zippered encasement that fully encloses the mattress, which is ideal for preventing bed bugs and dust mites. Before purchasing, measure your mattress height and compare it to the cover’s specifications.

A poorly fitting cover can bunch up, shift, or leave parts of the mattress exposed.

Many brands now offer covers with stretchy side panels or a fitted sheet design that accommodates a range of depths. For example, some covers fit mattresses from 8 to 21 inches, making them versatile for different bed sizes and topper combinations.

If you use a mattress topper, you may need a cover that can fit over both the mattress and the topper. Check the product details carefully to ensure compatibility.

Breathability and Cooling

One common concern with waterproof mattress covers is heat retention. Early designs often trapped body heat, leading to uncomfortable, sweaty nights.

Fortunately, modern covers use advanced materials such as 3D air mesh, phase-change materials, or moisture-wicking fabrics to enhance airflow and dissipate heat. Look for covers labeled as breathable, cooling, or with a high air permeability rating.

Bamboo and Tencel covers are naturally cooler, while some covers feature a quilted surface that promotes air circulation.

If you sleep hot, prioritize a cover with a cooling technology that actively regulates temperature. Some covers have a smooth, cool-to-the-touch surface, while others use a waffle or honeycomb weave to increase airflow.

Reading verified buyer feedback can give you real-world insight into how well a cover performs in terms of temperature regulation. For more on staying cool at night, check out our best mattress cover for comfort guide.

Ease of Cleaning

Mattress covers need regular washing to maintain hygiene and performance. Most covers are machine washable, but it is important to check the care instructions.

Some covers can be washed in warm water and tumble dried on low, while others may require gentle cycles or air drying.

Covers with a zippered encasement may be bulkier to wash, but they offer the advantage of protecting the entire mattress. Look for covers that are stain-resistant and quick-drying to make maintenance easier.

For households with allergies or asthma, washing the cover frequently is essential. A cover that retains its shape and waterproof integrity after multiple washes is a better long-term investment.

Many top-rated covers are designed to withstand dozens of wash cycles without peeling or losing effectiveness. If you have a busy schedule, consider a cover that is wrinkle-resistant and easy to put back on after washing.

Frequently Asked Questions

What is the difference between a mattress cover and a mattress protector?

A mattress cover is a general term that includes both protectors and pads. A mattress protector is typically a fitted sheet-style cover that guards against spills, allergens, and dust mites.

A mattress pad or topper adds extra cushioning and may or may not be waterproof. Encasements zip around the entire mattress for full protection. When shopping for the best mattress cover, consider what level of protection and comfort you need.

Can a mattress cover help with back pain?

A mattress cover alone is unlikely to alleviate back pain, but a thick mattress topper can add pressure relief and support. If you have back pain, consider a topper made of memory foam or latex.

For more on supportive sleep surfaces, see our best firm foam mattress guide.

How often should I wash my mattress cover?

It is recommended to wash your mattress cover every one to two months, or more frequently if you have allergies, pets, or spills. Always follow the care label instructions to maintain waterproofing and fabric integrity.

Regular washing helps prevent the buildup of dust mites, sweat, and odors.

Will a waterproof mattress cover make me sweat?

Older waterproof covers often trapped heat, but many modern designs use breathable membranes that allow air to circulate while blocking liquids. Look for covers labeled as breathable, cooling, or made from bamboo or Tencel.

Reading reviews from verified buyers can help you find a cover that stays cool.

Do I need a zippered encasement or a fitted sheet-style cover?

A zippered encasement provides full protection against bed bugs, dust mites, and spills because it covers the entire mattress. A fitted sheet-style cover is easier to put on and remove but leaves the bottom and sides exposed.

Choose an encasement if you want maximum protection, especially for allergy or bed bug concerns. For more on bed bug prevention, check our best mattress cover for comfort guide.

Can I use a mattress cover with an adjustable bed?

Yes, many mattress covers are compatible with adjustable beds, but you should look for a cover with a flexible, stretchy design that moves with the bed.

Avoid covers that are too stiff or have a rigid waterproof layer that could crack. Check the product specifications to ensure it is suitable for adjustable bases. For more on adjustable beds, see our adjustable bed bases category page.
