The Malouf Sleep Tite Encase LT Mattress Protector is made from lightweight, durable polyester. Beneath the polyester top layer is a waterproof H2Pro polyurethane membrane. This waterproof technology is particularly effective in preventing moisture from seeping into the mattress or accumulating on the sleep surface. It encourages airflow throughout the mattress and helps prevent heat buildup, while ensuring a second line of protection against liquid, allergens, bed bugs, dust mites, and mold. Despite the waterproof membrane, the Malouf Sleep Tite makes minimal noise when sleepers move around on the mattress.

The Malouf protector’s patented deep pocket design and full-length elastic allow it to fit most mattresses between 6 and 14 inches deep. The protector has a three-sided MicroTite liquid-proof zipper that helps it slip on and off the mattress.

Once removed, it can be hand or machine washed and line dried. Purchasers can also tumble dry the protector on low with other bedding. However, it is important to note that tumble drying the protector alone or drying it in heat over 125 degrees may damage the fibers in the protective membrane, which may reduce its durability, effectiveness, and lifespan.

Malouf offers a 15-year limited warranty that covers defects in materials or workmanship, as long as the claim is made within five days of noting the damage, and all laundering and care instructions are followed. The warranty also protects against mattress stains caused by material or workmanship defects.

What is a Mattress Encasement?

A mattress encasement is a six-sided barrier that completely covers every part of your mattress. The purpose of a mattress encasement is to protect your mattress from contaminants, including moisture, mildew, mold, pet dander, and dust mites.

The difference between a mattress encasement and a mattress protector, which performs a similar function, is that a mattress encasement covers the entire mattress, including the underside. This provides full coverage against contaminants. A mattress protector, which may also be called a mattress cover, is usually five-sided and is applied to the bed like a fitted sheet. Its main purpose is to protect the mattress surface from spills or stains.

It is important to note that mattress protectors and mattress encasements differ from mattress pads and mattress toppers. Mattress pads and mattress toppers are primarily added to adjust the comfort or firmness of the mattress, rather than to protect against contaminants.

How to Choose a Mattress Encasement

Once you have decided that a mattress encasement is right for you, there are several factors to consider before making a purchase. Though mattress encasements serve the same primary purpose, they differ when it comes to fit, price, waterproofing, and other characteristics. We’ll highlight these differences to help you choose a mattress encasement that suits your needs.

What to Consider When Purchasing a Mattress Encasement

Focusing on the following factors when shopping for a mattress encasement will help you narrow down your search. Mattress companies have a tendency to use buzzwords to market their products, which may not tell you what you need to know before making a purchase.  Knowing what to look for will help ensure that the product you’re considering matches your individual needs, as different encasements may be better for certain mattresses and situations.

Whether you are shopping online or at a brick-and-mortar location, product information should be readily available. There are several essential qualities to consider, including the fit, waterproofing, noise potential, and quality of materials. We’ll break down these and other important elements to keep in mind when shopping.


One of the main purposes of a mattress encasement is to keep moisture, including spills, sweat, and other liquids, off of the mattress. This can help prevent stains, mold, and mildew.

Many mattress encasements are waterproof or water-resistant. These types of encasements may appeal to shoppers who want to protect their mattresses from sweat, urine, or humidity. Some encasements are designed to wick away moisture or repel water without being fully waterproof.

The type of waterproofing used will determine how effective the encasement is at preventing water damage to the mattress. Waterproof encasements may include polyurethane membranes or liners for more complete protection.


Like all products, mattress encasements come in a range of prices, depending on factors like size and type of material. Encasements with waterproofing or other features may be more expensive than models with simple fabrications.


Most mattress encasements are made with polyester or cotton, which are typically silent. Some waterproofing materials can cause a rustling or crinkling noise, which may be bothersome to sleepers.

When shopping for a mattress encasement in-store, you may be able to feel the fabric prior to purchasing to see if it makes a rustling noise. If you are shopping online, customer reviews often provide insight into any noise the encasement makes when the user is moving around on it.

Quality Materials

The materials used to make a mattress encasement affect its performance and durability. Mattress encasements can be made out of a wide variety of materials. The most popular ones include:

  • Cotton: Cotton is a natural fiber that is soft, breathable, and absorbent. Tighter weave patterns, such as percale, may be more suitable for acting as a barrier to allergens and other contaminants.
  • Polyester: This common synthetic fabric is easy to clean, which helps prevent the buildup of allergens. It is also moisture-wicking and durable. Though it may not be as breathable as cotton, it is less permeable, which can make it more effective as a barrier.
  • Lyocell: Lyocell is a specific type of rayon derived from wood pulp, which is then further treated. It is soft to the touch, moisture-wicking, and sleeps cool, but it may be more expensive than cotton or polyester options.

Ease of Care

To prevent stains or the buildup of allergens, mattress encasements will likely need to be cleaned regularly. A couple of factors will indicate how easy it is to care for a particular mattress encasement, including how easy it is to remove and how easy it is to clean.

Almost all encasements include a zipper closure to make removal and application easier. Some mattresses are quite heavy, which could potentially make an encasement harder to remove. Depending on the encasement and the size of your mattress, it may take two people to remove the encasement for cleaning.

Most washable encasements have relatively simple cleaning instructions. Many of them are machine-washable, and can be tumble dried with low or no heat.

That said, some encasements have specific care requirements to protect the fabric or waterproofing elements. These may include specific temperatures or settings when using the washing machine or dryer.  Following the care instructions from the manufacturer will help keep the encasement from losing effectiveness.

Before purchasing an encasement, look into the specific cleaning instructions and make sure the required care regimen suits your needs.


Most mattress encasements are produced in standard mattress sizes, from twin to California king. Most will also accommodate mattresses with standard profiles, up to 12 inches thick. Shoppers with low- or high-profile mattresses will want to confirm that the pocket depth of the encasement will fit the mattress comfortably.

If you have an adjustable bed, you may also want to consider whether or not the encasement is flexible enough to move along with it. Some encasements are designed with additional stretch to accommodate the different positions of an adjustable bed.

What Are the Benefits of a Mattress Encasement?

There are several benefits of a mattress encasement, as it can be used to protect your mattress from damage and help prevent wear and tear. We’ll highlight the main benefits of this type of bedding to help you decide if a mattress encasement is right for you.

Prevents Damage to the Mattress: One of the main purposes of a mattress encasement is to protect the mattress from things that might damage it, such as moisture, liquids, and dust mites. This helps your mattress maintain its structural integrity, and reduces your exposure to contaminants.

Increases the Lifespan of the Mattress: By preventing damage, an encasement may increase the lifespan of the mattress. A new mattress is often a large investment, and protecting it from wear and tear can prevent needing to replace it prematurely.

Prevents the Buildup of Allergens: Those who suffer from allergies, chemical sensitivities, or mold sensitivities know how essential it is to keep the sleeping area free of irritants and allergens. Exposure to elements that trigger allergies and/or sensitivities can negatively impact sleep quality. Mattress encasements are one of the best lines of defense against allergen and irritant buildup, especially when cleaned and maintained as recommended.

Helps Protect Against Bed Bugs: Mattress encasements are one of the best preventative measures you can take against a bed bug infestation. It makes the mattress less hospitable to bed bugs, making an infestation less likely.

Frequently Asked Questions About Mattress Encasements

How do I install a mattress encasement?

Mattress encasements generally come with specific installation instructions, but most have a zipper to make application easier. Generally, a mattress encasement is installed on a bare mattress that has been stripped of all bedding and additional mattress pads, toppers, or other accessories. You’ll probably have to lift your mattress in order to get the encasement on correctly. Follow the instructions for your specific mattress encasement in order to install it properly.

Where can I buy a mattress encasement?

Mattress encasements are available for sale in most places where mattresses, bedding, and bedroom accessories are sold, in-store and online. Some mattress companies offer bundle discounts for purchasing a mattress and mattress encasement together. Since sizing is generally standardized, you do not have to purchase an encasement from the same company that manufactured your mattress.

Can I use a mattress encasement on a box spring?

A box spring encasement is a different product than a mattress encasement. The main difference between a mattress encasement and a box spring encasement is that box spring encasements tend to accommodate lower profiles, usually 6 to 9 inches thick. Mattress encasements tend to be larger to fit mattresses ranging from 6 to 18 inches thick.

Additionally, box spring encasements are usually made from rougher, less finished materials, though they are often similarly waterproofed and treated.

It is recommended that you use an encasement for your box spring in addition to an encasement for your mattress, particularly if you suffer from allergies or other sensitivities.

Do mattress encasements protect against bed bugs?

Some mattress encasements protect against bed bugs. These encasements are designed to keep bed bugs from nesting in and infesting mattresses. When it comes to existing infestations, sealing a mattress in a high-quality, low-ventilation encasement is often recommended after a treatment to eliminate any remaining bed bugs and prevent them from escaping.

If bed bugs are a major concern, an encasement provides additional peace of mind and protection against infestation.

How do I clean a mattress encasement?

Most mattress encasements are removable and machine-washable, but take care to follow any guidelines or cleaning instructions provided by the manufacturer.  Washable models should be cleaned regularly to prevent the buildup of allergens and bacteria. Depending on the model, they can usually be machine washed in cold or warm water, and then tumble dried on low, preferably with other bedding. Most mattress encasements can be spot cleaned or vacuumed as needed between washes.

Generally, mattress encasements should not be washed with harsh cleaners, dry cleaned, or ironed. These laundering methods can damage the fibers of the encasement, reducing its effectiveness, durability, and softness. In addition to potentially damaging the product, using these methods will often void the warranty of a mattress encasement.

Rather than assume a mattress encasement is machine-washable, make sure to check the available instructions and follow them as you clean the encasement. Cleaning instructions for specific mattress encasements can usually be found on the bedding tags, packaging, or product website.

How much does a mattress encasement cost?

Mattress encasements typically cost approximately $50 to $100, though there are models available outside of this range. The price of a mattress encasement will often depend on the materials, construction, and brand.

Mattress companies and other retailers may offer promotions or discounts for encasements, including bundled packages when buying a new mattress or other bedding. Seasonal sales and coupons can further discount the retail price.
