Mattress Pad vs. Mattress Protector: Which One Do You Need?

A mattress pad and a mattress protector serve two different purposes: a mattress pad adds comfort, cushioning, and sometimes cooling, while a mattress protector helps guard your mattress against spills, stains, allergens, and everyday wear. Many sleepers use both together for a more comfortable and protected bed.

While a mattress pad and mattress protector seem interchangeable, they’re actually quite different. Although both serve different purposes, they’re both designed to enhance your sleeping experience so you can get the best slumber possible.

Stumped about whether a mattress protector or pad is right for you? Don’t fret. Below, we’ll cover all the bases on mattress pads vs mattress protectors, so you can make the right purchase for your bed.

Key Takeaways

• Mattress pads add extra cushioning and support to a mattress. They’re usually used on older mattresses that have worn down and are an affordable option to make a bed more comfortable. They droop over the sides of a mattress and fit like a fitted sheet.
• Mattress protectors protect a mattress from liquids, body oils, bacteria, fungi, chemicals, and allergens to increase the longevity of your bed and enhance hygiene. They droop over the sides of a mattress like a fitted sheet or fully encase the mattress.
• Mattress toppers are a thick memory foam layer that lies across the top of a mattress and is secured in place by fitted sheets. They are between 2 and 3 inches thick and provide more cushioning than mattress pads.

Mattress Pad vs. Mattress Protector: Quick Comparison

What Is a Mattress Pad?

A mattress pad is a piece of quilted fabric that sits on top of your mattress. Typically, a mattress pad fits like a sheet and is relatively thin—only about 1 inch in thickness. The primary reason for a mattress pad is to increase the comfort of a bed. Newer mattresses usually don’t require one, as they’re not worn down like older mattresses. However, a sleeper may want to add a mattress pad to a newer bed to add another barrier between them and their mattress, or if their mattress is too firm and they want an added layer of comfort.

Benefits of a mattress pad

Mattress pads come with plenty of impressive benefits that can make your sleeping experience a dream come true.

Take a look at how a mattress pad can improve your sleep:

• Increased comfort: The added layer of cushioning can make a firm or worn-down mattress more comfortable. Whether the coils in your innerspring mattress give out or your memory foam mattress begins to break down, a mattress pad can serve as a temporary fix for more cushioning.
• Extends mattress life: Over time, mattresses begin to break down. The weight of our bodies adds pressure to the materials and fabrics, while sweat and bodily fluids can seep through. A mattress pad serves as an extra barrier between you and your mattress. It can absorb light spills, sweat, and fluids and prevent mold and bacteria from growing inside the mattress. Be cautious, though, they don’t offer complete protection like mattress protectors.
• Affordability: Mattress pads are a budget-friendly option to increase the comfort of an older bed. For those who need more time to budget for a new mattress or need a temporary fix, a mattress pad will get the job done.
• Easy to use: Mattress pads are light and easy to place on top of a mattress. They fit like bedsheets, are stable, and are unlikely to move around. They can also be easily removed for washing.

What Is a Mattress Protector?

While a mattress pad adds extra padding, a mattress protector adds extra protection. A mattress protector is a thin piece of protective fabric that covers the top and sides of your mattress, or completely encapsulates it. A mattress protector forms a protective barrier between you and your mattress to prevent spills, bacteria, and some allergens from causing damage.

Mattresses can be an expensive investment, and if you spill liquid or accidentally damage it yourself, sometimes your warranty won’t cover the cost to replace your mattress. And, there are millions of tiny organisms called dust mites inhabiting the average mattress, which can cause you to suffer from allergic reactions.1 To protect your investment and your health, a mattress protector is a wise choice.

At Layla® Sleep, we offer three different mattress protectors, each containing a liquid-proof barrier that’s breathable and sleeps cool. All three protectors are hypoallergenic, stain-resistant, silent, have a dust mite barrier, contain overlocking corners, and most importantly fit great on one of our mattresses in a box.

Benefits of a mattress protector

Mattress protectors are a great way to protect your investment and help you sleep peacefully at night, knowing your mattress will maintain its brand-new feel for longer.

The main benefits of fitting your mattress with a mattress protector include:

• Creates a liquid barrier: A mattress protector creates a liquid barrier to prevent spills, night sweats, body oil, and other bodily fluids from entering your mattress, which can cause mold and unpleasant odors.
• Protects your health: If your allergies get worse at night, you’ll be happy to find that a mattress protector can lessen your symptoms. Mattress protectors prevent allergens, dust mites, fungi, bacteria, and other microorganisms from disturbing you at night. If you sleep with your dog or pet, it’ll also prevent dirt, liquids, germs, and other particles from ruining your mattress.
• Blocks harmful chemicals: Some mattress brands use flame retardants in their mattresses to prevent the spread and growth of fires. However, they’re extremely dangerous to both humans and the environment. Additionally, some mattress brands use plasticizers to make their foam more cushioned, which can lead to asthma and other health problems.² A mattress protector will block these harmful chemicals from causing harm to you while you sleep.
• Protects your warranty: If you spill liquid on your mattress and damage it, your mattress’ warranty most likely won’t cover the damage. A mattress protector will prevent liquids from staining and seeping into your mattress.
• Increases mattress longevity: A mattress protector will prevent moisture from entering your mattress, which breaks down your mattress over time. With a mattress protector, your bed will maintain that brand-new feel for longer.
• Easy to use: A mattress protector can easily be cleaned if you spill liquid or just want to wash it. Some may fit like a fitted sheet, making them easy to put on your mattress.

Mattress Pad vs Mattress Protector: Key Differences

Mattress pads and protectors are two types of covers you can place over your mattress. But what’s the difference between the two? The difference between a mattress pad and a mattress protector is their function. Mattress pads are used to increase the comfort of a bed, while mattress protectors protect your mattress from spills, allergens, and bacteria entering your bed.

Purpose

The biggest difference between a mattress pad and a mattress protector comes down to what they’re designed to do. A mattress pad is meant to make your bed feel more comfortable by adding an extra layer of cushioning, softness, or cooling performance. A mattress protector, on the other hand, is there to shield your mattress from spills, stains, sweat, allergens, and everyday wear, and may also add an additional layer of cooling. Think of a mattress pad as a comfort upgrade and a mattress protector as a layer of defense for your investment.

Comfort and feel

If you’re looking to change how your mattress feels, a mattress pad will have a much bigger impact. Depending on the materials and construction, it can add a plush, quilted feel or help create a cooler sleeping surface. Mattress protectors are designed to be far less noticeable. Most fit snugly over the mattress and add little to no cushioning, allowing you to enjoy the feel of your mattress while keeping it protected underneath.

Protection level

While both products provide some degree of protection, mattress protectors are designed specifically for the job. Most mattress protectors feature waterproof barriers that help prevent liquids from reaching the mattress, while also reducing exposure to dust mites, allergens, and other unwanted buildup. Mattress pads may offer a small buffer against minor spills or daily wear, but they’re not intended to provide the same level of protection as a dedicated mattress protector.

Thickness and construction

Mattress pads are typically made with layers of fabric and filling that create a thicker, more cushioned surface. You’ll often find quilted designs filled with cotton, polyester, or other soft materials. Mattress protectors tend to be much thinner and are designed to sit discreetly beneath your sheets. Some include waterproof membranes or specialized fabrics, but their goal is protection rather than added loft.

Cost

In many cases, mattress protectors are the more affordable option because they use less material and prioritize protection over comfort. Mattress pads often cost more due to their thicker construction, which requires more materials and adds comfort features. While prices vary by brand and the materials used, the right choice depends less on cost and more on your goal: do you want to improve the feel of your bed, protect your mattress, or get the benefits of both?

Mattress Pad vs. Mattress Protector FAQs

Who should choose a mattress protector?

So, do you need a mattress protector? A mattress protector is a smart choice for almost any sleeper, but it’s especially beneficial for households with children, pet owners, allergy sufferers, and anyone who wants to keep their mattress in great condition for years to come. A quality protector helps guard against spills, stains, sweat, dust mites, and everyday wear that can shorten a mattress’s lifespan. If you’ve recently purchased a new mattress, adding a protector is one of the easiest ways to help preserve its cleanliness and overall performance.

Who should choose a mattress pad?

If you answer yes to any of the following questions, you may want to choose a mattress pad:

• Do you need extra support for medical or personal reasons?
• Do you want to adjust the firmness of your mattress and make it firmer or softer?
• Is your mattress old and uncomfortable?
• Do you want to add a light layer of protection between your bedding and mattress?

If you’re consistently waking up at night from being uncomfortable, or are experiencing neck stiffness or body aches, a mattress pad might be the perfect solution.

Can you use a mattress pad and a mattress protector together?

Yes, you can absolutely use a mattress pad and a mattress protector together, and many sleepers do. Since each serves a different purpose, combining them allows you to enjoy the benefits of both. For the best results, place the mattress protector over both your mattress and mattress pad, then finish with your fitted sheet. This setup helps protect your mattress without sacrificing comfort.

What is a mattress topper?

As if distinguishing the difference between mattress pads and mattress protectors wasn’t hard, there’s also something called a mattress topper. A mattress topper is much more similar to a mattress pad than a mattress protector. A mattress topper is a thick layer of padding, typically made from memory foam, to increase the overall comfort of your bed.

How is this different from a mattress pad? Instead of fitting like a fitted sheet and draping over the sides, a mattress topper lies on top of your mattress and is held in place by a fitted sheet. Mattress toppers match the contours of your body to distribute support and reduce pain.

The Layla® Mattress Topper keeps you cool and cradled all night long with its copper gel beads that absorb body heat and redirect it away from you. It’s like adding an extra 2-inch layer of clouds to your bed that condenses under deep pressure points like your hips and shoulders to give you the best sleep possible. Even better, it’s antimicrobial, so it kills bacteria and other nasty microorganisms while you sleep. When you sleep with our cooling mattress topper, you’ll sleep deeper and longer every night of the week.

Mattress Pad or Mattress Protector? The Right Choice Depends on Your Needs

At the end of the day, mattress pads and mattress protectors aren’t competing products. They’re designed to solve different problems. If you’re looking to add a little extra softness, cushioning, or cooling to your bed, a mattress pad can help fine-tune your sleep experience. If your priority is protecting your mattress from spills, stains, allergens, and everyday wear, a mattress protector is a worthwhile addition. And for many sleepers, using both offers the best combination of comfort and protection, helping your mattress stay clean, comfortable, and supportive for many nights of sleep ahead.
