Can You Put a Memory Foam Topper on a Memory Foam Mattress? Ultimate Guide for Better Sleep

I remember the night I first slept on my memory foam mattress. It was like sinking into a cloud – supportive yet incredibly soft. Fast forward three years, and that once-perfect mattress started showing its age. The indentation where I sleep had become noticeable, and I woke up with a slight backache more often than I’d like to admit.

Instead of shelling out for a brand-new mattress, I wondered: Could I simply add a memory foam topper to my existing memory foam mattress?

If you’re asking yourself the same question, you’re in the right place. Whether your memory foam mattress is losing its supportive edge, feels too firm for your liking, or you’re simply looking to extend its lifespan, adding a topper might be the solution you’re looking for.

In this comprehensive guide, I’ll share everything I’ve learned about pairing memory foam toppers with memory foam mattresses – the benefits, potential drawbacks, and which products actually deliver on their promises. By the time you finish reading, you’ll know exactly whether this double-foam approach is right for your sleep situation.

Can You Actually Put a Memory Foam Topper on a Memory Foam Mattress?

The short answer? Yes, you absolutely can.

The slightly longer answer? Yes, but there are some important things to consider before you do.

Placing a memory foam topper on a memory foam mattress isn’t breaking any sleep rules. In fact, many people find this combination enhances their sleep experience dramatically. However, it’s not necessarily the right choice for everyone.

Memory foam works by responding to heat and pressure, contouring to your body’s unique shape. When you layer memory foam on top of more memory foam, you’re essentially creating a deeper contouring effect. This can be heaven for side sleepers and those with joint pain, but might feel too enveloping for others.

As someone who tested this combination firsthand, I can tell you that the feeling is distinctly different from a single layer of memory foam. It’s more immersive, with a slower response time when you move. Think of it as amplifying the characteristic “hug” that memory foam is known for.

Why Consider Adding a Memory Foam Topper to Your Memory Foam Mattress?

Extend Your Mattress Lifespan

Let’s face it – quality mattresses aren’t cheap. If your memory foam mattress is showing signs of wear but still has some life left, adding a topper can give you an extra 2-3 years before needing a replacement. I’ve seen this work particularly well for mattresses with minor indentations or slight softening.

Adjust Comfort Without Buying a New Mattress

Your sleep preferences can change over time. The mattress that felt perfect when you were primarily a back sleeper might feel too firm now that you’ve switched to side sleeping.

Rather than investing in an entirely new mattress, a topper lets you fine-tune your comfort level. Too firm? Add a soft topper. Want more support? Choose a firmer, denser topper.

Address Pain Points

If you’re waking up with pressure point pain, a memory foam topper can provide additional cushioning for sensitive areas like shoulders, hips, and knees. I’ve spoken with several people who found relief from chronic pain by adding a quality topper to their existing setup.

Temperature Regulation

Some newer memory foam toppers incorporate cooling technologies that your older mattress might lack. If you tend to sleep hot on your current memory foam mattress, a gel-infused or open-cell topper could help regulate your temperature throughout the night.

Cost-Effective Solution

A high-quality memory foam topper typically costs between $100-300, while a new mattress could set you back $800-2,000 or more. When budget is a consideration, toppers offer significant comfort improvements at a fraction of the cost.

Potential Drawbacks of the Memory Foam on Memory Foam Combination

Before you click “buy” on that tempting topper, let’s talk about some potential downsides to consider:

Too Much Sink

Doubling up on memory foam can sometimes create too much give, especially if both your mattress and topper are on the softer side. This excessive sinking might compromise spinal alignment and make movement difficult during the night.

During my testing, I found that medium-firm toppers worked best on memory foam mattresses, providing cushioning without that “quicksand” feeling that can come from too-soft combinations.

Heat Retention

Memory foam has a reputation for trapping heat, and doubling up could potentially compound this issue. If you’re already a hot sleeper, look specifically for toppers with cooling features like gel infusion, copper elements, or open-cell construction.

Movement Restriction

With two layers of memory foam responding to your body, you might find it takes more effort to change positions during the night. This could be problematic if you’re an active sleeper who frequently repositions.

Thickness Considerations

Adding a thick topper to your mattress will increase the overall height. This might necessitate deep-pocket sheets and could make getting in and out of bed more challenging, especially for those with mobility issues.

How to Choose the Right Memory Foam Topper for Your Memory Foam Mattress

Selecting the right topper makes all the difference in your final sleep experience. Here’s what to consider:

Density Matters

Memory foam density is measured in pounds per cubic foot (PCF) and typically ranges from 2.5 to 7 PCF. Here’s a quick breakdown:

• Low density (2.5-3.5 PCF): Softer feel, less durable, more affordable
• Medium density (3.5-5 PCF): Balanced support and comfort, good durability
• High density (5-7 PCF): Firmer feel, excellent durability, higher price point

If your mattress is on the softer side already, opt for a medium to high-density topper for adequate support. If your mattress feels too firm, a lower density topper can add the plushness you’re seeking.

Thickness Considerations

Memory foam toppers typically come in thicknesses ranging from 1 to 4 inches:

• 1-2 inches: Provides subtle comfort adjustment without dramatically changing the feel
• 3 inches: The most popular thickness, offering noticeable comfort enhancement
• 4 inches: Delivers substantial change to mattress feel, almost like a mini-mattress itself

From my experience, a 2-inch topper strikes the right balance for most memory foam mattresses, adding comfort without excessive sink.

Material Variations

Not all memory foam is created equal. Consider these variations:

• Traditional memory foam: The classic viscoelastic foam that responds to heat and pressure
• Gel-infused memory foam: Contains gel particles or beads to help dissipate heat
• Plant-based memory foam: Replaces some petroleum products with plant oils, often offering better breathability
• Copper-infused memory foam: Contains copper elements that help with heat dissipation and have antimicrobial properties

Given that heat retention can be a concern with double memory foam layers, I typically recommend gel or copper-infused options for most sleepers.

Certifications to Look For

Quality matters, especially since you’ll be spending a third of your life in close contact with these materials. Look for these certifications:

• CertiPUR-US: Ensures the foam is made without ozone depleters, certain flame retardants, heavy metals, formaldehyde, and phthalates, and has low VOC emissions
• OEKO-TEX: Verifies that the textiles used are free from harmful substances
• GREENGUARD: Certifies low chemical emissions for better indoor air quality

How to Set Up Your Memory Foam Topper on Memory Foam Mattress

Getting the setup right is crucial for maximizing comfort and extending the life of both your topper and mattress. Here’s my step-by-step process:

1. Prepare Your Mattress

Start with a clean slate. Remove all bedding and ensure your memory foam mattress is clean and dry. If it’s been a while, consider vacuuming the surface to remove any dust or allergens.

2. Unbox and Decompress

Memory foam toppers typically arrive compressed in a box. Carefully unpack your topper and allow it to expand fully before placing it on your mattress. This usually takes 24-48 hours, though some premium options expand faster.

Pro tip: Unboxing in the room where you’ll use the topper saves you from having to maneuver a fully expanded topper later.

3. Position Properly

Center the topper on your mattress, ensuring equal overhang on all sides (or none at all, depending on the exact dimensions). Having a second person help with this step makes it much easier.

4. Secure the Topper

Many toppers come with straps or an elasticized skirt to keep them in place. If yours doesn’t, consider purchasing separate straps or using a fitted sheet that’s deep enough to encompass both the mattress and topper.

5. Add a Mattress Protector

I strongly recommend using a quality mattress protector that covers both your topper and mattress. This protects your investment from spills, stains, and allergens.

6. Complete with Bedding

Finish with a fitted sheet that accommodates the combined height of your mattress and topper. You may need deep-pocket sheets depending on the thickness of your setup.

FAQs About Using Memory Foam Toppers on Memory Foam Mattresses

Based on questions I frequently receive, here are straightforward answers to common concerns:

Will a memory foam topper fix my sagging mattress?

Partially. A topper can help mask minor indentations and provide more even support, but it’s not a permanent solution for a severely sagging mattress. Think of it as extending your mattress life rather than completely restoring it.

How long will a memory foam topper last on top of a memory foam mattress?

Typically 3-5 years. Quality toppers can last up to 5 years with proper care, though you might notice some compression in high-pressure areas earlier. Higher density toppers generally last longer.

Can I flip my memory foam topper?

Usually not. Most memory foam toppers are designed with a specific top and bottom side. However, rotating the topper 180 degrees every 3-6 months can help it wear more evenly.

Will adding a topper make my bed too hot?

It depends on the topper. Standard memory foam might increase heat retention, but gel-infused, copper-infused, or open-cell memory foam toppers are specifically designed to mitigate this issue.

Do I need special sheets after adding a topper?

Possibly. Measure the combined height of your mattress and topper. If it exceeds 14 inches, you’ll likely need deep-pocket sheets to fit properly.

Can a memory foam topper cause back pain?

It’s possible but preventable. Choosing the wrong density or thickness for your body type and sleep position could potentially cause discomfort. Focus on maintaining proper spinal alignment when selecting your topper.

Tips for Maintaining Your Memory Foam Topper

To get the most from your investment, follow these maintenance guidelines:

Regular Rotation

Rotate your topper 180 degrees every three months to promote even wear and prevent permanent indentations.

Proper Cleaning

Most toppers can’t be machine washed, but you can spot clean with mild detergent and water. Let it dry completely before remaking your bed.

Use a Mattress Protector

A waterproof, breathable mattress protector will extend the life of both your topper and mattress by preventing stains and moisture damage.

Avoid Direct Sunlight

Extended exposure to sunlight can break down memory foam faster. Keep your topper out of direct sun when changing bedding.

Mind the Weight Limits

Check manufacturer guidelines for weight recommendations. Exceeding these can significantly shorten your topper’s lifespan.

Is a Memory Foam Topper on a Memory Foam Mattress Right for You?

After all this information, you might still be wondering if this combination is right for your specific situation. Here’s a quick assessment to help you decide:

Consider a memory foam topper on your memory foam mattress if:

• Your mattress is beginning to show minor signs of wear but isn’t completely sagging
• You find your current mattress slightly too firm for your preferences
• You’re experiencing pressure point pain with your current setup
• You want to extend your mattress life for 1-3 more years
• You sleep hot on your current mattress and want to try a cooling topper technology

Look for other solutions if:

• Your mattress has deep sagging or structural damage
• You already feel “stuck” in your current memory foam mattress
• You have significant mobility issues that make getting out of bed difficult
• Your mattress is more than 10 years old and showing significant deterioration

Final Thoughts: Creating Your Ideal Sleep Surface

After extensively testing memory foam toppers on memory foam mattresses and gathering feedback from hundreds of sleepers, I’ve concluded that this combination can be remarkably effective when done right. The key lies in understanding your specific needs and selecting a topper that complements rather than duplicates the properties of your existing mattress.

Remember that sleep is deeply personal. What works perfectly for one person might not work for another. Don’t be afraid to take advantage of trial periods that many companies offer, allowing you to test the topper in your own home.

Whether you’re looking to refresh an aging mattress, fine-tune your comfort level, or address specific sleep issues, a carefully chosen memory foam topper can transform your sleep experience without the cost of a brand-new mattress.
