Quick Answer: Yes, you can put a mattress topper on a memory foam mattress. The best options are latex, gel-infused foam, or wool toppers that add cooling and responsiveness without fighting the foam underneath. Avoid stacking another memory foam topper on a memory foam mattress, as this creates excessive heat retention and sinking.

Why Add a Topper to a Memory Foam Mattress?
Memory foam mattresses do a lot of things well. They conform to your body, isolate motion, and relieve pressure points. But they are not perfect, and over time, certain issues tend to surface.
The most common reason people put a mattress topper on a memory foam mattress is heat. Traditional memory foam traps body heat because its dense cell structure limits airflow. If you find yourself waking up warm or flipping your pillow constantly, a cooling topper can make a real difference without replacing the entire mattress.
The second reason is firmness adjustment. Maybe your memory foam mattress felt perfect in the showroom but turned out to be too firm once you slept on it for a few months. Or maybe it has softened with age and you are sinking deeper than you used to. A topper lets you adjust the feel without spending $1,000 or more on a new mattress.
Why Memory Foam Sleeps Hot
Memory foam was originally developed by NASA in the 1960s for aircraft seat cushioning. Its viscoelastic structure responds to body heat by softening and conforming, which is what creates that signature cradling feel. The trade-off is that the same dense cell structure that enables conforming also restricts air circulation. Studies measuring mattress surface temperature show memory foam surfaces can be 3 to 5 degrees Celsius warmer than innerspring or latex surfaces after 30 minutes of sleep.
Other reasons people add a topper to a memory foam mattress include extending the lifespan of a mattress that is starting to show wear, adding a hypoallergenic barrier, or simply wanting a different feel on top without changing the underlying support system.
Best Topper Types for Memory Foam Mattresses
Not every topper material works well on top of memory foam. The goal is to complement the foam underneath, not duplicate its properties. Here are the options that work best.
Latex Toppers
Natural latex is the most popular choice for putting on top of a memory foam mattress, and for good reason. Latex is responsive and bouncy where memory foam is slow and conforming. It sleeps significantly cooler because its open-cell structure allows air to circulate. And it adds a slight lift that counteracts the "sinking in" feeling some people dislike about memory foam.
A 2-inch natural latex topper on a memory foam mattress creates a combination that many sleep experts consider ideal: pressure relief from the foam base with responsiveness and cooling from the latex surface. Expect to spend $200 to $500 for a quality queen-size latex topper in Canada.
Gel-Infused Foam Toppers
Gel-infused foam toppers use beads or swirls of cooling gel mixed into the foam to draw heat away from the body. They are more affordable than latex (typically $80 to $200 for a queen) and provide moderate cooling improvement. The cooling effect diminishes somewhat over a few hours as the gel absorbs heat, but for people who run warm during the first hour of sleep, this can be enough.
Wool Toppers
Wool is a natural temperature regulator. It wicks moisture away from your body and releases it into the air, keeping you warm in winter and cool in summer. A wool topper on a memory foam mattress adds breathability and moisture management that foam alone cannot provide. It also adds a plush, cushioned feel without the sinking sensation of foam-on-foam.
Quality wool toppers range from $150 to $400 for a queen. They are heavier than foam toppers and require occasional airing out rather than machine washing.
Down and Down-Alternative Toppers
Feather and down toppers add a soft, hotel-like pillow-top feel to any mattress. On a memory foam base, they create a luxurious surface layer while the foam handles support. They sleep cooler than foam-on-foam and are easily fluffed to maintain loft. The downside is that they do not provide much additional support, so they work best when your memory foam mattress still has good underlying structure but you want a softer surface feel.
| Topper Type | Cooling | Support | Price (Queen) | Best For |
|---|---|---|---|---|
| Natural Latex | Excellent | Very Good | $200-$500 | Hot sleepers, those who feel "stuck" in foam |
| Gel-Infused Foam | Good | Good | $80-$200 | Budget cooling upgrade |
| Wool | Very Good | Moderate | $150-$400 | Year-round temperature regulation, moisture wicking |
| Down/Down-Alt | Good | Low | $100-$350 | Adding plush surface feel, hotel-style comfort |
| Memory Foam | Poor | Good | $80-$250 | Not recommended on memory foam mattresses |
Toppers to Avoid on Memory Foam Mattresses
The most common mistake is stacking memory foam on memory foam. It seems logical, since you already like foam, but the combination creates problems.
Two layers of memory foam trap significantly more heat than one. The bottom layer's ability to respond to your body heat is muffled by the top layer, so you lose some of the contouring benefit while gaining all of the heat retention. You also create an excessively soft sleeping surface where your body sinks too deep, which can pull your spine out of alignment and cause back pain.
Common Topper-on-Foam Mistakes
Too thick: A topper thicker than 3 inches on a memory foam mattress creates a mushy, unsupported feel. Stick to 2 to 3 inches maximum. Too soft: If your foam mattress is already medium-soft, adding a soft topper makes the combined surface too plush for most body weights. Go one firmness level above what you think you want. No grip: Toppers slide on smooth memory foam surfaces. Use a topper with a non-slip bottom, or add a thin mattress pad between the topper and mattress for grip.
Choosing the Right Thickness and Firmness
Thickness and firmness depend on what problem you are trying to solve.
Topper Thickness Guide for Memory Foam Mattresses
- 1 inch: Minimal change. Adds a slight cooling layer or protective surface. Best when your mattress still feels right but runs warm.
- 2 inches: The most versatile option. Noticeable improvement in cooling and surface feel without significantly changing the mattress's support profile. This is what we recommend most often.
- 3 inches: Significant feel change. Appropriate when your memory foam is too firm and you want a softer sleeping surface, or when the foam has developed a body impression and you need to level the surface.
- 4+ inches: Rarely needed on a memory foam mattress. At this thickness, you are essentially sleeping on the topper rather than the mattress. If you need this much correction, it may be time for a new mattress.
Dorothy, Sleep Specialist at Mattress Miracle: "When someone comes in saying their memory foam mattress sleeps hot, the first thing I ask is how old it is. If it is under five years old and the support is still good, a 2-inch latex topper is usually all they need. If it is over eight years old and they are sinking into a body impression, a topper is just a bandage. That mattress needs replacing."
Mattress Protector vs. Mattress Topper: What Is the Difference?
These two products serve completely different purposes, and you should ideally have both on your memory foam mattress.
A mattress protector for memory foam mattress is a thin, fitted cover that goes directly over the mattress (and under any topper). Its job is to guard against spills, dust mites, allergens, and body oils that break down foam over time. A good protector is waterproof but breathable, adding virtually no change to the mattress feel. Expect to spend $40 to $100 for a quality protector.
A mattress topper sits on top of the protector and changes the sleeping surface. It adds cushioning, cooling, or firmness adjustment. Toppers range from 1 to 4 inches thick and cost $80 to $500 depending on material.
| Feature | Mattress Protector | Mattress Topper |
|---|---|---|
| Purpose | Protect mattress from damage | Change sleeping surface feel |
| Thickness | Paper-thin to 1/4 inch | 1 to 4 inches |
| Price (Queen) | $40-$100 | $80-$500 |
| Washable | Yes, machine wash | Most are spot-clean only |
| Waterproof | Usually yes | No |
| Changes Feel | Minimal to none | Significant |
| Placement | Directly on mattress | On top of protector |
The ideal layering order on a memory foam mattress is: mattress, protector, topper, fitted sheet. This arrangement protects the mattress from moisture damage while letting the topper do its job on the sleeping surface. For protector options, see our mattress protector and cover guide.
When to Replace Your Mattress Instead of Adding a Topper
A topper is a smart investment when your memory foam mattress still has structural integrity but needs a comfort adjustment. It is not a smart investment when the mattress itself is the problem.
Replace the mattress, not just add a topper, if you notice any of these signs:
- Visible body impressions deeper than 1.5 inches. Once the foam has permanently compressed this far, no topper can restore proper support. The foam's cellular structure has broken down.
- The mattress is over 8 to 10 years old. Memory foam degrades over time regardless of how well you maintain it. The fire retardants, antimicrobial treatments, and foam density all diminish with age.
- You wake up with back or hip pain that goes away during the day. This usually means the mattress is no longer supporting your spine properly. A topper can mask the sensation temporarily but does not fix the underlying alignment issue.
- You sleep noticeably better elsewhere. If hotel beds, guest rooms, or even your sofa provide better sleep, your mattress is the problem, not the surface layer.
Not Sure If You Need a Topper or a New Mattress?
This is one of the most common questions we hear at Mattress Miracle in Brantford. The honest answer is not always "buy a new mattress." Sometimes a $200 topper genuinely solves the problem and gives you another three to five years of comfortable sleep. Other times, adding a topper to a worn-out mattress is throwing good money after bad. Bring your questions to our showroom at 441 1/2 West Street, and we will help you figure out which situation you are in.
How to Care for Your Mattress Topper
A well-maintained topper lasts 3 to 5 years. Here are the basics.
Rotate your topper 180 degrees every month to distribute wear evenly. Spot-clean stains with a mild detergent and cool water, then let it air dry completely before putting sheets back on. Never put a foam or latex topper in the washing machine or dryer, as the heat and agitation will destroy the material.
Wool and down toppers can sometimes be professionally dry-cleaned, but check the manufacturer's care label first. Air your topper outside on a dry day once or twice a season to refresh it and eliminate odours. For cleaning tips, see our guide on how to clean mattress stains.

Can I put a memory foam topper on a memory foam mattress?
You can, but it is not recommended. Stacking memory foam on memory foam increases heat retention and can create an excessively soft surface that compromises spinal alignment. A latex, gel-foam, or wool topper is a better choice for a memory foam mattress base.
How thick should a mattress topper be for a memory foam mattress?
Two inches is the sweet spot for most people. It provides enough material to change the surface feel and improve cooling without overwhelming the support from the mattress underneath. Go to 3 inches only if your foam mattress feels significantly too firm.
Will a mattress topper void my mattress warranty?
No. Using a topper does not void mattress warranties. However, if your mattress develops a defect (like premature sagging), the warranty claim will be evaluated on the mattress itself, not the topper. Remove the topper before any warranty inspection so the assessor can examine the mattress surface directly.
Do I need both a mattress protector and a topper on my memory foam mattress?
Ideally, yes. The protector goes directly on the mattress to guard against spills and allergens. The topper goes on top of the protector to adjust comfort. The fitted sheet covers everything. This layering approach keeps the mattress clean while letting you customize the sleeping surface.

What is the best mattress topper for a queen memory foam mattress?
For a queen memory foam mattress, the best topper options are a 2-inch natural latex topper ($200-$400 for queen) for cooling and responsiveness, or a 2-inch gel-infused foam topper ($80-$200 for queen) for moderate cooling at a lower price. Both are available in queen size (60 by 80 inches) and avoid the "foam on foam" problem of stacking standard memory foam on top of a memory foam base.
Research published in Sleep Health (Radwan et al., 2015) on mattress surface design and sleep quality found that pressure distribution and conformity affect reported pain and sleep quality more than total bed thickness - meaning a thinner responsive layer over an aging memory foam base often does more than a thicker layer would. If your queen memory foam mattress sleeps hot, latex is the stronger choice.
If it feels too firm, a gel-foam or wool topper will add softness without dramatically increasing heat retention. Our So Sleepy 3" Latex Cooling Topper is the latex pick; the wider topper collection has gel-foam queens too.
What is a "cool" memory foam mattress topper, and does it actually cool the bed?
"Cool" memory foam mattress toppers fall into three real categories and one marketing one. Real cooling: gel-infused memory foam (gel particles or beads conduct heat away from the body modestly, lowering surface temperature 1-3°C compared to standard memory foam), copper-infused foam (copper particles in the foam matrix add similar conductivity), and phase-change-material toppers (active cooling layer that absorbs body heat for 20-30 minutes).
The marketing category: "cooling" branded on toppers that don't materially differ from standard memory foam - these often add a thin breathable cover and call it cooling.
The Canadian Sleep Society notes body-temperature drop is part of normal sleep onset, and bedding that traps heat interrupts the process - meaning the test isn't whether a topper feels cool when you first lie down (most do, briefly), but whether it allows continuous cooling through the second half of the night.
Honest framing: gel-foam and copper-foam toppers improve heat dissipation modestly versus standard memory foam; they do not actively cool the room. Dorothy mentions a practical bypass at our showroom: a thinner topper plus breathable cotton or bamboo sheets often runs cooler overnight than a thicker "cooling" topper alone, because the topper is closer to the cooler underlying mattress.
