Waking up in a pool of sweat is miserable, and it is often the mattress, not you, that is trapping all that heat. A cooling mattress topper adds a layer of gel-infused or breathable foam that pulls warmth away from your body, so you actually stay asleep instead of flipping pillows at 3 a.m.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
For a genuinely cooler night’s sleep, the right cooling mattress toppers depend on thickness, gel infusion, and washable covers that actually fit your bed.
Our Picks at a Glance
How To Choose The Best Cooling Mattress Toppers
Not every “cooling” topper actually keeps you cool. Some just have the word printed on the box, while others use real heat-dissipating materials. Knowing the difference helps you spend money on what actually works.
Thickness: The Trade-Off Between Softness and Heat
A 2-inch topper adds a gentle layer of comfort without changing the feel of your mattress much. A 3-inch topper gives you deeper cushioning for pressure relief but can trap more heat if the foam isn’t well-ventilated. A 4-inch dual-layer option offers the plushest feel but takes longer to air out and expand.
Cooling Technology: Gel, Copper, or Bamboo Covers
Gel-infused foam absorbs and redistributes body heat, while copper-infused foam conducts warmth away. A breathable cover made of bamboo-derived fabric helps air flow, and ventilation holes in the foam push heat out so you don’t wake up damp.

In-Depth Reviews
1. Linenspa Memory Foam Mattress Topper, Queen Size – 2 Inch Gel Infused
Our pick — 4.5★ from 74,500+ verified ratings; the strongest balance of quality and price.
The crowd favorite that turns a rock-hard mattress into a pressure-relieving cloud while staying affordable.
What wins people over here is the comfort — the plush gel-infused foam conforms to your curves and is CertiPUR-US certified, meaning it uses quality materials for safety and durability. One popular use case is softening an overly firm mattress, with buyers reporting that it relieves hip pain and reduces morning stiffness without losing the mattress’s underlying firmness.
The cooling gel helps capture and distribute heat, so owners note less sweating at night. It arrives compressed; you unroll it and watch it expand fully in 24-48 hours. Some buyers mention a faint initial odor that fades, while others notice no smell at all — opinions are split, but the comfort and pressure relief get consistent praise.
Compared to the 3-inch options below, this 2-inch profile is the lighter, more subtle upgrade that keeps your mattress’s original feel intact. The trade-off is a minor one: a few owners find the edge support a bit weak and the topper too soft if you prefer a firmer sleep surface.
Why It’s a Winner
- Gel infusion helps distribute heat so you sleep cooler
- CertiPUR-US certified for quality materials and safety
- Expands quickly in 24-48 hours with simple setup
Watch Out For
- Some owners find edge support a bit weak
- Initial faint odor varies from one unit to the next
Grab this if: you want a proven, budget-friendly way to soften a firm mattress and relieve pressure points without committing to a thick, plush layer.
Think twice if: you are a firmness purist who wants a topper that keeps the mattress feeling hard — this one leans plush.
2. MLILY 3 Inch Egg Crate Full Memory Foam Mattress Topper, Lavender Scent Gel Infused
The egg-crate design that relieves hip and joint pain while keeping you cool through summer nights.
The egg-crate shape creates tiny channels on the surface that promote airflow, which is exactly why buyers report sleeping cool even in warm weather. The 3-inch profile offers a firm-yet-soft feel for spinal alignment, while CertiPUR-US certified foam contours to relieve pressure points.
What buyers appreciate most is the subtle lavender scent — it maintains a calming environment without the strong chemical stink that some foams have. Many note it expands fully in about 20 minutes, which is notably quicker than most toppers. One practical use-case: an owner cut a queen size in half for RV bunks, finding the dense foam a cheap way to upgrade low-quality RV mattresses, though they warned against leaving it in a hot RV due to heat deformation risk.
Compared to the Linenspa above, this one is thicker and has that distinctive egg-crate airflow design, making it a better choice for hot sleepers who also want pressure relief. A minor note: some owners find it slightly warm despite the cooling gel, and the initial smell can be strong until aired out.
Standout feature: the egg-crate design promotes airflow better than flat foam, helping you sleep cooler.
Real-world fit: best for side sleepers with hip or joint pain who want a supportive, not overly soft, 3-inch layer.
3. MLILY 3 Inch Queen Cooling Gel Infusion Memory Foam Mattress Topper
A soft yet resilient 3-inch layer that revives an old mattress with proper airflow built in.
The ventilated design promotes air circulation to dissipate heat, which owners say prevents morning soreness. The gel-infused foam provides pressure-relieving support, backed by CertiPUR-US certification for quality and performance. Many buyers use it to extend the life of an old mattress rather than buying a new one.
Setup is genuinely fast — the topper arrives compressed, rolled, and in a compact box, with installation you can complete in about 3 minutes. One buyer moved from a super soft bed to a firm one and found this topper “saved the day,” noting it’s not so soft you sink in but soft enough to support you. Another mentioned the 2-inch twin version had no smell at all, though some owners do note a sparkly shimmer on the foam that transfers if handled too long.
Compared to the egg-crate MLILY above, this one has a plush or soft firmness rather than the supportive egg-crate feel, making it better for those who want more cushioning. The honest trade-off: softness gets mixed feedback, with some wishing it were firmer.
Reach for this if: you want a plush 3-inch topper with good airflow that makes a firm or aging mattress feel luxurious again.
Look elsewhere if: you need a firm, supportive surface — this one leans soft and cushioned.
4. EGOHOME 3 Inch Queen Memory Foam Mattress Topper with Removable Cover
The precision-support topper with a washable cover that keeps things clean and stable all night.
What stands out here is the removable polyester cover with a zipper, so you can wash it easily and prevent dust buildup — a feature many toppers lack. The design precisely adjusts to body curves, supporting the spine and common pressure points to eliminate morning soreness. The back of the cover has a non-slip net structure plus four adjustable elastic straps to hold everything in place.
Advanced gel cooling absorbs heat and disperses it through ventilation holes, helping owners fall asleep quickly and wake refreshed. Both CertiPUR-US and OEKO-TEX certifications back the materials. The thing everyone raves about is the comfort — 173 owners single it out as the top positive aspect — but the fit gets mixed feedback, with some saying it slides off the mattress despite the straps.
Compared to the Linenspa, this 3-inch option adds a washable cover and those non-slip straps, making it a better choice for restless sleepers. The catch: some owners found the straps poorly placed and prone to popping off, and one noted a middle hump developing after a month of use.
Loved For
- Removable, machine-washable cover keeps things hygienic
- Non-slip bottom with four adjustable straps for stability
- Ventilation holes aid heat dispersal for cooler sleep
Keep In Mind
- Some owners mention the straps pop off or the topper slips
- A few note a middle hump developing after regular use
5. Czpalo 3 Inch Twin XL Cooling Gel Memory Foam Mattress Topper
The Twin XL with a bamboo cover and sliding straps that hold firm even on high mattresses.
This topper pairs 3 inches of gel-infused memory foam with a removable, washable cover made from 60% polyester and 40% bamboo fiber. The bamboo fabric is breathable, helping regulate temperature and dissipate heat for a cooler sleep environment. The adjustable elastic straps with slide attachments are strong enough to fit high mattresses, and the non-slip mesh bottom keeps everything in place.
Owners specifically praise how the straps reach the edges of a California King and hold securely, and the firm, gel-like comfort is great for hip pain relief. Expansion takes 24-48 hours, and customers note minimal to zero odor after airing it out. One honest note from a buyer who found it “very very firm”: it’s well-made and had zero smell, but they were personally looking for something softer — so this leans medium-firm.
Compared to the EGOHOME above, this one’s cover is bamboo-based rather than polyester, which adds extra breathability for hot sleepers. The trade-off is the firmness — if you sink into soft foam, this medium-firm feel might take some getting used to.
Best fit: hot sleepers and hip-pain sufferers who want a breathable bamboo cover and straps that genuinely stay put on thick mattresses.
Fair warning: it runs medium-firm, so if you want a sink-in cloud, this is firmer than expected.
6. Bedlore King Size Mattress Topper 4-Inch Memory Foam Dual Layer
A plush 4-inch dual-layer topper that turns a rock-hard mattress into a genuinely comfortable sleep.
The 4-inch design stacks 2 inches of gel-infused memory foam with a 2-inch pillow top, giving you deep pressure relief that distributes weight evenly across hips, back, and neck. The breathable viscose derived from bamboo fabric keeps the surface comfortably cool all night, which owners say makes a hard mattress “useable” and helps with back pain. The elastic deep pocket fits mattresses up to 18 inches, so it stays secure even during restless nights.
This is a vacuum-packed topper, so you’ll want to leave it in a well-ventilated place for 24-72 hours to let the foam expand and any smell dissipate. One owner with rheumatoid arthritis reported their body pain “goes away,” allowing side sleeping without shoulder and hip pain. The thing everyone raves about is the comfort, with 88 owners highlighting it, though firmness gets mixed feedback — some find it too soft.
Compared to the 2-inch Serta below, this is a much thicker, plusher option that adds real cushioning rather than just a subtle layer. The trade-off is the waiting time — it needs longer to fully expand and fluff up before you get that luxurious feel.
Biggest Strengths
- 4-inch dual-layer gives deep, plush pressure relief
- Deep pocket fits mattresses up to 18 inches
- Bamboo-derived fabric keeps you cool all night
Before You Buy
- Needs 24-72 hours to fully expand and air out
- Firmness is mixed — some owners find it too soft
Perfect for: back-pain sufferers and side sleepers who want a plush, thick layer that makes a hard mattress feel brand new.
Not for: anyone who needs immediate use — this one needs a couple of days to fully fluff up.
7. Serta CopperGel Cooling, Pressure-Relieving Memory Foam Mattress Topper, 2 Inch, King
The 2-inch king topper that uses conductive copper to channel heat away from your body.
This one takes a different approach to cooling: instead of just gel infusion, it combines the conductive power of copper with gel-infused foam for temperature-regulating comfort. The heat-dissipating copper gel beads channel warmth away from your body while offering adaptive, conforming support. It’s also made in the USA, which some buyers appreciate for quality and durability.
Owners highlight how it relieves pressure points for side sleepers and helps with back pain — one buyer’s son, a 6’8″ flight nurse with back issues, found it helped relieve his pain so much. The softness gets mixed feedback, with some finding it good and others too soft. A fair number mention an initial foam smell that dissipates after a few hours of airing out, and one skeptical owner noted the foam seems to lack the copper they expected.
Compared to the 4-inch Bedlore above, this is a slim 2-inch layer that won’t dramatically change your mattress’s feel — it just adds a cooling, pressure-relieving surface. The honest trade-off: cooling gets mixed reviews, with some saying it’s “not hot, not cooling,” so it may not be the chilliest option on this list.
Who it suits: side sleepers and back-pain sufferers who want a subtle 2-inch upgrade with copper-based cooling.
Who should pass: hot sleepers expecting dramatic cooling — reviews are mixed on how much heat it actually pulls away.
8. PERLECARE Queen Mattress Topper – 3 Inch Cooling Memory Foam with Bamboo Cover
The 3-inch topper with silicone non-slip points that stays put even for the most restless sleepers.
What sets this one apart is the bottom design — it uses non-slip silicone points plus four fixing straps to keep the topper firmly in place, reducing the hassle of constantly adjusting it. The 70% polyester and 30% bamboo fiber cover is breathable and machine washable with a zipper for easy removal. The 3-inch cooling gel foam uses ventilation holes and breathable mesh to accelerate air flow and heat exchange for a cooler night.
Reviewers point out excellent back-pain relief, with some achieving a full night of uninterrupted sleep for the first time in a year. The CertiPUR-US certified foam is skin-friendly and free from harmful ingredients. One reviewer noted it supports heavy users without sinking, though they found it slightly warm. The recurring gripe is the fit — while many say it stays in place, others report it slips out of position, so the straps may not work for every mattress depth.
Compared to the EGOHOME, this one adds silicone points for extra grip, making it a better pick if you toss and turn. The trade-off: softness gets mixed reviews, with some buyers wishing it were firmer.
Why People Pick It
- Non-slip silicone points and four straps for stability
- Machine-washable bamboo cover with zipper
- Ventilation holes and breathable mesh for airflow
Watch For
- Fit is mixed — some report it slipping out of place
- Cooling gets mixed feedback with some finding it warm
9. BEDLORE 4 Inch Dual Layer Memory Foam Mattress Topper King
The adjustable 2-in-1 topper that lets you switch between firm support and plush cushioning.
This is the rare topper you can customize: switch between the 2-inch cooling gel memory foam for firm support and the 2-inch plush pillow top for pressure relief — or layer them both for a 4-inch luxury upgrade. The bamboo viscose cover plus open-cell foam boosts airflow to prevent overheating, so owners say it “fixed my saggy mattress” and keeps their body cool. The stretchy deep-pocket design fits mattresses 6 to 18 inches and stays put.
It ships flat in a vacuum pack, so you unroll it and let it air out for 24-72 hours to fully expand. Shoppers say it’s just firm enough to fix a sagging mattress, conforms to the body, and is great even for camping. Both OEKO-TEX and CertiPUR-US certifications back the materials. The thing everyone raves about is the comfort — 114 owners highlight it — though softness and fit get mixed feedback, with some finding it not as advertised.
Compared to the other Bedlore 4-inch above, this one offers the adjustable layering option, giving you control over firmness rather than a fixed feel. The honest trade-off: at 4 inches with a pillow top, it’s a significant change to your bed’s height and feel, and some found a slight corner overhang.
Why it’s special: the 2-in-1 design means you can sleep on firm gel foam one night and plush pillow top the next — or combine them for maximum cushion.
Keep in mind: it needs 24-72 hours to expand, and the extra thickness changes how your fitted sheets fit.
Understanding the Specs
Gel Infusion vs. Copper Infusion
Gel-infused foam has tiny gel beads mixed in that absorb and redistribute body heat, keeping the surface cooler. Copper-infused foam uses the conductive properties of copper to channel warmth away from your body. Both work, but copper is often marketed as more effective for heat dissipation, while gel is more common in budget-friendly options.
Thickness and Your Mattress Type
A 2-inch topper adds a subtle layer of comfort without changing your mattress’s feel — good for softening a slightly firm bed. A 3-inch topper provides deeper pressure relief for side sleepers and those with hip or back pain. A 4-inch dual-layer topper offers the plushest feel but takes longer to expand and adds noticeable height, so check that your fitted sheets can still fit.
