Our pick is the Brooklyn Bedding Microcoil topper: a cool-to-the-touch cover plus airflow through open-cell foam and microcoils. Choose Helix if you want a longer trial, Saatva for pressure relief, Nectar for value at $199, and Nolah for a plush premium feel.
- A topper changes more than temperature: 3 inches of foam can soften your bed and make it harder to move on.
- Return windows vary a lot: 30 days for Brooklyn Bedding and Nolah, 100 nights for Nectar, 180 for Saatva, a long trial for Helix.
- Queen prices at the time of review ranged from $199 (Nectar) to about $660 before promotion (Brooklyn Bedding).
- None works like air conditioning, and these five weren't measured together under the same conditions.

If your mattress still feels comfortable but you keep waking up hot, replacing the whole bed is an expensive fix for one problem. A cooling topper sounds perfect: a cooler surface on the bed you already like. The catch is that a topper changes more than temperature. Three inches of foam can make your bed softer, harder to move on, and sometimes warmer once the cool-to-the-touch feel wears off.
We narrowed it down to five cooling toppers and looked at how each handles heat, how much it changes the feel of the bed, who it suits and the limitation to know before buying.
Quick verdict
Buy the Brooklyn Bedding Microcoil to fight trapped heat: soft if your mattress is too hard, firm if you need more support. Choose Helix if the 30-day Brooklyn window feels too risky, Saatva for pressure relief, Nectar for value, and Nolah for a plush premium feel if you don't need strong edges.

How cooling toppers actually work
A cool-to-the-touch cover moves heat away from your skin while you're touching it. Graphite and gel are added to foam to spread heat instead of letting it collect in one spot. Open-cell foam and microcoils work differently: they create more room for air to move, so the topper traps less heat in the first place. None works like air conditioning, and these five weren't measured together under the same conditions, so we compare how each design works, how much it changes your mattress, and what happens if it doesn't work for you.
1. Brooklyn Bedding Microcoil Topper: best overall
The GlacioTex cover gives a cool first touch, while open-cell foam and microcoils leave space for heat to escape after the surface warms up: one of the most complete cooling designs here. It's 3.75 inches thick, so you'll feel more than a temperature change. Independent testing of the soft version took a medium-firm bed from about 6.5 out of 10 to roughly 5. Choose soft if your mattress feels hard at the shoulders and hips; choose firm if you want to stay on top, sleep on your stomach or need a stronger edge. The cover is machine washable.
A queen listed for about $660, or $495 with a 25% promotion, with free shipping and a 3-year warranty. The catch: only 30 days to return it. The one-year mattress trial doesn't apply. Unpack it straight away and judge both temperature and firmness quickly.
2. Helix Premium Topper with GlacioTex: best for a longer trial
Similar design to the Brooklyn Bedding: GlacioTex cover, foam and microcoils, 3.75 inches thick. The bigger decision is feel, and the luxury plush and luxury firm names don't tell the whole story. If your mattress is already soft and your hips sink, choose luxury firm; if your bed feels hard and you mainly sleep on your side, luxury plush. Helix offers a long home trial with free returns and asks you to keep the topper at least 30 days so the foam can settle.
Helix showed $349 when we checked, but the page didn't make clear which size that covered; other sources put a queen closer to $499, so go by the checkout total. The warranty is 1 year, and treat the cover as spot clean only. The firmness is less predictable, and the long trial is what makes that manageable.
3. Saatva Graphite Memory Foam Topper: best for pressure relief
For someone who wants a firm mattress to feel more forgiving but worries about sleeping hot on memory foam. At 3 inches it gives a slow, body-hugging feel around the shoulders, hips and lower back. Stomach sleepers and anyone who hates sinking should skip it, since the hips may settle too far. Graphite spreads heat, but independent reviews disagree on how much it helps: one found the surface stayed cool, another still woke up hot. Buy it for pressure relief, not to feel cold all night.
Saatva listed the queen for $305 (you may see $445 elsewhere), with a 180-night home trial, full refund and free return shipping. There are no direct exchanges, so a different size means returning and reordering. Warranty is 1 year.
4. Nectar Softer Topper: best value
The budget choice for a side sleeper whose shoulders or hips press into a mattress that feels too hard. Make sure you choose the softer version; Nectar sells a separate firmer one. It adds 2 inches of gel memory foam, and in independent testing it scored 5 out of 5 for motion isolation, good if a partner turning over usually wakes you. Open-cell foam and cooling yarns aim to reduce heat build-up, but cushioning is the main reason to buy it. On an already soft bed, or for back and stomach sleepers, the extra sink can let the hips drop.
Nectar and Walmart listed the queen at $199, the lowest in the group. You get 100 nights (ignore the 365-night banner, which applies to mattresses); promotional or free toppers aren't returnable. Rely on a 1-year warranty, the cover is spot clean only, and the new-foam smell may need a few days to air out.
5. Nolah AirFoam Lux: best plush premium option
A premium choice for side and back sleepers who want a softer, more cradling bed. Make sure the name includes "Lux"; Nolah's cheaper standard topper is a different product. Choose 2 or 3 inches of foam and an organic cotton or GlacioTex cover. For cooling, choose GlacioTex, since the cotton option doesn't make the same heat-transfer claim. The foam settles around the shoulder and hip and keeps movement on one side, but it compresses easily at the edge, so skip it if you sleep against the side or need a firm edge to stand up.
The 2-inch queen listed at $499, about $349 with a standing 30% sale. The catch: 30 days to return and you pay return shipping, and one reviewer reported the new-foam smell took about 30 days to fade. The foam has a 10-year warranty but the cover only 1 year.

Frequently asked questions
Do cooling mattress toppers actually work?
They can help, but none works like air conditioning. Designs that combine a cool-to-the-touch cover with airflow inside the topper, like the Brooklyn Bedding Microcoil, give heat more than one way to escape.
What's the best cheap cooling topper?
The Nectar Softer topper at $199 for a queen, though its main benefit is cushioning for side sleepers rather than strong cooling.
Will a topper make my mattress softer?
Usually yes. Independent testing found the Brooklyn Bedding soft topper took a medium-firm bed from about 6.5 out of 10 to roughly 5. Choose a firm version if you don't want that.
Which cooling topper has the longest trial?
Helix offers a long home trial with free returns, and Saatva gives 180 nights. Brooklyn Bedding and Nolah give only 30 days.
