Memory foam is popular in mattress toppers because it is inexpensive and good at relieving pressure. It is also the material most often blamed for a hot, sticky night. If heat is what puts you off, or what made you return the last one, there are two well-established alternatives and one compromise. Each has its own drawbacks, and we have set those out too.
Key takeaways
- Latex is the closest swap: breathable and springy, but heavier and usually dearer
- Wool regulates temperature best but adds little cushioning
- Gel or open-cell memory foam is cooler than plain foam, though it still holds some heat
- None of these will fix a mattress that has started to sag
Why memory foam sleeps warm
Memory foam softens as it warms and closes in around your body. That is what gives it its “hug”, and it is also why less air moves around you. The Sleep Foundation describes heat retention as the material’s biggest downside. Our guide to mattress topper problems covers that complaint and the others that come up most.
The Alternatives at a Glance
| Product | Best for | Main advantage | Main drawback | Price range | Where to buy |
|---|---|---|---|---|---|
| Latex | Hot sleepers who still want cushioning | Naturally breathable and long-lasting | Heavier and often more expensive | Higher | See on Amazon (opens in a new tab) |
| Wool | People who run hot and cold | Moves heat and moisture away | Little contouring or support | Higher | See on Amazon (opens in a new tab) |
| Gel or open-cell memory foam | Fans of the memory foam feel | Familiar pressure relief, lower price | Still retains some heat | Lower to mid | See on Amazon (opens in a new tab) |

Closest alternative
Latex toppers
Best for: Hot sleepers who want cushioning with some bounce
Latex is naturally breathable, and many latex toppers are ventilated with small holes to help air circulate. The feel is more of a buoyant float than a slow sink. Of the two main types, Talalay is lighter and more ventilated, while Dunlop is firmer and more durable.
Pros
- Does not hold heat the way memory foam does
- Springs back quickly, so it is easier to move on
- Among the longest-lasting topper materials
Cons
- Often more expensive than foam
- Heavy and awkward to move
- Not for anyone with a latex allergy unless a doctor says otherwise
Our take: The first thing to look at if heat is your main complaint and you still want real pressure relief.
Best for temperature
Wool toppers
Best for: Sleepers who are too warm in summer and too cold in winter
A wool topper is a quilted pad more than a slab of cushioning. It is the strongest option for regulating temperature, but if you were hoping to relieve pressure on your shoulders or hips it will not do much.
Pros
- Carries heat away when you are warm and insulates when you are cold
- Wicks moisture if you sweat at night
- Long-lasting
Cons
- Adds softness but little contouring or support
- Tends to cost more than foam
Our take: Choose it for temperature and comfort, not to change how supportive the bed feels.
The compromise
Gel-infused or open-cell memory foam
Best for: People who like the memory foam feel and are only slightly too warm
Manufacturers add cooling gel, perforations or a more open cell structure to help heat escape. Independent reviewers find these do help, while noting that some heat retention remains.
Pros
- Keeps the close, pressure-relieving feel
- Usually the least expensive of the three
Cons
- Cooler than plain memory foam, but still holds some heat
- Can still smell when new
- Cheap versions may not last
Our take: A sensible step if plain memory foam was nearly right for you. If you sleep very hot, skip to latex or wool.
What about certifications?
The CertiPUR-US mark you see on foam toppers applies only to polyurethane foam, including memory foam. It does not cover latex, so do not read anything into its absence on a latex topper. For latex and wool, bedding guides suggest looking for other third-party labels such as OEKO-TEX or GREENGUARD Gold.
How we chose these
This comparison is based on published guidance from independent bedding reviewers and from the foam industry’s certification body, not on our own hands-on testing. We chose materials, not brands, because the complaint we are answering, heat, comes from the material. We have not ranked individual products.
Is It Worth Buying?
Yes, if heat is your main complaint
If your memory foam topper is comfortable but too warm, moving to latex is the change most likely to help while keeping real cushioning. If you mainly want to stop overheating and are happy with how your mattress supports you, wool is the better fit. If you were only a little too warm, a gel or open-cell foam is the cheapest thing to try first.
Frequently Asked Questions
What is the coolest type of mattress topper?
Wool and latex are generally cooler than memory foam. Wool is best at regulating temperature and moisture, while latex is breathable and still provides cushioning.
Is latex better than memory foam?
It depends on what you want. Latex is more breathable, bouncier and longer-lasting, but it is heavier and usually costs more. Memory foam gives a closer hug and is cheaper.
Do cooling gel toppers actually work?
They help to a degree. Reviewers find gel-infused and open-cell foams sleep cooler than plain memory foam, but they still retain some heat.
