I often sleep hot, so I tried the Zinus 1.5 Inch Swirl Gel Cooling Mattress Topper to see if it would help. The gel memory foam feels soft and supportive, and I noticed it kept heat from building up at night better than my usual mattress.
The topper arrived rolled in a box that I could handle easily. After letting it expand for about a day, it felt comfortable and didn’t add too much bulk to my bed.
Sometimes it still feels a little warm, but my sleep improved compared to using no topper.
Overview of the ZINUS 1.5 Inch Swirl Gel Cooling Memory Foam Mattress Topper
I used this mattress topper to add comfort without making my bed too thick. The 1.5-inch layer has gel swirled memory foam that helps keep me cool by improving airflow.
It molds to my body and eases pressure points, but stays soft enough to feel cozy. If you prefer firm support, this might feel too plush.
It expanded fully within a day after unboxing. The topper fits easily under most fitted sheets and is lightweight.
It’s not water resistant, so you need to clean up spills quickly.
Key Features
This topper changes how my mattress feels without needing a new one. After using it, I noticed some strengths and a few drawbacks.
Swirl Gel Cooling Technology
The gel swirls in the foam help with heat. I didn’t feel as hot lying on it compared to my old topper.
The foam hugs your body softly and isn’t too firm or too soft, which helped me sleep better.
Wave Dynamics Airflow Design
The unique design moves air through the topper, which keeps it from trapping heat for too long. I could feel some airflow, especially on warmer nights.
This airflow system helps stop that sticky feeling some foam toppers give after a while.
CertiPUR-US Certified Green Tea Memory Foam
The foam meets CertiPUR-US standards, which made me more confident about the materials. It didn’t give off strong chemical smells like some other foam products.
The foam uses green tea extract, which helps keep things fresh longer.
Expert Packaging and Easy Setup
The topper came in a compact box that I could carry easily. I just unrolled it and let it expand.
It took about a day to fully expand. There was no tricky assembly, which saved me time.
Pros and Cons
After using this topper for a while, I found clear strengths and some downsides.
Pros
The topper feels soft and supportive, improving the comfort of my old mattress without being bulky. The gel swirl helps with temperature regulation, making it cooler to sleep on.
It was easy to unpack and set up, expanding to full size quickly. It fits well under normal sheets, so there’s no hassle with fabric bunching up.
Its CertiPUR-US certification gave me more confidence about the material quality.
Cons
The 1.5-inch thickness might be too thin for people needing extra cushioning or support. The cooling effect isn’t perfect—on very warm nights, it still felt a bit warm.
Some people have mentioned odors or staining issues, but I didn’t experience those. The topper took about a day to fully decompress, so you need to wait before using it.
If you prefer a more cloud-like softness, this might feel a little firm.

It doesn’t completely eliminate warmth, but it improves airflow compared to my old foam layer. The 1.5-inch thickness adds comfort without making the bed too soft or hot.
It takes about a day to fully expand and start working well, so patience is needed after unboxing.
