Sleeping hot has always been a problem for me, so I tried the Zinus 3 Inch Swirl Gel Cooling Topper to help cool things down.
It arrived in a small, easy-to-handle box, so moving it into the bedroom was hassle-free.
I unrolled it and waited about a day for it to fully expand and settle.
The gel-infused memory foam felt soft and supportive.
It noticeably reduced the heat buildup I’ve felt with other toppers.
The airflow design helped keep things cooler at night, though it may not be enough if you sleep very hot.
The topper fit nicely on my mattress and didn’t add much bulk.

Swirl Gel Cooling Technology
The gel inside the foam helped keep things cooler than a regular topper.

I felt less trapped heat compared to plain foam toppers.
The airflow reduced memory foam warmth without losing softness.
CertiPUR-US Certified Green Tea Memory Foam

Knowing it’s CertiPUR-US certified gave me confidence in the materials.
There was a faint new foam smell at first, but it disappeared after a couple of days.
The green tea infusion might help reduce odors, but I didn’t notice it directly.
