With pressure-activated cooling, the Cool Flash Sleeping Gel Body Pad is versatile and portable, offering cooling comfort wherever you need it.

Unlike traditional mattress toppers, the Cool Flash Sleeping Gel Body Pad exists specifically to provide cooling properties, rather than to add padding or cushion. This body pad measures 43.4 x 27.6 inches, making it ideal for personal use.

It's activated by pressure, and offers cooling relief for up to three hours – plenty of time to fall asleep, or to fall back asleep after waking up in the middle of the night. This pad doesn't require water, electricity, or refrigeration. When it's time to recharge the pad, simply let it sit in a cool place for 30 minutes.

This pad also has an advantage over traditional mattress toppers, in that it's easily portable. You can use it on the couch, in a recliner, or even while in a lounge chair outside for cooling relaxation.

Because the pad doesn't use water or electricity, it's safe to use in bed. You can lie directly on top of it, or place a sheet over it. For continuous cooling, invest in two pads so you can swap one out while the other recharges. For supercharged cooling, you can put the pad in the freezer prior to use.

The Cool Flash Sleeping Gel Body Pad has a 3.4 out of 5-star Amazon rating, based on 83 reviews. One reviewer named L. Capell wrote, "It doesn't stay cool for hours on end. But, I am able to make it several hours before I have to get up. And after a few minutes, it is cool again. Such a blessing for me!"

Another shopper named Sherri L. uses this pad for relief from night sweats: "Finally now at 50+ years old I find this and it is amazing the difference. I no longer have to get out of bed to let my pillow dry out. I place these on my pillow in such a manner as they will be under my neck and it is awesome."

Pros: No electricity, water, or refrigeration required; portable; recharges in 30 minutes

Cons: Cooling doesn't last all night
