If you think you’ve tried everything to get a good night’s sleep, you might want to consider using a mattress cooling pad. They typically go under your fitted sheet and chill water before sending it through tubes in the pad to maintain the temperature you set. Some use a fan to blow air in your bed to cool you off, and some can also heat up your bed for those cold winter nights. Prices for the models we tested range from $155 to $1,500 for a dual-zone California king.

Why does it matter if you have a cool environment? Science says that many people sleep better that way. The National Sleep Foundation recommends keeping your room temperature around 65° F.

But the ideal temperature varies from person to person. “We know you get the most deep sleep in a cool bedroom—not cold, but cool,” says Philip Richard Gehrman, PhD, an associate professor of clinical psychology at the Hospital of the University of Pennsylvania in Philadelphia. “The problem is what’s cool to one person is not cool to another person.”

There is at least some evidence that the pads might keep you chilled. “Studies were done years ago on whether passive cooling induced sleep, but they used cooling gloves that people wore before bed, and results were mixed,” Gehrman says. “A cooling pad would impact more surface area of the body and presumably would be more effective.”

Finding the right sleep temperature is such a prevalent point of discussion that it has become a recurring theme on some popular podcasts. “Several of my close friends in Silicon Valley sheepishly admitted that, of all the advice I’ve ever given in my books and podcasts, the ChiliPad had the biggest impact on their quality of life,” podcaster Tim Ferriss wrote in his book “Tools of Titans” (Houghton Mifflin Harcourt, 2016).

But that doesn’t mean all cooling pads work the same. To see which mattress cooling pads are up to the task of keeping you comfy at night, we put five popular models to the test. In general, the pricier the pad, the more features it has, and—based on our tests—the more comfortable it is.

“Most of the models in our tests had sufficient padding and were quite comfortable to sleep on,” says Bernie Deitrick, an engineer at Consumer Reports who tested the pads.

One perk to using a mattress cooling pad: You don’t have to crank up the AC. “In addition to increasing comfort levels, a bed cooling device can also help reduce energy costs,” Deitrick says. “They can reduce air conditioning costs during hot summer weather because you don’t have to cool your entire room to be comfortable, plus bed coolers use less power than a typical AC unit.” Same goes for your heating costs during the winter.

How We Test Mattress Cooling Pads
To measure how well pads cool and heat, we designed and built a metal device to mimic the human body. We used a lightbulb in each of three parts—a torso and two legs—to maintain a body heat temperature of 98° F. Then we measured how much energy was needed to cool or heat our testing rig with each mattress pad. The better a pad is at either task, the less energy is required.

For each one, we noted whether it has a preheating and precooling function. And for comfort, we looked for built-in padding and assessed whether we could feel any water tubes or other mechanisms in the pad when we used them.
