The 8 best comforters for every type of sleeper
While everyone's sleeping setups are different, a comforter is a crucial part of any bed. Once you find one that suits you, you'll likely enjoy improved sleep. What makes a great comforter is to some extent a matter of personal preference. Some people want warmth and coziness while others prefer something cool. Weight is also important to consider — I personally like one that has some heft to it, but feather-light designs are equally as popular. Similarly, the material of the outer will dictate how it feels against your skin and how temperature-regulating it is. If you share your bed with pets, you'll want one that's machine-washable or invest in a duvet cover that can be washed. Many of the comforters I tested have been designed to be temperature-regulating, which means you shouldn't get too hot in the middle of the night. Nylon for example is moisture-wicking — if you sweat during the night, the fibers in the nylon draw moisture away from the skin and transport it to the surface of the fabric, where it has space to evaporate. Lyocell (also called tencel) works in a similar way. Another fabric to consider is cotton which helps keep you cool because it's made with a loose weave, allowing heat to dissipate more easily. With all this in mind, I've spent months testing comforters across different budgets and weights to help find the best options for you. How I tested I paid attention to how the fabrics felt against my skin and how the comforter stood up against the marketing claims (did the comforter keep me warm or did its temperature-regulating powers work). Since I wanted to understand how each comforter performed on its own, I didn't use a duvet cover with any of them. In addition to my own experience of the comforters, I also asked my partner for his thoughts. I tend to get cold easily while he overheats easily, so it was valuable to have his perspective. The best comforters for 2025 are:

Astronomers finally figured out how Pluto cools itself
If you purchase an independently reviewed product or service through a link on our website, BGR may receive an affiliate commission. Pluto might be small and distant, but it keeps surprising scientists. After the New Horizons spacecraft zipped past it in 2015, we got our first real look at its icy landscape and unexpectedly active atmosphere. But even with those discoveries, one question lingered in scientists' minds. How does Pluto regulate its temperature with such a strange environment? Well, thanks to new data from the James Webb Space Telescope, researchers say they may have found the answer, and it's pretty wild. Where most planets rely on gases in the atmosphere to regulate their temperatures, researchers believe that Pluto cools itself using haze particles. Today's Top Deals Best deals: Tech, laptops, TVs, and more sales Best Ring Video Doorbell deals Memorial Day security camera deals: Reolink's unbeatable sale has prices from $29.98 See, Pluto's atmosphere is incredibly thin and made mostly of nitrogen, with traces of methane and carbon monoxide. What makes it special isn't just its composition, but the presence of a constant haze. This haze is made up of tiny particles, and if the data from James Webb is correct, it does more than just drift around in the cold. Normally, planetary atmospheres manage temperature through movement and properties of gas molecules, as I mentioned before. But Pluto cools itself differently. As sunlight hits the planet, the haze particles absorb energy and rise. When they cool, they sink again. This up-and-down cycle helps manage the planet's heat, keeping the atmosphere in a delicate balance. No other world cools itself this way, as far as we know. The idea is kind of crazy, but it also isn't unprecedented. Researchers actually proposed it a few years ago, before we had any proof. That's where James Webb comes in. Recent observations focused on Pluto using mid-infrared wavelengths. The telescope detected the exact type of thermal signals that scientists had predicted. The haze in Pluto's atmosphere was indeed radiating heat, just as the theory suggested it would. But these findings tell us more than how Pluto cools itself. They will also force scientists to rethink what's possible for other hazy worlds. Moons like Titan and Triton, for instance, also have nitrogen-heavy atmospheres and thick hazes. They could be managing their heat in similar ways. There's also a deeper link to our own planet. Researchers say Earth's early atmosphere may have looked more like Pluto's, filled with nitrogen and hydrocarbons. By studying how Pluto's haze behaves, researchers might uncover clues about how conditions to support life first formed here on Earth.
