CES 2025 is nearing a close, and I couldnt be more excited. Not because I dislike the show floor or meeting face-to-face with people I usually only see online, but because Ive been spending the week in a hotel room with a broken heater. Thats why, when I got to try Razers concept heating and cooling gaming chair today, I was just about ready to stage a heist.Dubbed Project Arielle, the chair isnt confirmed for market yet, instead simply demonstrating an idea Razer is considering. But its an idea I fully support. Using the companys existing Fujin Pro chair as a base, Project Arielle includes a heater and a bladeless fan, turning its mesh back into a temperature control system.

Your butt and arms dont get any climate control, at least for now, but it still felt like a literal breath of fresh air.I was a bit skeptical going in, unsure if the Arielle was really going to be much different from sitting a few feet away from a fan. But the breath of cool air on the nape of my neck was undeniably refreshing after walking around the crowded show floor.For my money, though, I preferred the heating, which plays to the strengths of a mesh back by keeping your back warm without getting it sweaty. It's a little less innovative than the cooling mode, but while heated gaming chairs do exist right now, they rarely have as much coverage as the Arielle, and often use materials that can get stuffy after a while.According to Razer, the chairs heater can warm you up to about 86 degrees Fahrenheit, while its fan can reduce your perceived temperature by nine degrees. Why perceived temperature and not actual temperature? Well, if a fan is blowing right on your neck, you might feel a bit chillier than a thermometer would indicate.

Theres also orange lighting to indicate when the device is warming and blue for when its cooling, but those are the only colors it can show for now.Anyway, Im about to go bury myself under some blankets, waiting for the day that this thing comes out for real. Last years Razer concept, Project Esther, did eventually make its way to market as the Razer Freyja, so its not out of the question.
