Razer’s Project Arielle gaming chair warms and cools your butt year-round

It’s not enough to just expect your gaming chair to keep you cool during hot summer days anymore. No, it should also keep you warm when your bones start frosting over in the winter.

If that sounds like a pipe dream, it’s not. Razer’s Project Arielle, announced at CES 2025 in Las Vegas this week, is one such chair, capable of turning down the heat on your backside or warming your buns up when they get a little icy. That description is probably a bit tongue in cheek, but Project Arielle is a serious piece of gaming hardware.

It’s based on the Razer Fujin Pro, one of Razer’s most comfortable thermally engineered gaming chairs. But unlike the Razer Fujin Pro, which relies mostly on breathable thermoplastic elastomer and polymer blended fabrics to keep you cool, Project Arielle incorporates an integrated bladeless fan system that can deliver continuous full-bodied airflow to your full body as you sit.

Cooling comfort can be personalized by adjusting to one of three fan speeds, and that cooling effect is fairly decent, too, we’re told.

In fact, Razer claims Project Arielle can successfully dissipate heat to provide between 2 to 5 degrees Celsius (3.6 to 9 degrees Fahrenheit) of perceived cooling. We’re not quite sure what the difference is between perceived cooling versus real cooling, but it sounds like the difference between sweating like a pig and being downright comfortable.

The on-demand heating provided by the chair is delivered by a built-in heating system that incorporates energy-efficient PTC heaters. They can provide warm air up to 30 degrees Celsius (86 degrees Fahrenheit), or enough to keep you toasty even when the mercury drops.

But the best thing about the chair is you don’t have to get up or stop gaming to get it working. You can simply select your desired temperature while sitting via a convenient control panel. Project Arielle’s price and availability are yet to be announced by Razer.
