Say goodbye to swamp ass. C1 is the only cushion that actively cools you down to 75°F. No gels, no gimmicks—just powerful semiconductor cooling. Whether it’s freezing cold or therapeutic heat, you control your comfort with the touch of a button.
Meet C1, the first active AC cushion. Unlike passive gels, it uses semiconductor tech to cool to 75°F (24°C) or heat to 108°F (42°C). Eliminate seat sweat, soothe pain, and upgrade any chair into a premium climate-controlled station.
Fans just blow hot air around. C1 is different. It uses a real cooling engine to actively freeze heat—just like your fridge or AC unit. It pulls warmth away from your body and pushes it out the back, keeping your seat icy cool even in a hot room.
