C1: Turn Any Seat Into an Active Air Conditioning

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.

The Cushion That Regulates Your Body Temperature

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.

Active Semiconductor Cooling

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.

Tested by Angel Users

We don't just build for you; we build with you.Before our public launch, we shipped a limited batch of prototypes to a select group of early adopters. We asked for their brutal honesty to ensure C1 performs in the real world. Here is the unfiltered feedback from the very first users.

Finally, no more swamp ass

Mark T.( Financial Analyst, 48): I work in finance and sit for 10+ hours a day. I used to get so hot and uncomfortable by the afternoon, no matter what chair I used. The active cooling on C1 is legitimate—it keeps me dry and focused all day. It’s not just a cushion; it’s climate control for my desk.

A lifesaver for my butt

Sarah L. (IT Consultant, 58):After losing my sagittal balance, sitting became painful and nearly impossible. I’ve tried every foam cushion out there, but C1 is different. The firm support combined with the deep heat therapy actually lets me sit through meetings again without pain. It feels like a medical device.

The upgrade my setup needed

Jason W. (Software Engineer, 29):I spend all day coding and usually love backing new tech. The concept of active thermal control sounded cool, but using it is a game changer. Being able to switch from cooling to heating with a button press is genius. Definitely worth the investment for anyone who lives at their desk.
