Balance On, the healthcare brand of automotive products company Bullsone, is turning a content creator's offhand idea into reality.

Balance On announced Tuesday that it will serve as an official sponsor of the 2026 ACC Haneul Madang Space-Out Competition, to be held Saturday at the Asia Culture Center in Gwangju.

The sponsorship traces back to a collaboration video in which YouTuber Mimimiminu — playing the role of a new Bullsone employee — tested Balance On products and pitched promotional ideas. One of those ideas was to place Balance On seat cushions on the chairs used by Space-Out Competition participants, letting them experience the product naturally during the event. Balance On developed that suggestion into an actual sponsorship deal.

The Balance On seat cushion has sold more than 1.7 million units since its 2015 launch, earning a following among students and exam-takers who call it a "study cushion" or "exam cushion." The product combines an ergonomic design with BetaGel, a patented material that distributes body pressure across the seat.

The cushion's performance has been validated in testing. Using pressure-distribution measurement equipment at a state-certified research institution, the product was found to reduce pressure on the lower back and hips by up to 76 percent, helping ease the strain of prolonged sitting.

Testing also showed the cushion suppresses cortisol — a stress hormone — by up to six times and improves concentration by 14.3 percent.

To mark the sponsorship, Balance On is running a promotional sale through Thursday on its Balance On Mall and Bullsone Mall online stores, offering the Balance On seat cushion and other key products — including those Mimimiminu personally tested and praised — at discounts of up to 66 percent.

"It is meaningful to bring Mimimiminu's bright idea from the content to life as an actual event," a Balance On official said. "We hope people will experience the comfort of the Balance On seat cushion firsthand at the Space-Out Competition and find it at a reasonable price through the linked sale."

Meanwhile, last month Bullsone — South Korea's top automotive products company — teamed up with Mimimiminu, who has about 1.97 million subscribers, to run a large-scale promotional sale called "Bul.Mi.Se" (Bullsone Mall x Mimimiminu Sale) on its Bullsone Mall platform.
