C3-150 is a bidet offering both internal and external comfort. Not only is the seat comfortable, but it also offers easier and more comfortable elimination. The design team spent much effort on the seat to improve the toilet experience. After many ergonomics tests, a well-designed seat surface effectively eliminates pressure points produced from sitting on it. While sitting upright, the user’s back is naturally tilted forwards and the thighs are slightly raised, resulting in optimum toilet posture for easier elimination. A better-angled inclined side panel offers a better user experience. The minimalist gaps design makes it easy to clean.
