End all discussion about who left the toilet seat up with Pressalit's AutoClose. The seat is equipped with a built-in infrared sensor, which recognizes whether a user is present or not. As long as the sensor registers a user, the cover will stay open and once the user has moved out of proximity, it will close. AutoClose is also equipped with soft close to eliminate any slamming toilet seats. As a minimum, the cover will always stay open for 1.5 minutes and the sensor will function regardless of the amount of light in the room.
