Operating Instructions
Quiet-Close Functionality
The Hibbent toilet seat is equipped with a soft-close mechanism for both the seat and the cover. To close, simply push the seat or cover down gently. The mechanism will engage, allowing it to close slowly and quietly without slamming. This feature prevents noise and protects fingers from pinching.

One-Click Quick Release
For easy cleaning, the toilet seat can be quickly removed from its hinges using the one-click release button located on the side of the seat.
- Locate Button: Find the circular button on the side of the toilet seat, near the hinge.
- Press and Lift: Press the button firmly and lift the entire toilet seat straight up from the hinges.
- Re-attach: To re-attach, align the seat's hinges with the posts on the toilet bowl and press down until it clicks securely into place.

Maintenance & Cleaning
Regular cleaning will ensure the longevity and hygiene of your Hibbent toilet seat. The quick-release feature makes this process simple and thorough.
- Daily Cleaning: Use a soft cloth or sponge with mild soap and water to wipe down the seat and cover.
- Deep Cleaning: Utilize the one-click quick release to remove the seat. Clean the seat, cover, and the area around the mounting posts on the toilet bowl. This allows access to hard-to-reach areas where grime can accumulate.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, strong acids, or alkaline detergents, as these can damage the polypropylene material and finish.
- Drying: Always dry the seat and hinges thoroughly after cleaning to prevent water spots and maintain appearance.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Toilet seat loosens or shifts. | Mounting bolts are not tightened sufficiently. | Re-tighten the mounting bolts. Ensure the non-slip pads are correctly positioned. |
| Soft-close mechanism not working properly. | Mechanism may be obstructed or damaged. | Ensure no debris is obstructing the hinges. If damaged, contact customer support. |
| Seat does not fit the toilet bowl. | Incorrect toilet seat shape/size purchased. | Verify your toilet bowl is an elongated shape and matches the 18.5'' dimensions. This seat is not compatible with round or RV toilets. |
| Seat falls slowly when lifted to 90 degrees. | The toilet tank design may not allow the seat to rest at a full 90-degree angle. | Adjust the seat's position using the adjustable hinges to increase the distance between the seat and the toilet tank. This will allow the seat to rest at an angle less than 90 degrees, preventing it from falling. |
