5. Setup and Installation
The Himimi Universal Toilet Seat is designed for simple and quick installation. Please follow these steps:
- Prepare the Toilet Bowl: Ensure the toilet bowl surface where the seat will be installed is clean and dry. Remove any old toilet seat and hardware.
- Insert Expansion Bolts: Place the expansion bolts into the toilet bowl's mounting holes.
- Attach Hinges: Position the hinges over the expansion bolts. The Himimi toilet seat features 360° adjustable hinges, allowing you to rotate them to align perfectly with your toilet's mounting holes (hole spacing 120-216mm).
- Secure Hinges: Insert the screws through the hinges and into the expansion bolts. Tighten the screws until the hinges are firmly secured to the toilet bowl. Do not overtighten.
- Attach Toilet Seat: Align the toilet seat with the secured hinges and press down firmly until it clicks into place. The quick-release mechanism ensures a secure fit.
- Cover Caps: Place the decorative cover caps over the hinge bases for a clean finish.

6. Operating Instructions
The Himimi Universal Toilet Seat is designed for ease of use and comfort.
- Soft Close Function: The toilet seat and lid are equipped with a soft-close mechanism. This feature ensures that the seat and lid close slowly and quietly, preventing slamming and reducing noise. Gently push the seat or lid downwards, and it will close automatically.
- Quick Release for Cleaning: For thorough cleaning, the toilet seat can be easily removed. Locate the two quick-release buttons (often near the hinges) and press them to detach the seat from the mounting posts. Reattach by aligning and pressing down until it clicks.

7. Maintenance
Proper maintenance will ensure the longevity and hygiene of your Himimi Universal Toilet Seat.
- Regular Cleaning: Clean the toilet seat regularly with a soft cloth and mild, non-abrasive soap or a dedicated toilet seat cleaner.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, strong acids, alkalis, or chlorine-based products, as these can damage the antibacterial surface and cause discoloration or corrosion of the hinges.
- Drying: After cleaning, wipe the seat dry with a clean, soft cloth to prevent water spots.
- Hinge Care: Periodically check the tightness of the hinge screws. If they become loose, gently tighten them to ensure stability.
8. Troubleshooting
If you encounter any issues with your Himimi Universal Toilet Seat, please refer to the following common solutions:
- Seat is Loose: Check if the hinge screws are securely tightened. If the seat still feels loose, ensure the expansion bolts are properly seated in the toilet bowl holes and the hinges are correctly aligned.
- Soft Close Not Working: Ensure the hinges are clean and free from debris. If the issue persists, the soft-close mechanism may be worn and require replacement.
- Difficulty Removing Seat: Ensure you are pressing both quick-release buttons simultaneously and firmly. If the seat is new, it might require a bit more force initially.
- Seat Discoloration: This is often caused by using harsh cleaning chemicals. Refer to the maintenance section for recommended cleaning practices.
