- Easier to install in confined spaces
3. Quick-Release Fixing
- Enables easy removal for cleaning
- Usually includes a push-button mechanism

Step-by-Step Guide to Fitting a Toilet Seat
Step 1: Remove the Old Toilet Seat

- Locate and unscrew the bolts at the base of the old seat
- Use a wrench to hold the nuts underneath while turning the bolts
- Clean the area thoroughly before fitting the new seat
Step 2: Align the New Seat

- Place the new toilet seat over the holes on the toilet bowl
- Ensure the seat aligns symmetrically with the rim
Step 3: Insert and Tighten the Bolts
- Use the appropriate fixing type (top or bottom)
- Tighten bolts securely, but avoid over-tightening to prevent cracking
Step 4: Test the Seat
- Open and close the seat to check for smooth operation
- Ensure the seat doesn’t wobble or shift
How Dampers Improve Soft-Close Toilet Seats
Dampers are crucial for the performance and durability of modern soft-close toilet seats. These devices use controlled resistance to slow down the closing motion, offering a seamless and silent experience.
Benefits of Using Dampers in Toilet Seats:
- Prevents Noise: No more loud slams, ideal for night-time use
- Reduces Wear and Tear: Extends the lifespan of the toilet seat
- Improves Safety: Minimizes the risk of finger injuries, especially for children
- Enhances User Experience: Creates a luxurious and smooth-close feel
