About 5% of toilets/toilet seats have a propriety design and don't lay flat after installation, but there's a fix!
If your toilet seat does not lay flat after adding Whisper take the toilet seat off, add one of the included spacers on top of each mounting bracket, place your toilet seat back on top, and rethread the seat bolts through everything. Add additional spacers if needed.
In the unlikely case, your toilet seat still has a small gap (after adding the spacers) you may require seat bumpers available from your local hardware store.
If your order did not include spacers or you are still having issues click the text link "Submit a request" at the top or bottom of this page, describe your situation, include a few pictures highlighting your situation including the underside of your toilet seat and we will help you as fast as possible!
