Spacer bumpers for Slim Edge aren't large enough.
I have a PVC toilet seat that is concave where it meets the toilet, rather than the usual flat surface on the bottom of the seat.
As such, the spacing bumpers, (dampers?), included with the Slim Edge aren't nearly long enough to support the seat when it is down.
Do you have any suggestions, or available parts that would correct this problem? I am concerned that the seat itself will be damaged if the extra support isn't available.
Thank you in advance- Michael Messmer
