Hi,

O.K. I should lose weight and keep the movements to a minimum (..err...don't
shuffle my bum around...) but still the seat insists on sliding sideways.

It is a standard fitting - round brass(ish) plate at the top, plasic washer,
stud which goes down through the (large) hole in the porcelain (no, not the
largest one, just large in relation to the stud size, oh..) and
plastic/nylon nut underneath.

As far as I can tell the only thing holding the seat steady is the friction
between the nylon washer (above) the nylon nut (below) and the shiny
porcelain.

Does anyone have any tricks to make this arrangement more stable?

I am even considering trying to pack the holes out with plastic pipe and
silicone sealant but this is a last resort.

TIA
Dave R
