Obviously this is a used item, it was a 'soft close' seat but the mechanism doesn't work so you have to close it manually.
Fittings and sample instructions are included for a toilet where the fitting bolts are visible below the sides of the toilet,
not the new fangled type with just two holes in the top.
In Broadstone, will end up in the Poole Tip 'hard plastics' skip if no-one wants it.
