The paint on the forward side of the toilet seat has the paint wearing off, quickly! the paint seams soft and can be rubbed right off What would be eating away the paint. It is a fairly new seat because we recently replaced the toilet.

some of these have bolts under seat...you turn seat to left or right by grabbing while in closed position...this will release the seat from the holding bolts...then tighten the bolts....then reset the seat on bolts then lock down by doing the opposite as you took off...

The cams are worn out inside of seat or it may be to lose you have to tighten up the seat if there is any adjustments if not it is worn out replace toilet seat.

Please can you send me missing parts C right side. As there not in the installation kit pls Also don't close toilet seat. Carol

You need to replace or clean the 1150464 HINGE KIT http://www.kohlerserviceparts.kohler.com/AccessoriesInformation.aspx?ServicePartID=5563b058e2e042868c7a19398797ecd6

Hi,
Right behind the bowl on the underside there is a nut on either side that holds the seat on...tighten those nuts and it will tighten down the seat...

No there is no fix, these things rely on friction for the soft close. You will need to replace it.

Grohe does not make toilets. look inside the tank for manufacturer and model number it sounds like a one piece toilet and the seat bolt nuts are in the tank feel around for them.Grohe only makes handles for toilets to match their faucet finishes

If tank was too far forward it would be leaking you need to use a Kohler seat with that toilet

Each soft close 'Barrel' is handed - one left - one right. (One is grey - the other white).

Most soft close errors occur because the seat hinges come loose. When this happen, the barrels slightly pull-out of the seat. (There are silver discs on the barrels - These should be tight against the seat).

Once the barrels become loose the first thing that happens is the top cover won't soft close - but the seat still does.

To rectify - puch both barrels tighly into fitting and tighten the hinges. (See below).

To tighen the seat hinges you need to get a flat headed screwdriver underneath the chrome round hinge cover - and 'flick off'. Underneath is a X head screw which id also hexagonal. You can either tighen both by spanner - or screw driver. (sometimes these can be tricky - but it will come off).

If both cover AND seat do not soft close AND the barrel silver discs are firmly located against the seat - the barrel has probably broken.

If so - spare parts can be obtained here:
