How Do I Remove The Back Seat On 2005 Saloon?

[dark andrew]

I guess the topic title kind of gives it away but does anyone know how to remove the back seat on a 2005 Avensis Saloon? I think there may be something down behind the seat rolling about but I can't get to it because unlike the 5 door version, the back seat on the 4 door does not fold forward. It feels like there are a couple of clips under the seat and it slides forward but there also seems to be a bolt (or two) that I can't find.

Cheers

Andy.
