Bobber Question

Not sure where to place this topic as there is no section specifically for the Bobber.

My question concerns the seat. Can anyone please confirm that the seat structure consists of the padded top piece that is attached to (but can be removed from and swapped etc) a hard base/pan that is then attached by some sort of metal bracket (adjustable I believe) to the chassis of the bike.

Is that how it is?

 

Thanks.
