Hi, yes I have.
The rear seat comes out in two parts, the base and the back. For the base there are two bolts that must be removed, these are at the bottom of the base on the left and right side and might be covered with a plastic cap. Remove the bolts and then the seat should be able to be pulled upwards and come out. There is some double sided tape that is used to hold the seat in place so you might have to pull hard.
Next there are a number of screws that secure the seat back to the frame which is motorised. These are at the bottom of the seat back and there are two or three I think. Once these have been removed the seat back can be pulled forward. At the top of the seat back there are some pins that slot into guide holes in the frame, you will need to pull the seat towards you first.
