67 Catalina wagon rear seat

[Petegto]

Can someone tell me how to remove the top cushion in the rear seat on my 67 Catalina Wagon?
I tried everything I could to remove from the frame and the folded metal that is attached..
Photos be great or what needs to come apart to rel the top cushion.
Thank you

When you say rear seat do you mean second or third row?
