How difficult to replace seat cover, pad?

[yellowbenz]

For those that have done this task, did you regret it or would you do it again? I know I'll probably need a hogring pliers. I need to replace the seat cover on the driver's back and R/R the seat pad. The thing settles so low that the plastic covers on the side bend outward and squeak horribly.

Thanks
