How do I remove the driver seat cover?

[cashville]

I'd like to remove the lower driver seat cover, because on the door side the stitches have broken, so I'll have to remove the seat cover to have the rest of the stitches removed, and then redone again on a sewing machine so it looks like new.

Any tips on how to remove the lower driver seat cover easily? That is the only part of all the seats that need sewing.
