Seat removal

trying to get my new track seats fitted and having a nightmare.

Passenger side all done

Drivers side rear 2 bolts are now out with a fight!! Front 2 on drivers side will not come loose. I’m not a feeble bloke. I’ve proper gone for it and they will not come loose!

Doing my head in. Any ideas what else I can try?
 
Assuming they are not rounded use a long extension. One of mine chewed as wasnt straight so had to use a sharp chisel to crack it. They are very soft and damage easily. Just push the soft seat overhang aside
