not all THAT easy.... the clearance to the bolts that hold the seats in place can be a bit of a PITA to get at. And if you're putting the seats back in it can be even worse, IMO. The tracks that the seats slide on tend to fall apart when not mounted to both the seats and the car.
If you just want to lube the tracks and don't want to pull the seats, a can of white lithium greese spray (with spray straw!) ought to do the trick. Spray what you can reach first, move the seat get the back (or front if the back was accessible). Of course, don't forget the drop cloth!
