I've removed several seats (not the explorer's yet) and the way I do it is I push the seat all the way back to expose the front bolts (remove them), then move the seat all the way forward to expose the rear bolts (remove them) then keeping the seat in the upright position, lean it back towards the rear to expose the harnesses you need to unplug. Then just lift up and angle/swing it out sideways.
I normally take all my seats out every couple of years to vacuum and shampoo the carpets. With the husky liners, I haven't had a need to do it yet as protection is incredible.
Good luck.
