purchased a F250 extended cab (not crew cab) 2000yr. recently. and looking for seat covers for it as well. the center council / seat is what did it over for me. wanting any were from $150 to $250 custom made. and nothing pre fab, ((aka cheap 10 to 30 bucks at local walmart / auto stores)).
when i see a design / color i like cheapo's. will be grabbing them just for the 2 front bucket seats, and forget about the center council / seat. and not worry about the rear seats
the websites i did come across. that were selling the $150 to $250 on up covers. were giving a full cover for center council plus lid itself on the council. the websites were normally stating customized seats for the truck. vs some pre-fab doing.

many years ago for the 1997 S10 blazer, looking for seat covers. and i do remember returning a couple of them (cheapo's) mainly due to the straps were complete junk, and would not allow the cover to properly tighten up on the bucket seats. i would slide my rear end in , catch the cover, and end up seating on a un-comfortable wadded up seat cover. hence returning them.
ended going with some stretch fabric on the back. (not a strap, but full back stretchy fabric) and then a couple straps approx 2" wide, for the bottom of the seat. for a nice tight fit. the straps for bottom were not stretchy, but more of a rope material that would not give out over time. it was a bit of a pain getting the straps nice and tight, and knotted correctly, but after that, i completely forgot about it. till i went looking for another set of seat covers for the F250.

for me seat covers a requirment. mainly due to dogs + lake + mud = nasty smelling puppies, and mud tracks.
for myself. mud + boots up to middle of lower leg or higher + smeared mess of mud across boots = nasty mess sliding in/out.
for myself. having to roll in the dirt, grass, mud to fix something / deal with something, and hoping back into vehicle.
seat covers = cheap insurance.
