Several years ago, I picked up the front and rear seats from an '84 Buick GN that had the Lear Seigler seat option. The car was badly rusted, and the owner was parting it out. The front bucket seats had adjustable side bolsters on both the seatbacks and seat bottoms, and the seat bottoms had an adjustable knee bolster. The upholstery was a combination of gray leather on the outer part of the seats with silver cloth inserts in the middle of the seats. The front seatbacks had the Buick "6" logo stitched into them. The rear seat is much more contoured than a standard G body rear seat, with 2 contoured seat areas in it. I was going to use both the front & rear Lear seats in my Monte, but the front seats weren't comfortable for someone that's my height (6' 2"). The seat bottoms aren't long enough for my legs, and if I tried to adjust the knee bolster, it just started cutting off the circulation in my upper legs. I sold the front seats to a local turbo Buick owner. I kept the rear seat, had it re-upholstered, and installed it in my Monte. It looks much nicer than the original seat.
