Having a hard time deciding on my next seat, need recommendations

Looking at Sears Elite 80, Knoedler Grand Chief, K&M, etc. The more I look, the more I cannot decide, though I am leaning towards the Knoedler.

There must be a bunch of o/o's that have replaced or upgraded their seats, right? When I spec'd out my 2000 Volvo 770, I got the best seat they offered at the time, though I cannot remember the seat brand. 1.5 million miles later after rotating the driver and passenger seats (identical) a couple of times, I had to replace it and didn't have time to get what I wanted, had to get what was available which ended up being a Seats for about 450. It's kinda OK, certainly better that the one I replaced, as it would stay up at all, but want to get a good seat. 700 to 1200 or so price range.

By the way, when I checked w/Volvo to see if I could buy a new one of the original type, it comes up in their computer as UNAVAILABLE.

Also wondering if anyone has the heat and cool option and if they feel it is worth the money. I had heat on my original seat and really didn't use it much.

 

One of the things I like about the Knoedler, it's not real wide. I'm not real wide, though have a front bumper. It's firmer that the others also.

 

are we talking the Bose I saw prototype of a couple of years ago at MATS? SEVERAL thousand $$$$, ???
