    seat cushion transplant

    I know people have done this but I don't recall seeing any details of how it to do it.

    Re: seat cushion transplant

    You mean swap seats? After considering swapping the two front seats (because each wears more on the outer edge), I realized that only the driver seat needed attention, and the best candidate for that is the one directly behind (if the second row has individual chairs rather than a bench). Because that seat has no direct access from outside, it is in great condition to replace the driver seat.

    Re: seat cushion transplant

    I was referring to switching the butt cushion in the seat, which people have reported doing. But I don't know how.

    I prefer the idea of replacing the entire seat. But when I've mentioned that in the past people acted like it wasn't possible. After pulling both front seats out of my 93 parts van and examining the undersides, I could not find any reason why a switch from one side to the other or to my 97 couldn't be done. However, those aren't in great condition so they aren't transplant candidates.

    I have two rear captains chairs from my 95 that would be ideal to swap in as a new drivers seat for my 97, but they are buried under stuff and I haven't examined the bottoms. Whether the swivel can be removed leaving me with something I can bolt the 97's driver seat rails onto remains to be seen. Seat belt is another possible problem.

    But cushion transplant would still be a possibility, if I could figure out how its done.

    In this thread, I put a "poster"-style photo and description of what to do for a DIY seat full disassembly (I have dozens of other photos and a higher-res version as well I could post.) The executive summary is that a car-upholstery place can rebuild a section or totally replace your existing seat foam for not much money if that's all that's brought to them. Like a lot of other Previa stuff, there's money to be saved if you put in the labor yourself to dis-and re-assemble the seats to get to that cushion, and if you're leaving the seat back alone, there isn't much to it - all the complex stuff is involved with the seat back. It wouldn't hurt to get a quote to see what it would cost to have it done - maybe you could even get an in-the-ballpark estimate by emailing a photo.

    Re: seat cushion transplant

    For the 1991-1993 there's four 12 mm bolts that hold the metal chassis that the foam sits inside of. It's very easy to see the four bolts once the seat is out and you can look underneath. These metal chassis are virtually identical and therefore interchangeable with the front seats.

    I have replaced my driver's seat with a rear captain chair. The foam is in excellent shape because as mentioned there's no real wear on the left out edge of the seat cushion, since there's no access/exit on that side of the rear passenger compartment.

    As for the newer 1994+ and 1996, 1997 seats? I'm not sure how interchangeable the seat components are. I would imagine that the seat frame is indeed the same, but I am not certain.
