Many of us here have experience customizing/making amendments to other vehicles, and I thought I would ask if you have had any experiences trying to improve a driver seat cushion for someone who has bad back, leg pain..etc. My spouse had a car accident a couple of years ago and is left with some pain, but it is especially severe after about 30 minutes of driving her Subaru. With careful arranging of pillows, other padding, she can tolerate a short drive, but I wonder if anyone here has found a seat cushion material that has helped in a similar circumstance. Recaro builds many custom seats, but there is no distributor near here to try one on so to speak. Would be interested in surgery to her Subaru seat, rather than her back. Comments? Thanks, Mike
