here is what I had posted
My opinion is to keep it for awhile and see how it goes with your wifes back. Wendy also has serious back problems and what we are going to do is I am going to make a back rest and do a gel insert for her seat. You remove the seat ... then mark the cover placement....remove the cover , carefully......measure and cut the gel to the area you want....cut the foam about .5" deeper than the gel using electric bread knife and cutting just small pieces at a time to make it easier to control depth.......sand the area smooth with something like a die grinder and small surface prep pad.....glue gel in......fill remaining hole with some memory foam (optional but worth it).....again sand smooth...replace cover.

I have actual instructions in a Word doc. and pictures to show the process. If you want I can Email them to you. I found the memory foam and gel on Ebay cheap.
