I made the MISTAKE of searching long & hard for REPLACEMENT seat cushions. Very SS @ $400 with shipping. I since went to a local 'custom' shop that also offers auto upholstery repair & they quoted $150 max. to repair the only panel that was worn. Because the drivers back cushion was so difficult to find, I bought 1yd of the replacement fabric for any future 'panel' repairs for $70. I would suggest the same.
