2006 Escalade ESV Platinum seat replacement cushion, padding

Hello,

I have a 2006 Escalade ESV Platinum, and I am looking for replacement seat cushions/padding for the heated and cooled seats. I am only able to find replacement cushions for non Platinum models that are not compatible with the cooled seats. I was wondering if anyone has found a place that sells the cushions for the cooled seats, or what the difference is? Could I modify the non Platinum cushions to work with the cooled seats? Thanks
