19 CX-5 GT-R uncomfortable drivers seat fix?

How have others fixed the drivers seat to make it more comfortable. The bolster on the left side makes my thigh numb after anymore than 30min of driving. Never had this happen in any other vehicle I've owned and I'm 46 years old. I bought a memory foam seat cushion which helps a little but not enough. I'm considering taking to an upholster store but I'm concerned that they will ruin the seat or screw up its functions. I know others have had this issue and I would love to know if anyone has found a fix?
