I need to add in about half of inch of foam in my front seats. How difficult of a job is that? Does the seat need to be completely removed or is there a way where the seat covers come out? Thanks

You probably will need to get a cushion that sits on top of the present seat. I doubt there would be any room to fit more foam under the factory seat upholstery.

You could hide it with a seat cover that sits over the seat. I got these at Amazon for $35 and they match the Parchment leather very well and look great.

Black Panther Car Seat Cover,Breathable Universal PU Front Car Seat Protector,Non-Wrapped Bottom with Backrest (1PC- Beige) There are several other colors including black and gray.

Thanks I'll check those out. Do they provide any cushioning or some extra thigh support.

Not much cushioning, I got them to protect the crappy leather. They cover the entire seat bottom but only the center of the upper back.
If you search around Amazon or Auto Anything I am sure you can find padded seat cushions in many styles and colors. If you just want a padded seat cushion like the kind that fits any chair, there are many of them in many materials from foam to gel to memory foam. I even saw some at Costco that would cover the entire seat bottom.
