Hey all, I have a new project that I wanted to get some feedback on.

I have a 2008 4Runner SR5 (4WD) that I am going to be putting some aftermarket seat heaters in. I drive about 100 miles a day to/from work in mostly traffic. When I install the heaters, I was thinking about swapping the cushion foam out with some 4LB memory foam.

My question is this. Has anyone ever done something like this? Is it advisable?

Thanks!

John
