Houston we have a go!
this is the teaser, but I had to start here first to make sure I could actually put the heating pads in. Now that I know that I can, it’s gonna be pretty straightforward from here. .
it is definitely upholstery and there is about a 1/4 inch light foam stitched into the upholstery on the underside. I am able to slip my whole arm up to the top so getting the pad in there should be not much trouble. Coincidentally, the width of the pad is identical to the width of my opening at the bottom of the seat. This is as far as I’m gonna have to open it up..
Gonna be a warm day tater!!😎
