Before removing the leather from the cushions preparatory to installing the heater pads, I wanted to make sure it was soft and supple, so I hit it first with Chemical Guy's leather cleaner, followed by two applications of conditioner. The leather looked pretty good before but the difference is noticeable. Have a look at the bottom cover. (The leather has been detached from the the rigid plastic seat form underneath the foam, which is why it looks somewhat loose.)
