The vibrating thing drives me nuts. I can feel the edge of it around my back pocket like you said. A lot of people like firm seats, it is subjective, but these are, in my opinion, ridiculously firm. I dont like the bolsters on the cushion either, they are rock hard and I think they are what are causing my feet to start going numb after a while. Now I drive a lot daily, minimum of about 160 miles up to a out 300. If I didnt have to drive that much I could probably tolerate it, but as it is, at the end of the day my butt hurts and my toes are numb by the time I get home. If I try to change my position on the seat to get more comfortable, then I'm dealing with the vibrating mechanism poking at me more or the bolsters digging into my legs more. They really are, to me, the most uncomfortable seats I've had in the dozen or so vehicles I've owned. Sent from my SM-N960U using Tapatalk
