Yesterday, I took my better half out for a 1.5+ hour drive - the longest stretch either of us has been in the car. Granted most of it was slow and some parts were sitting in traffic, and a chunk was stopped talking on the phone (too loud for a real call), we sat in the car the whole time. At about the hour mark, my lower back and hers were aching. I couldn't seem to adjust the seats to get to a comfortable spot, and neither could she. We've both been out in the McLaren 12C for as long or longer, and it rides great (softer I think than the H in Strada vs. 12C Normal mode) and is very comfortable for what it is. No back aches there. So this was unexpected and disappointing.

I'm chalking it up to harder seats and perhaps crappier ergonomics (aka not as good a seat design).

Are we alone in experiencing this? I'm not asking how to fix it because somebody will say "buy new seats".
