I've had an RX450H for about 6 weeks. The seats are the most uncomfortable I've ever experienced. My most recent ride was a Nissan Murano, with the most comfortable seats ever. Previously had an ES350 that did not experience this problem. I have memory gel foam cushions that are not helping. My spouse has some heft, whereas I am very thin. Doesn't matter, neither of us can sit on these seats for more than a short trip. I'll be anxious to learn if anyone should find a solution to the discomfort. I'm pretty angry that I've spent over 50K for a car that I can't stand being in.
