I actually find the model X seats comfortable. They are supportive and roomy. Try the S man.. its like a tight little can.
I love the X but come on! SO hard and narrow, even for a small female like myself. Please take a cue from Lexus and Mercedes in ergonomics!
I came to the X from a BMW 5 series M-Sport that had sporty seats with great thigh support, and initially felt the MX seats to be extremely uncomfortable - with poor ergonomics for placing the back of my arms on the door edge or the small, recessed arm rest.
As I got to fiddle around with all the thingamabobs for the seat (height, recline, track position, lumbar, headrest) and the steering wheel, I am starting to get comfy in the seats. With the right lumbar support inflation to suit your frame, the seats CAN feel more comfortable. But I feel the ergonomics of the MX driver's seat needs serious redesign. The seat is not comfortable out of the gate, without major fiddling with the controls.
The entire product range needs more adjustability in the seats. The thigh support in particular is deplorable for us tall folk.
Huh. My heated steering wheel, seats, and ventilation system all work just fine. In fact, I mentioned to the wife today that even when set at 21, it sometimes feels too hot due to the warm air in my face. Not sure why yours has problems - do you have range mode in?
Big guy here, just traded my 2014 Model S for a 2016 Model X. For me (big guy), the model S seat was way more comfortable than the X seat. The seats need more adjustments than just lumbar. FYI, I had a 2014 Corvette and the seats in it were very comfortable and they are of course sport seats...
In the X I'm basically spilling out over the seat bottom and seat back and it's not very comfortable. On my S the seats were flatter and seemed wider since they weren't sport style seats...
