I'm really curious - and I don't mean for this to sound snarky, that's not my intent. For all the people who think the seats are uncomfortable in their Explorer, when one thinks about the length of time a person will be sitting in those seats - well, why would you go ahead and purchase the vehicle if you don't like the seats? To me, that just sounds like a no-brainer - don't like the seats, then don't buy the car! I don't believe I'd purchase something as expensive as a car and "hope" that I can find a work-around to the comfort issue. I have severe back issues, I've had 5 back surgeries in 12 years (4 of them in the last 3 alone!) so seat comfort is paramount. I actually buy an SUV solely for the purpose of the seating - the car is taller, the seats sit more upright (unlike my husband's Scion where my butt is within 12" of the road and I pretty much have to just roll out of the car to disembark!!).
Before I bought my Explorer a few months ago, I had a '13 Edge Limited and, to me, the seats of the Edge and Explorer feel identical, just that Explorer is a few inches higher off the ground. The Edge and Explorer are actually almost identical in every way (aside from 3 year age difference and improvements) - same dash set-up, exact same Sync, Nav and Sony sound - the Explorer is just a bit bigger, longer, wider but even with the car width, I still think the seats are the same width, there is just more leg room.
As for the Power Seats and the Lumbar, I've always had to fiddle with the seat settings to get them just right and honestly, it really takes weeks, if not longer, to find what's perfect (thank goodness for Memory Seats!) but the Lumbar, for me, is perfect pumped all the way up. I love the pressure it pushes into my back, since I'm in chronic pain.
So, that brings me back to my original question. For me, with my back issues, seat comfort is paramount and there is no way I'd ever buy a car if the seats weren't comfortable, regardless how much I love the car! As for my husband's Scion, it was bought new in 2006 - and I've ridden in it probably less than 20 times in 11 years, that's how much I hate it - and forget driving it! So why would you spend so much money on something you're not comfortable sitting in for any length of time?
Again, it's just a curiosity question, I'm not being judgmental.
