Sorry for bumping a 3 year old post, but I recently bought a 2014 Mazda 3 i grand touring to replace my (rusting) 2001 Protege. It has the power leatherette seats with manual lumbar.
During the test drive everything felt great, but after having driven the car for 3 weeks, I have a really severe, and screaming lower back pain. The pain is right between the top of my tail bone and the curve in the lower middle of my back. It has gotten so sore that I feel it when not sitting in the car as well.
In fact, it has gotten so bad, that I pulled the ad for my old Protege from Craigslist, and have been driving that car to work again, since those seats fit me like a glove. Three days of driving my Protege and my back pain was completely gone. I went back to driving the Mazda 3 (thinking I imagined the back pain), and half way through my morning commute I had shooting pain in my lower back, down my right leg again. I'm so frustrated with this I almost want to cry. I love the Mazda 3, but I just can't stand sitting in it.
So I did some testing with all kinds of pillows and rolled up towels and comparing things between the Mazda 3 and my Protege (the Protege is absolute heaven for me to sit in) and I found the lumbar support in the Mazda 3 is too low and too pronounced, even with the lumbar on the lowest setting. it just does not hit me in the right spot at all.
Because the lumbar is too low, I need to scoot a little forward for it to hit my back properly, which causes my butt to be pushed away from the seat too much, causing the area right above my butt and the small of my back to not be supported by the backrest at all (I can stick a fist in the gap between my back in that area and the seat). The Protege seat on the other hand doesn't have this ridiculous lumbar issue, so I can sit with my butt all the way against the back of the seat, so the seat supports my whole back properly. Which is how a seat should be!
I folded up a bath towel and put it against the bottom of the back rest...And guess what, the seat is almost as comfortable as the Protege. I can sit all the way with my butt against the back rest, with the weird gap now filled in by the towel and the lumbar support hitting me in the proper spot in my back.
It is still not 100% perfect, as the Mazda 3 seat bottom is too flat (and you can't tilt the forward section of the seat upwards like the Protege), but it's a helluvalot better.
At work right now, but will post some pics tonight to show what I mean and how I have the towel.
I am currently still driving my Protege and leaving the Mazda 3 parked, but now that I read through this topic I realized I should maybe also contact an upholstery store to see if they can somehow fill in the bottom of the seat back a little, to make the seat flatter and fit me better.
Now, the headrest is an entirely different issue, but I'm so fed up with this I might just bend them back with some force...If I break the headrest, at least replacements are easy to come by.
Man, Mazda really screwed the pooch on these seats
