Seats bottoming out. PAIN (Page 1/2)
robmox MAY 28, 11:30 PM
I’ve made posts in Technical Discussion trying to get to the root of my problem, but it wasn’t until my girlfriend joined me in my Fiero for the first time that it occurred to me, my seats are totally ****ed.

For those who haven’t seen it, I’ll put all the info in one place. I bought my Fiero about 320 miles from home, and drove it back. By the next day, my tailbone was so sore that I couldn’t sit. My tailbone had been sore prior to this trip, so I thought my poor flexibility was partly to blame. And, my shot suspension combined with Nashville’s horrid roads was another factor.

But, I’d been using an added cushion in my Fiero, to protect my injured bottom, and the injury had been healing, so today I went without the cushion, and as soon as I sat down I felt the pressure directly on my tailbone. Then, my girlfriend sat in the car and felt the same thing in the passenger seat.

So, this evening, I pulled out my driver’s seat. I can press about a 2 inch indentation in my seat with just the strength of my fist. That means I’m already sitting on the floor before I even start driving. And, every bump I drive over is a direct hit to my tailbone.

I have to assume I’m not the first person to experience this. But, I searched these forums and googled, and what I found was that people take the Fiero seats and put them in other cars, because they find them to be comfortable. Well, the Fiero seats are the single most uncomfortable thing I’ve ever sat on, and I’ve taken multiple 11 hour flights. From what I can tell from the service manual, there’s a wire grate imbedded in the foam seat bottom, and I assume mine’s become detached.

While I like the stock Fiero seats looks, I think I have to replace them with Sunfire seats. If only for my butt.

I don't think I've ever read a post here about anyone's butt hitting the floor, and I've been here a long time.

If you don't get an answer from a fellow sufferer, what about searching the Forum for other Nashville members? You can send them all a PM and arrange a meet-up with whoever responds and try their seats out, just to confirm that regular Fiero seats would still work for you. It does sound like your seats are toast.

At least in the short term, I’m gonna hold on to my stock Fiero seats and see if I can revive them. If I can, I’ll put some MrMikes on them.

The seat bottom is a steel frame with an opening in the middle- then foam was bonded to it- this worked for 15-20 years just fine. But after a while the foam starts to sag in the middle. I realized this after taking the seat out to be recovered with a passenger-seat cover. I asked the upholsterer if he could do anything about it. He installed webbing straps across the bottom to support the foam in its original shape. Still good after (at least) 10 years.

So theoretically, I could just put some webbing across the bottom to hold the foam up?

I was thinking about this. At 240 lbs, I can’t imagine I’m the heaviest person here. And, the bottom foam of the Fiero seats basically sits on the floor. As far as I can tell, there are springs embedded somewhere in the foam, but the thing supporting the weight from the bottom is a piece of fabric so thin that it’s transparent, and every pic I’ve seen of it, it’s broken.

The one thing I can’t figure out. How are both the drivers and passengers seats broken like that?

I’m starting to think I’ll try and repair the seats now instead of getting sunfire seats. At worst, I’ll put nylon webbing on the underside akin to a folding lawn chair. I can just rivet it in.

That’s funny, because I actually emailed MrMike about this and he didn’t mention. I’ll give this a shot.
