I was thinking the same thing, and I'd probably insert some memory foam if I remove the seat springs altogether. Here's what I'd buy: just some Overstock.com memory foam pillows:

When i drive like a deek, i just slide around. lol. i wont really know how it is until spring(ish) because i am most likely going to be in active duty with the Air Force.
Thanks for the great ideas!!

Try unzipping the back seat cover a bit and stuffing some strips of foam on top of the seat bolster. I got a lot more lateral support for my skinny backside.

Maybe you could use slidewaysteve's bar idea and attach your "dampers" to it.

I would like to try this, as it's not quite as permanent as cutting the springs.
However, I can't really tell, but it looks like you've drilled and screwed your added bars to the existing cross bars (are those bolts at the front)?


Is it important that I secure the added bars? Or do you just have it zip tied to the springs and held by tension?

[SWortham]

What about removing the springs from the seat and in their place install some firm, high resilient foam that simply sits on top of those bars? That way you'd get more cushion, and no more bounce.

Perhaps the "Firm" foam from this site would do...
Custom molded flexible high resilient and viscoelastic (memory) polyurethane foam - Bryn Hill Industries

I suppose some sort of platform for the foam to sit on may be needed.

Wouldn't only using the two outside bars achieve the same effect? In essence, all you are doing is moving the mounting point of the bars lower.

Plus, with that setup, I wonder if you simply sink down until you hit the black bars, at which point you weight is pushing them downwards, making them lose contact with the seats two polished bars.

That's where my question derived from. I assume that he's drilled into the polished bars and attached those bolts to make sure that they maintain contact.

If that was his reason, he failed to follow through since the rear is loose.

I have one (Not a mattress but a mattress pad, to go over a regular mattress) and my cat pissed on it. I refuse to use it but it's just hanging out in my closet. Maybe ill try and use a piece of it.

If it is good enough for NASA, it is good enough for us I believe I know where I can find some of it. Call you tomorrow afternoon.

I just did this progressively over the past few days. On the lower portion of the seat I removed the middle of the 3 springs, then ziptied the rear one to the solid metal bar. The result is fantastic, and I am definetly sitting lower.

On the back portion of the seat I removed all of the springs except the smaller upper one. The springs simply pop out with force, so no cutting is necessary. Overall the seating position feels WAY better and finally holds me in good.

When I first started removing the springs, I removed the middle lower one first. Drove to work and it felt great. I felt it could have improved more, and removed the remainder of the aforementioned springs. I'll drive it to work again tommorow and see how it feels, moreover, test sitting right now feels darn good. Thanks to those that hypothesized this.

[wrxtc]

I have one of these sitting on top of my seat, huge improvement.

[Alex]

I will try the spring deal. I am still thinking up a way to get additional foam in there w/o distorting the original seat pattern, etc.

[mgsm666]

^^ maybe inserting some of that foam above the springs, once they are pulled down? Just have to find a cheaper place to get nice memory-foam.

for the skinny guys, use some pipe insulation foam in a strip on the right and left rib bolster to make the seats narrower to hold better.
I also pulled the lower and back springs outwards to let me sit deeper, but I still get bobble

I pulled the springs and stretched the crap out of them as well.
It made a difference but I do still get some bobble.

What's improved is my reaction to large gaping holes on freeways. Before, I would actually put my right foot against the foot rest and brace for the impact consequent liftoff like I was in a rollercoaster. Now I just sort of do a quick breath and the car takes it. I still move a bit but not that bad.


Sadly, pulling the lower springs makes you sit lower but not by much.
Pulling the back springs really made a difference.
MAKE SURE you pull the back springs evenly and test them out before driving off.
I pulled mine a tad unevenly at first and then I drove off for work. I had the meanest pain in my back after sitting crooked for a good 45 minutes.

Since the airbag is in the top half, would it be possible to make a seatcover with the foam inside just for the lower portion of the seat wrapped in a similar material, like a pullover for your ass?
Just a thought.....
