Re: Howto: Adding more padding to front seats

If I understand correctly, the best way to do this fix is to place, at a minimum, hard, closed-cell foam underneath the existing foam and directly on top of the springs. If more softness is desired, then a second layer of soft foam, between the hard foam and the OEM foam piece, is what's needed. Correct? That would not affect the seat heater or the fabric itself. It also shouldn't affect the passenger side weight sensor...?

Hi Tttait, Can I ask where you got the closed cell tough foam base layer, or at least the details about this layer so I can find my own? I like your design and I want to make sure I get similar stuff; and I know, it's my responsibility, not anyone else's. Do you have any pictures of your formed foam layers?

I already have the details about buying the HR33 foam, so all that's left is the tougher base layer.

Also, has anyone seen how to open the seat back?

I have owned this car since December 2016. With all this info about the seat foam improvements, if GM does nothing to help us in the next ~60 days, I will need to make the adjustments myself since it does not seem to hard to do. (and I am not paying some shop $400 per seat to insert 10 bucks worth of foam)

I swung by House of Foam in Palo Alto yesterday and bought some scraps of high density firm foam - enough to do probably 10 Bolt seats - for a whopping $5.
Today after work I slipped two 1" thick strips in under the existing foam per the awesomely helpful video and it made all the difference in the world. Took maybe 5 minutes. :mrgreen:

Not only does if help with the left leg, but because my ass is moved up a good inch, that annoying bar that hit my right lat below the shoulder blade is now lower and no issue now.

Now the car is perfect!

Unfortunately the closed cell I used was laying around the office, something was shipped to us with it.

Its pictured in the thread about the media campaign to recall the seats. The key quality is that it's tough, I don't think I could tear it with my hands, but it cuts easily. I think it's a polyethylene foam.

When you do the passenger seat it will technically affect the seat sensor. I have not seen any change in its performance, but it does sit right on top of the sensor.

So, is it necessary to remove the front clips, if you only add foam at the back?

They guy at House of Foam was really nice. Thanks for the tip!

Hi.......you mentioned "if GM does nothing to help us in the next 60 days.....". Just wondering, are you thinking or do you have knowledge that GM may actually take action to resolve this seat problem? Or is there any actual movement on this issue from GM? I don't have a Bolt "yet", but I visited a Chevy dealer earlier this week to see the Bolt and I felt the same seat problem described in this thread and others, especially the issue with hitting my left thigh on the plastic base when exiting the vehicle, very uncomfortable. If it wasn't for this seat problem, I'd be driving home a new Bolt today. :-/

Tips for adding the foam:

Did this myself the other day and it worked great, but a few things to make it easier.

1) unbolt the seat to get access. Makes it much easier to access the clips & see what you're doing. You can also reach underneath to help fit the foam where you want as well. Don't need to fully remove if you don't want to unclip the harness to the seat. You'll need a torx 50 bit.

2) retaining clips: they are more designed to slide off to the sides, not to pull & stretch the fabric to get them off. Just slide the clips off the frame to the side & it'd very easy to get them on & off.

3) you need less foam thank you think. Only used a little to put on the edges to buffer from the plastic frame. Got my foam from "The Foam Shop" here in Vancouver. They had some closed cell dense foam.

So my seat was uncomfortable before I took it into repair the issue shown in this thread.

viewtopic.php?f=10&t=6193&p=19714

I got my car back yesterday, and it is clear the entire fabric cover w/seat was replaced (back and bottom), but the seat itself was not replaced, and that is OK.

The issue I have now is my seat is even stiffer and more uncomfortable than the one I had. I will be accelerating my project to insert foam into the seat bottom.

CAN SOMEONE PLEASE upload a video of how to get into the seat back?

Thanks GM, I am beginning to hate having purchased this car.
