DanTwoLakes If it makes you happy, that's all that counts.

Mojo56 Nice job... my '52 Pontiac also has some pretty weird seating for some reason...way too thick of a seat cushion to be comfortable for me. I might try this when the time comes.

rockable Worked on my seat this weekend. I could not live with the springy original seats but I wanted the seats to look mostly original. With the help of DanTwoLakes, I came up with this solution.

I built a 3/4" plywood base for the bottom and two 1/2" plywood seat backs with brackets to make them mount in the original frames.

I ordered a sheet of 3", 4" and 5" firm foam to try. I ended up liking the 5" foam in the bottom and the 4" in the backs. This will fill out the frame and make the seats look good and sit good. These things are better than my sofa in my house and I have the seat and steering angle to my liking now.

I had to make an adapter that moved the seat back a couple inches and will make a block that will get the inclination like I want it.

The seat frame will still need to be blasted and painted. Then, when I'm ready, I will take it to the upholsterer and let him finish trimming the foam and do the upholstery. I'm pretty happy how this turned out, so far.

rockable That's what I thought. Thanks again!

DanTwoLakes The upholsterer may add some dacron batting to the foam, but that should be insignificant to the end result.

rockable Dan,
I got a block of 3",4" & 5" foam from Rochford. I like the way it sets up with the 5" block as the bottom cushion and the 4" block as the seat back cushion. I have the rake adjusted to where it is very comfortable to me and my 6' 2" frame.

Here is my question. The upholsterer will add additional padding to the foam. Correct? Will this additional padding add any significant changes to my dimensions that I have dialed in? Or will that be mostly insignificant.

Thanks for your help!

DanTwoLakes The seats will definitely be better for long trips with what you plan to do.

Jaer007ll Thanks, Dan. I'm beginning to get the picture. I'm not convinced that even with new springs, the seats would be comfortable on long trips.

DanTwoLakes 61 compression should be fine if it's at least 3" thick. I'd go with 4" if I were you. No, you won't compress the foam much on the seat backs. There you could use 2" and be just fine.

rockable How much will 61compression foam sink with my 210 pound butt planted in it? I am trying to figure out how thick the foam needs to be. I assume the seat backs won't compress much at all. Correct?
02-19-2012 07:52 AM
DanTwoLakes I would stick to all one foam. If you mix them together it would be fine, but it may get pricey.
02-18-2012 07:56 PM
rockable Thanks, Dan. I knew to drill the holes. This was just a pattern to test my idea. Would you recommend laying down a base of stiffer foam and then layering some firm on top of it?

There is an online source here in NC called I'll check them out.

Thanks again.

DanTwoLakes What you are doing will work. They will glue the fabric onto the metal, you won't need tabs. As far as the "incline", which is called pitch in the furniture world, the simplest thing is to angle the base, not the foam, but it can be done either way. Yes, the foam will be glued to the plywood. You should drill some 1" holes through the plywood to let the air escape through the plywood, both on the backs and the seats. Either that, or cut out large rectangles and criss cross the openings with elastic webbing.

If you can't find foam to your satisfaction on the internet, I can get you whatever you want from my supplier and have it drop shipped right to you. One online source for foam is Rochford Supply. CLICK HERE The firmest they have is 61 compression which should work O.K.

rockable Today I tried to figure out a way to use my original frames and pad them up with foam. Please review these pictures and tell me if this will work.

I used some crappy 1/2" Chinese plywood that I had on hand to make a pattern and test my idea. I used some 1" sq. tubing to make the top part that hooks onto the seat back frame and I used another piece to provide the bottom. This piece has two holes drilled and tapped into it so that two 1/4" screws can be installed from the rear with some dress up washers to retain the cushion to the frame.

All of this looks like it will work ok to me but I am NOT an upholsterer. I will take this to someone else to finish. The question that jumps out at me regarding the backs is how will they fasten the fabric to the square tubing. Should I weld on some of those little "shark tooth" looking tabs? Or will they just glue it?

The seat bottom will be cut from 3/4" plywood and should be very straightforward. I am assuming I can build the foam up to provide the incline on the seat bottom. Or should I fabricate something that puts the angle in?

Does anyone have any good sources for ordering the foam to build these seats up? Should I just glue the foam to the plywood?
