    Here’s my 34 coupe seat I built up from a stock seat pan,first I made new plywood back, base, and carriage boards
    I used furniture webbing on the base 48AFA3E3-E717-4954-9DBA-DE3FD2DCBCC2.png 15FE9592-51DC-4B1D-99B4-8E362462348D.png 9AA01FF5-4989-4A68-8FC9-1400798898F4.png

    Then I used a bandsaw to cut new cushions from 6” dense foam, adding a 1/2” dense foam horse shoe bolster 1AB8973B-3D99-4E81-8E57-698A9362E5F9.png F12F8427-BDC3-4260-9FC1-3BA2C58E7807.png

    Then I sewed vinyl covers with listing, I put tuck wires into the foam to hog ring the listing to, 73F44561-2F5B-48AE-8649-63BEBD99A388.png 0A374D90-87B3-4D62-8ACB-AA6067651948.png BAEE3376-E4EA-4D1E-8C3F-EB311B30571F.png 53E68B34-9660-44FD-9B22-BC457CF276A7.png this creates shape and separates a flat seat cover from true a true tuck and roll job

  7. Nice job! Between the seat and the wheel I'm getting a good vibe.

    Very Nice, - we need more threads like this. Thank you !

    I have always wondered how comfortable these ‘all foam’ seats are on a long trip, compared to original spring type seats with very little, if any foam on them ?
    Any comments ?
    Also you mention ‘dense’ foam. Is there any kind of rating on the density to identify which foam to use ? And how important is it to have the cut out section and webbing ? Thanks.

    53 pound foam on the cushion
    35 on the backrest
    The bolster is all 53 pound
    The cutout with webbing helps as far as I know
    Never tried one without
    As for comparing to original springs
    I’m sure a sprung cushion would last longer
    But these last pretty well and usually the spring seat is way too high

  10. Very important. It provides 'give' and breathing.

    Wow that’s very nice. @F-head would you mind sharing how to do the tuck wire in the foam? When I made my first seat I tried to get that roll of the horse shoe but couldn’t figure it out. Thanks

  14. Nice job...as a beginner to the upholstery side of car building, I really appreciate threads like this.

    "Then I sewed vinyl covers with listing, I put tuck wires into the foam to hog ring the listing to,"

    Can you go into more detail (or photos?) on your statement above...that part still seems like magic to me...how do you determine how wide the listing needs to be to get the propet amount of tuck? How and were do the tuck wires get placed? Is the foam cut for clearance of the listing? How deep etc.

    Thanks again. Excellent thread.

    Yeah, more explanation on the wires. Are they curved to go all the way around the outer edge of the insert, or just the straight runs?

    I cut a 1 1/2” deep slit in the foam where the cushion meets the horse shoe bolster it’s very important to make sure the slit is cut to an even depth
    I used edge wire bent to the shape of slit
    Shove it down into the slit using button twine shoved thru the foam with an upholstery needle, pulled tight and fastened on the bottom with staples or tied to paper wire,
    The lister is made from decking material and is sewn with a channel
    Best to cut the listing on the bias so it doesn’t unravel
    Sew the channel first then sew the lister on to the cover at the seam where the pleats meet the roll
    Should finish out at 1”
    That way you have 1/2” of pull down into the slit
    The channel on the lister gets paper wire which is hog ringed to the edge wire buried in the slit
    Start in the middle and work out always
    Hope this helps

    Here’s a seat with spring cushion and back rest I did for a friends 32 5 window
    On a spring seat the tuck wire is hog ringed to the top of the springs after the burlap underlayment is in in place 351FCD81-D7DC-4D97-AC0C-AED9DFDFC781.png

    Fantastic work! There's just something about a stock style seat in a 34 Coupe that looks so "right"!

    thank you for the informative reply.
    Just looking at doing something to mine now. This all helps.
    (I have a very comfortable van seat and a stock model a seat, and trying to figure out which to modify to suit).
