I am close to finishing up as set of dining room chairs and have questions regarding the upholstery techniques. On my test chair several years ago I used a strip of 3/8" high density foam around the edge of the seat blank which I tapered to give a scooped seat. I then covered that with another
3/8" layer to smooth the scoop curve and add padding. On top of that I added 1" of what I believe was medium density foam and then cotton cloth and the upholstery fabric.I would like to increase the padding some. I have the FWW (#163) article from a couple years ago where they used 1/2" HD foam on the bottom, a rim of
1/2" HD foam around the edge, and filled the center with 5/8" medium density foam and a top layer of 1/4" low density foam. I like their edge HD with a MD center fill, but I'm a little concerned about the LD breaking down with time. I also checked Miller's book, but it used a simpler single density foam approach. My inclination at this time is to go with something similar to the FWW article and perhaps increase the thickness of the HD and MD somewhat.Are there any suggestions regarding the layer sequence, density and thicknesses that the experts out there have found to give suitable support and padding? Are there additional references that would be useful?
Thanks, Bob Abbott
