I described the beginning of the recushioning of the vintage dining room chairs here.
After finishing the webbing on the first frame I decided that I had used too much webbing and so reduced the remaining chairs to 2 vertical pieces and 2 horizontal pieces.
Next step is to cut and attach a fabric layer over the webbing.
Some sites call for burlap; I used unbleached cotton muslin.
Trace with a marker the outline of the seat frame onto 1-inch high density foam. I used foam that was already approximately the size of the seats. I laid the front edge of the seat frame against the edge of the foam so only three sides would need to be cut.
I carefully trimmed the excess with scissors. (My preferred method of cutting foam is an electric knife but I couldn’t find ours.)
On top of the foam a layer of batting is applied that is just a bit larger than the foam.
Finally a layer of the upholstery fabric is cut with enough excess to totally cover the top and sides of the cushion and be pulled to the underside for stapling. After the fabric is cut but before it’s applied is a good time to iron it.
Starting with the front put a staple in the middle of the upholstery fabric. Pull it taut to the back of the cushion and staple again near the center. Then do the same on both side making sure the fabric stays on the straight of grain.
Adjust the corners so they lie flat in a neat pleat.
Staple all around the perimeter of the fabric pulling taut to remove bubbles but not so tight as to pull on the bias.
Place the newly upholstered cushion into the chair.
What project took you a lot longer than expected?
