Continuing with the upholstering procedure:
My box seat spring unit has sides.... or front, back and side faces. These
faces don't need to be padded or padded as much as the top of the seat.
I would think your seat would be padded similarly as I've padded this outdo
Referring to the additional pics:
The spring/seat unit is covered with (synthetic, white) burlap. This burla
p layer doesn't need to be tight, just snuggly fitted and attached/stapled
The very top surface of the seat is padded with 2 layers of cotton, which b
arely overlaps the edge wire. The edge wire needs to be padded, so that it
isn't felt, when sitting on the seat. A third layer of cotton is applied,
not only on the top surface, but it also droops down the sides, covering t
he sides/faces. You might prefer 4 layers of cotton padding, for your high
er-end Morris chairs. As mention before, for a good quality chair, I would
n't skimp on the interior paddings and a layer of 1/4" felt, on top of the
burlap, prior to the cotton, would be my choice, if they were my Morris cha
Next pic shows a layer of fiberfill/batting, covering all the previous padd
ing. The edges of the fiberfill are attached to the edges of the ply base.
The seat is ready for the upholstery fabric.
