Seat base retrimming

 Time to do the seat base now.

The foam needs a fabric covering underneath so that the webbing straps don't cut into it. Don't know what would have been original for 1972. I had this burlap on hand, so that's what I used. 

 

 

It's glued lightly to the cushion to keep it in place during assembly.

 Where the seat cover center panel will fit into the depressed area in the cushion, contact cement is applied to the corner edges of the foam, the lengthwise seams in the cover, and the center panel. It's important not to over-apply the glue. It mustn't soak deeply into the fabric or it could collapse the padded pleats. Just brush sparingly over the surface. 

 

 

 

When the contact cement has gone tacky, the inside-out seat cover is folded so that the center panel can be laid into the seat foam and aligned along the center edges on each side.

 

 

Before the cover and seat foam can be attached to the seat frame, the seat back should be temporarily assembled to the seat base frame so that the alignment of the bottom covering center panel can be aligned to match the center panel of the back covering. When the best position is found, then the bottom cover and frame are marked for reference.
 

 

 

 The bottom cover needs to be cut in several locations for wrapping around the frame. Cuts are made where the covering can be folded under so that there's not a raw edge visible. 

 

The folding and tucking of the rear corners may be a bit of a puzzle if you don't have a reference.

 

 

 

 Job complete!
