After the leather and padding was removed, I cleaned the chair with soap and water and wiped it dry with paper towels and determine that was all it needed. I was lucky the chair looked great and I wanted to keep its patina as is. The old padding was replaced with a ½” polyester padding and staple in place. Then the leather covering was cut to slightly over lap the padding and temporarily tacked in place. Four 1” wide strips were cut about 4” longer for each edge. I marked a center line along the length on the back side of each strip and apply double sided tape down the center line. Next I pressed/folded the both raw edges to the center line forming my taped edging. The tape was used to cover the raw edging on the leather seat covering. I then placed painter tape on all four side of the leather cover and marked out how far and how many tacks were going to be used to hold the leather tape in place. Now I could staple the leather cover down in between the tack placement.
The center of each leather strip was place on each center edge and then tacked into place. I worked each side from the center out placing the tacks ¾” apart. Where the strips meet in the corners, the strips were mitered cut and a tack was place in the center of the cut to hold it in place. Here is the finished chair. I much prefer this to the original.
The total cost to redo this piece was less than $5 since the leather was left over from this other project.
