My chair is an old wooden, high back dining room chair. I don't even remember where I got it from. There are no permanent cushions anywhere, not even the seat. I use a home-made lumbar support that sort of looks like a small version of a bolster pillow that has a weighted "tail" that gets thrown over the back of the chair. The tail is weighted with lead sinkers procured from someone's tackle box. Shhhh! This keeps the "pillow" in place while I'm sewing, and it makes a terrific travel pillow as well.
