Presently, I have an old 1950's vintage chrome and vinyl-plastic seat, (with 2 foam cushions on it) but I'm looking to replace it with a 24-inch bar stool, with swivel seat, no arms and 4-on-the-floor legs...no wheels for me! Then I can easily sit down, but not too far down, and just turn/swivel myself into position beneath my sew. machine table.
I'm relatively tall and have long legs, but aging hips and knees and I use a regular sized dining table height. It helps to be in an ergonomically correct position.
Hope that helps.
