OK, I had to check this out. My sewing table is 31 inches from the floor. My machine drops down onto a platform below surface so that it is flush with the table. My husband built my sewing table, an "L" shaped arrangement. I have 2 sets of drawers in the desk. The top drawer on the left is a pull out ironing board. I have a chair that is adjustable and set so that my feet rest flat on the floor- at least the left one. When you sew you need to be in a good posture position so you don't stress parts of your body. I am really aware of this when I use my serger. It sits on a standard folding table. My chair is a folding table. It is not comfortable-fortunately, sessions in that situation are short.
