A few years back we put in new counter tops, etc. in my sewing room. My machine sits down into one of the counter tops, but my chair was still to short. My husband took the chair base off from the bottom of the chair and then put a big block of wood between the bottom of the chair and the base. This made my chair tall enough to use at my new counter tops. But . . . my feet wouldn't touch the floor. So he built me a box about 8 inches deep and 2 ft. long and probably 6 inches high to put my foot pedal and my other foot on. He's a keeper!!
