Get ready to laugh.
I am tall. I am nearsighted to the point of having to be aimed at the right wall come eye exam times. Okay, a slight exaggeration but very slight. Discovering trees had leaves was a wonder. I thought those were green halos. No, I wasn't old enough to drive when we made the nearsightedness discovery.
So between tall and very nearsighted, I have my machines raised. On a normal height surface, on upside down rectangular baking pans that rest on sheets of no slip shelf liner. One pan per machine. That 2" does the trick. Lowering my chair was a no go - elbows got in the way.
You may all wipe the tears of laughter from your faces, blow your noses, and keep on with what I hope is an especially nice day.
