I put Velcro dots on the bottom of mine. Because I am short and have to use a table to sew on, I found I was having problems with my back, hips, and neck. I put a large book about 5" thick under my left foot, and a book about 4" thick under the pedal. End of back and hip problems. 2 rubber door stops under the back of the machine to tilt it forward so I don't have to lean over the machine to sew got rid of my neck problems. Total cost, $2 for the door stops. Result, no more pain.
