My cutting table is 36". It is on the bed risers. I'm 5'5" and the table is perfect for me. I have two other tables in my sewing room and both of them are on bed risers, as well. I have never had a problem with them not being secure. IN fact, my sewing table is on two sets of bed risers in order for it to be the height I want it. I sew standing up. Someone on another quilting forum introduced me to sewing standing up. My feet swell up when I sit too much. Standing has proved to be ideal for me.
