I am 6' tall, so totally understand anyone who has back pain from being stooped over to cut fabric. I am very lucky that my husband asked a friend of his to help him make a cutting table for me. DH found a picture on either Horn of America or Koala sewing furniture & made a table that was to my specific height for me. Both sides fold down when not in use & I have storage from two sides underneath. When I am basting quilts, I have 2 - 6' folding tables that I set up & I put the bed lifters under all the legs, so it's a good height for me.
If you have an IKEA anywhere near by, they have tables with legs that adjust up or down. You can also order from them.
