It's probably just me, but a cutting table at hip height puts a major strain on my back. I am 5' 2.5" and use the 5" bed risers from BBB with one of those fold up buffet tables. This puts the table almost at waist height for me, about 34" - just about the same as regular kitchen counter height. My friend who is 5'6" tall likes the 7" risers.
My Singer Golden Touch N Sew came with a cabinet that is 30.5" tall. The sewing machine sits level in the cabinet and is a very good height for me. I always use a pneumatic chair that turns. Anything else gives me a backache very quickly.
My kitchen table is about 28" tall. Having a sewing machine on it puts the level sewing area at 31" to 32". Not as good, but not a horrible height. The key for me is being able to push my foot pedal without having to reach for it.
Edited to add: At the age most of us are.....it's whatever works that doesn't cause us a lot of aches and pains as we are doing it or afterwards.
