i saw this at a quilt show recently and i can't wait to get one. I tried sewing on it and was amazed at how comfortable it was - and how my bifocals adjusted so well. Truth is one can also put a couple magazines or something else under the back side to raise that up.

There is a thread from long ago on this. It had a whole article that related to how the person's height determined the height of the table and chair. If I remember correctly it was from a government document.
I have a table that is lower than and when I sew I don't have to stretch to see where the needle is going. My Dad created it. That wouldn't be everyone's answer, but it works for me.
