I'm 5'9" and my old church banquet table is on PVC posts.
It stands 35" tall and is 7" below my arm with bent elbow.
I have multiple herniated disks in low back and this is the most comfortable height for me.
I just purchased the end caps to put on the leags so they don't have to sit in theses little plastic thingy's anymore.
