I just found out recently that I have a herniated disk in my low back. My work bench is a stand and work kind of bench. I do have a bar stool to sit on but I still have to limit my time standing to about 20 minutes on then about 30 to 60 minutes sitting taking a break. I'll be changing one of the work benches to a lower standard table height now and using a roll around chair. But a stand and work table was sure nice while it lasted.
