ESD chair for home workstation
You do not need a full ESD chair IF it has a seat cover or brass mesh that is grounded through a 1 Meg resistor, much like a wrist strap would be, or your wearing BOTH a ankle/heel strap and wrist strap. NEVER directly ground ANY part of your body, because if you do touch something &quot;HOT&quot; you could get a nasty shock. Twice a given voltage will cause it to dissipate 4 times as much energy into your body. 480 VAC will hit you 16 times as hard as 120 VAC.
You have the option to wear ankle/heel straps which keep you safely grounded regardless of chair type, and is what many MFG plants use, along with wrist straps. Once your body is safely grounded your concern turns to making sure your parts containers are the anti-static type.
Do NOT use conventional plastic bags or trays for electronic parts. I have seen many LED's and CMOS IC's get blown this way. If you were doing contracts for NASA then maybe special chairs and netting would be part of the expected cost.
If you are wearing BOTH a wrist and a ankle/heel strap you take yourself out of the static-source equation, so you can pay attention to other static sources such as plastic containers and plastic tools.
