Have run formway life chair for years, and have sworn by it.
But with moving countries, it was going to cost around NZD1000 to ship both my and my wifes, so ended up giving them away.
Such chairs are rare here in Austrailia, but I have found a source at under AUD200 each.
Question is should I spend 5x the money and get a Herman Miller Aeron Remastered (used), ergohuman, steelcase or something else. or stick with what I know and love?
