I have worked as a senior lawyer for 20+ years, before which I was a professional Rugby player. This combination has meant that my lower back has always caused me some problems. I had tried all manner of ergonomic seating. The only which has led to a demonstrable, marked improvement is Salli. I cannot recommend Salli seating highly enough, particularly for those of us who sit for long hours each day.
