My neck was very stiff and my feet hurt after sitting in front of my work desk for a long time. So, when I had the chance to try Salli Saddle Chair I seized the opportunity. First I had Salli MultiAdjuster in my home office, because I already had a height-adjustable table there. At the moment I have also Salli SwingFit at work. I prefer Salli SwingFit because of the slightly moving seat, it is very comfortable when I for example want to take a file from a bottom self. Salli chair lives up to its promise. The condition of my neck muscles, my posture and the circulation in my feet have all improved. It takes a few weeks to get used to Salli, but I can warmly recommend trying it.
