Disappointed
I'm taking stock after more than a year of use.
At the beginning it was good, comfortable, the settings simple but sufficient. I was able to do sessions for several hours in a row without any problems. But for some time now the chair has been changing position by itself! I have to readjust the height regularly and it's getting annoying. The foam ... the foam has lost its comfort.
With hindsight it would have been better to take the higher range.
