I have had my Iskur XL for about 2.5 years now. Over the past few months, I realized that the chair leans to the left when I sit in it and it's getting worse. The left side is lower than the right by about 1/2 inch which doesn't seem like much but it means my arm rests don't line up with my desk and is starting to cause wrist issues.
Does anyone know what I can do to try and fix this? Again, it's only when I sit in it, otherwise it's level (yes, I tested this with a level)
