We have used these chairs for years (at home and at the office) and loved them! When we moved to a larger place we space for 2 home offices so we made the obvious choice and bought another one of these chairs. You can sit in these chairs for hours on end and feel literally no discomfort. The bungee does not dig in and in the 5 years we have had our original chair, has never sagged. I would choose this office chair every single time!
