Simple adjustments, excellent comfort and high quality materials and construction. If this is what you’re looking for, the Run Task Chair by Via might be the perfect choice. This chair has a height adjustable seat and height adjustable arms that move with the touch of a button. A tension knob underneath the seat allows the user adjust the resistant of the reclining motion. A lever allows the user to lock the chair in a reclined position or an upright position. A mesh back increases breathability and molds to the back to provide comfort and support. Choose from several color options. An optional polished aluminum base creates an executive look. Optional hard floor castors have a rubberized finish, creating a smoother and quieter rolling experience on hard surfaces.
