This chair is nearly perfect and I would only suggest minor changes such as the headrest being able to raise/lower instead of being stationary at one height and being able to bring the arm rests in tighter to the chair (width of the arm rests) and being able to lower the lumbar support just a smidge further or even retract it a bit.
Chair is decently comfortable but makes loud snaps and creaks when I lean back. Will contact Tech Support for resolution. Kind of shock you when you lean back and there is a loud SNAP!
Well generally I like the chair. After about 1.5 years the mesh is still okay - no rips. Unfortunately the nylon base developed a crack and now the gas piston is literally dragging on the floor. Replacements under warranty are on-order but won't come for probably 2-3 months so I'll probably have to try to buy replacement parts (assuming I can get this thing taken apart) even though it's still under warranty.
The mesh seat is tearing where it's attached to the frame on the side after 8 months of use. I'm 165 pounds I didn't expect to have to replace this within 1 year.
