Good chair at a decent price. Better than many more expensive chairs. That said it is a lower priced chair. The arms are not as sturdy as I would have liked. However I don't use the arms for support in rising so that is not a major concern for me. The lumbar support is a plastic piece that slides up and down for adjustment. It is cheap but I found it effective. I am tall (6'4") and found the chair comfortable. It rises tall enough to make my legs comfortable while sitting.
I use this chair both in my home office and my home sewing. I am a quilter who spends hours each week at the sewing machine and I reallt appreciate the lumbar support of this chair.
