This is a comfortable and sturdy chair...I had a hard time finding a good armless chair for sitting at my work table and this one fit the bill. I am not a thin person and this chair is up to the effort...good support, nice wide surface. There is no lumbar support to speak of, but a folded pillow does the trick; chairs with all those fancy supports costs lots more and the actual location where support is needed varies.  A great value for the price; I would buy this again.
