This chair has a very sturdy frame. The steel wrap around bar and construction make it feel very solid, and I believe it will last me a good while.  The padding is soft to the touch, and seems double layered like a pillow top mattress, initial very giving, but firm before it gets hard.  The lumbar support is perfect for me (6'1" with a large arch in my back). 

The seat is not very deep, but is very wide.  It waterfalls off a little sooner than I would like.  The chair also does not tip back as far as other chairs I've had.

Overall, I'm extremely happy with the purchase.
