I had hoped the one-star reviews were wrong, but they were right on.  Day one and two were fine, day three my back was so sore and I was so uncomfortable that I switched back to the temporary wooden dining room that I had been using.  The seat tilts down in the front so far that I have to lean against the desk so I didn't fall off.  The padding on the seat is worse than a wooden chair.  The mesh back is much too bowed.
