I really like my chair. Based on the reviews I was prepared for the green color to be more turquois and it suits me better.
The truth is that it was very difficult to put together alone as the holes on the seat bottom did not align with the holes on the wheel's plate. Since my husband was away and I really wanted it done I had to really push on the chair back to get some alignment. When I was done 2 of the 4 screws did not lay flush like I know that they should, I stopped when they were tight so as not to strip the treads.
With that said the chair back is firm and there is no gap between it and the seat. It is comfortable and the wheels do not rotate well. I still think that it was a good value on sale.
