This is a very comfortable chair and it makes my back feel better. It wasn't too hard to put together and I got excellent service in choosing and loading the chair. I am using the chair on a hard surface and the instructions suggested purchasing different rollers which are soft instead on the included hard ones. I looked at several stores and was unable to find such soft rollers in the major hardware stores here. But the original rollers work fine. Great chair!
My wife had back surgery several years ago. She now has 8 screws holding two metal bars on each side of her lower spine. This chair is very comfortable for her along with the lumbar support that allows her to sit and not be in pain. The most inexpensive chair in the store and actually the most comfortable. I tested them all. This one is a winner!
Had to get a new office chair working from home wore the old one out. This chair has been super comfortable for the past two weeks 6-8 hours a day sitting in it. Was on Sale for a great price.
The only thing holding the back of the chair on is 4 screws which connect to the arm rests none of which are long enough to actually hold the chair together. The holes for the screws don't really line up. This was a relatively expensive chair and it is already falling apart. It is comfortable and the perfect size for a small apartment I just wish the design was better.
