I’ve been using this chair for a week now and I’m very happy with it. I sit in it for about 5 hours a day to work at my computer and I don’t feel any discomfort. It was easy to put together. It has a lot of adjustments to make it perfect for your own body. You can adjust the height of the chair the height of the arms the height of the lumbar in the back the tilt of the seat and the tilt of the back. Ignore those reviews who complained that the seat is tilted too far forward and they feel like they’re sliding to the floor they must not understand how to use the simple lever under the seat that allows you to adjust the amount the seat tilts forward when I adjusted this lever and locked it in place my seat is not tilted forward at all and my butt is level.
For some people who LOVE shopping on line . . . sight unseen maybe this works for them. However for a 70 year old woman this is too difficult to adjust - way to many options! Also on the chair I received the fabric covering the lumbar support in the back is already coming undone. I would NOT recommend this one for elderly people. As difficult as it is I will continue going to the establishment selling office furniture so I can see for myself the quality and workings of the item I'm looking for. I really tried to work with this particular chair - it just isn't meeting my needs. My Mistake!
