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!
