This chair was bought as a gift for someone needing lumbar support while working at his home office. He says it's comfortable and was easy to assemble. So far so good.
I'm 5' 8". The chair fits me perfectly. the lumbar adjustment is a nice feature. Even though it doesn't move much I am able to position it properly. I really like that the back is variably adjustable to position it. Sometimes I want the back more relaxed and this feature gets me there.
