This chair strikes just the right tone for me with the mesh fabric for breathe-ability and also for my back. It didn’t say that it was specifically good for lumbar issues but I love the way the seat is designed and where it hits my back and supports it. Very happy.
Long-term performance is still up for judgment but otherwise this chair works well for me. It has several adjustments to make it suitable for anyone or for different needs. A few facets I would like to see improvements on however: 1. The height adjustment slips so it has to be re-adjusted from time to time. 2. The lumbar adjustment is too limited in the range of adjustment. 3. The various levers for adjustment are often difficult to reach; they should be slightly longer for greater ease. 4. I don't know if there is a better way to design it but the chair curves upward on the sides making for a nasty and painful seat when you hit it at an angle other than straight in front. This is the most expensive chair I ever bought so more expensive chairs may easily be better but I would estimate that less expensive ones are very close in usability at least for the short-term.
I tried every chair in the store before deciding on this one. I was able to leave off the arms because of where I use it. The only problem was inserting the casters. I called the Help line and received suggestions that didn't really work. However I found that by rotating the caster slightly and pushing a few times it would slip in.
I have had my chair for over a year and it has held up well to lots of use. Therefore when I needed a second office chair I wanted the same one. When checking with Staples on line it showed that they were not in stock anywhere nearby but drove to the store and they had several. They are easy to assemble and very comfortable for long hours of sitting. I like the fact that I can adjust the chair height arm rests and lumbar support. Great value and great chair!!!
