I purchased this chair because I wanted to replace my old one that had no arms. I love the ease with which you can adjust the height of the arms. It's also easy to adjust the chair height lumbar support and stiffness of the chair back. The chair was fairly easy to put together and they include all the parts with labels instructions with good pictures and an Allen/hex wrench.. At first I had a little trouble getting the casters to snap in but found that if I pinched the metal C-ring on the stem a little tighter with my finger and thumb first then they snapped in more easily. I like the mesh used for the chair as it's both comfortable and lets the air flow through to keep me cool.
It’s a 5!! This desk chair is very comfortable in my home office. It can be easily adjusted to fit individual needs. At a reasonable price it is well worth it. May recommend this to be purchased by my work.
Before this chair I had a nice cushy office chair that took a lot of space. It had no lumbar support and neither did my living room chairs. I had chronic/acute lumbar pain. This chair made all the difference in the world. That pain left within 3 days. Wow! I looked forward to sitting in it!
