The moment I sat in the Focus chair, I immediately said "Ahhhhhhh" - and again every time after that - the entire evening after I put it together. I rarely feel that kind of comfort in an office chair, even though I am used to sitting in very expensive commercial office chairs at work. This is definitely a great value for an office chair. Not only is it sturdy, good looking and well-constructed, it is extremely functional, versatile and amazingly comfortable. Kudos to Lexington Modern for delivering such a great chair at an affordable price!I ordered the Focus office chair with the leatherette seat because I loved the arms that flip completely up and out of the way and because the curve of the back seemed as if it would provide more support. I AM NOT DISSAPPOINTED! I absolutely love this Focus chair - waaaaay more than another ergonomic chair that I had previously ordered and that cost $100 more! The Focus chair is very good looking, very comfortable, has excellent back support and the arms work perfectly in allowing me to scoot up to the desk with no problem. Yet, when I want to sit back and read, I pull the arms down and they are at a perfect height and angle for me. (I am female, 5'4", average build. However, I find that chairs that are comfortable for me are also comfortable for my husband, who is 6'3".) I should tell you that I am an interior designer who has frequently evaluated ergonomic office chairs for commercial clients. So, I am very aware of what an ergonomic chair should feel like and how it should function. This one does. While it does not offer all of the adjustments and other bells and whistles that a high-end commercial office chair would have, it does offer exactly what I need in an office chair: lumbar support; seat comfort with firm support and a waterfall front to take pressure off the back of the legs; flexible arms; and, NOT least importantly to me, it is a very good looking chair! This chair is much better looking than most every other task chair that I have seen in local office stores. I ordered the leatherette seat rather than the mesh seat because it had a higher rating, by other reviewers, than the same chair with a mesh seat so I assumed the construction of the leatherette seat must be more comfortable. While I am not usually a fan of "leatherette" materials, this material feels soft and looks very much like real leather so it is a non-issue for me. The contrasting top stitching around the seat is very handsome and suits the look of the chair, a nice added detail. Also of note, this chair glides relatively easily across my office carpeting, which has a pile height of average residential carpet, so I will not have to use a chair mat (which I hate).As I previously stated, this is the 2nd ergonomic mesh back office chair that I have ordered. The first ergonomic chair, made by another manufacturer and not ordered from Amazon, had an average rating of 4.6 stars (out of 5 stars possible) by 132 reviewers so I figured I could not go wrong. Everyone raved about the chair's comfort. For $250 (which was supposedly a deep discount of the chair's original cost), I received a very average looking chair that did not fit me, did not provide any lumbar support, would not slide into the knee space of my desk because the arms were too wide, and was very difficult to move across my office carpet. Even though the first chair had many more adjustment options than the Focus chair, it was not nearly as comfortable at any adjustment setting. I am returning it, even though disassembling the chair is a real pain.
