Expensive chair to out right buy with out sitting in. If I were to try it first, I would not of purchased it. I bought it on sole of reading other reviewers.  Luckily I was able to donate it to my office to get it out of my sight. I found that it was not comfortable for my back and found my self slouching over time. The base cushion is tall and wide but did not not give me the sense of fitting in. When I sit in a chair, I like to know that the chair holds my frame. This chair seemed to have lots of room where I could not possibly fill.  The base cushion where it meets the lumbar location in the back for me was not at the correct angle. The lumbar was able to be adjusted but not the seat back articulation, which made for difficult posture correction. I did not get that nestled feeling in this chair. I'm a tall guy and even though the seats are good for sitting in extended periods,  my body as a whole waist up was not in favor for this chair.
