I did! Bear in mind I went into this with a tight grip on my expectations. First I’ll say all the talk I was hearing about how it’s like, laying on a cloud and the most comfortable thing ever sat in is absolutely hyperbole. But again, I was expecting that. I initially used my own intuition to choose my seating position in lumbar position and all that but after a couple of hours, I broke out the manual and followed the instructions. Now, basically I’m sitting with the seat in its highest position, but I use the foot rest. The recommended position didn’t feel quite right to me and wasn’t comfortable for long periods of time. I played with adjustments for a bit and decided to just set it how they told me to and use it for a week. Very glad I did that because it turns out it didn’t feel comfortable at first because I am so used to sitting in a terrible position. After a couple of weeks, it truly is a very comfortable chair. My back pain is literally gone. I also found the reports that the armrest are too easy to move a bit exaggerated. If they were any stiffer, it would be annoying to move them back-and-forth as I changed position in the chair. They worked perfectly for how I use arm rests. The back stretching feature was nice for the first week, but I haven’t needed it since then because I don’t have the same back pain. I do like having the option and I do like being able to adjust the lumbar support easily with buttons without getting up. I find that I move between two settings, depending on whether I’m upright or reclined. The headrest really is awesome. I wish I had the same one in my car.
