Only had for a week but very comfy. I’m about 5’6” and 145 and it’s supportive of my head and lumbar. There are many ways to adjust it to your needs. Set it up in about 30-45 minutes with one other person and fairly straightforward setup. And it comes with a 7 year warranty against normal wear and tear.
I bought one for me last year after getting tired of working at a dining room chair. I liked it so much that I got one for my wife who is also teleworking most days.
If you are going to be sitting in this all day you can do better. You should do better. You could do worse though. It is comfortable and easily adjusted.
