Chairs are tough. The closest I’ve been to comfortable in an office chair is the embody, but I still wasn’t in love with it. I could not stand the aeron.
Not sure what your body dimensions are, but I can at least give my perspective. I’m 6 foot and about 230. My legs are wide because I used to train them a lot. Because of this my legs push up against the outer edges of the seat. The aeron has a bucket type seat with hard plastic making the curve and my legs would always get cut into by that edge. My legs would be numb by the end of the day. The embody was much better but had hard plastic in the front corners of the seat that would push into my legs.
Still looking for a comfy chair. Have a gaming style chair (clutchchairz throttle) coming in to see if that works any better for me than traditional office chairs. I feel like I’ve already sat in the best of the best traditional office chairs because my jobs always gave top notch equipment, so it’s time to try a new thing entirely.
