I got the large chair as I'm fairly tall. The instructions say to shift the seat forward to properly support your legs, but this means if you're back in the seat, your tilted back from the base angle. The seat also isn't particularly comfortable.

I purchased this chair about a year ago, and I wanted to really test it out before sharing my thoughts. Unfortunately, it hasn't quite lived up to my expectations. I cant stay comfortable for more than a few hours on it, and I have tried all kinds of office chairs prior to giving this a go.

The neck support digs into my neck more than I’d like, and I can’t seem to adjust it further back, which is really frustrating. While the low back back support is adjustable, it’s too firm for my liking. I’ve tried adjusting it for comport, however, the said neck support becomes uncomfortable as it now juts out. I do manage to find a slightly better position by moving it back and locking it in, however I still struggle to sit upright and work without discomfort.

The arm rest also sits too high for me, and get quite annoying after sitting in the chair for a while.
If I’d paid a couple hundred bucks for this chair, I could see it earning a solid 4 stars. However, given the premium price tag, it only deserves a 1-star rating from me.

I spend 10-12 hrs per day at my desk in front of a computer. I have bought many office chairs. This is the first one I've bought that I have not been stiff and sore at the end of the day. I'm 6'2" and find it comfortable, roomy and supportive. Its great!

I purchased the "Supreme" chair about a month ago. The chair was delivered unassembled as stated. The first thing I noticed was the build quality and that assembly took about 20 minutes as promised. A chair of this quality and with the ergonomic features can cost well over $2,000....I paid about $750 via Amazon and I am very happy with the chair I received for the money I paid. If you do work from home and need a quality ergonomic chair I recommend the ErgoTune Supreme.

I am very happy with my Supreme ergonomic chair. It is very comfortable and adjustable in so many ways. The arms are adjustable for multiple positions albeit I feel they are naturally a little too wide. for my frame. It's a solid, well-built chair with quality parts . It assembled fairly easily with good instructions. Overall, very happy with the purchase. You get what you pay for with office chairs and this is a worthy investment.
