I had set my eyes on buying a high end ergonomic chair. After reading the reviews on the Hyken office chair I decided to visit a Staples store to try it out. The Hyken was nice but a bit small for someone 6" tall. I saw the Dexley which the staff member said it was just a "larger Hyken". It seemed well-built. And for an extra $20 you get a 3-year parts/labor warranty. My son uses it for school. So far so good. The Dexley was 1x-4x the price of a high end ergonomic chair and seemed similar in performance. I am happy with the purchase.
It's not a Aeron but it's my dime not the bosses. I'm 6'4" and have had a Hyken as a gaming chair for the last 7 years. Wow what an upgrade I actually had to find the best setting for me instead of everything at max. Loving it so far.
This chair is very comfortable but cool due to the mesh seat and back. I put a towel over the seat and back to keep air from coming thru and giving me a chill.
