Very comfortable chair very good back support.. Lift was very short (around 3" ) had to order separately 5" lift (15.5" full extend ) and substitute.. after that the chair is almost perfect...
I think these are going to be fantastic home office chairs. So far have been happy with everything about them: on-schedule delivery very well packaged with the best assembly instructions (English speaker written color coded bolts) I’ve ever seen. It took about 40 minutes to put the first chair together but only 20 minutes for the second - I’m trainable! We purchased these chairs because we had tested out dozens in multiple stores and didn’t like any of them. Then we walked into a Staples store sat down in two Hyken chairs and my wife and I looked at each other and immediately said “These are great!” Ergonimically sound adjustments and an especially good lumbar support for your back. Components were very solid - indeed heavy - and the mechanisms looked quite durable. The chairs have a modern look and the grey mesh matches our desks and bookshelves (purchased at Scandinavian Design Denver). Long-term concern about durability of mesh but we’ll see.
The good part is the chair sits higher than my old one so my feet can sit flat on the floor and my ankles knees and hip don't hurt as much. The down side is I have a wide butt and this is made for a narrow one. The contoured bottom pinches my bottom so I have to use a pad. The only chair pads are too small. I might recommend this for a tall skinny person.
