Overall is good good and simple design with a comfortable results; assembly instructions are clear and simple but it has a minor defect in the metal frame.
Our previous chair was shedding little pieces of a thin leather type material and needed to be replaced. We wanted one quickly to replace it so I was limited to what was in stock. Mostly you find one you like and buy one in a box with some assembly required. This one was very comfortable and had all the features we expected with height adjustments recline and lumbar adjustments. The mesh seating and back are comfortable and provide good support while keeping your back and seat cool. Since they had two of this same model on display I was able to buy one of them already assembled.
I bought this for my husband. He has an Aeron chair at work but now must WFH due to the pandemic. I put it together quite easily by myself. The hardest part was unwrapping it - it was well packed. Obviously it's not a Herman Miller but it's a good substitute and priced very well. My only complaint is that it isn't more adjustable. I like that both the seat and back are mesh (nice and cool) and that the lumbar support is somewhat adjustable (up/down). The armrests are basic but adjustable. The head rest is slightly adjustable but not really hi/lo more just angled or not. This is uncomfortable for me (5'9") and my husband (6') but my 5'1" daughter finds it very comfortable. Luckily we were able to just leave the head rest off. My husband uses it for more than 10 hours a day. Prior to buying it he complained of low back pain daily. Now no complaints. The chair fits nicely at the dining room table and rolls well on both the carpet and the wood floor. Overall I definitely recommend this chair.
I purchased this chair based on online reviews and I have to say overall it's pretty comfortable. Where it misses the mark is the headrest - I tried using it as-is and found it to be more of a hindrance than added comfort. I also tried the online mod to extend the height but no dice. Otherwise the chair serves it's purpose at an otherwise decent price.
Very clear assembly instructions and hugely comfortable. This is the fourth Hyken Mesh Task Chair that my family has bought. One of our sons who has chronic back problems reported that after one month of using the chair his back is 100% improved.
