I did not assemble it but was told that it was a little bit complicated. I cannot speak to durability as I have only had it a short time so far. I do love the neck rest and it is very comfy. Overall so far I am happy with this chair.
The chair was on sale so I bought it. It is similar to chairs I used at work but with a better price tag. I paid to have it assembled so I did not have to be frustrated by that. It is very comfortable and is exactly what I needed to be able to work ergonomically at home since I work at home most of the time now.
I have a lot of neck/back pain and I worked with my physical therapist to find a chair that would fit me- I am 5'1" and most chairs are too tall/too deep. I did have to take the headrest off because it was too high to fit my head comfortably -but even without it the chair fits well and allows me to sit at the computer for longer periods without triggering the neck pain.
We purchased this chair for our home office and are very happy with it. This chair is very comfortable and also very good looking. The breathe-ability of the mesh fabric helps me stay cool no matter how long I sit in it. The ergonomic design promotes good posture for sitting at a computer desk. The home delivery was quite convenient and the chair took only about 20 minutes to set up. Definitely a good value for the money. The only small drawback is that the headrest has limited adjustability.
My work purchased 2 of these and both of us love this chair. It is the most comfortable task chair I have ever sat in and I love the support it gives. It's great not having to sit on the edge of my seat because this chair FITS me.
I use to only get the leather type chairs from staples but they would last about a year before becoming about as comfortable as a park bench. I tried this chair out and was amazed as how comfortable it is. I think its pretty comparable to the more expensive mesh chairs. I would recommend this to anyone that spends a good deal of time in a chair at their workstation. I've had it about 2 months now and its just as good as the day I got it. Hopefully this will be the last desk chair I have to purchase.
