The office chairs I purchased are suitable for my needs. They are simple and look good. I use my chairs about 1 to 2 hours per day so I expect they will function for years to come.
Bought two of these chairs based solely upon reviews for our home office. I found the assembly instructions simple and clear. 1. Color coding of screws: I don't have to dump all of the parts out onto the floor and sort them out into little piles measuring them against the photo in manual. Good. 2. Allen key is included: I don't have to look around the basement for additional tools. Very good. I'll admit like other reviewers have mentioned the wheel castors do not fit easily into the socket. You need to press VERY FIRMLY and turn clockwise at the same time (ahem...information that should be included in the assembly instructions) however that aside it wasn't an impossible feat. I'm a 5'9" 140 lbs. female and with a bit of determination was able to install them myself in under a half hour. I chose not to install the arms because it was a better fit for our desk space. The cushion is incredibly comfortable great lumbar support and nice tilt feature. The wheels are well made and roll smoothly on our carpet. For use reference I sit in mine about 20 hours a week my husband about 40 hours a week. Overall at this price point this far exceeded my expectations. Highly recommend!
