3-29-14 Had to add to my comment. Have had this chair now about 2 years and can't say enough good about it. It still looks as if it was new even though I use it constantly. Maintains its position so I don't have to adjust height, upholstery still looks like new, rollers work smoothly, and it is comfortable. You won't go wrong purchasing this chair. Another terrific Amazon purchase!!!6-28-13 I have had this chair for almost a year now and use it every day, sitting in it for 6 to 12 hours a day (I am retired and do everything over the computer including games). It looks like it is still new. It is so comfortable to sit in and the height maintains it position so you don't have to continually adjust it, the rollers still work smooth, and there are no cracks or wear marks in the upholstery. I can't say enough good about this chair. I worked in an offices for 40 years and would have never believed a typing chair could be this comfortable and retain its new look. You won't go wrong purchasing this chair.Dec. 5, 2012 UpdateI use my chair every day and usually for hours. I have had no problems with it. It is still comfortable, rollers roll smoothly, holds its height (doesn't slip down). Upholstery maintaining its appearance with no cracks or wear spots. I couldn't be more satisfied. Would buy the chair again with no hesitation and highly recommend it.Sept. 11, 2012 UpdateHave now used this chair every day for a month and love it. Comfortable to sit on (being retired I use my computer for hours each day), rolls easily (on carpet), upholstery has leathery feel, and is a nice size. Would definitely buy it again and highly recommend it.8-11-12This is a fantastic chair. I am a 75 year old woman. I opened the carton,assembled the chair and was sitting on it in less than one hour!!!! If I can doit by myself in less than an hour, anyone can do it.Three Hints: 1) you will need a decent sized Phillips screwdriver. The one Iused is 8" long and fit the screws perfectly. 2) you may not need the top pieceof the cone (the smallest piece). In my case the seat would not fit so I tookthe top small cone off and the seat fit perfectly. 3) The lever to raise andlower the seat has to be on the RIGHT hand side as you are sitting on the chair.Instructions: Either go to the Boss Chairs website or use this link to godirectly to instructions: [...] . Thewebsite has an visual that literally shows you how to assemble as well aswritten instructions, and a very good diagram of how to assemble the chair.One is animated and literally shows the chair being assembled.The upholstery on the chair (LeatherPlus) is very rich looking and nice to thetouch, and the seat and back are padded. This chair could easily be at a desk inyour living room or office and look very nice.I highly recommend this chair and would definitely buy it again.
