Been working about 11 hour days at my desk and I rarely notice any sort of discomfort from sitting too long. I get up every now and then but it's not like it's the chair giving me problems. If you can snag this chair for around $100 you're getting a good deal.
The desk chair thaT I had was more eXpensive but unsafe because it was slippery and I had do be very careful how I moved around in it. I bouht this kroy mesh chair because it was not slippery and held fast no matter how I MOVED AROUND IN IT.i FEEL VERY SECURE IN IT. IT'S PERFECT FOR ME.
Very comfortable office chair for the money. Easy to assemble and it adjusts easily to fine tune the positions of the arms lumbar support and chair height. I personally felt it was a better "sit" than a chair that was double the price. Fantastic lumbar support and the chair in general is one that feels good from the start of the day until it is time to go home at the end of the workday. I'm 6'1" and it fits me very well. I've had it two weeks and can easily share I would recommend this chair - to the point I'm considering getting one just like it for my home office.
I purchased this chair as a graduation gift for my sister. Since she has some back pain I took her to the store and had her select the chair. Upon sitting in this one and realizing the benefit the lumbar support provides she quickly choose it and is completely satisfied even now after several weeks. It was shipped to her home the day after I purchased it as promised by the store employee and it was simple to assemble. I'll definitely return to Staples the next time I'm in the market for a new desk chair.
