Flash FurnitureNicholas Mid-Back Swivel Desk Chair with Wheels, Mesh Back, Padded Seat, and Armrests, Adjustable Height Mesh Ergonomic Office Chair, Black

Very sturdy, exceptionally easy to assemble, and every adjustment you could want. Goes at least a few inches higher than I need (I'm 5' 11"). Here's a list of the possible adjustments:1.) Seat height - paddle control.2.) Seat angle - paddle control, sets the angle of the seat bottom and back together (see #4 below). Can be locked in place, or pull the lever all the way up to allow the seat to rock freely.3.) Ease of rocking - adjustment knob located under the front of the seat bottom. Adjusts how easily the seat rocks if the above paddle control is in the "Up" position.4.) Angle of seat back - paddle control. Allows for independent adjustment of the seat back. Can be locked in place, or pull the lever all the way up to let the seat back move freely. (Seat back is spring-loaded to move forward; the spring is a bit heavy and applies more pressure on my back than I like, so I lock this one in place with the paddle control.)5.) Armrest height - buttons under each armrest allow them to be raised or lowered. There are six positions allowing adjustment over about a three inch range.6.) Height of seat back - an adjustment screw can be loosened allowing the seat back to be raised or lowered over about a three to four inch range.

For the price you cannot beat this chair. I've had the same office chair that I bought from Wal-Mart over 6 years ago, and it got so flat it really hurt to sit in for more than an hour. After upgrading my personal PC and getting into some longer gaming sessions, I knew I needed something that A) wasn't fake leather and B) had all of the support and adjustments I needed to personalize my sitting posture.This chair delivered on all accounts. The breathable mesh on the seat is thick, retains its shape, and the back is comfy yet durable. It was simple to put together, the rollers are high quality, and the adjustments are all strong and hold well. I can game for hours in comfort without having any pain in my legs or rear. The only gripe, and it's a small one, is the armrests are very hard. They work great for mouse/keyboard, but extended typing or using a gamepad and resting our arms against them at an agle really hurts your elbows after a while. I don't expect soft, padded armrests but that's just something to be aware of if you're buying it to game or you type a lot.I will buy this chair again when/if the first one wears out.*UPDATE 12/17/2015 - I still really like this chair, but the armrests have become the worst I have ever used. They're FAR too tall and can't be adjusted down far enough. After I have played Fallout 4 a few nights with an Xbox One gamepad, my shoulder is sore and my elbows are hurting. I ended up just taking them off and it works out, but I can see why more popular "gaming" chairs have armrests that adjust far lower or fold away. I'd still recommend this chair to anyone who works in an office, but for gaming use...probably not the best choice.

I've been using this chair for 5 months before I wrote this review. I've had no damage issues and the quality hasn't declined with daily use.This chair is a good purchase for the price and quality of the product. I'm 5'8" and around 145 pounds. I use the chair daily, and will be in it for 8 hours a day during college terms. The chair supports my lower back well, and the mesh on the back of the chair is firm enough to support but elastic enough to still be comfortable and conform to the contours of my back. The chair has enough adjustment mechanisms to keep the support focus on the lumbar spine, while tilting the seat at the correct angle to prevent tingling in the lower legs. The seat has firm cushioning, which keeps the chair comfortable and doesn't generate sore spots after repeated hours of sitting. Assembling the chair was simple enough. If you can assemble IKEA furniture, you can assemble this chair. I had no issues with shipping damage.I will mention 3 downfalls to the chair. First, the arm rests tend to rattle around when they're in the lowest possible position. The rattling stops if I raise their height, but the desk I sit at won't allow me to raise them beyond the lowest setting. While it doesn't affect the quality of the chair or how I use it, it's fairly annoying to hear the rattling basically every time I move the chair to sit in it, or pretty much any movement of the chair. I haven't tried to stop the rattling, but I would have to try and figure out how to remove the arm rests which is more time than I want to spend on a manufacturing issue.Second, this chair's lowest height setting seems fairly tall for someone of my height. I have it at its lowest setting, and my legs are just at the ideal angle to keep my feet flat on the floor. I can tilt the seat angle to help a little, but it's worth mentioning in case you are shorter than me. This could be addressed by placing something on the floor for my feet, but it's not ideal to do so.Finally, the seat cushion has a mesh liner covering it, which means small particles can end up between the seat and the mesh liner. Since I eat at my desk, small food particles can end up in that space. This is a minor issue, since a general sweeping motion with my hand or a towel will eventually catch the particles and send them flying onto the floor.
