It's so difficult to purchase an office chair through the web because when you're looking for such an item of course you want to SIT in it. That is the number one selling point for an office chair, right. So.... I combed Amazon looking for reviews of exceptional office chairs with features I wanted and a price point I was looking for. This chair had almost everything I was looking for. First, I wanted a mesh back to keep me cooler in my office. This does have that….A nice big back with good support that lands right at shoulder height (I’m 5’7”). However, it is NOT adjustable up and down. It does have lumbar support and that is NOT adjustable either (so sad for this.. this would have been really nice). Next, I wanted a nice wide seat. Got that! Very comfy. I wasn't looking for faux leather but it's very nice. However, I tend to slide out at times. My other chair was cloth and I never noticed or thought of sliding out. Thirdly, I wanted adjustable arms. Got that! You can set them as wide as you'd like WHEN YOU ARE ASSEMBLING! I have them at widest setting. Then you can adjust them up and down for proper arm placement when keyboarding and mousing. Love this. Of course it has height adjustment and tilt back. Lastly the castors are very sturdy and roll nicely.

You must assemble this chair. It comes in a box with all the parts disassembled. The instructions are easy. They use pictures so basically anyone can follow. It looks overwhelming at first but it's not. If you have an electric screw driver you are really good to go but a regular Philips screwdriver and elbow power works too.

To sum up.... I love the chair.... especially for the price point and delivery was quicker than promised. Arrived in two days. I’ve only sat in it for three days. We’ll see how reliable it is as I continue to use it.

I ordered this chair to replace one where the pneumatic height adjustment failed. My 6 foot plus frame weighs a fit 250 pounds, so the chair has a great deal to live up to. The chair went together easily. I chose not to add the arm rests as I roll back and forth between several desks and the chair's arms simply get in the way of reaching for gear/paper off one side or the other. The chair is comfortable and works as advertised. The only fault I find with the chair is a popping noise whenever I lean back. While annoying, I still like the chair.

I bought this as a replacement of an identical model that I purchased in 5 years ago (2010). I have used this chair exclusively, daily; It's literally the only chair I own. It held up like a champ, honestly the best built decently priced chair I have ever owned. After 5 years only two things went wrong was the seat started flaking black pieces of vinyl/plastic off the edge, and the arm rest for my right arm had a crack from where I had rested my elbow.

Differences between the model I bought 5 years ago? The seat is a bit firmer that I remember my other being originally, but in a good way. And the wheels are made of slightly softer and smoother rolling plastic.

Assembly is very easy, 4 screws for each arm rest, 4 for the tilting assembly into the base, and 4 to attach the back. Everything was packaged nicely, wrapped in bubble wrap and seperated by cardboard sheets. Arrived without any damage.

I thought from the reviews this chair would be very comfortable, but I find its just okay. It didn't take too long to put together (about 40 minutes). The back is situated too far back and there's no adjustment to give you lumbar support. It does roll very nice. The arms have some padding. Overall comfort and support for a larger person (259lb) just isn't there. The seat is large enough, but I really need that back/lumbar support.

Chair was easy to assemble, durable, and comfortable. The armrest are a little wobbly at times, I am a larger man, but this chair was able to accommodate me for my daily work routine.

Good buy for the price. The chair is comfortable and well built but I probably wouldn't have bought it if I could have tried it out first. First it is wide, too wide for me. Second the lumbar support is ok but would be better if you could adjust it, primarily up and down rather than tension wise. The faux leather is thin and the back had a small tear (not enough to go through the hassle of sending it back) mostly due to poor packaging by the manufacturer. It also had some rough handling because the box was torn and falling apart. Luckily nothing was missing. I actually modified the chair to make it fit me better. I reversed the arms so they are pointing backwards. This put the arm rest backwards so I reversed them as well. I can live with it for now but I will probably replace it once I get my old chair reupholstered.

I like this chair a lot!! I think this would work well for those 5'8'' and taller. The seat is comfortable, I like that it tilts and has adjustable arm rests. My only problem, which is why I didn't rate it higher, is the back is not adjustable. This chair would be amazing if I could just get the back to go back just a bit. I sit so straight up that it feels awkward. But compared to what I was sitting in before to do my school work, this is a 1000% improvement. I just tilt back when my back feels tired. I'm, also, too lazy to take it apart and return it for something else.
