I have personally researched several office chairs before deciding on this specific chair. I was really mixed with the reviews that many have left about this chair. I had to remember that many people are quick to give a bad review and slow to give a good one. I am very happy that I gave this chair a try because it has already impressed me in several ways. With my previous chair, I could not sit in for long periods of time without back pain. I have been able to sit in this chair for 8 hours, without any pain at all. I will update my review after some time has passed and it is used more. There are 3 of us that have tested this chair in the few days I have had it. Me (5’8”, 175 lbs), my husband (6’1”, 295 lbs.), and my son (5’8” 150 lbs.) I will cover some of the points, as I noticed these were mentioned in the reviews. 1. If you are tall, you don’t need to look for a different chair. Some complaints I read were about the size of the chair. The seating area is not smaller than most chairs. In fact, it was several inches wider than my previous chair and others I have in my home. The length of the chair seat from the back to the front is also a few inches bigger. My husband is not a small man and he felt comfortable in this chair. Everyone was able to adjust the height of the chair to have our feet flat on the floor. 2. I currently am a college student online for graphic arts. I always sit at my desk with homework or drawing. My previous chair was worn out and I often put pillows on my chair for padding or to support my lower back. The lumbar support with this chair is perfect for me. It has been mentioned in other reviews that this lumbar support is not a benefit for them, and it is rather awkward. The chair is not the issue, it is more of the way a person sits in the chair. This has been a learning process for me, as I want to slouch over my desk. If you will pull the chair closer to the desk, you will feel the support from the lumbar system. It is a small area of the chair that pivots when you move. 3. The chair gives me great comfort when I am sitting in it. The padding is nice, and the back of the chair gives me support when I lean back. There is a lever that allows the back of the chair to stay in place, which I do not use. There is a tension adjuster under the seat that will allow you to adjust the resistance of the chair leaning back. 4. The lumbar support is not something well explained in the description. I really wasn’t sure what I was getting myself into. It does not push up against your back, it gives only slight support to your back when you lean forward. The seat does angle slightly down, but I do not feel as though I am falling out of my chair. Again, I feel some reviews here are simply people that are not properly sitting in the chair. I do agree with some reviews and wish it did offer more support. Maybe the lumbar pillow should be larger or pivots further into a forward motion. Good Points: The chair is comfortable and provides ample padding. I like the smooth rolling of the chair. I totally like the lumbar support, it pivots very well to adjust to your movements. I personally didn’t find the chair to be difficult for height and keeping my feet flat on the floor. It was easy to assemble, everything had a letter or number and simple steps to complete. Assembly took a very short amount of time and I was able to do it myself. Bad Points: The lumbar support does take some adjusting to get max benefits from it. I would like to see the base of the chair be constructed of metal or better materials. The arms of the chair could use some work. The pushbuttons to change the height can be tricky based upon where the arms are fixed to the chair. I also do not like the push buttons on the outside, as they can easily be pressed by animals rubbing against them or small children in the home. The arms also have a weird position. When you attach them, there is a cut out on the bracket, as though they are adjustable to position where you need them. It didn’t work for me, as they would not adjust the arms in, just allowed you to adjust them out further from the seat edges. Where improvements could be made: The arms of the chair would be better if you could pull them up and out of the way. Make the arms of the chair more adjustable, where you can have them closer to the seating area, not further. Allow adjustment for the lumbar pivot to come forward more. Change the base of the chair because the faux metal covering on the plastic makes the chair look cheap. I also do not prefer the white stitching on the chair. It would be nice to have the option of black stitching. I give this chair 5 stars because it is the most comfortable chair that I have owned in years. The padding is enough to give comfort, but not over-padded to make it bulky.
