    • Great Chair
I wanted to get my spouse a nice office chair for reasonable price. I have used Herman Miller chairs at work and wanted comparable features. This actually has a bit more- like a depth adjustment. Nice width, very sturdy. Easy assembly. When my chair wears out, we will be getting another one of these. ... show more

This chair has some great features, such as chair back height adjustment, seat slide adjustment, tilt/lock, and adjustable padded arm rests. It arrived very quick but seemed to be lacking in the packaging. It was as if the parts were just dumped in the box. There was also some surface rust on the thick metal tab on the backrest base, that connects to the seat (see photos). Not sure what this particular chair had been through before getting to me. Still, the rust came off easy with a Scotchbrite pad. No big deal. It would have be nice if the arm rests would adjust down just a little further, which may be an issue for shorter people. It was super easy to assemble and all the parts seemed very sturdy. I did replace the wheels with rollerblade style wheels (for hardwood floor). I did have an issue right off after assembling the chair. When tilting the backrest, it was catching somewhere internally (in the seat chamber), and hanging up. Holding the tilt lever forward with some force would prevent the catching/popping. After moving the cable around that controls it, I realized it would stop hanging up if the cable was in a certain position. So I used a velcro strap to secure it in that position, and sure enough it worked fine (see photo). Evidently the control cable has an issue internally in the chair seat, causing the tilt to hang up. Since I was able to fix the issue easily, I decided not to return. The chair works great now. Still, a bit annoying for a $400 chair. In conclusion, I would recommend the chair. It seems very sturdy and should last a long time. We'll see! ... show more

    • A great chair that requires a "breaking-in" period.
I'm just nearing the 1-month mark of owning this chair and I have to say that this is a pretty comfortable chair. What really attracted me to it were the number of adjustments it had as well as its discrete design. I am at my desk for pretty much all day up until late at night, going from working at home to gaming; so having something that allows to me sit comfortably was really important to me. This chair has satisfied all my needs but there are a couple of caveats that ought to be considered. 1) During the first couple weeks of using this chair, I found that the front pad that supports underneath your knee was actually too stiff to where it would actually be uncomfortable to sit after a few hours. Keep in mind that I'm 5'7" and even with my chair height properly adjusted, the pad was still too firm and uncomfortable. At first, I thought I was going to have to return it but I decided to give it a bit more time for it to "break in". By the third week, the pad finally "broke in" and now the chair is much more comfortable to sit in. If you are considering to get this chair, do keep this in mind as everyone has a different preferences and body types. 2) By pure preference, I opted to remove the armrests as I like to have my forearms resting on my desk. I found that the length of the armrests allowed me to only get so close to my desk that only my wrists could reach the edge of the desk. However, if you prefer to use the armrests, they are pretty comfort and provide good support. They have a rather soft padding and they don't cut off any circulation. While they do have a pivoting adjustment, I found that they were actually a bit too easy to move at times and there is no locking mechanism to keep them in place. Also, if you are like me and like to sit cross-legged, having the armrests installed still allowed me to do that with ease (again, it should be noted that I'm 5'7"). 3) The build process was pretty easy to follow and rather standard with most office chairs. As far as the build quality is concerned, it's really nice. For the price, you get a nice nylon mesh that supports the back and the seat. While most of the chair is made from plastic, there are metal components for the adjustment points that also add a nice color accent. ... show more

**Updated review*** post tirelessly searching for a chair I finally decided on this one because of reviews. I would have preferred the cushioned seat model but not for the price! Shipping-I received the day after I ordered! Chair hugs my body nice. Two things I am really disappointed by 1) is the slight give in the back rest in lock position which prevents your back from being straight which is a feature I prefer. 2) the mesh on the back, towards lumbar is not taut. I feel it should not look like that and that this could be taking away from Back support. Any feedback on that would be appreciated but it is definitely going to be a call to the manufacturer. Overall decent chair however, I did not get the immediate relief or that ah ha moment that I was looking for with this chair. 3/5/23 updated review-- this chair is by far worth the money I paid for it! 1) slight give in the back support took some getting use to but studies show it takes pressure off of your spine. 2) mesh on the back of chair seriously not a big deal that I wrote about previously. The chair is sturdy and the mesh on this chair is top of the line and offers a lot of support.m and comfort. I work from home and sit in this chair 8-9hours a day. I have a Hx of tailbone pain from sitting in desk chairs but not with this chair. The only thing is my bottom gets a little cold but a $5 chair cover solved that problem but it's better than swap butt. I am very very happy with this chair. Only feature I wish it had is if the arm rests slid forward and backward. Everything else about I love and most important it is comfortable for a long day of tasking! Give it a try you will not be disappointed ... show more

    • Really Good Chair, but Overpriced
I just bought two of these chairs for $380 about two weeks ago. I thought 380 was a little expensive for these chairs but I just checked again and they just jacked the price up another hundred bucks too. Damn near $500. It’s a nice chair, but it is NOT a $500 chair. $300 would be a better price point when you compare the quality of the chair. ... show more
