My wife bought this for me because I started working from home. My back was killing me from sitting in a regular chair. But this chair has all of the adjustments you need to feel comfortable. It did not come with instructions but it's very simple to construct (plus I've assemble office chairs before). It came with extra hardware which was nice. Everything is made out of plastic so if you are a heavier person, sit yourself down lightly, or get a chair made with more metal. Still feels solid enough for plastic though. 10/10 would buy again even if it breaks.

Great office chair... Due to the pandemic I sit in my office far more than traveling to see customers these days. This chair has been great to keep my back from hurting. The main reason that I got it though was that it was that it was TONS cooler that my old executive leather chair. My office is unfortubately in the hottest room in the house direct westward facing and it makes a huge difference to me. The only thing I don't care for too much is the design of the head rest. I will probably be contacting the company to get another one as my current one has broken at the point of adjustment and will slide down occasionally when I lean back. All in all it is definitely a fantastic product.

I hate using Allen wrenches!!!! Four stars for having to use the short, tiny one that was included in order to put this together!! Yes, there were curse words used while assembling this chair! Okay, so that's the negative. I love this chair! It is very, very comfortable and I do not hurt anywhere after sitting in it for several hours. I didn't install the headrest because I'm short and don't actually need it. Overall, I highly recommend this chair! Not the Allen wrench. Just the chair.

The chair is great. The instructions on how to put it together were terrible and hardware was mixed together. The instructions relied on pictures and sketches. As an example, to install the arm rests properly, from the pictures you had to figure out that the front of the armrest was a little thinner than the back. It would have been easy to install backwards. The hardware was mixed tohether in 3 pouches. There were two different washers in the same bag. They had the same external diameter, but the hole dad different diameters. I had to figure out which washers went where. They provided white cotton gloves because the bolts and washers were covered with machine oil. It was a mess!
This is a super comfy chair for a short person. I'm only 5'3" and the seat can get low enough to the floor to be comfortable for me and the angle of the back, height of the arm rests, and length/angle of the foot rest are all easy to adjust to be just right. My favorite thing about the chair are that I can completely stretch my legs out using the foot rest, or I can also sit cross legged in the wide seat and not even hit the arms at all. I also like the bouncy mesh back- very comfy. One thing buyers should know though is that the back and foot rest don't flip out automatically when you lean back like they would in a lazy boy recliner. (For some reason that's what I thought they would do.) However, this chair is very comfy and it was really easy to assemble - just a ... MoreThis is a super comfy chair for a short person.

I thought this chair was worth every penny.
This chair meets all my criteria for the best desk chair. Assembly was easy and quick. It's mesh so no more sweaty thighs, swivels smoothly and glides over carpet effortlessly. The headrest is great and I'm now getting used to it. The height adjustable arm rests were great and moves up and down no problem. It seems durable but time will tell. Solid purchase and 100% will recommend to anyone!
I have been searching for a chair for my home desk for about 3 months now. This was my third one and it was worth it! Ergonomic mesh chairs are hard to find under $300. The ones under $300 have terrible reviews. This chair is affordable (less than $200 was my goal) and seems to be made of quality material. So far, I've had no stretching of the mesh (this was a huge problem on reviews for other chairs) and that adjustability makes this chair great for different needs. I have found even if the chair is not tall enough to have proper typing stance (elbows 90 degrees or slightly more open), the armrests can be raised so you're able to have your elbows above the keyboard. The standard recline of the chair is nice -- not too far back, but it is adjustable if you want more ... MoreI have been searching for a chair for my home desk for about 3 months now.

The standard recline of the chair is nice -- not too far back, but it is adjustable if you want more of a recline. My biggest complaint is that the lumbar support does not actually touch your back (at least for me weighing less than 150lbs). You have to apply quite a bit of pressure to feel that support bar, but the mesh isn't too loose so this isn't a huge problem. At full height of chair, anybody 5'6 or less should get a foot rest for proper posture. Overall, great chair and so glad I found it.
Preface: I'm 330lbs (the very top of the weight limit for this chair) and this chair is good. I didnt expect Herman Miller quality for $150. It would be 5 stars if not for the super cheap casters & bad instructions*(see below). It was easy to assemble until I got to the headrest. Both the YouTube video and instructions didn't make any mention of the 2 white plastic tabs needed to make the headrest adjustable. In case you find yourself in this position you have to insert the headrest into the black plastic coat hanger about halfway, THEN clasp the plastic pieces around the headrest support, THEN afix the bottom piece, THEN start the screws holding it together (only start the screws because it has to be fitted to the top of the seat before its completely screwed ... MorePreface: I'm 330lbs (the very top of the weight limit for this chair) and this chair is good.

This small bit really made the assembly unnecessarily bothersome. All that aside I did swap the wheels with better "rollerblade" style ones and all in all this chair does the job comfortably, without creaking noises. I wouldn't let the headrest instructions deter you from buying and otherwise great chair. Particularly if your a big person like myself. This is a really good chair.
Shoutout for the perfect ergonomic desk chair! I've been looking for some new additions to add to my office space! My brown leather chair wasn't cutting it for back support and this looked like the perfect solution. The only thing I wish was a little bit heavier is the wheel base. Everything about this chair is sturdy, but if you lean far enough backwards, you could potentially flip over. More expensive brands have a base that weighs a ton to keep the chair grounded. Other than that, I love this chair and I'm so happy to have it in my new space. Constructing it took no time at all!
I'm working on it. Instructions seem clear. I'm not sure all of the screws are seating correctly, but I will work on them. They seem to thread at a slight angle, one or two. I was pleased to see the chair base has five casters, since the photo shows only four. I expect to use this for many years, so I hope all goes well. Basically, seem high quality and well designed.
