  • Champagne Taste on a Spiked Seltzer Budget? Buy This Office Chair!
Color: Black Style: Ergonomic office chair
This office chair is a great alternative to those that cost hundreds more, even in the pre-owned/secondhand marketplace. The value for the price paid is great because of its build quality, ease of use, good ergonomics, and overall aesthetic. I spent a good amount of time weighing my options of a used Herman Miller or this and I'm so glad I chose the SIHOO. It's nice to have something new of your own and to get a good deal on something. The ability to customize arm height and angle, headrest support, and seat height for a reasonable price were all important factors in the decision. Materials were too, and the webbing on this chair is very durable. The lumbar support is also a huge benefit. The tilt range is also very generous. Assembly took me 40 minutes, but I was half watching a preseason football game at the time. With proper focus, I think 30-35 minutes is reasonable. The chair was very well packed, with strong cardboard inserts, plastic wrapping, and extra hardware just in case. The required tools are provided and the gloves were a nice touch (they can be used for the gas lift; I didn't need them). One recommended upgrade: rollerblade wheels. They make the chair perform at its best, especially on a glass mat. Ultimately, this chair took my work from home setup from a solid B to an A. ... show more

After spending countless hours at my desk, I finally found the perfect companion for my workday - the SIHOO Doro C300 Ergonomic Office Chair. It’s not just a chair; it’s a game-changer. From the moment I sat down, the difference was clear. The ultra-soft 3D armrests cradle my arms like a gentle cloud, reducing fatigue during those long coding sessions. The chair’s design is not only sleek and modern but also intelligently contoured to support the natural curve of my spine. The adjustments are intuitive and plentiful, allowing me to tailor the fit to my body’s needs. Whether I’m leaning back to contemplate a problem or sitting up to focus, the chair moves with me, offering consistent support. The robust construction assures me that it’s a lasting investment. Plus, the easy assembly meant I went from unboxing to relaxing in no time. In my extensive experience with office chairs, the SIHOO Doro C300 stands out for its dedication to comfort, ergonomics, and quality. It’s an absolute must-have for anyone serious about their office setup. Five stars aren’t enough to capture the sheer excellence of this chair! ... show more

  • Comfortable and accommodating for the price
Color: Black Style: Ergonomic office chair
I've used this chair for 3 months now, and I have zero regrets! I purchased this chair on sale, but the chair feels worth their original listed price. The mesh material has a nice, bouncy give to it that feels very comfortable when sitting. The mesh has a strategically used rubber texture that gives it some grab and prevents a sliding feeling when leaning. The plastic skelatal structure feels high-quality, and the base of the chair feels weighty and well built. The lean-back position on the chair feels great too. I haven't found a way to tilt the chair, but the lean-back feature and the shape of the base has made that a non-issue. I also haven't figured out if there is a way to further customize the lumbar support, but it feels adequitly placed and pronounced by default. A great feature of it is that it slides and automatically readjusts to your back when leaning. The entire backing of the chair can be raised or lowered as one piece. The highly customizable headrest was a selling point for me and I am VERY pleased with it. It can ARCH forward or back at multiple positions, TILT foward or back and pultiple positions, and SLIDE up or down in multiple positions. I can get it to the perfect position on my neck and get perfect head-support! The 5 metal legs and plasic rollers feel heavy and strong. The arms are adequit. They can't hug closer to your body, and the material on the armrests feel a little more stiff and frictiony than I might have originally perfered, but they feel like they will last. They may not have the pitch and extra customizability of a more expensive chairs' armrests, but they can slide forward and back and they have a large degree of rotation. I have been able to leavearge the rotation abilities offered, piared with the shape of the armrest, to find a comfortable position regardless of my various uses/needs. All-in-all, I feel it is a fantastic chair for the price and I highly reccomend it! (If Sihoo is reading this, I wish I could add-on a moderately priced, attachable footrest to this chair. 😉) End of novel. ... show more

  • Extremely uncomfortable!!
Color: Black Style: Ergonomic office chair
This is the most unforgiving, uncomfortable office/desk chair I have ever had the displeasure of sitting in. I could only sit in this chair about 20 minutes at a time when it first arrived due to tailbone and lower back pain. I purchased two different cushions to sit on in the chair and can now sit about 35 minutes before the tailbone and lower back pain is so bad I must get out of the chair. I work from home, 8 hours per day, and sit and stand intermittently throughout the day. Unfortunately I did not keep the box the chair arrived in or I would have disassembled it and returned the chair. I purchased this chair based on the reviews and statements that the chair was ergonomic in design and comfortable. I applaud whoever is able to sit comfortably in this chair for any length of time. I have wondered, are the reviews fake? Staged? My old chair I was planning to get rid of is more comfortable than this one. I have bought a new standing desk, monitors, monitor and laptop holders to improve my productivity and comfort. Then there is “the chair”. The purchase of this chair was the last of the money I had to revamp my office so I guess I am stuck with it. After reading this review and you still plan to order this chair, please keep the box and take pictures of all the parts in the box before removing each piece to get it back in the box if you need to return it. It took about 45 minutes to put together. Thank you for your time. ... show more
