The ofice chair is comfortable and ajustable. I like that the chair contins no wood therefore I belive it will be more durable and last longer. I bought one for my office and was so happy with it I had to buy another one.

I purchased (2) SIHOO Doro C300 Ergonomic Office Chairs in February 2024. These chairs are extremely comfortable and very easy to assemble. We have had absolutely NO issues with the quality or appearance of these office chairs. We currently have a total of (4) of these office chairs in our small office. I asked around before posting this review and everyone in the office gave these chairs a thumbs up. We may be purchasing these again once our staff increases.

Got the chair today and put it together. Seems like a good, sturdy chair so I’m giving it a 4 and not taking points off for how uncomfortable it is for me. This chair has zero mid-back support. The lumbar support juts out way too far to even lean my mid back into the chair. Head rest pushes too far forward. If I keep the chair I’ll probably take the head rest off. Not enough adjustment in the lumbar area to adequately fit my 6’2” frame. The arm rests are too wide so have to keep them turned all the way in to make it comfortable to type on my computer. The arm rests also shift forward and back too easily so any time I hold them to adjust myself in the chair I have to push them back into place. The chair was relatively easy to put together. I weigh 145lbs and the webbing of the seat seems pretty sturdy, too. I may get a mid back pillow and try to keep it or I may give it to my husband. Kind of disappointed but that’s what you get for buying a chair off the internet and hoping it will help with your scoliosis. Heavy and sturdy, like I said. Looks really nice. I’m just not sure if I can keep it.

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.

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.

I wanted to give this a few months before giving a review. This chair is simply amazing. I'm a large man, so I had to take the side handles off(super easy to leave off). No weird cramping or back problems anymore. I sit in it for at least 6 hours a day

I personally think one chair is hard to meet everyone's tastes. I bought this chair for my family member and he loves it and feels very comfortable. He has a moderate body figure with height about 5ft 8in. However, this chair is a bit large for me to sit in as I'm short. Overall, I'm satisfied with this purchase.
