Doro C300 Ergonomic Office Chair with Ultra Soft 3D Armrests | Dynamic Lumbar Support for Home Office Chair, Adjustable Backrest Desk Chair, Swivel Big & Tall Computer Chair, Black

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!

Very comfortable, easy to assemble, and highly adjustable. Great back support for long hours of work and gaming. The build quality feels premium, and the chair is sturdy and supportive. Definitely worth the price and highly recommended.

I like this chair, but I’m disappointed by SIHOO’s misleading marketing approach. My friends and I have used SIHOO chairs in China for years, trusting them for cost-effectiveness and quality. When we come to US, we naturally choose SIHOO again. To my surprise, the overseas C300 model severely compromises the brand’s value. Before buying, we noticed that overseas versions (like the S100 and C300) lack a footrest found in the Chinese versions, but we didn’t know why. Once I received the C300, I still found it comfortable and well-built. However, after reading more on Chinese review videos, I realized the overseas C300 is essentially a downgraded product that conflicts with the SIHOO Doro series’ original concept. Key differences: 1. The original version uses a gravity-sensitive tilt mechanism with wire controls, while the overseas version uses simpler pole controls. 2. The original has a seat-depth adjustment feature, but the overseas version does not. 3. The tilt angle advertised in Chinese official website is 95°–145°, while the English site states 92°–112°, and 110°–130° on Amazon. This discrepancy suggests an inferior tilt mechanism. 4. The base is downgraded from a single integrated unit to five separate pieces. In China, the original costs about $220–$250 with free on-site installation — a product more comparable to the $400 overseas C300 Pro (2024.12.8), which offers flip-up armrests and adjustable seat depth, though it remains inferior to the original C300 in terms of tilt mechanism and base. Why did I keep digging reviews after receiving a decent chair? Because the manual doesn't include Chinese, even though it provides English, German, French, Italian, Spanish, Japanese and Arabic! I feel misled by the identical product name. Although regional differences are understandable, the abundance of information on Chinese Internet set my expectations too high. If I had known the overseas C300 was so different, I would have chosen the C300 Pro instead. When considering only the overseas versions, I can hardly recommend SIHOO chairs to my friends because, despite also being made in China, I have no idea where the overseas versions' factory is, what the cost and workmanship are like, so I can't judge the cost-effectiveness. In terms of C300 quality alone, I am 5'6" tall and weigh 155 pounds, and the size of this chair suits me well, with good attention to detail in workmanship. Update on 2024 Dec 28: According to information from the Sihoo customer service team, the C300 model in the US is actually the C100 in China (and it seems to be the C100 Gen 1 instead of Gen 2). And they said they will make certain improvements to some issues mentioned above. In view of the long long email conversations, I believe Sihoo's customer service department treated with their products with care, so I changed the rating.

I was searching for a chair that would be comfortable for working throughout the day. I also wanted a chair that was sturdy as I use my chair 6 to 10 hours a day. I didn't want reliability to be an issue. After searching and narrowing it down, I chose SIHOO Doro C300 Ergonomic Office Chair. I like the look of the chair and the price was in my range. I like that it's mesh because I don't feel warm in the chair after using it an extended amount of time. I must admit, it took me some time to get used sitting on mesh, my other chairs have had mesh backs but had some other sort of padding for the seat. I like the adjustability of the chair. That too takes some getting used to, but once you do, I'm sure you'll enjoy the chair as well. Construction of the chair was pretty straight forward. It took me about 30 minutes. I had to have my wife assist with attaching the armrests, but other than that, no fuss no muss. One day, I discovered that my headrest bolt cover was missing. I decided to reach out to Sihoo to see if I could purchase a replacement. They responded quickly and handled the situation quickly. I was very pleased with their customer service. They didn't have the part readily available, but they had it shipped to me from China. I thought it would take forever to receive, but I got it within a week. They did this with no cost to me. I've had the chair for a little over three months and I've really enjoyed the chair. I don't regret this purchase and have been enjoying my chair.

DON'T BUY THIS CHAIR! Ordered this chair due to the great reviews. This chair came in 100000 pieces and you need to assemble it for an hour or two. After assembling this chair I was ready to love this chair. But sitting on this chair longer than 1 hour hurts my legs, the angle of the seat feels uncomfortable and additionally the headpiece is broken and slips down. I thought it would be no problem returning the chair. BUT you need to pay for the transport which would be over 100$! I will need to sell it privately now and will need to buy from now on all furniture pieces in a regular furniture store where I can try out the furniture before purchasing. Absolutely annoying!

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.

This chair is EXACTLY what I have been looking for. The comfortability, sturdiness, and how far back it reclines is by far the best I have experienced. I highly recommend this chair! The color is black and looks nice, the mobility is very easy and smooth.

It feels sturdy and well supported when seated. Especially appreciate the lower back and neck support. The lower back support is angled ergonomically so that a push can be felt as the body leans back. The neck support is highly adjustable that it almost guarantees a comfortable setting for different postures and body types. The other parts worth mentioning are foot rest and arm rests. The foot rest has 15kg weight limit as labeled, but should be good enough for normal use. When the foot rest is fully extended out with maximum recline of the seat back, it works as a solid lounge chair substitute. Arm rests are insanely adjustable too. In fact, they are the most versatile ones I have ever seen. I used to spent lengthy time on a Herman Miller Cosm. Its build quality and material feel are better than this Sihoo, but this one offers more seating comfort and functionality. Considering the price difference, it will be hard not to recommend this one.

Après + d'un ans d'utilisation, je conseille cette chaise. Je suis totalement en télétravail et j'ai developé des douleur sur mon dos. J'ai acheté cette chaise ergonomique après avoir passé des heures à chercher une solution pour soulager mon dos pendant mes longues journées de travail. Je suis bluffé par son confort et son design ! Le dossier épouse parfaitement la courbe de mon dos, et le soutien lombaire est ajustable, ce qui me permet de l'adapter exactement à ma morphologie. Les accoudoirs sont bien rembourrés et réglables, un vrai plus pour éviter la fatigue des bras. Mention spéciale pour l'assise, ferme mais confortable, qui me permet de rester assis sans douleur pendant des heures. Le montage était simple et rapide grâce aux instructions claires, et les matériaux respirent la qualité. C'est un investissement que je ne regrette pas du tout. Je recommande cette chaise à tous ceux qui cherchent à allier confort, style et ergonomie !

Perfect and easy to fix

Elle est jolie, confortable et facile à monter.

Sitsen är aningen för smal för bästa komfort, men i övrigt en bra produkt till ett lagom pris. Monteringen tog ca 1 timme inklusive ergonomisk anpassning av ryggstöd, nackstöd och handledsstöd.

I've needed a better office chair since working from home during lockdown showed me how inadequate my last chair was. To be honest you can pay eye watering prices for a decent chair with good back support so I really had to do some digging to get a good deal. This chair ticks all the boxes. It's comfortable, supports my lower back and is easy to adjust. It is a well made, solid piece of furniture so it does take a bit of effort to put together but the instructions are clear, all the necessary screws are provided as are the tools. Really please with this purchase!
