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

I don’t usually write reviews unless a product really stands out, and after using this chair for the past six months, I can confidently say it deserves recognition. If you're on the fence about this purchase, let me help you out: this chair is well worth it.Let’s start with comfort, which is probably the most important factor when buying a chair—especially if you're using it for work, long gaming sessions, or extended periods of sitting in general. From day one, this chair has been extremely comfortable. The cushioning is just right—not too soft, not too firm—and it provides great support without causing fatigue, even after hours of use. I’ve had chairs in the past that felt good initially but broke down quickly. Six months in, the comfort level hasn’t changed at all. The padding is still holding its shape beautifully, and the back support continues to make a noticeable difference in my posture and overall sitting experience.Now, let’s talk about what really sets this chair apart: the fabric. I can’t overstate how impressed I am with the quality and feel of the material. It has a smooth, durable texture that feels premium to the touch and is noticeably more breathable than other upholstered chairs I’ve owned. Living in a warmer climate, I really appreciate how it doesn’t trap heat or become uncomfortable over time. The stitching is also excellent—no loose threads, no fraying, and it’s held up flawlessly with daily use.What really reassures me about this purchase is that after half a year of use, the fabric still looks brand new. No pilling, no sagging, and no signs of wear. I’ve even had a couple of accidental spills, and they were easy to clean up with no staining. It speaks volumes about the durability and quality of materials used in this chair.Assembly was straightforward and didn’t take very long. All the parts were clearly labeled, and the instructions were easy to follow. The build feels sturdy and well-engineered—no wobbling or creaking when you shift positions. The casters roll smoothly, and the height adjustments work perfectly.If you’re someone who spends a lot of time sitting—whether working from home, gaming, or just relaxing—this chair is a solid investment. It looks great, feels fantastic, and is clearly built to last. I especially recommend it to anyone who values high-quality fabric and long-lasting comfort in their seating.In a market flooded with overpriced and underperforming chairs, this one stands out as both affordable and high quality. Six months in, I’m just as happy with it as I was on day one—maybe even more so.Highly recommended!

The office chair feels incredibly comfortable with its ultra-soft 3D armrests and dynamic lumbar support. After using it for long hours, I noticed a significant reduction in back pain, which was a game-changer for me. The chair's design is sleek and easy to put together, and it's holding up really well over time. I love how adjustable it is, especially the 2-way headrest and the height settings, making it super customizable to my needs. Overall, it’s definitely a great value for the price!

I really like this chair—it’s comfortable, supportive, and looks great in my home office. The dynamic lumbar support makes a big difference during long work sessions. The armrests are super soft and adjust easily to fit how I sit. Overall, it’s a solid, well-designed chair that I’d definitely recommend.

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.

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.
