Sihoo Doro C300 Ergonomic Office Chair with Headrest, Lumbar Support, Adjustable Backrest, 3D Armrests, Breathable Mesh, Height & Tilt Adjustment - Black

The package was well packed with care. Everything in the box was labeled clearly to understand for assembly easily. I'm unsure if this was designed or made in Japan, but messages were written in Japanese. It was committed to quality service messages and customer service instruction. The tool came with the part is unlike any other, and I will be keeping this in my tool box. As for the chair, I feel very comfortable and low enough for 5.3 to rest on it. Both armrests lift up and hold until they pull down. I had to put some pads on the armrest as it does not have them. I used memory foam and wrapped it with a cute self-adhesive bandage, as I had no time or money to get customized padding. I am a full-time worker and full-time student, so I spend most of my days in the chair. Anti-blue light eyeglasses and this chair made my work efficient and fewer headaches!

The chair arrived earlier than we expected, and in great shape, so that's a plus. The directions were easy to follow. There were extra screws/bolts for every step, and it went together without a problem. The chair seems sturdy, but it is somewhat smaller than expected. I am 5' 10", and the seat ends mid-thigh for me. Also, the arm rests were short for me. My wife is 4' 11", and the chair's dimensions were perfect for her use. It was intended for her, so this worked out perfectly. She has only used it a week so far, but she claims it is comfortable, and believes it will last. I would recommend this computer chair to anyone based on design and quality, but suggest it for smaller framed people.

Excellent quality. Love the adjustable features, colour and design.

nice chair easy to put together good price made a good christmas present

I like this chair. Comfy and sturdy

Very comfortable chair .....

I work remotely full time and spend around 9 hours a day at my desk. Before buying the C300, I was constantly shifting around trying to get comfortable. After about two weeks with this chair, I noticed I could focus longer without thinking about my back or shoulders all day. The mesh seat stays cool, even during warmer afternoons, and the reclining tension feels smooth instead of stiff or jerky. Assembly took me about 50 minutes alone. The instructions were mostly clear, although attaching the backrest would definitely be easier with a second person. Overall, this is the first office chair I have owned that actually feels designed for long work sessions instead of just looking ergonomic.

The chair was difficult to assemble at first but you just have to put a lot of pressure on the screws when putting them in. The chair is very sturdy and comfortable. I would recommend it to anyone!

The lack of tilt for the seatback was a deal breaker. I am recovering from fractured vertebrae. Fine for most people..

Overall a solid ergonomic chair — comfortable, well-built, and the adjustability is genuinely useful. However, the armrest locking mechanism is defective. When extending the armrests, they inconsistently fail to lock into position. Sometimes they lock fine, other times they don't catch at all. This is a consistent issue, not a one-off. Currently in contact with Sihoo support for a replacement. Good chair otherwise, but a frustrating defect on a component you use every day.
