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 bought the SHIOO DORO C300 ergonomic office chair a month ago, and I have to say that I am very satisfied with it. It is one of the most comfortable and supportive chairs that I have ever used. Here are some of the features that I like about this chair: • The ultra soft 3D armrests are adjustable in height, and angle, so I can find the best position for my arms and shoulders. They are also padded with high-density foam, which feels very soft and cozy. • The dynamic lumbar support is a unique feature that automatically adapts to my posture and movements, providing optimal support for my lower back. It helps me maintain a healthy spine alignment and prevent back pain. • The seat cushion is made of breathable mesh fabric, which keeps me cool and dry even after long hours of sitting. It is also contoured to fit my body shape, and has a waterfall edge that reduces pressure on my legs. • The chair has a sturdy and stable base, with five smooth-rolling casters that can move on any surface. It also has a pneumatic height adjustment lever that lets me easily raise or lower the seat. Overall, I think the SHIOO DORO C300 ergonomic office chair is a great product that offers excellent value for money. It is well-designed, well-made, and well-functioning. It has improved my sitting experience and productivity at work. I would highly recommend it to anyone who is looking for a comfortable and ergonomic office chair.

Some reviews complain about the assembly, and I imagine this is due to the chair's many parts and many screws. For example, the base of the chair has six parts, not including the wheels: a center piece, and five legs, each leg attached to the center piece with two screws. I've had other (cheaper, weaker) chairs where this is delivered as a single complete piece, or as pieces that slot together without screws. Each arm also has four screws - two attaching the separate pieces of the arm, and then two more to attach it to the seat. The design is also generous with spacers to support the screws - the arms have five spacers each. However, the single most annoying part of assembling an office is attaching the back to the seat. Generally the attachment is purely with screws, so you have to fully hold two heavy objects close together in an awkward way while you get the screws in. I've done this many times with many chairs and it's always been a massive dreaded pain. This chair's different: the back slides onto a mount attached to the seat, and then, although it still isn't stable without screws, all you have to do is support it while you insert the screws. By reducing the difficulty of the SINGLE worst part of office chair assembly, this chair absolutely doesn't deserve any complaints about its assembly. For the comfort and ergonomics, I only have one complaint: the arm rotation is adjustable and I have no use for that feature and only ever activate it unintentionally. This chair has a single control for the gas cylinder where a chair five times its price would have three other controls and position locks. Depending on your body type you might not find the dynamic lumbar support comfortable, but for me it's a very nice chair.

I have a NOUHAUS Ergo3D Ergonomic Office Chair that purchased on Amazon 5 years ago that is good but wanted to step up and this chair is terrific as far as adjustments and lumbar support, neck wrest. Found the chair very comfortable. I was surprised how easy to put together. About an hour and cup of coffee. Saw reviews on difficult to assemble, those people must be challenged on anything past changing a light bulb. Only this I don't like is arm wrests move much more freely then I would like. After using chair for four months, I change rating from 5 star to one star. The chair is still comfortable but armrest are getting looser and looser to the point I am going to have to glue in place
