Review: Comfortable and accommodating for the price - 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.
Review: VERY PLEASED; Comfortable with many adjustments - I have a NOUHAUS Ergo3D Ergonomic Office Chair that purchased on desertcart 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

### ⭐⭐⭐⭐⭐ Do not miss
*by C***G on September 7, 2023*

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.
