How to choose a right ergonomic office chair?

Check out our buying guide for you!

The lumbar support automatically adjusts as you lean back, which I found helpful, and the wheelbase is solid metal, not nylon, so there is less chance of it coming loose over time.

The netting material makes the chair comfortable on hot days, durable, and able to withstand extended use. And the upshot is a light and relatively compact seat, making it ideal for home office use.

The seat pan of the Doro C300 has a waterfall-shaped seat, which is designed to “offer a weightless seating experience”, closely resembles the one found on the much more expensive chair.

    Excellent, sleek, ergonomic office chair at this price point. The mesh factor (vs other chair materials) makes a world of difference. Very comfortable and breathable, especially when working long desk job hours. Appreciate the many options for adjustability as well, all positions are addressed. Needed to contact Customer Support for a minor issue and they were very prompt and helpful, thank you! Overall great chair!

    I had a shack chair that I paid over $500 for it was good but it was too big for me I have to work 12-hour shifts most of which unfortunately I sit on my rear end I bought this based on some research. This chair is pretty amazing it was very easy to assemble I did it myself in less than an hour. So far no neck or back pain this week or last. I love all the adjustments on the arms it makes things so much easier. Great chair

    In my opinion, the chair is designed for working rather than gaming. It doesn't offer you a feeling on but makes you feel better when working on the table for a long time. It has a discontinuity point between shouder and lumber. Some people will think it is uncomfortable, but it helps your sacral bone in right position that prevent low back pain.

    While the chair didn't end up being a great fit for my long legs(I'm 6'1), the customer service team at SIHOO went above and beyond to try and remedy the issue. If you have any questions or concerns reach out to them via email and they'll give prompt replies and do what they can to address your questions.

    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…
