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

    The chair is easy to assemble and very sturdy (great quality). One of the wheels broke after 3 days of use, but I contacted Sihoo through their official website, and they quickly shipped 2 replacements. Now it works perfectly! I would recommend it to anyone who is short and lightweight. I am 5 feet 4 inches and 108 pounds, and it fits me well.

    I have been using the SIHOO A3 ergonomic chair for a while now, and I have to say it is a game-changer for anyone who spends long hours at a desk. The chair is designed with comfort and adjustability in mind, and it truly delivers on both fronts. I spend 8 hours a day working from home, and this is a perfect fit.

    I recently got my Doro-C300 chair in, very easy to put together the instructions were very simple! The chair feels amazing and breathes instead of those uncomfortable leather gaming chairs. Only thing I personally think the chair could improve on is a sliding seat and locking arm rest! Other than that you guys did a great job! Would highly recommend if you are not trying to break the bank for a crazy expensive chair!
