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.

    After about 1 year of use, the seams on the chair finally gave way and one piece broke. Fortunately, as the product was still under warranty, I contacted support and they quickly returned the faulty part to me.

    Very happy with this chair. It is a great replacement for my Noblechairs Hero, which was too big for me. The chair arrives in packaging that protects the contents very well and comes with everything needed for assembly. It is generally made of good quality plastic and is very well finished. In terms of comfort, it is night and day; this chair is comfortable and ensures a good sitting position with numerous adjustments. A pleasure to use after the Noblechairs.
