Key Features
Dynamic Lumbar Support
Flexible Backrest
Bigger W-Shaped Cushion
Seat depth adjustment
I took the C300 Pro to work, where I sit for eight hours a day. It is way more comfortable than my basic office chair, and its high-tech look gets plenty of attention from everyone else in the office.
Adjustable seat depth for custom comfort
Doro C300 Pro’s expanded seat cushion provides a more spacious seating area for larger individuals, enhancing comfort. The adjustable seat depth allows for personalized positioning to suit your needs.
Adjustable anti-spine lumbar support
The BM (Body Movement) Tracking System ensures the lumbar support automatically conforms to your spine to keep your back comfortable and supported during different postures without the need for manual adjustment.
The mesh fabric provides plenty of support without all of the sweatiness of a leather gaming chair. All of the adjustability options of the C300 Pro allow you to comfortably sit for hours on end while you game away.
How C300 Pro Chair Helps?
Flexible seat back that contours to your back
When you move your upper body around or reach down to the side to pick up a pen you drop, the streamlined backrest with triangular frame flexes and matches your back, providing continuous support.
Full-back comfort for any size
Easily adjust the headrest up and down, back and forth, or rotate it to fit the curve of your neck, giving you the perfect support and comfort. The wide surface also offers enough space to rest your head comfortably on the side.
Designed to elevateyour workspace
Doro C300 Pro features a sleek, modern design inspired by ergonomic human spine. It’s comfortable to sit on and looks great, making it a perfect fit for your office, study, or home.
