Key Features
Perfect fit for every size
The larger seat cushion, 6D coordinated armrests, seat-depth adjustment and extensive height adjustability across multiple components make the Doro C300 Pro more adaptable to a wide range of body sizes. Whether you’re between 152 cm and 190 cm tall, you’ll sit comfortably even during long hours in the Doro C300 Pro.
Adjustable Seat Depth for Custom Comfort
The DORO C300 Pro features an expanded seat cushion that creates a more generous seating area, ideal for users of all body types. Its one-touch depth-adjustment lever lets you slide the seat forward or back—ensuring your thighs are fully supported and your posture is precisely aligned for hours of fatigue-free comfort.
Adaptive Anti-Spine Lumbar Support
Thanks to the BM (Body Movement) Tracking System, the integrated lumbar support automatically conforms to your spine’s natural curvature—delivering continuous, posture-perfect comfort across every seating position without any manual adjustments.
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.
Arm support, now in 6D
The armrests deliver true 6D adjustability, moving vertically by 6.8 cm, sliding front to back by 4.8 cm and side to side by 8 cm, rotating 70° inwards and outwards, and flipping up 35°. This comprehensive range of motion lets you position your arms exactly where you need them—whether you’re working, studying or gaming for hours on end—and they co-ordinate seamlessly with the backrest to maintain proper support even when you recline for a break.
Control Doro C300 Pro with one handle
Adjusting the Doro C300 Pro is now truly effortless. An ergonomically placed lever on the right-hand side lets you fine-tune seat height, depth and recline angle with one smooth motion—no bending down or awkward reaching required. Simply grip the handle and tailor your seating position mid-session to maintain perfect posture all day.
Cradle your neck with pinpoint precision
The Doro C300 Pro’s headrest boasts multi-directional precision: easily raise or lower it, slide it forward or back, and rotate it to mirror the natural curve of your neck. Its generously sized cushion ensures plenty of surface area for side-resting, so whether you’re deep in focus or taking a momentary pause, you’ll enjoy tailored support and lasting comfort.
Soft as Clouds
Sink into cloud-like comfort with the Doro C300 Pro’s full-coverage breathable mesh. Engineered for superior elasticity and gentle against the skin, it delivers an airy, refreshing feel throughout the day. Plus, the tough, stain-resistant weave resists sagging and is hassle-free to clean—keeping your chair looking and feeling fresh session after session.
Adaptable & Inclusive Comfort
No matter your height or build, the Doro C300 Pro’s intelligent weight-sensing mechanism and precision linkage automatically calibrate recline tension to suit you—delivering a silky-smooth, perfectly balanced lean every time.
Designed to elevate your workspace
