This chair is for the person who spends long hours at a desk, whether you're working from home, gaming, or managing a side hustle. It's built to support you through back-to-back meetings or late-night projects, not just sit there.
Most ergonomic chairs talk about home office support, but the Doro C300 Pro focuses on active comfort that moves with you. The adaptive lumbar support isn't a static pad—it shifts as you lean or recline, so your lower back stays cradled even when you stretch. You'll notice the ultra-soft 6D armrests pivot smoothly to match your typing posture, reducing shoulder strain during marathon sessions.
Practical details make it work: the seat depth adjustment lets taller users find their sweet spot, while the intelligent weight-sensing device balances reclining with a gentle push. The breathable mesh keeps you cool during intense focus, and the 135° tilt angle offers a quick break without leaving your desk. It's certified for safety, so you can trust it day in and day out.
