DORO C300 PRO V2

The First Full-Body Adaptive Ergonomic Chair

DynoCore Full-Body Support

Full-Body Support That Moves with You

Enjoy real-time, full-body support with the DynaCore system that tracks your movement and synchronizes the headrest, backrest, lumbar support and armrests to keep you comfortable as you shift, twist, or recline.

Forget About Readjusting

Stay supported and comfortable in every moment, as support moves with you.

For Every Part of You

Every part of the chair moves in harmony, delivering seamless full-body adaptive support.

Comfort Keeps Up With You

Continuous full-body support keeps you focused, comfortable, and effortlessly in flow—all day long.
 
SyncroFlex Backrest

Personalized Comfort. Instantly

Sit down and SyncroFlex Backrest immediately molds to your spine for instant, personalized support. As you recline it adjusts the recline path to match your movement—making the chair feel tailor-made for you.

Tailored Fit from the First Sit

Automatically contours to your spine for personalized support.

Personalized Tracking, Just for You

The backrest adapts to your body shape, delivering tailored comfort with every movement.
 
Self-Adaptive Dynamic Lumbar Support 2.0

Cradle Your Lower Back, Perfectly Your Way

Self-Adaptive Dynamic Lumbar Support 2.0 now features a wider support area that fully hugs the lower back, a pressure-relief spring that better adapts to horizontal movement, and three fine-tuning positions that range from a natural S-curve fit to full sacrum support.

Seamless Sacrum Support, Even in Recline

With 3-level fine-tuning and responsive springs, it dynamically tracks your body when leaning back, keeping your sacrum continuously supported and weightless.

Adaptive Fit for Every Body Type

The expanded surface dynamically molds to your unique physique and horizontal movement, delivering tailored lower-back support without complex adjustments.

8D Bionic Armrests

Arm Support Beyond Imagination

The armrests adjust in 8 directions — up and down, forward and back, 360° rotation, and tilt, to name just a few. Whether you are working in a relaxed recline or enjoying your favorite handheld game, your arms stay supported throughout.

Your Ally in Battle

The rear section of the armrest tilts up, providing comfortable elbow support for handheld gaming.

Nothing in Your Way

Flip the armrests sideways or backward to slide closer to your desk for deep focus.

Stay Aligned and Relaxed

The armrests tilt down to keep your forearms perfectly aligned with your desk, even while working in a relaxed recline.
 
Ultra-Wide 3D Headrest

Expansive Comfort. Precision Alignment.

The headrest now offers a 28% larger support area that envelops your neck and adjusts in three directions, allowing you to comfortably rest your head—precisely, even to the side—during work or breaks.

Height Fit for Any Torso

Adjusts smoothly up and down to match your neck’s natural height, ensuring personalized spine alignment whether tall or petite.

Cervical Curve Pressure Relief

Tilts up and down to directly support your cervical curve, relieving neck tension when switching between work and deep recline.

Inward/Outward Proximity Fit

Pivots back and forth to fill head-neck gaps, eliminating neck strain in both focused work and rest.
 
105°, 120°, 135° Recline

Your Recline, Your Way

Effortlessly find—and switch to—the perfect recline for every moment, from focused work to deep relaxation, while staying fully supported and comfortable throughout.

105°

Stay focused and work at peak productivity.

120°

Let your creativity flow—or unwind with your favorite game.

Sink into deep, full-body relaxation.
