Highlights at a Glance
3D wide headrest
28% More Surface. More Neck Support.
A wider curved design creates more contact around the head and neck for a more secure, more comfortable fit.
Soft Support That Stays With You.
Three-way adjustment and built-in cushioning help reduce pressure and keep support close through every shift.
Domino™ Sacral-Lumbar Support
Support Where It’s Usually Missing
Not just for the lumbar. It helps support extend down toward the sacrum, filling the space where comfort is often lost.
More Contact. Less Pressure.
A broader, more flexible surface helps support feel smoother, more even, and more natural in every position.
SyncroFlex™ Glide System
Fits Different Body Types More Naturally
SyncroFlex helps the backrest adjust as you sit, creating a closer fit for different body types. It feels more natural from the very first lean.
Keeps Support in Place as You Move
As you lean back or shift, the backrest moves with you. This helps keep support close to your back and waist, so comfort feels more consistent.
4-Zone Synchronized Tracking
Coordinated Support Across 4 Key Zones
From head and neck to back, waist, and arms, four support zones move together with your body.
Moves With You. Stays Aligned.
Support follows your body as you lean, shift, and recline — helping comfort stay where it should.
8D Bio-Adaptive Armrests
25% More Surface. More Support.
A larger armrest surface supports more of your forearm, helping reduce pressure on the shoulders and elbows.
Ready for Every Position.
Work. Play. Recline. The segmented design adapts more naturally, so comfort stays with you through it all.
What Tech Reviewers Say
"The Doro C300 Pro V2 was built with comfort in mind. Its DynaCore system gives you full-body dynamic support—not just in the back, but in the headrest, lumbar, and armrests too. And with SyncroFlex, the chair moves with you, so you’re not constantly readjusting your fit."
"Sitting is not a static position, you're constantly adjusting, moving, leaning, and shifting overall without you even realizing it. And so, the question here is not is this chair comfortable, but rather does it stay comfortable while you move. Full body adaptive support will help you."
