"Relax and let inspiration flow—sit well and think better."
My sitting experience has been nothing short of comfortable. I’ve used the Doro S300 to work at my desk and reclined backward to watch movies on my projector, and I like its form when reclined backward.
Work Mode:
Lower the headrest for extra back support and let the adjustable lumbar pads hit just the right spot. Whether you’re tackling emails or powering through a project, the chair keeps your back aligned and comfortable all day long.
Relax Mode:
Kick back, raise the headrest, and recline for that almost weightless feel. The lumbar support stays in place, cradling your back while you relax for movie nights or long gaming sessions.
With a futuristic sci-fi blend of mesh fabric panels and a beefy aluminum spine, and enough visible springs to send any Slinky recoil in horror... These choices add to a luxurious utilitarianism that draws your eyes to each of its meticulous details, which both blends into your workspace and becomes a conversation piece if a friend or colleague ever enters said space.

Key Features
High-Tech Anti-Gravity mechanism
Dual dynamic lumbar support
Cloud-like Italian velvet mesh
Premium adjustable backrest
The spring seat support significantly improves over column-based or no suspensions. Like a car, this chair has suspension, cushions my drop as I sit down, and adjusts, helping support my weight even if I sit unevenly. Most chairs I have tested have no suspension like this or a simple column-based solution that is far from as good.
A weightless recline experience
Doro S300’s mechanism, with aerospace-grade elastic plates, lets you adjust the tension to suit your body. Lean back smoothly to any angle without locking, and easily return to an upright position when you're ready.
Lumbar support that cradles your back
The wing-like dual lumbar pads adjust to your body and posture, giving you solid lower back support. You can also fine-tune the angle (90°-105°) with the gas lift for a perfect fit.
Everything about the S300 screams quality and Doro S300 is a tinkerer's delight. Every surface can be repositioned so you can find the most comfortable sitting position possible.
