Sihoo Doro C300 Pro

With its futuristic unibody design, the Sihoo Doro C300 Pro is more than just an office chair; it's an ergonomic command center. While retaining the iconic shape of the original, it revolutionizes the way we sit with its new "Cloud Mesh" fabric, which is even softer and more elastic, conforming to the body.

But where the C300 Pro truly shines is in its flexibility. In a world where we no longer just type, but also swipe and play, the 6D armrests are a game-changer. Not only can they be adjusted in every direction, but they also feature a unique "Upside Mode." When you lean back to read or play on your phone, you can angle the armrests upwards to perfectly support your arms—a feature often lacking in other chairs.

Speaking of comfort: The controls have been completely redesigned. With the Single Handle Control , searching for the right lever is a thing of the past. A single, elegant handle controls height, seat depth, and tilt. Combined with the new seat depth adjustment, the C300 Pro adapts perfectly even to taller users.

There are some exclusive features that are particularly interesting for power users and gamers:

• 6D armrests with upside mode: Perfect support for mobile gaming or reading while lying down.
• Cloud Mesh Technology: A sitting sensation like sitting on clouds, pressure-relieving and breathable.
• Integrated seat depth adjustment: Ideal for users with longer legs for better blood circulation.
• Single Handle Control: Intuitive control of all functions with just one handle.

Who: Tech enthusiasts, gamers, mobile workers, users over 1.85m tall.

When: Long workdays, mobile gaming sessions, relaxation phases with the tablet.

Why: 6D armrests for mobile phone use, luxurious Cloud Mesh, intuitive one-lever operation, adjustable seat depth.
