Lavenne R9 Dynamic Ergonomic Chair

From the IDEA Bronze Award to the MUSE Gold Award, New York Design Awards, and London Design Awards, Lavenne R9 has earned international  recognition for its innovative approach to ergonomics, comfort, and  modern workspace design.

Recognized with industry awards and featured by leading media such as  FOX and CBS, the R9 has been independently validated for its breakthrough  in dynamic ergonomic design. This is not just a chair we built—it’s a concept  tested, reviewed, and acknowledged by the industry.

NoodleNick, a tech and gaming creator with 1.11M YouTube subscribers, tested  the Lavenne R9 Pro in a real-world desk and gaming setup. What stood out most  wasn’t just comfort—it was how different the chair felt from a typical office  chair. From its retro-inspired design and extra-wide armrests to the hidden  powered support system, footrest, and extensive adjustability, the R9 Pro felt more  like a complete workspace upgrade than just another chair. For users who  constantly adjust their seating position throughout the day, the R9 Pro offers the  flexibility to work, game, recline, and move comfortably in one chair. Click the  video below to watch the full review.

Dr. Matthew Posa, DC, a Neuro-Structural Corrective Family Chiropractor, reviewed the Lavenne R9 through a spine-care lens, highlighting its VTS Dynamic Spine, 5° Forward Tilt, recline modes, footrest, and 11-air-chamber system—because the body is built to move, and a chair for long-hour sitting should support that movement.

Follow Jamel, a 30-year-old government nurse and gamer from New Jersey.  Spending anywhere from 2 to 12 hours a day on study sessions and gaming  streams, he struggled with insufficient back support, restricted mobility, and  limited reclining flexibility. With the Lavenne R9 Pro, Jamel found a chair designed  to move with him, helping him stay supported and comfortable throughout his  longest sessions.

Follow Merv, a 47-year-old DevOps Engineer from the US, through his 8+ hour  workdays with chair. After struggling with poor long-hour support, limited recline  and footrest options, and static backrest design in his previous chair, Merv found  a more adaptive sitting experience with the R9 Pro’s electronic adjustments,  dynamic support, and massage function.

Step inside the R9 factory, from workshop floors and molded parts to assembly lines and packaging preparation, and see how R9 moves from design to real production.

Most ergonomic chairs only support a small section of your back. Change your  posture, and that support disappears. The Lavenne R9 Pro is built differently. Its  VTS Dynamic Spine, Ergo-Curve Backrest, and Powered Air System work  together to follow the natural curve and movement of your spine, delivering  continuous full-spine support at every movement.

The Powered Air System offers four dedicated support modes that can be switched instantly through the Smart Controller. By changing how the 11 air chambers inflate, the R9 Pro provides targeted support for different postures and working scenarios throughout the day.

Most chairs separate the headrest and backrest, creating a support gap that  leads to neck strain over time. The Lavenne R9 Series integrates both into a  unified S-curve structure, where headrest and backrest work as one system.  A manually adjustable air cushion lets you fine-tune support for proper neck  alignment while reclining or working at every position of use.

The Lavenne R9 Series features true 5D ergonomic armrests with full 360° rotation, adjustable in height, depth, width, and angle, allowing the armrests to adapt precisely to different body types and sitting postures for personalized comfort.

Most seat cushions use a flat, straight-edge design that concentrates pressure on the front of your thighs during long sitting sessions. The Lavenne R9 Series uses a waterfall seat edge that gently slopes downward, reducing pressure on the thigh muscles and improving comfort during extended use.

The R9 Series features infinite height adjustment, allowing continuous fine-tuning instead of fixed levels. This ensures the chair can precisely match different body proportions and maintain stable hip, knee, and spine alignment throughout long sitting sessions.

The headrest offers precise height adjustment to align with different body proportions and seating positions. It maintains consistent support between the head, neck, and upper spine, ensuring stable alignment during every position.

The lumbar system can be manually adjusted to match individual spinal curvature, delivering targeted support to the lower back. It helps distribute pressure more evenly across the spine and improves long-term sitting stability.

Traditional ergonomic chairs rely on fixed recline angles.But the perfect angle isn’t the same for everyone. Powered by a carbon-fiber flex chassis, the Lavenne R9 can hover smoothly at virtually any recline angle – balanced, effortless, and fully supported.

The more focused you are, the more likely you are to lean forward—and lose proper support. The Lavenne R9 Series features a 5° Adaptive Forward Tilt that moves the entire chair system forward, including both the chassis and backrest, rather than simply tilting the seat. This helps maintain natural spinal alignment, promotes a more focused working posture, and delivers meaningful support during typing, designing, coding, meetings, and other real-world work scenarios.

Each preset is designed around a different way of working and relaxing.

105° Forward Tilt for focused work and deep concentration.

110° Upright for everyday productivity and task management.

130° Recline for meetings, reading, and content review.

150° Relax for recovery and relaxation between work sessions.

With four quick-switch presets, the Lavenne R9 Series lets you instantly move between the most commonly used sitting positions—no manual fine-tuning required.

Long hours of sitting can gradually wear down your body, especially when you remain in the same position for extended periods. To help address this, the Lavenne R9 Pro uses 11 intelligent air chambers and 6 Smart Massage Modes to create dynamic movement across your body, helping you stay active, refreshed, and comfortable throughout the day.

Traditional chairs hold your body in static positions. R9 Pro redefines support through continuous adaptation — combining active air support, VTS dynamic spine tracking, and seamless recline to respond in real time to every shift in posture. Support is no longer something you “sit on” It moves with you — and never falls behind. | Where others stay fixed, R9 Pro keeps adapting.

At Lavenne, our journey began with a simple realization: ergonomic chairs shouldn’t be static. Real work is dynamic, and support should move with you—not disappear when you change positions.

To create a better solution, we brought together experts in ergonomics, biomechanics, and engineering to rethink how a chair supports the body. After more than three years of research, testing, and refinement, we developed the Lavenne R9 Series—a chair designed to support your every movement.

We envision a future where sitting becomes a source of comfort and well-being, not fatigue.

The Lavenne R9 Series combines high-elasticity mesh, 4D knitted fabric, a durable aluminum alloy base, silent caster wheels, and a carbon-fiber chassis to balance comfort, breathability, stability, and long-term durability. Every material is carefully selected to enhance the way the chair feels, moves, and performs throughout years of daily use.

Every critical component of the R9 has undergone rigorous durability, strength, stability, and fatigue testing to ensure years of reliable performance under real-world use.

Anyone can claim durability. We prefer to prove it. From stability and strength testing to repeated fatigue cycles, the Lavenne R9 Series has been engineered and verified to perform under the demands of everyday work and long-term use.

Every component and tool has been carefully packaged to ensure a smooth and hassle-free assembly experience. From unboxing to final setup, the Lavenne R9 Series is designed to get you comfortably seated in just a few simple steps—because a great sitting experience starts the moment you open the box.

Inside, you’ll find everything needed for assembly and setup, including chair components, tools, a Quick Installation Guide, a Warranty Card, and, for the R9 Pro, powered-system accessories, a Battery, and a Smart Control User Manual.

Please note: Package contents may vary slightly depending on the model selected. All models include a Quick Installation Guide and Warranty Card, while the R9 Pro includes additional powered-system accessories, a Battery, and a Smart Control User Manual.
