How to Use Takumi Ergonomic Office Chair: Adjusting Seat Height and Depth
Seat Height Adjustment
Locate the height adjustment lever beneath the seat on the right-hand side. While seated, lift the lever and either apply slight upward pressure to raise the seat or allow your weight to lower it.
Adjust the seat so that your feet rest flat on the floor, with your thighs parallel to the ground and your knees at a 90-degree angle. This positions your body in an ergonomically ideal posture to reduce strain on your lower back and legs.
Seat Depth Adjustment
Find the seat slider lever under the seat, often located near the front or side to adjust the seat depth. Slide the seat forward or backward until there is approximately a two-inch gap between the back of your knees and the front edge of the seat.
This gap is crucial for maintaining proper blood circulation and avoiding pressure on the backs of your legs, which could lead to discomfort or tingling over time.
Why These Adjustments Matter
Proper seat height and depth adjustments are critical for promoting healthy circulation and reducing strain on your legs and lower back. By ensuring your body is adequately supported, these settings improve posture, increase comfort during prolonged sitting, and contribute to long-term ergonomic health.
Using the Lumbar Support
Adjusting the Lumbar Support
To adjust the lumbar support, locate the lumbar adjustment dial or slider, usually positioned on the backrest of your chair. This feature allows you to raise, lower, or increase the firmness of the lumbar support. Carefully adjust the support until it aligns with the natural curve of your lower back.
A proper alignment ensures that the lumbar area is well-supported, reducing the strain on your spine and improving overall comfort. Spend time fine-tuning this setting to match your preferences and body shape.

Benefits of Proper Lumbar Support
Proper lumbar support provides numerous benefits, particularly for individuals who sit for extended periods. It helps to reduce lower back pain by maintaining the spinal column’s natural curvature, preventing slouching and undue pressure.
Additionally, it promotes enhanced spinal alignment, which can improve posture and reduce the risk of developing chronic discomfort or musculoskeletal issues. By encouraging upright sitting, adequate lumbar support also ensures that you remain focused and comfortable during long sessions, making it an essential aspect of ergonomic seating.
Configuring the Armrests
Height Adjustment
Properly adjusting your armrests is crucial for maintaining a healthy ergonomic setup. Start by raising or lowering the armrests until your elbows form a 90-degree angle while typing or writing. This helps to maintain a neutral wrist position and prevents unnecessary strain on your forearms and shoulders.
Width and Angle Customization
To achieve optimal comfort, adjust the width of the armrests by moving them closer together or farther apart to complement your natural arm positioning. Additionally, many armrests allow for angle customization—tilt them inward or outward to provide tailored support for your arms and wrists. These adjustments can be particularly useful for accommodating different tasks or personal preferences.
Importance of Armrest Adjustment
Proper armrest configuration plays a vital role in reducing physical strain over long periods of sitting. Adjusted armrests support a relaxed posture by minimizing shoulder tension and wrist strain, allowing for greater focus and productivity.
They help distribute the weight of your arms evenly, reducing pressure on your neck and upper back. Investing time to fine-tune your armrests ensures maximum comfort and contributes to overall physical well-being during extended work or leisure sessions.

Reclining and Backrest Adjustments
Tilt Tension Control
The tilt tension control is a critical feature for customizing the reclining resistance of your chair. Located under the seat, the tilt tension knob allows you to fine-tune how much force is required to lean back. If you prefer more control and a firmer resistance, increase the tension.
Conversely, if you enjoy effortless reclining, decrease the tension for a smoother experience. Proper adjustment ensures that the recline matches your body weight and movement preferences, enhancing comfort and usability.
Reclining Angle Lock
Finding the ideal angle for your backrest is key to a functional and ergonomic setup. Use the angle lock mechanism to secure the backrest in your desired position. An upright posture with the backrest angled at 90–100 degrees is recommended for focused tasks to maintain concentration and proper alignment.
For more relaxed moments, slightly recline the backrest to 100–110 degrees, offering better support and minimizing fatigue. The lock feature ensures stability while preventing unintentional movements, contributing to both comfort and productivity.
Synchronizing Recline with Posture
Combining a slight recline with appropriate lumbar support promotes dynamic sitting, which is essential for spinal health. A synchronized recline allows your chair to accommodate subtle shifts in posture, reducing stiff and static positions during long periods of sitting. Maintaining this balance fosters flexibility and supports natural body movement.
Why Reclining Matters
Reclining is more than just a feature—it’s a preventative solution for long-term comfort and physical health. By slightly shifting your sitting angle, reclining helps alleviate pressure on the lower back while distributing weight more evenly.
It also promotes better blood flow, reducing the risk of stiffness and fatigue. Incorporating a well-adjusted recline into your routine encourages relaxation, enhances posture, and contributes to overall well-being.
Incorporating the Headrest
Adjusting the Headrest
Ensure your headrest is properly positioned to maximize comfort and support. Raise or lower the headrest so that it aligns with the base of your skull. This alignment ensures that your neck is supported without adding unnecessary pressure. Tilt the headrest to cradle your neck during use, particularly reclining, for enhanced stability and relaxation.
When to Use the Headrest
The headrest is especially helpful during moments of rest or low activity, such as taking a break or reading. These are ideal times to lean back and allow the headrest to alleviate neck strain caused by prolonged upright sitting.
Ergonomic Benefits
A well-positioned headrest offers essential support for the neck and upper spine, encouraging proper posture and reducing the risk of tension. By incorporating a headrest into your seating routine, you’ll experience improved alignment and greater comfort, even during extended periods of sitting.
Daily Maintenance and Care
Proper maintenance ensures the longevity and functionality of your chair. By following a few simple steps, you can keep your chair in optimal condition and enjoy its benefits for years to come.
Cleaning Tips
To remove dust and dirt, wipe the surfaces of the chair daily with a damp cloth. Use a mild cleaner specifically designed for the material for fabric or leather parts. Allow the chair to air dry completely before use to avoid damage or discoloration.
Checking for Wear and Tear
Inspect the chair regularly for any signs of wear, such as loose screws, worn wheels, or malfunctioning adjustments. Tighten screws as needed and replace damaged components promptly to prevent further issues.
Proper Usage Habits
Avoid sitting on the armrests or reclining excessively beyond its intended limits to maintain the chair’s durability. Use the chair according to its design to ensure consistent performance and prolonged use.
