Top 9+ Premium Ergonomic Chairs from Japan

Ergonomic chairs are designed based on scientific principles of the human body to provide the best posture, maximum comfort, and health support for users, especially during long periods of sitting. Explore the 9+ premium ergonomic chair models from Japan that are highly favored by users in the following article.

1. Important Components of Ergonomic Chairs

In addition to basic components, ergonomic chairs feature modern, advanced design elements compared to conventional office chairs. Key highlights of ergonomic chair construction include:

1.1. Headrest

Ergonomic chairs often come with a fixed or adjustable headrest made from soft materials like foam or fabric. With height adjustment features, a 2D headrest is designed to match the body’s structure, allowing users to easily switch between work and relaxation positions.

Benefits of the headrest include:

• Supporting and reducing neck pain: The headrest supports the head and neck, reducing pressure on the vertebrae, which minimizes neck pain and muscle stiffness, especially during prolonged computer use.

• Maintaining focus: When the neck is supported and relaxed, sitting posture is straighter, enhancing blood circulation to the brain, and improving concentration and work efficiency.

• Increasing comfort: The headrest acts as a solid support, reducing headaches and eye strain from holding the neck in a fixed position for long periods, providing a relaxed and refreshed feeling for the user.

1.2. Backrest

The backrest of a swivel chair is the component that connects the lumbar support system with the headrest, allowing you to relax by reclining after stressful work hours. The tilt of the backrest is typically designed to be easily adjustable to meet personal preferences. For maximum comfort, you might consider ergonomic chairs with breathable mesh backrests or premium leather upholstery, adding a touch of elegance to your workspace.

The backrest offers the following benefits:

• Spinal Support and Reduced Stress: The backrest helps maintain the natural curve of the spine, minimizing pressure on the lower back and keeping you comfortable during extended periods of sitting without fatigue.

• Reduced Back and Shoulder Pain: With correct support design, the backrest helps relieve tension in the back and shoulders, preventing common health issues associated with prolonged sitting and poor posture.

1.3. Lumbar Support System

The lumbar support system is a separate component made of plastic, positioned at the lower back of the chair. It allows users to adjust it up or down to align with their lower back position. The design, which conforms to the body, ensures a relaxed and comfortable posture during work.

The lumbar support system provides:

• Reduced Pressure on the Lower Back: The support design helps alleviate pressure on the discs and joints in the lower back, reducing discomfort and issues like disc degeneration and herniated discs.

• Maintaining Natural Spine Curvature: It ensures the spine maintains its natural curve, evenly distributing pressure and protecting the vertebrae, keeping the spine aligned and comfortable.

1.4. Armrests

While most office chairs have fixed or no armrests, all ergonomic chairs, even the most basic models, feature adjustable armrests. Armrests are typically made from plastic or metal alloys, with padding in plastic, fabric, or leather. Most high-end ergonomic chairs come with 3D or 4D adjustable armrests, allowing for height adjustments, rotation, and forward-backward movement.

Armrests provide the following benefits:

• Supporting the Arms and Reducing Pressure on Neck, Shoulders, and Upper Back: Armrests distribute the weight of the arms, relieving pressure on the shoulder and wrist joints, and reducing numbness and discomfort.

• Maintaining Proper Sitting Posture: Armrests offer solid support for the arms, keeping the sitting posture straight and reducing slouching or spinal curvature issues.

• Supporting Tasks: Adjustable armrests can be tailored to work needs, aiding in mouse use, keyboard typing, or writing, and providing support when sitting down or standing up from the chair.

1.5. Seat Cushion

The seat cushion is usually made from high-density polyurethane foam. Specifically, Okamura chairs use multi-density cushions, consisting of three layers of urethane foam with varying firmness, scientifically stacked. The front cushion is softer, reducing pressure on the thighs and improving blood circulation. The rear cushion is firmer, providing solid support for the hips, keeping the back straight, and stabilizing posture. The seat cover fabric can be made from various materials like fabric, mesh, leather, or a combination, offering a soft and comfortable feel.

The seat cushion offers the following benefits:

• Providing Comfort and Softness: Ergonomic seat cushions typically use soft, highly elastic, and breathable materials, reducing pressure on contact areas like the buttocks and thighs, and enhancing user comfort.

• Supporting Body Weight: The seat cushion evenly distributes body weight, reducing pressure on the coccyx and surrounding areas, minimizing the risk of discomfort and numbness.

• Promoting Proper Sitting Posture: Ergonomic seat cushions often feature a slight contour that conforms to the body, helping you maintain an upright sitting posture, improving blood circulation, and boosting focus and work efficiency.

1.6. Smart Adjustment Mechanism

Many high-end ergonomic chairs are equipped with smart adjustment systems featuring levers and knobs made from premium materials such as plastic, rubber, or metal alloys. These components are conveniently located under the armrests and seat cushion, allowing users to easily and quickly adjust the chair.

Benefits of the smart adjustment mechanism include:

• Creating the most comfortable sitting posture: The smart adjustment system allows users to customize the chair to fit their body size and shape, creating an ideal sitting position.

• Flexible adjustment of postures: Users can easily adjust the chair's height, depth, and tilt to suit various activities, from working to resting and relaxing.

• Maximizing convenience: The smart system enables easy chair adjustments with minimal effort, saving time and energy. All adjustment controls are within easy reach, providing the utmost convenience.

The smart adjustment mechanism is usually located directly below the armrests and seat cushion of the chair
