Japanese Long-Sitting Office Chairs

Among Japanese long-sitting office chairs, Okamura's ergonomic chairs are representative products, integrating Eastern body shape characteristics with precision engineering to achieve healthy support and comfortable experience through multiple core technologies.

I. Core Series and Functional Features

1. Abilis Series: Focuses on cost-effectiveness, featuring a "3D floating lumbar support" that automatically adapts to body shape. When reclining, the lumbar support moves forward by 2cm to fill the lumbar gap, reducing waist pressure by 62% during 4 hours of continuous work. Its "butterfly-shaped seat cushion" has a 15° upward edge design to prevent compression of thigh blood vessels, suitable for users with heights ranging from 155cm to 190cm.
2. Sagesse Series: Features a tool-free assembly design, equipped with a "gravity-sensing base" that automatically adjusts reclining resistance. The "shoulder-neck linkage system" simultaneously fine-tunes the headrest when the backrest tilts, maintaining the optimal viewing distance between the eyes and the monitor. During午休 (noon break), a 135° recline still maintains the natural cervical spine curve.
3. Sylphy Series: Suitable for both gaming and office scenarios, the backrest is embedded with over 2000 elastic support points, capturing subtle body movements in 0.3 seconds. The "4D armrests" support 8cm of left-right movement and 5cm of forward-backward sliding. The surface is made of soft rubber material that stays warm in winter, and the 15° inward rotation design promotes natural elbow lowering.
4. Contessa2 Series: Positioned as a high-end product, it adopts a Japanese-imported "carbon fiber frame", weighing only 15kg but with a load capacity of up to 150kg. The "smart weight distribution system" monitors sitting posture pressure in real-time and reminds adjustments through micro-vibrations. The "fully touch-controlled adjustment panel" is hidden inside the right armrest, supporting multi-dimensional adjustments such as seat depth, lumbar support height, and headrest angle.

II. Five Core Technology Supports

1. Dynamic Spine Support System: A patented technology that moves the support points with sitting posture to maintain the natural curvature of the lumbar spine. Clinical tests show an average reduction of 67% in waist pain after 6 months.
2. Gas Lift Safety Certification: Passed the international SGS Level 4 test, capable of withstanding 2000kg of impact force, far exceeding the industry standard of 800kg, eliminating the risk of cylinder explosion.
3. Microclimate Mesh Fabric: Made of special mesh fabric from Toray, Japan, with 3 times the breathability of ordinary mesh fabric, keeping you cool during long sits in summer, suitable for subtropical climates.
4. Silent Caster Design: TPE material casters protect the floor and achieve library-level silent effects, ensuring no disturbance during late-night use.
5. 10-Year Warranty Commitment: The warranty period for core components reaches an industry-rare 10 years, with an average service life of 15 years and a daily cost of less than 1 yuan.
