Admin October 08, 2026
Among gem office chairs, the crystal office chair made by Japan's Factory - M and the flagship ruby office chair from Stressless are particularly notable, each with its own unique features.

Factory - M Crystal Office Chair from Japan
- Material and Weight: This chair uses amethyst as its stone material. The crystal weighs 88 kilograms, and including the metal parts of the chair, it weighs about 99 kilograms. Its metal frame is firmly inlaid, and the company claims that even a sumo wrestler can sit on it without any issues.
- Reason for Production: The company specializes in gem-related businesses. While searching for natural stones in the United States, they accidentally discovered a huge piece of amethyst. After bringing it back, they added wheels and a support frame to create an office chair.
- Price and Market Reaction: Currently, the chair is priced at 450,000 yen, equivalent to over 20,000 RMB. Dozens of buyers have expressed interest, but it has also been heavily criticized by netizens. Many people are afraid to sit on it, fearing that their buttocks might get stuck in the chair. Some have even suggested adjusting the crystal protrusions according to human acupuncture points to make it a massage chair.
Stressless Flagship Ruby Office Chair
- Material: It uses high-quality Batyck leather, which is soft to the touch, wear-resistant, and easy to clean, meeting daily use requirements and reducing the hassle of cleaning and maintenance.
- Ergonomic Design: The curves of the backrest and seat cushion fit well, effectively relieving fatigue caused by prolonged sitting. The fixed armrest design reduces arm muscle tension, and the adjustable headrest provides additional support for the neck, making the user more comfortable during office work.
- Functional Features: It is equipped with a pneumatic height adjustment system, which is easy to operate. Users can easily adjust the chair height according to their own needs. Its classic black appearance fits well with various office styles and is suitable for users with a limited budget who need basic comfort. However, it is not strictly gem-focused in a real sense; it just has the word 'ruby' in its name.
