ITOKI CORPORATION (Head office: Chuo-ku, Tokyo; President and CEO: Koji Minato) will release "SHIGA," a modern work chair featuring a neat, minimalist design that brings tranquility to the space and ergonomics that are close to the human body, for corporate and individual use starting in December 2025.

As work styles have become more diverse and liberalized, and technological advances have dramatically changed social norms and people's values regarding workplaces, the value of the office is being reassessed precisely because we can now work from anywhere.

The inspiration that comes from designed spaces, functional furniture that allows people to spend long periods of time comfortably, and spaces that naturally connect people. Itoki observed these changes and felt the need for a chair that combines beauty and comfort, incorporating an ergonomic mechanism that allows comfortable sitting even for long periods of time within a minimalist form, which led to the development of this chair.

1) The gently separated back and seat create a light impression
The chair reduces the sense of bulkiness felt in conventional task chairs and creates a slight gap between the back and seat, creating a sense of openness that allows light and air to pass through. This creates a light and airy impression in the space without creating a feeling of oppression.

2) A continuous spine line
There are two types of backrests: "double" and "triple."
The dividing line on the backrest creates a sense of unity within the series, and when they are lined up together, the continuous horizontal line creates a spacious and orderly impression.

3) A form that exudes the tranquility of furniture
It stands out from the ergonomic forms common in conventional office chairs, incorporating ergonomic three-dimensional curves within a simple square silhouette. Its design "enhances the user's figure without asserting its presence" - it combines a noiseless form with high comfort that gently supports the body.

1) Ergonomic locking mechanism mounted in an extremely thin gearbox
The SHIGA's comfort is supported by the extremely thin radio box located under the seat. Radio boxes tend to become larger as they become more multifunctional, but we have narrowed it down to just the essentials, achieving both a minimalist design and ergonomic rocking mechanism.

The rocking mechanism uses "Ankle Move Synchro Rocking," which is used in most of ITOKI's task chairs. The back and seat tilt in unison, with the ankle as the fulcrum, and when leaning back, the entire seat slides backward and downward, flexibly supporting natural changes in posture. This allows for a stable and comfortable sitting position while following the movement of the body (up to 15 degrees).

Furthermore, we pursued a noiseless finish with no visible screws on the back of the radio box. This structure, which has been refined to the utmost with only the essential functions, creates the quiet appearance and flexibility of the SHIGA.

2) Operation lever with consideration for accessibility
The single operating lever under the seat allows for simple adjustments to the height and backrest position. The initial angle of the backrest can be fixed with the push button at the end of the lever, and on the height-adjustable leg type, the seat height can be adjusted by rotating the bladed lever (90mm range).

3) Armrests that blend in with the interior
The armrests are made of aluminum, giving them a refined appearance and a luxurious feel. The adjustable armrests can be adjusted to your preferred height by pressing the button on the front of the armrest (80mm range).

SHIGA's design fits a wide range of settings, from offices to living spaces.
In addition to seven types of body specifications, the chair is available with original fabrics that can be chosen from eight sophisticated solid colors or seven light two-tone colors. The lineup also offers a wide variety of variations, including fabrics from Kvadrat, a leading Nordic textile brand, in three colors, and genuine leather with a high-quality feel in two colors.
The frame is available in seven finishes: satin paint (3 colors), aluminum mirror, and gloss paint (3 colors), resulting in approximately 500 possible combinations.

In the office, it blends naturally into the space where wooden fixtures and fabric materials are mixed, creating a consistent aesthetic across zones such as work areas, meeting areas, and lounges.

At home, on the other hand, it blends in with the interior of your living room or study, functioning as a chair to support your work hours without disrupting the home atmosphere.

The texture of the material and the high-quality, subdued coloring harmonize to create a comfortable chair that you will find "comfortable" even when sitting on it every day.

The name "SHIGA" comes from Omihachiman City, Shiga Prefecture, where our manufacturing base is located.
The ITOKI Shiga Factory, located in the same area, is an important place where high quality control utilizing technology and reliable craftsmanship that continues to pursue technological improvement are alive and well.
The design and production techniques we have cultivated over many years have enabled us to achieve both minimalist design and functionality, including the compact under-seat area that is a feature of "SHIGA." The support pillars connecting the back and seat are also light, while the chair is strong and safe enough to be used comfortably for long periods of time. We have also achieved a wide variety of variations thanks to our production experience and challenges.
"SHIGA" is a product that brings together all of ITOKI's manufacturing expertise.
