Fewer parts, less material, and still everything a good chair should be

Operation location: Sitting down, front lever of two levers on the lower left of the seat
Lean forward : Lean against the backrest and put your weight on it to recline it slightly. Then pull down the lever and stop leaning against the backrest. When you stop leaning, it will lean forward.
Return to normal position : Lean back against the backrest, put your weight on it, and recline it slightly. Then, raise the lever and stop leaning against the backrest. When you stop leaning, the forward tilt function is released.
Operation location: Lever under the left side of the seat
While sitting on the seat you want to extend , pull the lever diagonally upwards to the left and slide your thighs forward.
With your hips raised , pull the lever diagonally upwards to the left and use your right hand to slide the seat back.
*Adjust the depth so that the backs of your knees are not pressed against the front edge of the seat.
Round knob on the bottom right of the seat
While seated, turn the stiffening knob forward.
While seated, turn the softening knob backwards. *The backrest is at the right firmness when it tilts backwards while supporting your back when you lean lightly against it and naturally moves up as you return to an upright position.
The lever behind the two levers on the lower left of the seat
Setting the range Without leaning against the backrest, push the lever forward. Select the position you want to set the range.
To cancel the setting , move the lever backwards (as far back as it will stop) without leaning against the backrest.
Raise the arm little by little while raising the lever on the outside of the arm . Release the arm when it reaches the desired height.
Lower the arm slowly while raising the lowering lever. Release the arm when it reaches the desired height.
* Place your forearms on the arm pads and adjust the height so that your shoulders do not rise.
Flat lever on the bottom right of the seat
Sit on the seat you want to raise and raise the lever while slowly lifting your hips. Release the lever when it reaches the desired height.
While sitting on the seat you want to lower , raise the lever and release it when it reaches the desired height.

Yves Béhar <br>Herman Miller asked designer Yves Béhar to develop an affordable chair that combined all the hallmarks of Herman Miller: beautiful design, cutting-edge ergonomics, sophisticated engineering, and environmental friendliness.
Béhar began by exploring how to create a design that "produces the most with the least amount of materials." He then looked at the Golden Gate Bridge, the most famous landmark in San Francisco, where he lives. He wondered if the engineering principles of a suspension bridge could be applied to a chair.
So why is this chair called "Sail" and not, say, "Bridge"? Look at the chair from the side. Doesn't it look like a sail on a sailing ship? The name "Sail" evokes the sailing ships passing under the bridges that inspired these unique designs. We also chose to use a "y" instead of an "i" in "sail" to refer to the "Y" in the chair's innovative Y-tower structure. The concept of using suspension towers to support a frameless suspension back allowed the elastomer material to be tensioned to provide maximum tension where support was needed, and strength where it was not restrictive to free movement.
Design is about solving fundamental human problems
Founded in 1923 (its predecessor, Star Furniture Company, was founded in 1905), Herman Miller bet its survival on contemporary furniture during the Great Depression of the 1930s. This gamble was a huge success, and in 1945 Herman Miller stopped producing traditional furniture and focused its business on contemporary furniture, which would later be called modern furniture. In 1960, the company began exploring the true needs of office workers and the needs of companies and organizations. They realized that office productivity was a major issue in business. The "Action Office" that was developed in this way became the standard for subsequent office systems.
Herman Miller considers innovation to be the result of research, not a goal. Innovation comes from research into customer needs, exploration of materials and processes, and design in response to social and economic innovation. Of course, designers add inspiration on top of that. Charles and Ray Eames' plywood chairs, Robert Propst's Action Office, Bill Stumpf's Ergon and Aeron chairs, and Ayse Birsel's Resolve system are all born from such interactions. What connected them to Herman Miller is the shared belief that "design exists to solve fundamental human problems." It is the passion to create new designs from research into the human body structure and the environment surrounding humans, rather than designing for the sake of design.
The quality control department repeats the industry standard 100,000 seat tests 1 million times. The unparalleled research and development department develops from the material, and the manufacturing department realizes the most advanced manufacturing process. In all of these, Herman Miller never forgets its idea of creating new designs by researching the human body and the environment. Herman Miller's products are the inevitable form that was born from researching the problems related to the act of sitting. In order to save global resources and reduce the environmental burden, Herman Miller's products strive to improve the durability and reliability of its products, and the product warranty period for work chairs is 12 years. Another aspect of innovation, "taking risks," is equally important. Herman Miller strives to always maintain a willingness to take risks. As the company expands and the responsibility for capital increases, the pressure to minimize risk has also increased. However, Herman Miller continues to take risks to bring out new products that it is confident will be successful - and sometimes products with revolutionary qualities that will change the times.
