Office Chair
An office chair, or desk chair, is a type of chair that is designed for use at a desk in an office. It is usually a swivel chair, with a set of wheels for mobility and adjustable height. Modern office chairs typically use a single, distinctive load bearing leg (often called a gas lift), which is positioned underneath the chair seat. Near the floor this leg spreads out into several smaller feet, which are often wheeled and called casters. Office chairs were developed around the mid-19th century as more workers spent their shifts sitting at a desk, leading to the adoption of several features not found on other chairs. Many office activities such as writing or typing involve a forward seat position in front of a work station, emphasizing free use of the arms and hands for reaching and for dexterous activities. Other tasks, such as talking on the telephone, permit a recumbent posture. Static posture, sitting in a single position for long periods of time, places strain on the body an ...

Ergonomic
Human factors and ergonomics (commonly referred to as human factors) is the application of psychological and physiological principles to the engineering and design of products, processes, and systems. Four primary goals of human factors learning are to reduce human error, increase productivity, and enhance safety, system availability, and comfort with a specific focus on the interaction between the human and the engineered system. The field is a combination of numerous disciplines, such as psychology, sociology, engineering, biomechanics, industrial design, physiology, anthropometry, interaction design, visual design, user experience, and user interface design. Human factors research employs methods and approaches from these and other knowledge disciplines to study human behavior and generate data relevant to the four primary goals above. In studying and sharing learning on the design of equipment, devices, and processes that fit the human body and its cognitive abilities, the ...

Lift Chair
Lift chairs, or riser armchairs, are chairs that feature a powered lifting mechanism that pushes the entire chair up from its base and so assists the user to a standing position. In the United States, lift chairs qualify as Durable Medical Equipment under Medicare Part B. In a February 1989 report released by the Inspector General of the US Department of Health and Human Services, it was found that: lift chairs might not possibly meet Medicare's requirements for Durable Medical Equipment (DME) and lift chair claims need to be re-regulated. The report was stimulated by an increase in lift chair claims between 1984 and 1985 from 200,000 to 700,000. A ''New York Times'' article stated that aggressive TV ads were pushing consumers to inquire about lift chairs and, once consumers called in, a form was sent to them for their physicians to sign. Some companies would ship lift chairs before receiving a physician's signature; therefore, forcing the physicians to sign or else their patient ...
