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.
The concept of a swiveling chair with castors was illustrated by the Nuremberg patrician Martin Löffelholz von Kolberg in his 1505 technological illuminated manuscript, the so-called Codex Löffelholz, on folio 10r. [1] One of the earliest known innovators to have created the modern office chair was naturalist Charles Darwin, who put wheels on the chair in his study so he could get to his specimens more quickly.

With the advent of rail transport in the mid-19th century, businesses began to expand beyond the traditional model of a family business with little emphasis on administration. The additional administrative staff was required to keep up with orders, bookkeeping, and correspondence as businesses expanded their service areas. While office work was expanding, an awareness of office environments, technology, and equipment became part of the cultural focus on increasing productivity. This awareness gave rise to chairs designed specifically for these new administrative employees: office chairs. American inventor Thomas E. Warren (b. 1808), designed the Centripetal Spring Armchair in 1849 which was produced by the American Chair Company in Troy, New York. [3] It was first presented at the 1851 Great Exhibition in London. [4] It was only around 1850 when a group of engineers in the United States began to investigate how chairs could improve health and relaxation by stressing posture and movement. [5]
The office chair was strategically designed to increase the productivity of clerical employees by making it possible for them to remain sitting at their desks for long periods of time. A swiveling chair with casters allowed employees to remain sitting and yet reach a number of locations within their work area, eliminating the time and energy expended in standing. The wooden saddle seat was designed to fit and support the body of a sitting employee, and the slatted back and armrests provided additional support to increase the employee’s comfort. Like modern chairs, many of these models were somewhat adjustable to provide the maximum comfort and thus the maximum working time. Famous designers sometimes designed chairs intended for office employees.
There are multiple kinds of office chairs designed to suit different needs. The most basic is the task chair, which typically does not offer lumbar support or a headrest. These chairs generally cannot be sat in for more than a couple hours at a time without becoming uncomfortable, though they often offer more room to move than higher-end chairs.
Mid-back chairs offer fuller back support, and with the right ergonomic design, can be sat in for four hours at a time or longer. High-end chairs in this category, such as the Herman Miller Aeron and the Steelcase Leap are comfortable for long periods. Some mid-back chairs in particular offer customization options that can allow for a headrest to be added.
Executive or full-back chairs offer full back and head support. Many executive chairs are designed to be sat in for eight or more hours at a time. These are typically the most expensive office chairs and often feature genuine leather upholstery.
For appropriately seating above average tall and/or heavy office workers, extra spacious and sturdy constructed chairs are offered. Office chairs designed for safely and comfortably supporting increased weights and sizes have to use durable (metal) structural components, making these chairs heavier than office chairs designed for average sized people.

In the 1970s, ergonomics became an important design consideration. Today, office chairs often have adjustable seats, armrests, backs, lumbar support, heights, and footrests, to prevent repetitive stress injury and back pain associated with sitting for long periods.
An “ergonomic” office chair can be “personalized” through numerous adjustment options:
Furniture refers to objects intended to support various human activities such as seating, eating (tables), storing items, working, and sleeping. Furniture is also used to hold objects at a convenient height for work, or to store things. Furniture can be a product of design and can be considered a form of decorative art. In addition to furniture's functional role, it can serve a symbolic or religious purpose. It can be made from a vast multitude of materials, including metal, plastic, and wood. Furniture can be made using a variety of woodworking joints which often reflects the local culture.
The Aeron chair is an office chair manufactured and sold by American furniture company Herman Miller. Introduced in 1994, it was designed by Don Chadwick and Bill Stumpf and has received numerous accolades for its industrial design. It is featured in the Museum of Modern Art's permanent collection. It has been cited as the best-selling individual office chair in the United States with over 8 million sold.
Sitting is a basic action and resting position in which the body weight is supported primarily by the bony ischial tuberosities with the buttocks in contact with the ground or a horizontal surface such as a chair seat, instead of by the lower limbs as in standing, squatting or kneeling. When sitting, the torso is more or less upright, although sometimes it can lean against other objects for a more relaxed posture.
A chair is a type of seat, typically designed for one person and consisting of one or more legs, a flat or slightly angled seat and a back-rest. It may be made of wood, metal, or synthetic materials, and may be padded or upholstered in various colors and fabrics.
A standing desk or stand-up desk is a desk conceived for writing, reading or drawing while standing up or while sitting on a high stool.
A car seat is a seat used in automobiles. Most car seats are made from inexpensive but durable material in order to withstand prolonged use. The most common material is polyester.
SteelcaseInc. is an international manufacturer of furniture, casegoods, seating, and storage and partitioning systems for offices, hospitals, classrooms, and residential interiors. It is headquartered in Grand Rapids, Michigan, United States.
A recliner is an armchair or sofa that reclines when the occupant lowers the chair's back and raises its front. It has a backrest that can be tilted back, and often a footrest that may be extended by means of a lever on the side of the chair, or may extend automatically when the back is reclined.
A swivel, swivelling, spinny, or revolving chair is a chair with a single central leg that allows the seat to rotate 360 degrees to the left or right. A concept of a rotating chair with swivel castors was illustrated by the Nuremberg noble Martin Löffelholz von Kolberg in his 1505 technological illuminated manuscript, the so-called Codex Löffelholz, on folio 10r. It is purported that Thomas Jefferson drafted the United States Declaration of Independence in 1776 while sitting on a swivel chair of his own design.
Active sitting is the practice of enabling or encouraging movement while seated. It is also commonly known as dynamic sitting. The underlying notion highlights the advantages of incorporating flexibility and movement while sitting, as it can positively impact the human body and allow the completion of certain tasks that require sitting. "Active sitting, consisting of modified chairs or stability balls, allows the body to stay dynamic while seated." One of the earliest forms of active sitting is the common rocking chair which allows forward and backward swaying motion.
A transfer bench is a bath safety mobility device on which the user sits to get into a bathtub. The user usually sits on the bench, which straddles the side of the tub, and gradually slides from the outside to the inside of the tub. Tub transfer benches are used by people who have trouble getting over the tub wall or into the shower, either because of illness or disability.
A wheelchair is a mobilized form of chair using 2 or more wheels, a footrest, and an armrest usually cushioned. It is used when walking is difficult or impossible to do due to illnesses, injury, disabilities, or age-related health conditions. Wheelchairs provide mobility, postural support, and freedom to those who cannot walk or have difficulty walking, enabling them to move around, participate in everyday activities, and live life on their own terms.

Computer-aided ergonomics is an engineering discipline using computers to solve complex ergonomic problems involving interaction between the human body and its environment. The human body holds a great complexity thus it can be beneficial to use computers to solve problems involving the human body and the environment that surrounds it.
A saddle chair uses the same principles in its design as an equestrian saddle. It is equipped with a chair base on casters and a gas cylinder for adjusting the correct sitting height. The casters enable moving around and reaching out for objects while sitting. Some saddle chairs have backrests, but most do not.
The Centripetal Spring Chair or Armchair was a 19th-century American office chair, and one of the first modern designs for office chairs.
A gaming chair is a type of chair marketed towards gamers. They differ from most office chairs in having high backrest designed to support the upper back and shoulders. Like many office chairs, they are customizable: the armrests, back, lumbar support and headrest can all be adjusted for comfort and efficiency. However, there are criticisms of gaming chairs. For example, they tend to be designed and marketed primarily for aesthetics at the expense of having worse ergonomics than modern office chairs.
Rowac was a hardware factory founded by Carl Robert Wagner in 1888 in Chemnitz, Germany which most notably produced furniture for industrial use. Carl Robert Wagner is regarded as the inventor of the steel stool, which among other things was chosen for the workshops and classrooms of the Bauhaus Dessau. Today, mainly stools, chairs and cabinets carrying the Rowac name are traded as antiques.
The right to sit refers to laws or policies granting workers the right to be granted suitable seating at the workplace. Jurisdictions that have enshrined "right to sit" laws or policies include Austria, Japan, Germany, Mexico, France, Spain, Argentina, the United Kingdom, Jamaica, South Africa, Eswatini, Cameroon, Tanzania, Uganda, Lesotho, Malaysia, Brazil, Israel, Ireland, Zambia, Guyana, the Indian states of Tamil Nadu and Kerala, and the British overseas territories of Gibraltar and Montserrat. Almost all states of the United States and Australia, as well as the majority of Canadian provinces, passed right to sit legislation for women workers between 1881 and 1917. US states with current right to sit legislation include California, Florida, Massachusetts, Montana, New Jersey, New York, Oregon, Pennsylvania, West Virginia, and Wisconsin.
