One of the most common pieces and kinds of furniture used in practically all buildings worldwide, a chair refers to a type and variety of seats for usage by a single person. Its primary features comprise two pieces or sections of sturdy and durable material fastened to a padded vertical back and a horizontal seat at an angle of ninety degrees or higher. The four corners of the level saddle are in turn joined to four rod-like structures or legs.
[read more] The legs are generally long and high to allow the thighs and knees of the seated person to form a ninety-degree angle or lesser. All the components and parts of a chair are strong enough to withstand a broad range of weights of individuals who sit on the horizontal seat and lean against the vertical back but to a certain extent.
What Materials Get Used to Make a Chair?
Chairs composed of a variety of materials are available in the market. They range from plastic, metal, and synthetic constituents to wood and sturdier resources like acrylic or stone. Two or more than two of these can get mixed and used together to create a chair. For example, the framework and legs may be metal, while the saddle and back may encompass plastic.
The most common types are the ones made of wood. The commercial varieties that get sold and purchased in bulk are of plastic. The metal and other types are comparatively durable and expensive. Nevertheless, each kind has its unique use and purpose.
The chairs may possess an overall hard and stiff surface or may come covered with paddings and upholsteries. They may have designs or percolative materials or holes and gaps for decoration and ventilation.
Ornaments on chairs may encompass creative materials like recycled cutleries, play bricks, folded cardboard, and ropes. These can also include plumping tubes, PVC pipes, and so on for an ornamental and embellished look.
The Design and Ergonomics of a Chair
The design of a chair always considers its ergonomic factors like comfort, convenience, and intended usage. It also analyzes and respects the non-ergonomic elements such as stacking ability, durability, size, stain and rust resistance, weight, foldability, and artistic outlook. Let us see what each factor entails.
An effortlessly adjustable seat height makes it easy to distribute the load of the seated person to the other sections of their body. Gas springs connected to the body of the furniture serve this purpose, making it more comfortable for the user.
A saddle that lies at a higher elevation results in suspending feet. It leads to heightened stress on the base of the knees and sustaining pain on the toes. Conversely, in a lower seat, one can shift the weight and exert them over the hip bones. Some chairs may come with footrests or a straight or rounded bar near the base for the person sitting on it to put their toes on and relax.
The measurements for a standard chair depend on the average dimensions of a person’s body or the involved anthropometric. The two most essential aspects of the latter include the popliteal height (distance from the base of the foot to the underside of the femur at the knees) and hip popliteal length (average elevation of the furniture seat).
The Angle of Reclination:
The purpose for which the chair gets used determines its reclining angle. The ones used at work and office tables must recline only slightly to prevent the occupant from being too distant from the desk. On the other hand, dental chairs must have a high reclining angle. The ones for television watching lies in between the two.
Research has discovered and stated that the ideal angle of reclination for the best seating posture is 100-110 degrees. It can be when the backrest tilts autonomously of the saddle or when the entire chair is slanted back. Overall, a reclining backrest decrease the load exerted on the back muscles of the seated person. Due to this reason, most chairs have at least a slight reclination. However, this inclination angle may not suit the ones intended for dinner tables.
Head and Back Support:
A chair’s backrest sustains a portion of the mass of the seated individual and curbs the strain on the different sections of their body. Generally, such supports are available in three heights. The lower backrest braces the vertebral column, and the shoulder elevation tolerates weight from the entire backbone and shoulders. The headrests hold up the head and prevent neck injuries in and during jerkings and collisions when the former gets yanked back abruptly and unexpectedly.
Reclining chairs come with backrests that are at least at the height of the average person’s shoulder to direct the burden to the shoulders and not the lower spine.
Back and Seat Padding:
Chairs like the ones for outdoor purposes do not require padding. Nevertheless, some people prefer the saddle and back padding due to the comfort they provide.
In most cases, contouring is the preferred choice. It endeavors to divide the weight without the use and application of padding. The bulk gets allocated equally, and the maximum pressure gets reduced by matching the shaping of the seated individual’s buttocks.
Chairs that come with armrests are called armchairs. They support a portion of the mass via the arms. When in the resting position, they are at elbow height. They sustain the overall length of the hand without putting any pressure on the sensitive area of the elbow region. The armrests can move between the side and the front of the furniture, allowing for an effortless entry and departure.
Size of Seat and Space for Leg:
Besides popliteal height and hip popliteal length, added anthropometric estimations are essential in outlining a chair. The hip breadth can determine the chair and the width of the armrest, while the buttock to knee length can establish the legroom required between any two subsequent rows or series of chairs.
Varieties of Chairs
In this world, a colossal number of kinds and types of chairs exist. They may differ based on their formal usage in the domestic and corporate sectors.
Overall, chairs can get categorized into the following sorts:
Office Chair: Used by corporate employees, office chairs proffer an elegant and professional look and design. They come with features of adjustability and mobility due to height calibration functions towards the base of the saddle and caster wheels connected to the feet, respectively.
Dining Hall Chair: As the name suggests, dining hall chairs get used in standard residential homes at the dining table. They may also appear in conventional settings like corporate and wedding banquets that involve a ceremonious meal.
Work Chair: Work chairs are specialized and adapted for use and application by working professionals or in a similar environment. Each such piece of furniture is different and diverse for various jobs. To understand it better, let us consider the case of a designing chair and an auditorium one. The former will have a high easel and added height and differ from the latter in various aspects.
Rocking Chair: Rocking chairs come with two arched groups of wood connected to the base of the stems of the furniture, proffering the elements of coziness and relaxation.
Kneeling Chair: Kneeling chairs allow the knees to carry the pressure and mass of the seated person and distribute a significant portion of the bulk of their feet. They are padded and come with cushions. The padding can get applied solely to the chair seat or both the seat and backbone. They can also be on the arm and footrests. It helps disperse the burden by increasing the contact area between the body and the furniture and reducing the exerted pressure. The majority of the bodyweight gets sustained in the back section of the saddle. Thus, the padding must be firmer there compared to the frontal area receiving and supporting the mass of the feet.
Wing Chair: Also called a wing-back chair or club chair, a wing chair comes with “wings” joined to its back, generally stretching down to the armrest. The “wings” protect the seated individual from drafts and traps the heat received from fireplaces or heaters. They come upholstered with exposed wood and padded cushions at the back, seat, and armrest.
Folding Chair: The most commonly used chair in recent times, a folding chair, is a type of furniture that bends at particular joints to collapse to a smaller size. Primarily employed during outdoor activities, they are light, portable, and storable.
A few unique varieties and types of chairs with additional accessories exist besides the traditional designs and styles. These components or parts may be connected to the front, back, top, or base of the furniture, differing in their construction and purposes.
Some chairs may come with a short stool called an ottoman instead of the general and typical integrated footrest. This ottoman works both ways by serving as a resting area for the foot and a low bench. When matched with glider chairs, individuals can mount it to swing arms to rock it to and fro with the principal and focal glider.
Side chairs may come with a temporary cloth cover called a chair cover. They primarily get used during formal events where there are numerous guests to impress and serve. Chair covers hide the underlying stains, cracks, blemishes, and other flaws, proffering an attractive and elegant look to the furniture. They may come in a single color or a mixture of several hues with stunning patterns and a ribbon tied like a bow behind the object it is covering. They also serve their purpose with sofas, tables, and couches.
Chair pads refer to cotton or foam padded cushions that one can externally add to a chair. They get used by individuals for relief from back pain or merely for ornamental and decorative reasons. When used in cars, these paddings can extend the height of the saddle of the driver. Chair pads can also work with kitchen chairs or for young children.
Remote control bags are a great discovery within the list of chair accessories. Individuals can drape them above the arm of chairs and sofas to hold the remote controls for home theaters. To prevent them from slipping off the side due to the electronic controller’s weight and falling off, they are counter-weighted.
Chair gliders are fittings fastened to the legs of the furniture to deter them from sliding, snagging, or scratching the floor beneath.
