Ergonomic Chairs

Ergonomic chairs are ergonomic tools that have been specially designed, bearing in mind the demands of different jobs, in order for the worker to sit with comfort and efficiently carry out the task at hand. Ergonomic chairs are very important as far as safe computer workstations are concerned~ they are an integral ergonomic tool of a good workstation. Ergonomic chairs are specially designed to offer support for the back, buttocks, legs and arms, while reducing exposure to awkward contact stress, postures and forceful exertions. In order to create room for efficiency, ergonomic chairs have been made in a way to favour adjustability, including not just a knob for lowering and raising the chair but also some adjustability in the armrests of the chair and tilt of the back. Ideal ergonomic chairs are also made to have a sturdy frame, a great amount of support in the lumbar region and have adequate padding support to ensure you do not lose shape! In other to enable you have a good grasp of the features you should look out for in ergonomic chairs, their major components are discussed below.

Ergonomic chairs are usually fitted with good casters and bases in order to ease your movements and reduce any tipping possible. Usually, nylon casters make up the surfaces but at times, soft wheel casters are used for hard surfaces like linoleum, for example. Rubber locking casters can also be added to prevent tipping.

Seat pan is a very important component of ergonomic chairs in order to support the bulk of the user's weight. It is often great to buy an ergonomic chair that has dense small-cell foam padding or spring coils so as to retain its support and cushioning effect. The front part of the seat usually slopes down like in waterfall design. A fist gas is also created between the back of the knees and the front part of the seat pan in order to minimize the pressure on the back of the thighs. Tilt adjustments are also incorporated in the design of ergonomic chairs so as to facilitate the attainment of a good working or reclined posture. Some ergonomic chairs come with sliding mechanisms which allow users of deferent heights to adjust the distance from the back rest.

In the design of the backrest, the lumbar support is usually given much attention. The backrest is so perfectly designed to be able to clear the pelvis and ribcage and curved so as to provide adequate support. The lumbar support may be a built-in type that will allow for adjustment by just turning a knob on the side of the chair. A full lumbar support is particularly necessary; otherwise an inadequate lumbar support will place too much pressure on the spine. For the backrests of ergonomic chairs to have proper angle in out and height adjustments ensure the spine is properly aligned when one sits down. With the angle adjustment in place, a user is able to adjust to the angle of the backrest in relation to the seat pan. An armrest of about 2" is usually included so as to give needed surface area for relaxation.
