Ergonomic Chair

Executive ergonomic chairs are more perfect and expensive, so these ones may have more complex mechanisms of adjustment:

• smooth change of height and depth of the seat;
• armrests must be adjustable for height and angle of rotation;
• synchronizing device “1:3″, simultaneously changing the angle of inclination of the seat and backrest in an ergonomic proportions (each degree of the seat inclination is equal to 3 degrees back inclination);
• mechanism of “rocking chair” – a rocking of the chair with a coefficient of elasticity precisely adjusted to your weight;
• materials of better quality: built-in metal frame for a five-way bearings, polyurethane, aluminum, wood or leather upholstery for the armrests, improved skin dressing for the front and upper surfaces of the seat and backrest, leather for the bottom and rear surfaces.

Some words about the rocking chair.

Executive ergonomic chairs must have decentralization of swing: the axis of oscillation in the mechanism of “rocking chair” should be brought forward from the center of the chair (as longer as better), so during a rocking in the chair your legs (knees) will not climb up and swing process will look decent and solid.

When selecting an ergonomic chair you must sit down and try all the adjustments and functions. This is the main advice in selecting the chairs and stools. The correct choice of the ergonomic chair is the main factor in the maintaining high efficiency and health for many years.

Let’s  formulate a minimal set of requirements for cheap, but best ergonomic chairs:

• presence of plastic armrests and five-way support with easy spinning wheels;

• possibility of using of one hand and without getting up from the chair to change the height of the seat and reclining of back . All adjustments should be easy and pleasant so it is the only way you train yourself to adjust the chair for yours figure, and not vice versa;

• the mechanism of the height adjusting must include the shock-absorber, softening the sharp change in the load on the spine when you are lowering on the seat;

• ergonomic back shape (lumbar roll under bending). This can be achieved by the form of a chair frame, and thickening of upholstery;

• thick layer of high elasticity foam with peripheral bulges (to facilitate fixing the vertical position) and a soft rounded front edge of the seat (allowing to avoid the systematic compression of blood vessels in the legs);

• safe material upholstery on “working” surfaces of the seat and backrest (thick cloth, leather, special “breathing” type of furniture fabric), avoiding overheating and cooling in all weather and humidity. For the bottom and rear surfaces it is acceptable to use the plastic or leatherette.

There are already many chairs and armchairs, that considered the most comfortable, ergonomically designed, useful for the back health and posture. Embody chair is another one of this category (from the creators of the legendary Herman Miller Aeron chair). Its creators have gone for six years and one million dollars for the development of the Embody chair .

The Embody chair, according to the company claims, promises to increase productivity at work, could improve blood flow and normalize cardiac function. The seat of Embody chair has four layers and constructed in such a way that will move along you, if you turn, rose, etc. In the back of the  Embody chair are built-in 56 flexors to properly support the back.

The cost of this chair is about $1600, you can choose one from 13 possible colors.
