How to make a knee chair with your own hands

Having seen a knee chair for the first time, not all of us will understand what it is. An interesting design that doesn't quite look like a standard stool or chair might make you wonder how you can sit on it.

Orthopedic knee chair manufacturers claim that this is the best invention for keeping your back healthy and preventing scoliosis.

The design of the furniture on which a person sits directly affects his posture, the state of the musculoskeletal system and health.

Ordinary chairs have a back and we, leaning on it, can keep our posture, but as soon as we break away from it, our back gradually tilts, and we begin to slouch, looking for the most comfortable position. The knee chair solves this problem by relieving the bulk of the load on the spine. The greater the angle of the seat, the smoother your back will be. You simply cannot bend and stoop your back.

The knee chair is a product with orthopedic properties that significantly exceed the positive effects of other treatment chairs.

What is a knee chair? This is a structure made of wood or metal, created to relieve the main load from the spine when sitting, due to the support on the knees. Serves to form the correct posture.

Any orthopedic chair is designed to provide not only comfortable sitting, but also health benefits.

History of appearance

In 1970, the Danish scientist Mendel was engaged in the observation and study of the postures of people leading a sedentary lifestyle, office workers, schoolchildren. Considering how they sit, he concluded that the most comfortable position for sitting on a regular chair is to lean the body forward relative to the pelvis. It is this repetitive position of the body that leads to curvature of the spine and other back diseases.

For many decades, scientists have tried to find a design that would fully meet all the requirements.

Based on this, he designed a chair with the seat tilted 15 degrees downward. Such a structure helped to maintain correct posture, but it had its drawbacks. A person sitting on such a chair would constantly roll off of it.

The most useful is an armchair with a seat at 15 ° to the horizon.

A number of researchers from Norway became interested in Mendel's work and in the course of development, they improved the knee chair by inventing a knee support. Thus, they managed to evenly distribute the load on the buttocks and knees, and the spine began to serve as the center of gravity. The body of the seated person reflexively straightened at the slightest tilt forward.

The result was a chair with a half-bent footrest that you kneel on.

One of the developers of such a chair was the owner of a furniture factory, Peter Opsvik. It was thanks to him that such a chair hit the store shelves.

Therapeutic action

The knee orthopedic chair model allows you to adjust the height of the seat, adjusting to each one. With a properly adjusted chair, the load is distributed approximately 60 to 40. Of these, 40 percent of the load goes to the knees and only 60 to the pelvis.This allows you to significantly relax your back muscles and take a comfortable position without tilting the body forward. Those. you will be comfortable sitting on such a chair with a straight back.

A feature of the knee chair is the redirection of the load from the lower part of the spine to the muscles of the legs, while maintaining the vertical position of the back, the shoulders remain straightened.

Doctors and orthopedists advise purchasing such a chair for schoolchildren and students who have to spend a lot of time sitting at their lessons.
