We care about your health!

We, Ev tool OÜ, are engaged in the development and production of ergonomic chairs. We are located in Estonia and have been working on this topic for 7 years. The difference between our chairs and all existing types of ergonomic chairs is that sitting on our chairs brings benefits to the body. And especially children of school age. The idea of our development (Equilibrium point system) was given by a professional doctor who dealt with problems of the musculoskeletal system.
Ordinary, and created for people with back problems, chairs are made according to the principle – minimal energy consumption. But this is not always good. Modern man suffers from hypodynamia, which leads to metabolic disorders, diseases of the heart, blood vessels, spine, etc. The EP system technology creates conditions for efficient work of a person with maintaining physiological energy consumption, necessary for maintaining health.
Differences between EPS chairs and regular chairs The difference between a chair with EPS technology and a regular standard chair, which we all know, is:

First
Shortened backrest – why is it needed when sitting on chairs with a high backrest is easy and comfortable? When resting on a high backrest, the muscles that hold the spine do not strain, and, as it seems to us, we rest. But it is known that if a muscle does not work for a long time, it weakens and atrophies. The correct posture is mainly formed by the spine and the muscles surrounding it. Some muscles are short, they are attached between two adjacent vertebrae, and their function is to keep adjacent vertebrae straight, without skewing. These muscles are also called – safety muscles. Other muscles are long, they are attached through 4 vertebrae or more, they provide mobility. The joint work of these muscle groups provides the human spine with both safety and mobility. Researchers have noted that the function of short muscles is impaired when a child sits for a long time with support on a high backrest of a chair or armchair. Long muscles retain their ability to work, but left alone, they cannot keep the vertebrae straight without skewing. This is why the vast majority of modern high school students have posture disorders and scoliosis. These same small pathological skews, often invisible to the eye, lead to muscle overload, impaired blood flow, disc deformation and other mass problems with the spine in adulthood. If you have to sit a lot, in order not to impair the performance of the safety muscles of the spine or restore their function, you need to sit on chairs with a shortened backrest that fixes only the sacrum, not blocking the work of the higher joints, ligaments and muscles of the spine.

Second
The angle of inclination of the backrest relative to the seat is less than 90 degrees, this design allows you to fix the sacrum in the correct position, due to which the physiological bends are preserved in all sections of the spine.

Third
Dynamic seat or in other words, rocking. Due to this design feature of the chair, the following goals are achieved. Dynamic attachment of the seat provides a variety of loads on the paravertebral muscles and thigh muscles, which reduces hypodynamia and activates blood flow. The given amplitude of movement of the seat provides a person with the opportunity to make small inclinations forward, as a result it is more convenient to work at a desk, better posture and less fatigue at the end of the working day. Pediatricians have long noticed – when a child does homework, tilting the chair forward, his back remains straight, which means that he develops a good even posture, which will remain for life and not only decorate him, but also help avoid serious problems with the spine. The seat has two fixed positions. This design feature allows you to use the chair every full working day and not experience discomfort. No matter how a person sits on a chair with EPS technology, on the edge or with support on the backrest, with a tilt forward or straight, the chair provides correct posture. The dynamic seat provides a variety of loads on the paravertebral muscles and thigh muscles, which reduces hypodynamia and activates blood flow, and the shortened backrest restores and maintains the performance of functional elements of the spine.

The benefits of Equilibrium Point System chairs

Teaches you how to sit correctly.
The unique property of the new design is that if a person sits incorrectly – he is uncomfortable, trying to find a comfortable position, he involuntarily takes the correct posture, that is, the load on the elements of the spine is distributed harmoniously, without risk to health.
Activates blood flow and reduces static tension.
Normally, our body always makes micro-movements, due to which there is an alternation of activity – some muscles work, others rest, and vice versa. Such alternating muscle tension provides the body with good blood flow. The dynamic design of the EPS chair meets the need for movement, while maintaining correct posture.

Trains and restores muscles responsible for spine health and good posture formation.
When using standard furniture equipped with many supporting elements, joints, muscles and ligaments do not receive the load necessary for their proper functioning. As a result – impaired blood flow, atrophy, problems with the spine, rapid fatigue and other “gifts” from a sedentary lifestyle. The new design of the chair will serve as an excellent simulator for you, both at home and at work, study. You sit comfortably on the EPS chair, doing business, and at the same time strengthen your body, restore the work of the spine and at the end of the day get less tired. Provides passive seating comfort.
Movement is life, but excessive load is another extreme to remember. It is difficult to ride all day long, just as difficult to sit on a chair that has no neutral zone. The seat of the EPS chair has two fixation points: a horizontal position – familiar to us, and a position with a tilt forward. This meets the requirements of passive ergonomics and provides passive seating comfort.
Safety of movement and increased strength of the structure.
British scientists have proven – rocking is good. On chairs and armchairs EPS rocking occurs at a given optimal amplitude, while the chair will serve you as long as possible, as the rocking mechanism is an element of the structure.

Our mission is to benefit society. In designing and manufacturing, we adhere to the concept of accessibility of our products to the maximum layers of the population.
