Today, not only office employees work at the computer, but also schoolchildren, students, housewives. Because of the wrong choice of an armchair the spine deforms, pains appear in the sacrum and stagnation of blood in the small pelvis. Only the orthopedic chair does not worsen the state of human health, even with many hours of sedentary work. As one can understand from the title, this chair forms a posture and does not contradict the physiology of the organism, especially if it has orthopedic disorders. In a variety of models of the orthopedic chair, it is not difficult to get confused, if you do not know the purpose of creating each of them.
Types of chairs
Orthopedic furniture is divided into: preventive and corrective. The chairs of the first type are universally suitable for both children and adults. Correction chairs are an important element of treatment and inhibition of serious diseases of the musculoskeletal system. Among the varieties of orthopedic chairs for posture are distinguished:
- The seat is supported by the knees . The most inconvenient, but effective chair for people suffering from inflammation of the pelvic organs, varicose veins and radiculitis. The chair with a soft roller under the buttocks transfers most of the load from the lower back to the knees, resting on the second roller. This chair artificially forces the spine to take the maximum natural deflection.
- Saddle . It relieves stress in the sacrum, but it loads the upper spine due to the lack of a full back. The seat-saddle has an anatomical recess for the buttocks and a protrusion in the front that prevents the narrowing of the vessels in the region of the thighs. The chest rises in the rider's position, so a large amount of air enters the lungs. In the stool-saddle patients with asthma and chronic bronchitis are needed.
- Seat with hinges . This is a children's and teenage orthopedic chair on reliable hinges or a special cushion made of durable material. Movable chair forces the child to keep balance constantly and follow the posture, as during the sports training. It reliably lays the foundation for a healthy development of the spine and pelvis. In adults, this need may exacerbate existing problems with the vertebral column;
- Gaming and ergonomic chairs for the computer . Gamers, freelancers, programmers need special chairs, as they spend a sitting full-time non-standard working day.
How to choose an orthopedic chair for a computer?
The chair in which you work should not just be orthopedic. It is important to take into account the comfort of the backrest and seat cover, the wear of the mechanisms and the frame. Take into account that it will have to be spent on it - furniture with a reliable metal supporting structure can not be cheap. The characteristics of an ergonomic chair include:
- support of the lower lumbar spine . The chair should have a height adjustment of the backrest and the angle of inclination. The back should not be soft: thanks to its elasticity, the person sitting does not have to stoop;
- breathable backrest fabric . Orthopedic chairs are often covered with polyurethane fabric, creating an imitation of artificial leather. Touching the back, it creates a greenhouse effect, provoking sweating. The backing covering should consist of polyester mesh textile, conductive liquid;
- Adjustable armrests . They can not be considered an additional option: without armrests it is impossible to work productively at the computer. They also need to be adjusted in height to relieve tension in the wrists;
- lifting mechanism with convenient lever . Shock absorbers are the most problematic part of any chair. The springs and screws of the structure should not be made of plastic that can not withstand the weight of a person.
