How to remove a gas lift from an office chair

No office can work properly without a certain set of office furniture, which includes an office chair.

What does an office chair consist of?

Office chair, despite the external simplicity, is a rather complex product, which consists of many components. These include:

Back - designed to support the back, it can have different sizes and shapes. The angle between the seat and the back is a little more than 90 degrees and this ensures relaxation of the lower back when the back is thrown back to the back.

Most often, the back is equipped with a set of adjusting mechanisms that allow you to adjust the angle of inclination, setting it in a certain position and this will provide additional comfort for operating the chair.

Seat - Manufacturers produce several types of seats. Manufacturers produce the following models:

  • solid;
  • semi-soft;
  • soft.

Each seat may have a different filler. To fill the hard seats use straw, wood or metal. In semi-soft chairs, polymeric materials, for example, foam rubber, are often used for filling. In a soft seat, in addition to the filler, springs can be installed.

The front edge of the seat has a rounded shape, this ensures normal blood supply to the legs. Most often, manufacturers make seats with a width of 400 to 500 mm, a depth of 480 mm.

The following is considered the optimal position of the chair - the feet are located on the floor, while the legs are bent at the knees, the angle is 90 degrees. Hips should be tightly placed on the seat.

Armrests - designed to support the elbows, thus removing the load from the shoulders, neck and spine. Most often, a person needs such a lot of work for a long time working at a computer. Lack of armrests leads to fatigue and loss of performance.

Armchair manufacturers equip them with customizable armrests. In the event that it is not adjustable, then they guarantee a position where the arms are bent at the elbows at an angle of 90 degrees.

These parts can be attached to the backbone of the chair in various ways:

  • They can be attached directly to the seat. If necessary, they can always be dismantled without violating the integrity of the chair.
  • They are attached simultaneously to the back and seat, thus linking together.
  • The armrests are installed so that they connect the seat and back, but, in addition, a metal plate is additionally installed. For the most part, they can be removed without affecting the structure as a whole.

Upholstery - for this, materials with high wear resistance are most often used. It can be both natural and artificial materials, including the use of leather.

Filler - foam and other polymeric materials are used to fill the seats and backs.

Gas lifts, sometimes you can find the name gazpatron. They are divided into long, medium and short. All of these units have unified sizes and are interchangeable.

They are produced either with a chrome finish or painted in black. Painted elevators are equipped with a cover.

This design is able to provide ultimate maneuverability in all directions of movement. For its manufacture, both metal and plastic are used. The key disadvantage of a metal cross is overweight.

Manufacturers equip the seats with numerous mechanisms that allow you to adjust the chair in height and in reclining. All of them are designed to provide extremely comfortable conditions for humans.
