Each part of an existing chair formed in a single structure is formed in a dual structure for reducing various kinds of impediments such as non-economic, non-environmentally friendly, unsanitary, inefficient, and non-available properties caused in a method for manufacturing existing chairs such as office chairs, sofas, rail motor seats for disabled, and vehicle seats, in a usage process after manufacturing, and in a discarding process after use. A new elastic force is performed as a gas spring device and a pressure elastic structure are attached to both sides of the structure. The structure of a sitting cushion used by placing on a stand unit such as the chair and a stand equal to a stand placed on the stand unit is formed in an ergonomical shape for user convenience and each part of the existing chair and the structure of the sitting cushion are transformed and improved for preventing environmental pollution. |
