Abstract

A permanently steady safety chair is provided. A forward end of a left side beam floor support (41) and a forward end of a right side beam floor support (42) are fixedly connected with a left front leg (31) of a left front leg assembly and a right front leg (32) of a right front leg assembly respectively. The middle sections of the left and right side beam floor supports (41, 42) are fixedly connected with lower ends of a left back leg (21) and a right back leg (22) of a backrest assembly respectively. The back ends of the left and right side beam floor supports (41, 42) touch the floor and come into being a support. The above solution makes the pivot point move backwards when the chair inclines backwards, such that the possibility of backward overturn is reduced, even if the chair is placed on a slope with small gradient, for example, not more than 15 degrees. Moreover, the whole chair is broken into a seat board assembly, a backrest assembly, a left/right front leg assembly and a left/right side beam floor support assembly by four-section-packaging, such that packing material, packing volume and logistics cost are effectively saved.
