Description

Technical Field

[0001] The utility model relates to the field of chairs, in particular to a portable folding chair. Background Art

[0002] In family life or outdoor activities, people often need a chair to rest. In family life, non-foldable chairs cannot be folded to reduce the space they occupy like foldable chairs due to their fixed size and shape. This means that they need to occupy more physical space when stored. For people with limited living space, this may cause the furniture layout to become crowded, affecting the convenience and comfort of daily life; in outdoor activities, non-foldable chairs are often more cumbersome due to their size and weight. This not only increases the difficulty of carrying, but may also require additional transportation or manpower to assist. In contrast, foldable chairs can be easily folded into a smaller volume, which is easy to carry and transport; non-foldable chairs have poor flexibility in layout adjustment. In family gatherings, meetings or other occasions where flexible adjustment of the layout of tables and chairs is required, non-foldable chairs may limit the diversity of venue layout. For example, when seats need to be added or reduced quickly, foldable chairs can be quickly unfolded or folded, while non-foldable chairs may require more time and manpower to move and adjust.

[0003] However, the existing folding chairs are not sufficiently supported, resulting in insufficient support for the back and buttocks when used for a long time. This may make the user feel tired or uncomfortable. When used on uneven ground, the instability of the existing folding chairs may affect the user's sitting posture and comfort, and may even cause safety risks. Therefore, how to design a comfortable portable folding chair that can be folded quickly and has strong stability has become an urgent problem that technicians in this field need to solve.
