Description

A foldable and deformable lunch break chair

Technical Field

The utility model relates to the technical field of lunch break chairs, in particular to a foldable and deformable lunch break chair.

Background Art

In recent years, many students stay in school at noon. Due to the lack of adequate dormitories for rest, most students can only lie on their seats to rest, which will affect the students' study of afternoon courses. At the same time, due to too much time lying on their seats to rest, the pressure on the students' cervical spine will be aggravated, affecting the healthy growth of students. In order to enable students to have a good lunch break, various items such as pillows for rest have appeared on the market, but these items such as pillows cannot fundamentally enable students to get enough rest. Therefore, there is an urgent need for a tool that can enable students to take a lunch break in the classroom. The existing part of the foldable chairs is only for the convenience of transportation of chairs. After the foldable tables and chairs are fixed, there is no place for students to take a lunch break. Therefore, it is not suitable for students in the current situation. When the existing part of the chairs are unfolded for sleeping, not only is the support unstable, but the center of gravity is also high, which poses a great safety hazard.
