Technical Field
[0001] The utility model relates to the technical field of outdoor seats, in particular to an aluminum outdoor seat with a telescopic footstool structure. Background Art
[0002] As life gets better, more people go outside to enjoy life comfortably, and the requirements for outdoor equipment are getting higher and higher. Park chairs are a kind of outdoor product for passers-by to rest, mostly used in parks, communities, large playgrounds, shopping malls, and public places. With the development of the times, park chairs have entered most small and medium-sized cities and become a beautiful landscape of the city. It has brought convenience to people and made the environment more harmonious. Most park chairs are composed of two parts: chair bars and chair legs.
[0003] Traditional outdoor park chairs have a single function, especially the waist, which cannot be adjusted according to needs. Some outdoor chairs can change the sitting position, but lack footstools, so when half-lying or lying, the feet are still in a sitting position, making it difficult for users to reach a comfortable state.
[0004] Based on this, this scheme proposes an aluminum outdoor seat with a retractable footstool structure. Utility Model Content
