In terms of bed frame structure, there are grid folding type, multi-axis folding type, four-link double folding type, etc. Although the folding grid frame is small in size and easy to carry, it is not easy to operate due to the limitation of too many folding joints, and can only use soft chemical fiber, canvas and other materials for the bed surface; the multi-axis folding type , because there are many rotating mechanisms, it often needs to be folded multiple times to complete the operation of the product, and due to the complex structure, the product weight is also heavy; the traditional four-link two-folding type, although simple in structure and easy to operate, but due to its structure The excessively large span results in an excessively long moment arm at the middle stress position, which puts forward high requirements on the strength of product materials and structural parts, which in turn causes the product to be too heavy and inconvenient to carry.

There are three main types of bed surface materials: one is chemical fiber, canvas and other textile materials. Chemical fiber materials are light in weight, small in size and low in price. Long-term use will cause discomfort in the waist of the personnel, reduce the comfort of the personnel, and seriously affect the physical fitness of the personnel; the second is aluminum alloy and other metal materials, which are light in weight, easy to carry, flat on the bed surface, comfortable in summer, but expensive and poor in air permeability , in winter, the heat loss to the human body is large and the cold feeling is strong; the third is to use wood, bamboo and other plant materials. It is damp and prone to insects, so it is not suitable for carrying and long-term use in the field.

Therefore, researching a portable folding bed that is light in weight, easy to operate, breathable and moisture-permeable, comfortable to use, mildew-resistant, rot-resistant, insect-resistant, environmentally friendly, and affordable is a problem that outdoor camping equipment has always sought to solve.
