The invention relates to a double-layer trailer which comprises a first stand column, a second stand column, a third stand column, a fourth stand column, a first bottom supporting mechanism, a second bottom supporting mechanism and a plurality of folding mechanisms. The first stand column, the second stand column, the third stand column and the fourth stand column are arranged at intervals in a rectangular mode, the lower ends are connected with the first bottom supporting mechanism, and a folding mechanism is connected between every two adjacent stand columns and can be folded and contracted. The first stand column, the second stand column, the third stand column and the fourth stand column are all connected with the second bottom supporting mechanism, the second bottom supporting mechanism is located above the first bottom supporting mechanism, and the first bottom supporting mechanism and the second bottom supporting mechanism can be folded and contracted upwards. The first bottom supporting mechanism forms a first layer of trailer structure, so that articles with irregular sizes or large sizes can be conveniently placed. And the second bottom supporting mechanism is matched with the folding mechanism to form a trailer structure of a second layer, so that a cloth bag is conveniently arranged for containing small articles, and the small articles are prevented from falling off.
