A foldable cloth-embedded bleacher seat has two symmetrical armrest assemblies, a backrest assembly, a cushion assembly and a hook assembly. The backrest assembly has a detachable backrest cloth. The cushion assembly has a detachable cushion cloth cover. A lower part of each of the two sides of the backrest assembly is rotatably connected to the upper side of one armrest assembly, and the bottoms of the two sides of the backrest assembly are rotatably connected to the two sides of the cushion assembly. The lower sides of the two armrest assemblies are rotatably connected to the two sides of the cushion assembly. The hook assembly is detachably installed on the lower surface of the cushion assembly. The bleacher seat is foldable, thereby occupying a small space and being simple, attractive, elegant, firm and durable in overall structure, and convenient and fast to fold and unfold.

The invention discloses a lightweight folding chair, comprising a chair seat and a bottom bracket assembly; the assembly comprises a frame member in the middle that comprises left rear, right rear, left front, and right front connectors, and rear, left, front, and right horizontal tubes that sequentially connect the left rear, right rear, left front, and right front connectors together; a backrest tube is connected to each upper end of the left rear and right rear connectors through the elastic cord; an upper support tube is connected to each upper end of the left front and right front connectors through the elastic cord. The angle of the leg tube is small and the stress is good during use; after the invention is folded, the components are brought close together, the folded volume is smaller, which does not occupy much space and is more convenient to be carried and transported.
