Cushion structure

Abstract

This invention is a buffer structure, which is mainly formed integrally from a support unit, a first tension unit, and a second tension unit. By designing the first tension unit and the second tension unit respectively on the upper and lower end faces of the support unit, and by combining the design of the first upper tension strips of the first upper tension layer and the second upper tension strips of the second upper tension layer being in opposite directions, and by combining the design of the first lower tension strips of the first lower tension layer and the second lower tension strips of the second lower tension layer being in opposite directions, the buffer structure can provide uniform support force after being subjected to force, reduce local pressure points, and improve structural stability, support, resilience, and comfort.
