PROBLEM TO BE SOLVED: To provide a Futon which realizes a reduction in weight even though the Futon has the same thickness as a conventional one, has durability without being deformed in fatigue in spite of the use for years, and is comfortable to sleep by retaining a sufficient cushioning property and air-permeability. SOLUTION: At least a layer 12 of a space is provided between an upper Futon part 4 and a lower Futon part 5 which are covered with pouched Futon cloth 2. The layer of the space is constituted of a hollow net structural body 6 which has upper and lower surfaces 8, 9 made into honeycomb like flat surfaces 10 by weaving yarn 7 of a fiber and has a prescribed thickness formed by connecting between the upper and lower surfaces by a number of connecting yarns 11 in the vertical direction.
