PROBLEM TO BE SOLVED: To provide bedding using a three-dimensional random loop joint structure of a continuous linear body, which is bedding excellent in cushioning property and quietness.SOLUTION: Bedding includes: a three-dimensional random loop joint structure obtained by forming random loops by winding a continuous linear body comprising a thermoplastic resin, bringing each loop into contact mutually in the molten state, and fusing the most part of contact parts; and a package for packaging the three-dimensional random loop joint structure. The apparent density of the three-dimensional random loop joint structure is 0.005-0.200 g/cm3, and the number of junctions per unit wight of the three-dimensional random loop joint structure is 500-1,200/g. |
