To provide an easily recyclable cushion body of a three-dimensional mesh structure.

This cushion body 1 includes a mesh cushion material 3 having a three-dimensional random loop mesh structure, and framing wires 4 fixed to the mesh cushion material 3 by clips 5. The mesh cushion material 3 has a three-dimensional mesh structure with an apparent density of 0.005 to 0.2 g/cm3, in which a number of continuous linear elements 2 made from a thermoplastic resin and having a fineness of 300 to 100,000 denier are twisted like loops and have their contacting parts fused together. The clip 5 has a framing wire attaching part, an insertion part consisting of a pair of arms each having a width smaller than the outside diameter of the framing wire 4 and having a pointed end, and a locking part projecting outward from each side of the insertion part and pointed to the framing wire attaching part. The locking part is hooked to a portion of the three-dimensional random loop continuous linear body 2 of the mesh cushion material 3, whereby the framing wires 4 are fixed to the mesh cushion material 3.
