Abstract
A cushioning net structure having an apparent density of 0.005-0.20 g/cm.sup.3, which comprises three-dimensional random loops bonded with one another, wherein the loops are formed by allowing continuous fibers of 300 denier or more mainly comprising a thermoplastic elastomer to bend to come in contact with one another in a molten state and to be heat-bonded at most contact points, and a method for producing the net structure. The structure of the invention can provide unstuffy cushions superior in heat resistance, durability and cushioning property. The cushioning structure is advantageous in that it can be easily recycled.
