Abstract
Cushioning net structures comprise random loops, such as three-dimensional random loops, bonded with one another, wherein the loops are formed by allowing continuous fibers, made of ethylene/α-olefin interpolymers, to bend to come in contact with one another in a molten state and to be heat-bonded at most contact points. The structures provided herein have desirable heat resistance, durability and cushioning property. The cushioning structures are used in furniture, vehicle seats etc.
