Abstract
A trampoline comprises a trampoline sheet or mat supported around its periphery from a circumextending support structure by spring couplings, preferably a plurality of helical springs, under tension. The trampoline is provided with a net enclosure in which a generally circumextending net is mounted by respective sheaths on a plurality of poles coupled to the support structure and extending generally upright therefrom. In use, for the greater part of its height, the position of the net corresponds generally to the periphery of the support structure, while lower edge regions of the net are coupled to the periphery of the sheet or mat inboard of the support structure, thereby at least largely preventing a user from falling or treading upon the spring couplings or on an annular pad overlying said couplings, if present.
