A recreational device for producing the thrill of a series of consecutive free falls, which includes a housing, a shock absorbing cushion throughout the bottom of the housing, an inwardly extending peripheral deck near the top of the housing arranged to provide a launching platform for allowing persons to jump into the housing, and a plurality of horizontal planar non-woven nets of elastic bands arranged at different levels within the housing with each net spanning the whole horizontal cross-section of the housing. The elastic bands are randomly arranged within each individual net so as to leave spans between the bands which are insufficiently small to prevent a person from passing through the nets without bouncing on each consecutive net, the elastic bands having an elasticity sufficient to permit persons to manually space the bands to jump from a higher net of bands to a lower net of bands. Each of the horizontal planar non-woven nets are constituted by from 2 to 4 levels of elastic bands, the levels being closely spaced from each other within an individual net to permit the reinforced bouncing of heavy persons whose weight or height of fall may deflect the upper ones of the band levels in an individual net beyond a permissible tolerance.
