1. Apparatus for use in repetitive bouncing to improve blood and lymphatic solution circulation, the apparatus comprising(a) an inflated platform, that consists of flexible elastomeric material defining a hollow interior in which pressurized gas is received,(b) the platform having a central upper wall and there being a reinforced layer on said upper wall on which to stand, during bouncing, the platform having an annular top wal at substantially higher level than said layer, and a bottom wall beneath said upper wall,(c) the platform having a side wall which integrally merges with said top and bottom walls, and which is reinforced to resist outward expansion during bouncing, the annular top wall merging with said central upper wall,(d) said side wall being everywhere openly and unobstructedly exposed to all of said hollow interior below said upper central wall and above said bottom wall, and also below said annular top wall,(e) there being a flat reinforcement layer on and covering said central upper wall,(f) the platform being deflectible and frameless, the platform defining an upwardly opening recess immediately above said upper layer, the depth of said hollow interior below said central wall being sufficient to prevent bottoming of said wall during bouncing,(g) the platform annular side wall having associated glass fiber reinforcement, the thickness of said side wall and reinforcement substantially exceeding the thickness of each said top and bottom walls, and a gas fill valve in said side wall near said bottom wall.
