       7 . The trampoline stairway device of  claim 1 , further comprising a landing support member with plurality of interlock arms, wherein each said riser comprises a base receiving port for receiving at least one interlock arm of said plurality.  
   
   
       8 . The trampoline stairway device of  claim 1 , wherein said plurality of treads is three treads upwardly carried by and between two said risers defining three steps.  
   
   
       9 . The trampoline stairway device of  claim 2 , wherein each said step railing further comprises a plurality of strap receiving ports proximate the top edge thereof, wherein a pair of webbed safety nets are removably secured thereto.  
   
   
       10 . A portable, modular stairway system, comprising: 
 a pair of risers, each defining a step portion and a landing portion;    a pair of railings carried proximate said step portion of said risers;    a landing platform; and    a plurality of treads,    wherein each said riser, railing, landing platform and tread is twin sheet, thermoformed plastic, and wherein each riser interlockingly couples to said landing platform, said treads, and said railing.    
   
   
       11 . The portable, modular stairway system of  claim 10 , further comprising a gate, said gate hingedly extending between said railings.  
   
   
       12 . The portable, modular stairway system of  claim 10 , wherein at least one twin-sheet thermoformed component is comprised of fill-apertures for receiving ballast therein.  
   
   
       13 . The portable, modular stairway system of  claim 10 , further comprising a plurality of aluminum support poles carried by a plurality of twin sheet thermoformed components.  
   
   
       14 . A method of assembling a stairway and landing device, comprising the steps of: 
 a) obtaining a pair of risers, a landing, a landing support member and three stair treads;    b) interlocking a first riser in a perpendicular relationship with said landing support member;    c) interlocking a second riser in a perpendicular relationship with said landing support member;    d) interlocking a first end of a first stair tread with said first riser;    e) interlocking a second end of said first stair tread with said second riser, defining a first step;    f) interlocking a first end of a second stair tread with said first riser;    g) interlocking a second end of said second stair tread with said second riser, defining a second step;    h) interlocking a first end of a third stair tread with said first riser;    i) interlocking a second end of said third stair tread with said second riser, defining a third step;    j) interlocking a first end of said landing with said first riser; and    k) interlocking a second end of said landing with said second riser, defining a landing.    
   
   
       15 . The method of  claim 14 , further comprising the step of: 
 l) filling at least one said riser, tread, or landing support member with a ballast material.    
   
   
       16 . The method of  claim 14 , further comprising the steps of: 
 l) obtaining a pair of hand rails; and    m) installing said hand rails through said treads and into said risers.    
   
   
       17 . The method of  claim 16 , further comprising the steps of: 
 n) obtaining a hinged gate; and    o) installing said hinged gate between said hand rails.    
   
   
       18 . The method of  claim 16 , wherein each said hand rail comprises a plurality of apertures adapted to receive a soft safety guard therethrough.  
   
   
       19 . The method of  claim 14 , A method of assembling a stairway and landing device, further comprising the steps of: 
 a′) obtaining a plurality of aluminum support members;    c′) inserting three aluminum support members of said plurality of aluminum support members into said first and second risers; and    i′) cross-positioning at least one aluminum support member of said plurality of aluminum support members between said first and second risers.    
   
   
       20 . The portable, modular stairway system of  claim 10 , further comprising: 
 a plurality of rigid, straight tube members; and    a plurality of rigid H-shaped support members,    wherein said plurality of rigid, straight tube members are positioned between said risers and said landing platform and wherein said plurality of rigid H-shaped support members are positioned within and between said risers and said railings, passing through said treads.
