       10 . The baby jumper as claimed in  claim 9 , wherein said first annular part further includes an annular protruding rim formed at an inner top edge of said annular track, and a plurality of ball bearings embedded in said annular protruding rim for contacting said top flange of said seat mount. 
   
   
       11 . The baby jumper as claimed in  claim 5 , wherein each of said elastic couplers includes:
 a biasing member having first and second biasing ends;   a first anchoring member for connecting said first biasing end to said top frame; and   a second anchoring member for connecting said second biasing end to said seat support.   
   
   
       12 . The baby jumper as claimed in  claim 11 , wherein said biasing member is an extension spring, each of said elastic couplers further including a sheath sleeved on said biasing member. 
   
   
       13 . The baby jumper as claimed in  claim 11 , wherein each of said elastic couplers further includes a connecting strap for connecting said first anchoring member to said top frame, and a mounting piece mounted fixedly on said seat support and connected to said second anchoring member. 
   
   
       14 . The baby jumper as claimed in  claim 11 , wherein said first annular part includes an annular track with a U-shaped cross-section, said second annular part having an inverted-L shaped cross-section and engaging slidably said first annular part such that said seat unit is rotatable relative to said seat support. 
   
   
       15 . The stationary baby jumper as claimed in  claim 2 , wherein adjacent ones of said elastic couplers are angularly spaced apart by an angle of 120 degrees. 
   
   
       16 . A baby jumper comprising:
 a support frame assembly including
 a top frame, 
 a plurality of legs, each having a top end connected to said top frame, and 
 a plurality of elastic couplers, each of which has a first end connected to said top frame, and an opposite second end; and 
   a seat assembly connected to said second ends of said elastic couplers, said seat assembly including
 a seat support having a first annular part that defines a seat hole, and 
 a seat unit disposed in said seat hole and having a second annular part that engages slidably said first annular part such that said seat unit is rotatable relative to said seat support. 
   
   
   
       17 . The baby jumper as claimed in  claim 16 , wherein said seat unit includes:
 a child seat formed with a pair of leg openings;   a seat mount formed with said second annular part; and   a set of fasteners for fastening said seat mount to a periphery of said child seat.   
   
   
       18 . The baby jumper as claimed in  claim 17 , wherein:
