 a plurality of connecting seats are disposed on an outer periphery of the open-style elastic layer, 
 the one or more mattress layers are laid on an upper side of the open-style elastic layer, 
 multiple of insertion members or hanging members extend from around the one or more mattress layers, 
 the open-style elastic layer is fixed to the one or more mattress layers by plugging or hanging the multiple of the insertion members or the hanging members on the plurality of connecting seats, and 
 at least part of one or more side surfaces of the open-style elastic layer are not wrapped by the multiple of the insertion members or the hanging members. 
   
     
     
         2 . The elastic mattress according to  claim 1 , wherein the plurality of connecting seats are sleeved on the plurality of pre-compressed springs. 
     
     
         3 . The elastic mattress according to  claim 1 , wherein:
 a plurality of connecting structures are disposed around peripheries of the plurality of connecting seats,   two of the plurality of connecting structures are connected to each other or the two of the plurality of connecting structures are connected by a third member,   each of the plurality of pre-compressed springs is disposed with a corresponding one of the plurality of connecting seats, and   two adjacent pre-compressed springs of the plurality of pre-compressed springs are connected by corresponding ones of the plurality of connecting structures.   
     
     
         4 . The elastic mattress according to  claim 1 , wherein:
 the open-style elastic layer further comprises a base plate,   the base plate abuts ends of the plurality of pre-compressed springs away from the one or more mattress layers, and   the plurality of connecting seats are disposed on the base plate.   
     
     
         5 . The elastic mattress according to  claim 4 , wherein:
 the multiple of the hanging members extend from around the one or more mattress layers,   the base plate is formed by twisting a thread,   the thread protrudes outwardly to form the plurality of connecting seats on an outer periphery of the base plate, and   the multiple of the hanging members are hung on the plurality of connecting seats.   
     
     
         6 . The elastic mattress according to  claim 4 , wherein:
 the base plate comprises a plurality of positioning posts protruding upward, and   bottoms of at least some of the plurality of pre-compressed springs are connected to the plurality of positioning posts by plugging.   
     
     
         7 . The elastic mattress according to  claim 1 , wherein:
 a surrounding edge is disposed around a periphery of the one or more mattress layers,   the surrounding edge is parallel to an elastic direction of the plurality of pre-compressed springs and wraps an upper end of a side surface of the open-style elastic layer, and   the surrounding edge extends downward to define the multiple of the insertion members or the hanging members or the multiple of the insertion members or the hanging members are fixed to the surrounding edge.   
     
     
         8 . The elastic mattress according to  claim 1 , wherein middle portions of two adjacent pre-compressed springs of the plurality of pre-compressed springs are connected. 
     
     
         9 . The elastic mattress according to  claim 1 , wherein the elastic mattress comprises multiple of the one or more mattress layers with different hardness. 
     
     
         10 . An application of the elastic mattress having the open-style elastic layer according to  claim 1 , comprising:
 applying the elastic mattress in a sofa, a bed mattress, an upholstered stool, or a camping mat.
