Title: Mattress with adjustable hardness and comfort levels

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority under 35 U.S.C. §119 to Indonesian Patent Application No. 500201605162, filed Aug. 5, 2016, the disclosure of which is incorporated by reference herein in its entirety. 
     FIELD OF INVENTION 
     The present invention relates to a mattress where the hardness and comfort levels can be adjusted by a user by changing the arrangement of the mattress layers on the left and right sides of the mattress. 
     BACKGROUND OF INVENTION 
     The mattress has become an essential requirement for people. The consideration is the people need a mattress that can provide a comfort and getting a better quality of sleep. 
     Currently there are various types of mattresses available with soft, hard and even very hard characteristics. Many consumers are eventually confused when choosing and purchasing the right mattress, particularly in terms of selection of mattress hardness level that may provide comfort for himself and/or his spouse. 
     Errors in buying a mattress are generally happening for example, the mattress is too hard or too soft therefore it does not provide an appropriate comfort for the users. This certainly causes its own problems. A mattress had been purchased usually could not be exchanged, refunded, changed or to be set for the hardness level. To sell and buy back a new mattress will not be an effective and efficient problem solving because the consumers will have to spend additional costs. 
     It should be understood that each human being has a different body profile, likewise with each other spouse in regards to the mattress. Someone may require a mattress with more hardness level than needed by the spouse, but the mattress products available today only provide the same hardness level on both sides of the mattress. Thus as a result, one of the users of a mattress may feel uncomfortable when sleeping because the hardness level of mattress does not fit with his/her body profile. Furthermore, the changing needs for the hardness level of a proper mattress for him and/or his spouse may be caused by age, health, pregnancy, body weight, injuries, and other factors. The mattresses which were once initially fit may no longer be appropriate because of those changes. 
     SUMMARY OF INVENTION 
     In view of the foregoing, the present invention relates to a mattress with adjustable hardness and comfort levels by the user thus able to provide more comfortable sleeping. 
     The mattress with adjustable hardness and comfort levels comprises a surface cover layer, a first comfort layer, a second comfort layer and a hollow frame made of foam at the bottom. 
     This mattress provides flexibility for consumers to change the arrangement of layers in the mattress (i.e., comfort layers) to achieve a desired hardness level according to one&#39;s body profile independently for the users on the left and right sides of the mattress. Consumers can also change the hardness level of their mattress easily as desired by opening the zippers, adhesive or buttons to adjust the comfort layers contained in the mattress anytime. 
     These comfort layers are independently separate parts on each side that would be used by the user; that is, on the left and right sides of the mattress. Thus, each user may adjust the most suitable hardness level against his/her body profile on each side of the mattress without affecting the hardness level of his/her spouse. 
     The adjustable comfort layers comprise one or more materials in the form of foam, latex, synthetic fibers, natural fibers, gel or spring materials that can be reversed and changed on the arrangements order among each other (if more than one layer) to produce the combination of most appropriate hardness and comfort levels according to the user&#39;s preferences. 
    
    
     
       BRIEF DESCRIPTION OF DRAWINGS 
       For a more complete understanding of the present invention, reference is made to the following detailed description of an embodiment considered in conjunction with the accompanying drawings, in which: 
         FIG. 1  is a perspective view of a mattress with adjustable hardness and comfort levels in accordance with an embodiment of the present invention; 
         FIG. 2  is an exploded view of the mattress shown in  FIG. 1  showing the structure of forming parts of mattress; and 
         FIG. 3  is a schematic view of the mattress shown in  FIG. 1  illustrating the arrangement of hardness and comfort levels when it will be used for two people. 
     
    
    
     DETAILED DESCRIPTION OF INVENTION 
     Referring to  FIG. 1 , a mattress  10  is shown with a hardness level that can be adjusted by a user in a position already arranged and closed by a surface cover layer  12 . 
     Referring to  FIG. 2 , the structure of the mattress  10  is shown, wherein layers of the mattress  10  having hardness levels can be adjusted by the user in the open position. The mattress includes a hollow frame  14  made of foam. The hollow frame  14  is filled with a first comfort layer  16  and a second comfort layer  18  where the placements of layers are interchangeable and may be reversed. The comfort layers  16 , may have different levels of hardness, thus, when the arrangement is changed and their surfaces are reversed, it will produce a different overall hardness and comfort level. 
     Referring to  FIG. 3 , a large mattress  20  is shown (for example, the mattress size is 2 meters×2 meters) when used for two people. Each of the left and right sides of the mattress  20  has its own surface cover layer  22 , first comfort layer  26  and second comfort layer  28 , allowing the hardness and comfort levels on each side to be different. The surface cover layer  22  is a layer or cover panel of mattress surface used by the user and it can be opened partially or entirely thus the user can take and arrange the comfort layers (B) and (C). 
     In these embodiments, the first comfort layer  16 ,  26  and the second comfort layer  18 ,  28  can be made from foam, latex, synthetic fibers, natural fibers, gels or spring materials. 
     In these embodiments, the installation of the surface cover layer  12 ,  22  to the hollow frame  14 ,  24  can be made of foam can use Velcro, zippers or buttons adhesives. 
     It should be noted that without departing from the initial and scope of the invention, the implementation of the embodiments of the present invention is not limited to the shape, size, dimensions, models, and the placement of arrangements order. The embodiments described above are merely illustrative to clarify the present invention.
