     FIELD OF THE INVENTION 
     An adjustable mattress system for providing customized levels of support and comfort is disclosed. 
     DESCRIPTION OF THE BACKGROUND 
     Many attempts have been made to make adjustable mattress inventions. Most common are the adjustable mattresses having one or more air chambers and a pump for bringing in air to inflate or deflate the one or more chambers in order to adjust the firmness of the mattress. Such mattresses suffer from deficiencies, however, typically relating to the air slowly leaking out of the chambers, thereby causing the sleeper to wake up throughout the night and refill the mattress chambers with air. 
     SUMMARY 
     In accordance with one form of the present invention, there is provided an adjustable mattress system has a main body with a plurality of cushioning layers extending the length of the main body and attached atop one another to provide customizable support to a person on top of the mattress system. The main body has a top, bottom, and four sides, and is composed of at least three individual layers. The adjustable mattress system also includes a cushioning topper that is detachably coupled to either the top or the bottom of the main body when the adjustable mattress system is deployed. 
     In accordance with another form of the invention, there is provided an adjustable mattress including a cover; a main body including a first cushioning layer, a second cushioning layer, and a third cushioning layer; the first cushioning layer being attached to the second cushioning layer and the third cushioning layer being attached to the second cushioning layer, each of the first, second and third cushioning layers extending approximately the length and width of the main body; the first cushioning layer being formed from foam; the second cushioning layer being formed from high-density core foam; the third cushioning layer being formed from foam; and wherein the top surface of the first cushioning layer forms the first surface of the main body and the bottom surface of the third cushioning layer forms the second surface of the main body; a topper that is selectively coupled with the first surface of the main body or the second surface of the main body, the topper extending approximately the length and width of the main body; and wherein the cover is sized and configured to receive the main body and topper. 
     In accordance with another form of the invention, there is provided an adjustable mattress including a cover; a main body including a first cushioning layer, a second cushioning layer, and a third cushioning layer; the first cushioning layer being attached to the second cushioning layer and the third cushioning layer being attached to the second cushioning layer, each of the first, second and third cushioning layers extending approximately the length and width of the main body; the first cushioning layer being formed from foam; the second cushioning layer being formed from high-density core foam; the third cushioning layer being formed from foam; wherein the top surface of the first cushioning layer forms the first surface of the main body and the bottom surface of the third cushioning layer forms the second surface of the main body; a topper extending approximately the length and width of the main body; and wherein the cover is sized and configured to receive the main body and topper in any one of a plurality of configurations including a first configuration defined by the main body being oriented such that the second surface is at the top of the main body and the topper is coupled with the first surface of the main body; a second configuration defined by the main body being oriented such that the second surface is at the top of the main body and the topper is coupled with the second surface of the main body; a third configuration defined by the main body being oriented such that the first surface is at the top of the main body and the topper is coupled with the second surface of the main body; and a fourth configuration defined by the main body being oriented such that the second surface is at the top of the main body and the topper is coupled with the second surface of the main body.

     DETAILED DESCRIPTION 
     In accordance with one form of the present invention, there is provided an adjustable mattress system including a main body having a top, bottom, and four sides, and having a plurality of layers of the same or different thicknesses and/or densities; a topper layer that is positioned either on top of or beneath the main body; and a removable cover that may encase the main body and topper according to multiple configurations. 
       FIG. 1  is an illustration of an embodiment of an adjustable mattress system, which includes a main body  20  composed of a plurality of layers  12 ,  14 , and  16 . Each of the plurality of layers  12 ,  14 , and  16  is generally the same length and width, but may be of different thicknesses and/or densities. Also included is a topper  18 , which is of generally the same length and width as main body  20 , so that it is congruent with main body  20 . Topper  18  may be of a thickness and/or density that is different than or the same of at least one of layers  12 ,  14 , or  16 . Topper  18  is configurable to be selectively positioned beneath the main body  20  or on top of the main body  20 , depending on the configuration of the adjustable mattress system. The main body  20  and topper  18  may be detachably coupled by the use of straps, hook and loop fasteners, zippers, snaps, an outer cover, or other similar means of attachment. 
     For convenience of illustration, a removable mattress cover  22  is omitted from  FIG. 1 , but is shown in one embodiment in  FIG. 6 . Cover  22  encases the main body  20  and topper  18  when the adjustable mattress system is deployed in a configuration. In one embodiment, the cover  22  fits snugly around the main body  20  and topper  18  to hold those two pieces together when the adjustable mattress system is in use. 
     Cover  22  may be constructed of a machine washable or similar fabric and may include a non-slip bottom to partially secure the adjustable mattress system on a surface. Cover  22  may have a zipper  24  or other similar means of closing the cover around main body  20  and topper  18 . The zipper  24  or other means of closure may span the entire perimeter of cover  22  or only a portion of cover  22 . In addition, the fabric of cover  22  may be wholly or partially constructed of a stretchable or elastic material in order to ease the task of inserting the main body  20  and topper  18  into the cover, and/or the fabric may be partially or wholly constructed of a durable fabric to provide protection to the main body  20  and topper  18 . The inner surface of the cover  22  may be comprised of a fire-retardant material or composition. It will be appreciated that in any of the embodiments disclosed, the adjustable mattress system may be deployed with or without cover  22  without generally departing from the benefits and functions of the disclosed invention. 
     In one embodiment of the invention, the thin layer  12 , medium layer  14 , and topper  18  may be composed of memory foam, high-loft foam, and/or other similar materials. Core layer  16  may be composed of firm, high density foams, a framework of springs, rubber, air, water, and/or other similar materials. It will be appreciated that other types of foams or cushioning may be employed without departing from the goals and benefits of the invention. It will be further appreciated that a combination of materials of varying thicknesses and densities may be employed for each of the described layers. 
     According to one embodiment, main body  20  has three layers: thin layer  16 , medium layer  12 , and core layer  14 . The layers may be permanently attached to one another by glue, adhesive, or other similar attachment means to form the main body  20 . Core layer  14  is positioned between thin layer  16  and medium layer  12 . Thin layer  16  and medium layer  12  may be composed of a high loft memory foam to provide a responsive, contouring surface. Core layer  14  may be composed of a more dense, high-density foam base to provide a firmer structure in between the thin layer  16  and medium layer  12 . Topper  18  may be composed of a memory foam similar to that of thin layer  16  or medium layer  12 . A fire-retardant coating may surround main body  20 , topper  18 , and/or individual layers  12 ,  14 , and  16 , or each individual component may have a dedicated fire retardant cover. 
     According to one embodiment, the layers of main body  20  may be detachably coupled to one another via hook and loop fasteners, snaps, straps, or other similar attachment means. A user is able to detach layers  12 ,  14 , and  16  from one another and rearrange the layers to form a customizable layering system of main body  20 . 
       FIG. 2  is an illustration of a first configuration of an adjustable mattress system. This embodiment is configured to provide an extra firm surface on which a person may lie. In this first configuration, the main body  20  is oriented so that the thin layer  16  is the topmost layer. Thin layer  16  is directly above core layer  14 , which in turn, is directly above medium layer  12 . Topper  18  is situated beneath the main body  20 , directly beneath medium layer  12 . Cover  22  encases the main body  20  and topper  18 , as configured, to hold the topper  18  and main body  20  together, as well as providing protection to the main body  20  and topper  18 . A person may thus lie on the adjustable mattress system and be resting on thin layer  16 . Because the thin layer  16  is directly supported by a firmer core layer  14 , the user may experience an extremely firm surface. 
       FIG. 3  is an illustration of a second configuration of an adjustable mattress system. This embodiment is configured to provide a firm surface on which a person may lie. The level of firmness in this configuration is less than that of the first configuration but is more than that of the third and fourth configurations. In this second configuration, the topper  18  is the topmost layer and is positioned on top of the main body  20 . The main body  20  is oriented beneath the topper  18  so that the thin layer  16  is beneath the topper  18 . Thin layer  16 , in turn, is directly above core layer  14 , which in turn is directly above the medium layer  12 . Cover  22  encases the topper  18  and main body  20 , as configured, to hold the main body  20  and topper  18  together, as well as providing protection to the main body  20  and topper  18 . A person may thus lie on top of the adjustable mattress system and be resting on topper  18 . Because the topper  18  and the thin layer  16  are used in combination above the core layer  14 , the user will experience a surface that is less firm than the first embodiment, but is more firm than the embodiments in the disclosed third and fourth configurations. 
       FIG. 4  is an illustration of a third configuration of an adjustable mattress system. This embodiment is configured to provide a medium level of firmness: less firm than the first and second configurations, but firmer than the fourth configuration. In this third configuration, the main body  20  is oriented so that the medium layer  12  is the topmost layer. Medium layer  12  is directly above core layer  14 , which in turn, is directly above thin layer  16 . Topper  18  is situated beneath the main body  20 , directly beneath thin layer  16 . Cover  22  encases the main body  20  and topper  18 , as configured, to hold the topper  18  and main body  20  together, as well as providing protection to the main body  20  and topper  18 . A person may thus lie on top of the adjustable system and be resting on medium layer  12 . Because the medium layer  12  is supported by a firmer core layer  14 , the user will experience a surface that is softer than the first and second embodiments but is firmer that the embodiment disclosed in the fourth configuration.  FIG. 5  is an illustration of a fourth configuration of an adjustable mattress system. This embodiment is configured to provide an extra soft level of firmness: less firm than the first, second, and third configurations disclosed above. In this fourth configuration, the topper  18  is the topmost layer and is positioned on top of the main body  20 . The main body  20  is oriented beneath the topper  18  so that the medium layer  12  is beneath the topper  18 . Medium layer  12 , in turn, is directly above core layer  14 , which in turn is directly above the thin layer  16 . Cover  22  encases the topper  18  and main body  20 , as configured, to hold the main body  20  and topper  18  together, as well as providing protection to the main body  20  and topper  18 . A person may thus lie on top of the adjustable mattress system and be resting on topper  18 . Because the topper  18  and the medium layer  12  are used in combination above the core layer  14 , the thickest level of memory foam is available to insulate the user from the firm core layer  14 . The user will experience a surface that is softer than all of the above embodiments disclosed. 
     In an additional embodiment of the invention, the topper  18  is excluded from the configuration, and the main body  20  is used alone and oriented so that the medium layer  12  is the top layer. The core layer  14 , in turn, is directly beneath the medium layer  12 , and the thin layer  16  is directly beneath the core layer  14 . A person may thus lie on top of the adjustable mattress system and be resting on the medium layer  12 . 
     In an additional embodiment of the invention, the topper  18  is excluded from the configuration, and the main body  20  is used alone and oriented so that the thin layer  16  is the top layer. The core layer  14 , in turn, is directly beneath the thin layer  16 , and the medium layer  12  is directly beneath the core layer  14 . A person may thus lie on top of the adjustable mattress system and be resting on the thin layer  16 . 
     In an additional embodiment of the invention, the topper  18  may be used alone, excluding the main body  20 . A person may thus lie on top of the topper  18  alone. 
       FIG. 6  is an illustration of the adjustable mattress system, including a removable mattress cover  22 . The topper  18  and main body  20  (composed of layers  12 ,  14 , and  16 ) are encased inside cover  22 , and for convenience of illustration, topper  18  and main body  20  are not explicitly shown in  FIG. 6 . Cover  22  functions to provide protection to topper  18  and main body  20 , as well as hold topper  18  and main body  20  together. 
     In an exemplary embodiment, a topper  18  is composed of 1″ of memory foam, a thin layer  16  is composed of 1″ of memory foam, a core layer  14  is composed of 6.5″ of a high-density core foam, and a medium layer  12  is composed of 2.5″ of memory foam. The adjustable mattress system may have standard length and width dimensions that are generally classified as twin, full, queen, or king-sized mattress. It will be appreciated that different dimensions (including length, width, and thickness) may be employed without departing from the goals and/or benefits of the present invention. 
     It will be appreciated that in each of the embodiments disclosed, the adjustable mattress system, or its individual components, may be used with or without the removable mattress cover  22  without departing from the goals and/or benefits of the present invention. 
     The dimensions and materials specified herein are preferred, but not mandatory, and different dimensions or materials may be used, as desired or necessary for a particular environment. 
     Thus, an adjustable mattress system has been described which comprises a cover encasing a main mattress body and a mattress topper. The main mattress body is comprised of at least three layers of different thicknesses, including a thin layer, a medium layer, and a thick core layer. The thick core layer is located between the thin layer and the medium layer in the main mattress body. The mattress topper is of a thickness less than that of the core layer. A cover encases the main mattress body and the mattress topper. The main mattress body is flippable so that either side of the mattress can be used as a sleeping surface, and the mattress topper can be placed either on top of or below the main mattress body. The variety of configurations can be adapted to provide a customized firmness in the sleeping surface.
