CROSS-REFERENCE TO RELATED APPLICATION  
       [0001]     This application claims the benefit of U.S. Provisional Application No. 60/545,688, entitled “Provisional Patent Application for &#39;save My Bed” filed Feb. 18, 2004, which is incorporated herein by reference. 
     
    
     BACKGROUND  
       [0002]     If a mattress is not protected, then when the mattress gets soiled, it may stain, and such stains can be very difficult, if not impossible, to remove. If such an unprotected mattress continues to be soiled and stained, it can generate a permanent odor that creates an unpleasant and unhealthy sleeping environment and, eventually, the mattress will become unusable and will need to be replaced. Mattresses are expensive, and to have to replace them prematurely due to soiling and staining becomes very costly.  
         [0003]     Mattress pads have been around for a long time and are effective at helping protect a mattress from getting soiled or stained when a bedtime accident occurs (e.g. when a child wets his bed, when a child is sick in bed, when a person is incontinent and has a bedtime accident, etc.). However, such standard mattress pads can be inconvenient to use, cumbersome to deal with and difficult to change when most bedtime incidents occur—during the middle of the night. With a standard mattress pad, when an accident occurs during the middle of the night, the bed linens and mattress pad have to be removed and changed so the person in the bed can get back to sleep. Although the task of changing the bed linens and mattress pad may be quite simple and straight-forward during the day when no one is sleeping in the bed and there is no mess to clean up, it becomes a much more difficult and tedious task during the middle of the night when the caregiver or parent has been awoken from their sleep. First, the person sleeping in the bed has to be removed from the bed and, if necessary, cleaned up. If the sleeping person is elderly with limited mobility, this can be a very difficult and, possibly, messy task. Then, once the bed linens and mattress pad have been removed, the caregiver or parent has to remake the bed and get the person who had been sleeping in the bed back into bed.  
         [0004]     Prior patents, such as U.S. Pat. No. 3,570,026 to Allison and U.S. Pat. Nos. 4,922,565 and 5,086,530 to Blake, disclose easily changeable top layers for use with cribs. However, such prior patents do not discuss or suggest using multiple moisture proof layers in a sheet assembly to provide continuing protection to the mattress, even after the top layer of the sheet assembly has been soiled and removed.  
         [0005]     Accordingly, there is a need for a mattress protector that provides multiple layers of protection so that if a top moisture proof layer gets soiled, it can be easily removed, and the mattress protector will continue to protect the mattress while a user continues to use the mattress.  
       SUMMARY  
       [0006]     In accordance with one aspect of the present invention, a multiple layer mattress protector includes a top moisture proof layer; a bottom moisture barrier assembly having an assembly retaining sidewall, a bottom moisture proof layer connected to the retaining sidewall and a non-scratchy surface layer disposed on top of the bottom moisture proof layer and a releasable fastener, wherein the releasable fastener releasably attaches the top moisture proof layer to the bottom moisture barrier assembly. The releasable fastener may be formed as a number of releasable fastener segments, where the releasable fastener segments may be zippers, snaps or Velcro®. The top moisture proof layer and the bottom moisture barrier assembly of the mattress protector may be sized to fit a crib mattress. The bottom moisture proof layer and the non-scratchy surface layer may be constructed integral to one another.  
         [0007]     According to another aspect of the present invention, a multiple layer mattress protector includes a top moisture proof layer having two long sides; a bottom moisture barrier assembly having two long sides and having an assembly retaining sidewall, a bottom moisture proof layer connected to the retaining sidewall and a non-scratchy surface layer disposed on top of the bottom moisture proof layer. The mattress protector also has a first zipper which is connected to one long side of the top moisture proof layer and also connected to one long side of the bottom moisture barrier assembly, and a second zipper connected to the other long side of the top moisture proof layer and also connected to the other long side of the bottom moisture barrier assembly; wherein the first and second zippers releasably attach the top moisture proof layer to the bottom moisture barrier assembly. The top moisture proof layer and the bottom moisture barrier assembly of the mattress protector may be sized to fit a crib mattress. The bottom moisture proof layer and the non-scratchy surface layer may be constructed integral to one another.

     DETAILED DESCRIPTION  
       [0014]     Referring to  FIGS. 1-3 , an embodiment of a multiple layer mattress protector  10  of the present invention is depicted. The mattress protector  10  is shown disposed over a mattress  22  seated on a bed frame  20 , and a sheet  51  is shown placed over the mattress protector  10 . It should be understood that the mattress protector  10  of the present invention may be used with any size mattress  22 . A user may place his own sheet  51  over the mattress protector  10 . The mattress protector  10  of this embodiment includes a top moisture proof layer  25  and a bottom moisture barrier assembly  24 . A pair of releasable fasteners  55   a ,  55   b  connects the top moisture proof layer  25  to the bottom moisture barrier assembly  24 . In this embodiment, the releasable fasteners  55   a ,  55   b  are zippers, but it should be understood that other types of releasable fasteners may be employed as well (e.g. hook and loop type fasteners (Velcro®), snaps, etc.). Also, a pair of releasable fasteners  55   a ,  55   b  is shown, but it should be understood that a single releasable fastener or other variants of multiple fasteners could be employed as well.  
         [0015]     In this embodiment, the bottom moisture barrier assembly  24  includes an assembly retaining sidewall  45 , a non-scratchy surface layer  40  and a bottom moisture proof layer  30  ( FIG. 3 ). The assembly retaining sidewall  45  in this embodiment is made of a stretchable, elastic material. To place the mattress protector  10  on the mattress  22 , the sidewall  45  is stretched around and pulled down the sides of the mattress  22 . The sidewall  45  holds the mattress protector  10  in place. In this embodiment, the bottom moisture proof layer  30  and the top moisture proof layer  25  are constructed of a soft pliable waterproof cotton-like material. It should be understood that both moisture proof layers  25 ,  30  may be constructed from any water proof material. It should also be understood that more than two moisture proof layers may be utilized. The invention is not limited to just the use of two moisture proof layers as described in this embodiment. In this embodiment, the non-scratchy surface layer  40  is a cotton sheet and provides a smooth, comfortable surface for a user of the mattress protector to sleep on. It should be understood that other materials or fabrics besides cotton may be used for the surface layer  40  and that although the surface layer  40  and the bottom moisture proof layer  30  are described as separate layers, it is conceivable that the two could be constructed integral with one another.  
         [0016]     Referring to  FIGS. 3-6 , the mattress protector  10  is shown in use. In  FIG. 3 , the bed is made up with the mattress protector  10  on the mattress  22  and a sheet  5   1  covering the mattress protector  10 . A person  15  is shown lying on the mattress  22 . Though not shown, but as is typical, another sheet, as well as a blanket, could be placed on top of the person  15 . Referring to  FIG. 4 , the person  15  has soiled the bed in some fashion, and the caregiver is taking off the top soiled sheet  51  and top moisture proof layer  25  without needing to remove the person  15  from the bed. Although, the person  15  is still depicted as being in the bed when the sheet  51  and the top moisture proof layer  25  are removed, it should be understood that the caregiver could obviously remove the person  15  from the bed as well if desired. To remove the top moisture proof layer  25 , the caregiver unzips the fastener  55   b  and, while rotating the person  15  upward as arrow  60  depicts, pushes the top moisture proof layer  25 , along with the sheet  51 , under the person  15  as arrow  65  depicts. Then, referring to  FIG. 5 , the caregiver rotates the person  15  in the other direction as arrow  70  depicts and continues to move the sheet  51  and the top moisture layer  25  towards the other edge of the mattress  22  as arrow  65  depicts. The caregiver can then unzip the other fastener  55   a  on the other side of the top moisture layer  25  to disconnect the soiled top moisture layer  25  from the bottom moisture barrier assembly  24 . As shown in  FIG. 6 , the person  15  can be set back down on the top non-scratchy surface layer  40  of the mattress protector  10  and can continue sleeping. The mattress  22  is still protected by bottom moisture proof layer  30 . The caregiver did not have to re-make the entire bed. The soiled sheet  51  and the top moisture layer  25  have been removed and may be laundered when convenient for the caregiver, allowing the caregiver to go back to sleep as well, if desired.  
         [0017]     In another embodiment, the mattress  22  may be a crib mattress, and the releasable fasteners  55   a ,  55   b  of the mattress protector  10  may be snaps instead of zippers. In such an embodiment, when the sheet  51  and the top moisture proof layer  25  are soiled, the top moisture proof layer  25  may be easily removed by the parent while still attending to the child. The parent may hold the child in one hand and unsnap the snaps  55   a ,  55   b  to remove the top moisture proof layer  25  from the bottom moisture barrier assembly  24 .
