Interchangable modular mattress

Abstract

An interchangeable modular mattress is provided. The modular mattress has a first unit and a second unit. A securing means may temporarily secure the first unit to the second unit. The first unit rests on a bed frame, such as a hospital bed frame, and the second unit is secured on top of the first unit. The second unit is replaceable with an alternative second unit which may have a different function or feature, but is generally the same size and shape of the replaced second unit. Firm sides of the first unit reduce the chances of a person accidently falling off the mattress.

I claim: 
     
         1 . A modular mattress comprising:
 a first unit having a front, a back, a first side, a second side, a top and a bottom;   a second unit having a front, a back, a first side, a second side, a top and a bottom; and   wherein the first unit and the second unit are removably secured together via a securing mechanism.   
     
     
         2 . The modular mattress of  claim 1  wherein the securing mechanism is a hook and loop fastener system. 
     
     
         3 . The modular mattress of  claim 1  wherein the securing mechanism is a button. 
     
     
         4 . The modular mattress of  claim 1  wherein the first side and the second side of the bottom of the first unit are tapered. 
     
     
         5 . The modular mattress of  claim 1  wherein the first side and the second side of the first unit are firmer than the second unit. 
     
     
         6 . The modular mattress of  claim 1  wherein the first unit has a central channel wherein the central channel of the first unit receives an extended ridge of the second unit. 
     
     
         7 . The modular mattress of  claim 1  further comprising a coating added to the second unit wherein the coating protects the second unit. 
     
     
         8 . The modular mattress of  claim 1  further comprising:
 a sensor secured to the second unit wherein the sensor determines an environmental condition of the mattress. 
 
     
     
         9 . The modular mattress of  claim 1  further comprising:
 a control unit wherein the control unit is capable of controlling an environmental condition of the mattress. 
 
     
     
         10 . A modular mattress comprising:
 a first unit having a front, a back, a first side, a second side, a top and a bottom;   a second unit having a front, a back, a first side, a second side, a top and a bottom;   wherein the second unit has multiple independent components; and   wherein the first unit and the second unit are removably secured together via a securing mechanism.   
     
     
         11 . The modular mattress of  claim 10  wherein the securing mechanism is a hook and loop fastener system. 
     
     
         12 . The modular mattress of  claim 10  wherein the securing mechanism is a button. 
     
     
         13 . The modular mattress of  claim 10  wherein the first side and the second side of the bottom of the first unit are tapered. 
     
     
         14 . The modular mattress of  claim 10  wherein the first side and the second side of the first unit are firmer than the second unit. 
     
     
         15 . The modular mattress of  claim 10  wherein the first unit has a central channel wherein the central channel of the first unit receives an extended ridge of the second unit. 
     
     
         16 . The modular mattress of  claim 10  further comprising a coating added to the second unit wherein the coating protects the second unit. 
     
     
         17 . The modular mattress of  claim 10  further comprising:
 a sensor secured to the second unit wherein the sensor determines an environmental condition of the mattress. 
 
     
     
         18 . The modular mattress of  claim 10  further comprising:
 a control unit wherein the control unit is capable of controlling an environmental condition of the mattress. 
 
     
     
         19 . The modular mattress of  claim 10  wherein the multiple components of the second unit are not identical.
