Compressible mattress
Compressible mattress assemblies for bed in a box applications consist of a first polymeric foam layer and a second polymeric foam layer, wherein the first polymeric foam layer has a thickness less than the second polymeric foam layer and has a property and/or a foam material that is different from the second polymeric foam layer. In other embodiments, the compressible mattress assemblies consist of a pocketed microcoil array intermediate the first and second polymeric foam layers.
