Abstract
In many aspects, the systems and methods described herein include a mattress having a top sleeping layer disposed on top of a support layer. The support layer includes a polyurethane foam having channels aligned with the joints of the articulated sections of the foundation or frame of the adjustable bedding assembly. When the sections articulate about the joints, the channels allow the overlying top layer to conform to the sections while reducing wear and tear therein.
