Abstract: Embodiments disclosed herein include mattress assemblies and components employing passageways for ventilation and airflow. A mattress may contain a mattress core to provide cushioning and support. For example, the mattress core may comprise an innerspring, air bladder(s), and/or foam layer(s). A mattress assembly may include a foam base and/or at least one foam side support member to at least partially surround a mattress core to provide cushioning and structure. The foam base and/or at least one foam side support member may include at least one passageway for facilitating diffusion and air exchange between an exterior environment and an interior space of the enclosure containing the mattress core. In this manner, as stagnant air and humidity developing in the mattress core may be avoided or reduced from the mattress core, which may otherwise cause unhealthy conditions or unpleasant odors for users.

Abstract: Interlocking foam encasement components to form mattress encasements, and related mattress encasements, mattress assemblies, and methods are disclosed. A mattress encasement is formed by two interlocking foam encasement components engaged with each other. Each interlocking foam encasement component includes a foam base member with two foam side-support members provided in parallel or substantially parallel arrangement on opposite sides of the foam base member. To form the mattress encasement, first side-support members of a first interlocking foam encasement component are interlocked orthogonal or substantially orthogonal to second side-support members of a second interlocking foam encasement component to form a foam side-support perimeter for the mattress encasement. The foam side-support perimeter provides an interior area to receive and encase a mattress innerspring or mattress core.

Abstract: Mattress assemblies and methods employing foam side support members and cloth members to enclose mattress cores are disclosed. A mattress may include a mattress assembly enclosing a mattress core. The foam side supports of the mattress assembly may be disposed adjacent to a periphery portion of the mattress core to provide additional support, for example, when a user mounts and dismounts from the mattress. The side support members may be thermally bonded to the cloth members to secure the side supports adjacent the periphery portion of the mattress core. In this manner, the side support members may be precisely positioned relative to the mattress core without the need for adhesives or expensive manufacturing equipment to thermally weld the side support members directly to a foam base.
