Mattresses including stacked elastomeric layers and related methods for same

A cushion assembly, comprising:

• a coil layer comprising a plurality of coils;
• a first intermediate layer disposed over an upper surface of the coil layer;
• a first buckling layer positioned above the first intermediate layer and having a first plurality of interconnected walls defining a first plurality of voids;
• a second buckling layer disposed over an upper surface of the first buckling layer such that the first and second buckling layers are arranged in a stacked arrangement, the second buckling layer having a second plurality of interconnected walls defining a second plurality of voids;
• a second intermediate layer disposed over an upper surface of the second buckling layer;
• and
• a microgrid layer comprising substantially planar top and bottom surfaces that is disposed over and vertically above an upper surface of the second intermediate layer, the microgrid layer having a third plurality of interconnected walls defining a third plurality of voids, the third plurality of interconnected walls being offset at an angle from the second plurality of interconnected walls, and the third plurality of voids being smaller in thickness and width than the second plurality of voids.

A cushion assembly, comprising:
